Since 2010, array-CGH (aCGH) has been the first-tier test in the diagnostic approach of children with neurodevelopmental disorders (NDD) or multiple congenital anomalies (MCA) of unknown origin. Its broad application led to the detection of numerous variants of uncertain clinical significance (VOUS). How to appropriately interpret aCGH results represents a challenge for the clinician. We present a retrospective study on 293 patients with age range 1 month - 29 years (median 7 years) with NDD and/or MCA and/or dysmorphisms, investigated through aCGH between 2005 and 2016. The aim of the study was to analyze clinical and molecular cytogenetic data in order to identify what elements could be useful to interpret unknown or poorly described aberrations. Comparison of phenotype and cytogenetic characteristics through univariate analysis and multivariate logistic regression was performed. Copy number variations (CNVs) with a frequency < 1% were detected in 225 patients of the total sample, while 68 patients presented only variants with higher frequency (heterozygous deletions or amplification) and were considered to have negative aCGH. Proved pathogenic CNVs were detected in 70 patients (20.6%). Delayed psychomotor development, intellectual disability, intrauterine growth retardation (IUGR), prematurity, congenital heart disease, cerebral malformations and dysmorphisms correlated to reported pathogenic CNVs. Prematurity, ventricular septal defect and dysmorphisms remained significant predictors of pathogenic CNVs in the multivariate logistic model whereas abnormal EEG and limb dysmorphisms were mainly detected in the group with likely pathogenic VOUS. A flow-chart regarding the care for patients with NDD and/or MCA and/or dysmorphisms and the interpretation of aCGH has been made on the basis of the data inferred from this study and literature. Our work contributes to make the investigative process of CNVs more informative and suggests possible directions in aCGH interpretation and phenotype correlation.

Using whole-exome sequencing, we have identified novel de novo heterozygous pleckstrin homology domain-interacting protein ( PHIP ) variants that are predicted to be deleterious, including a frameshift deletion, in two unrelated patients with common clinical features of developmental delay, intellectual disability, anxiety, hypotonia, poor balance, obesity, and dysmorphic features. A nonsense mutation in PHIP has previously been associated with similar clinical features. Patients with microdeletions of 6q14.1, including PHIP , have a similar phenotype of developmental delay, intellectual disability, hypotonia, and obesity, suggesting that the phenotype of our patients is a result of loss-of-function mutations. PHIP produces multiple protein products, such as PHIP1 (also known as DCAF14), PHIP, and NDRP. PHIP1 is one of the multiple substrate receptors of the proteolytic CUL4-DDB1 ubiquitin ligase complex. CUL4B deficiency has been associated with intellectual disability, central obesity, muscle wasting, and dysmorphic features. The overlapping phenotype associated with CUL4B deficiency suggests that PHIP mutations cause disease through disruption of the ubiquitin ligase pathway.

Body dysmorphic disorder (BDD) is a distressing psychiatric disorder. So far there have not been any studies on BDD in Saudi Arabia. The aim of this study was to determine the prevalence of body dysmorphic disorder in female medical students and to investigate whether there is an association between BDD and body features of concern, social anxiety and symptoms of BDD. A cross sectional study was carried out on female medical students of the college of medicine, King Saud University, Riyadh, Saudi Arabia during January to April, 2015. Data were collected using the body image disturbance questionnaire, Body dysmorphic disorder symptomatology and social interaction anxiety scale. Descriptive statistics, bivariate and multivariate analysis were used to analyze the results. Out of 365 students who filled out the questionnaire, 4.4% (95% confidence intervals (CI): 2.54% to 7.04%) were positive for BDD with skin (75%) and fat (68.8%) as the most frequent body features of concern. Ten features (skin, fat, chest, hips, buttocks, arms, legs, lips, fingers, and shoulders) out of twenty-six were significantly associated with BDD. Arms and chest were independently associated with BDD. The odds of presence of body concern related to "arms" was 4.3 (95% C.I: 1.5, 12.1) times more in BDD subjects than non-BDD subjects, while concern about "chest" was 3.8 (1.3, 10.9) times more when compared to non-BDD subjects. No statistically significant association was observed between BDD and social anxiety (P = 0.13). This was the first study conducted in Kingdom of Saudi Arabia (KSA) on female medical students, which quantified the prevalence of BDD and identified the body features associated with it. Body dysmorphic disorder is prevalent in female medical students but it is relatively rare and an unnoticed disorder.

Body dysmorphic disorder (BDD) shares many characteristics with social phobia (SP), including high levels of social anxiety and avoidance, but to our knowledge no studies have directly compared these disorders’ demographic and clinical features. Demographic and clinical features were compared in individuals with BDD (n=172), SP (n=644), and comorbid BDD/SP (n=125). SP participants had a significantly earlier age of onset and lower educational attainment than BDD participants. BDD participants were significantly less likely to ever be married than SP participants, had a greater likelihood of ever being psychiatrically hospitalized, and had significantly lower mean GAF scores than SP participants. The two groups had different comorbidity patterns, which included a greater likelihood for BDD participants to have comorbid obsessive-compulsive disorder (OCD) or an eating disorder, versus a greater likelihood for SP participants to have a comorbid non-OCD anxiety disorder. The comorbid BDD/SP group had significantly greater morbidity across several domains than the SP only group, but not the BDD only group. In summary, although BDD and SP were similar across many demographic and clinical features, they had important differences. Future studies are needed to confirm these findings and address similarities and differences between these disorders across a broader range of variables. PMID:22999105

Accurate Detection of Dysmorphic Nuclei Using Dynamic Programming and Supervised Classification.

A vast array of pathologies is typified by the presence of nuclei with an abnormal morphology. Dysmorphic nuclear phenotypes feature dramatic size changes or foldings, but also entail much subtler deviations such as nuclear protrusions called blebs. Due to their unpredictable size, shape and intensity, dysmorphic nuclei are often not accurately detected in standard image analysis routines. To enable accurate detection of dysmorphic nuclei in confocal and widefield fluorescence microscopy images, we have developed an automated segmentation algorithm, called Blebbed Nuclei Detector (BleND), which relies on two-pass thresholding for initial nuclear contour detection, and an optimal path finding algorithm, based on dynamic programming, for refining these contours. Using a robust error metric, we show that our method matches manual segmentation in terms of precision and outperforms state-of-the-art nuclear segmentation methods. Its high performance allowed for building and integrating a robust classifier that recognizes dysmorphic nuclei with an accuracy above 95%. The combined segmentation-classification routine is bound to facilitate nucleus-based diagnostics and enable real-time recognition of dysmorphic nuclei in intelligent microscopy workflows.

The NR2F2 gene plays an important role in angiogenesis and heart development. Moreover, this gene is involved in organogenesis in many other organs in mouse models. Variants in this gene have been reported in a number of patients with nonsyndromic atrioventricular septal defect, and in one patient with congenital heart defect and dysmorphic features. Here we report an 11-month-old Caucasian male with global developmental delay, dysmorphic features, coarctation of the aorta, and ventricular septal defect. He was later found to have a pathogenic mutation in the NR2F2 gene by whole exome sequencing. This is the second instance in which an NR2F2 mutation has been identified in a child with a congenital heart defect and other anomalies. This case suggests that some variants in NR2F2 may cause syndromic forms of congenital heart defect. © 2018 Wiley Periodicals, Inc.

Epilepsy is one of the most common findings in chromosome aberrations. Types of seizures and severity may significantly vary both between different conditions and within the same aberration. Hitherto specific seizures and EEG patterns are identified for only few syndromes. We studied 74 patients with defined genetic-dysmorphic syndromes with and without epilepsy in order to assess clinical and electroencephalographic features, to compare our observation with already described electro-clinical phenotypes, and to identify putative electroencephalographic and/or seizure characteristics useful to address the diagnosis. In our population, 10 patients had chromosomal disorders, 19 microdeletion or microduplication syndromes, and 32 monogenic syndromes. In the remaining 13, syndrome diagnosis was assessed on clinical grounds. Our study confirmed the high incidence of epilepsy in genetic-dysmorphic syndromes. Moreover, febrile seizures and neonatal seizures had a higher incidence compared to general population. In addition, more than one third of epileptic patients had drug-resistant epilepsy. EEG study revealed poor background organization in 42 patients, an excess of diffuse rhythmic activities in beta, alpha or theta frequency bands in 34, and epileptiform patterns in 36. EEG was completely normal only in 20 patients. No specific electro-clinical pattern was identified, except for inv-dup15, Angelman, and Rett syndromes. Nevertheless some specific conditions are described in detail, because of notable differences from what previously reported. Regarding the diagnostic role of EEG, we found that--even without any epileptiform pattern--the generation of excessive rhythmic activities in different frequency bandwidths might support the diagnosis of a genetic syndrome. © 2014 Wiley Periodicals, Inc.

To correlate clinical examination with underlying genotype in asymptomatic females who are potential carriers of X-linked developmental cataract (Nance-Horan syndrome). An ophthalmologist blind to the pedigree performed comprehensive ophthalmic examination for 16 available family members (two affected and six asymptomatic females, five affected and three asymptomatic males). Facial features were also noted. Venous blood was collected for sequencing of the gene NHS. All seven affected family members had congenital or infantile cataract and facial dysmorphism (long face, bulbous nose, abnormal dentition). The six asymptomatic females ranged in age from 4-35 years old. Four had posterior Y-suture centered lens opacities; these four also exhibited the facial dysmorphism of the seven affected family members. The fifth asymptomatic girl had scattered fine punctate lens opacities (not centered on the Y-suture) while the sixth had clear lenses, and neither exhibited the facial dysmorphism. A novel NHS mutation (p.Lys744AsnfsX15 [c.2232delG]) was found in the seven patients with congenital or infantile cataract. This mutation was also present in the four asymptomatic girls with Y-centered lens opacities but not in the other two asymptomatic girls or in the three asymptomatic males (who had clear lenses). Lens opacities centered around the posterior Y-suture in the context of certain facial features were sensitive and specific clinical signs of carrier status for NHS mutation in asymptomatic females. Lens opacities that did not have this characteristic morphology in a suspected female carrier were not a carrier sign, even in the context of her affected family members.

Human immunodeficiency virus type I enhancer binding protein 2 (HIVEP2) has been previously associated with intellectual disability and developmental delay in three patients. Here, we describe six patients with developmental delay, intellectual disability, and dysmorphic features with de novo likely gene-damaging variants in HIVEP2 identified by whole-exome sequencing (WES). HIVEP2 encodes a large transcription factor that regulates various neurodevelopmental pathways. Our findings provide further evidence that pathogenic variants in HIVEP2 lead to intellectual disabilities and developmental delay.

Dominant inheritance of cerebral gigantism.

Cerebral gigantism is a syndrome consisting of characteristic dysmorphic features, accelerated growth in early childhood, and variable degrees of mental retardation. Its etiology and pathogenesis have not been defined. Three families are presented with multiple affected members. The vertical transmission of the trait and equal expression in both sexes in these families indicates a genetic etiology with a dominant pattern of inheritance, probably autosomal. As in previously reported cases, extensive endocrine evaluation failed to define the pathogenesis of the accelerated growth present in this disorder.

Comparison of facial features of DiGeorge syndrome (DGS) due to deletion 10p13-10pter with DGS due to 22q11 deletion

DiGeorge syndrome (DGS) is a congenital anomaly consisting of cardiac defects, aplasia or hypoplasia of the thymus and parathroid glands, and dysmorphic facial features. The majority of DGS cases have a submicroscopic deletion within chromosome 22q11. However there have been a number of reports of DGS in association with other chromosomal abnormalities including four cases with chromosome 10p deletions. We describe a further 10p deletion case and suggest that the facial features in children with DGS due to deletions of 10p are different from those associated with chromosome 22 deletions. The propositus was born at 39 weeks gestation to unrelatedmore » caucasian parents, birth weight 2580g (10th centile) and was noted to be dysmorphic and cyanosed shortly after birth. The main dysmorphic facial features were a broad nasal bridge with very short palpebral fissures. Echocardiography revealed a large subsortic VSD and overriding aorta. She had a low ionised calcium and low parathroid hormone level. T cell subsets and PHA response were normal. Abdominal ultrasound showed duplex kidneys and on further investigation she was found to have reflux and raised plasma creatinine. She had an anteriorly placed anus. Her karyotype was 46,XX,-10,+der(10)t(3;10)(p23;p13)mat. The dysmorphic facial features in this baby are strikingly similar to those noted by Bridgeman and Butler in child with DGS as the result of a 10p deletion and distinct from the face seen in children with DiGeorge syndrome resulting from interstitial chromosome 22 deletions.« less

Cosmetic Professionals' Awareness of Body Dysmorphic Disorder.

Preoccupation with a perceived appearance flaw is the main feature of body dysmorphic disorder. The majority of these patients seek and often receive some sort of cosmetic procedure, although this condition is considered to be a contraindication. This study evaluates cosmetic professionals' recognition of body dysmorphic disorder and the way they act on this. Members of Dutch professional associations for aesthetic plastic surgery, dermatology, and cosmetic medicine received an online survey by means of their association's digital mailing lists; the survey was completed by 173 respondents. Most participants indicated being more or less familiar with the diagnostic criteria and clinical picture of body dysmorphic disorder. Approximately two-thirds of the participants reported that they had encountered between one and five of these patients in their practice over the past year, a percentage that is significantly lower than the estimated prevalence of body dysmorphic disorder. The majority of professionals sometimes or often address body image problems during consultation, most of them collaborate with psychologists or psychiatrists when encountering a patient with body dysmorphic disorder, and approximately 70 percent had refused to perform a procedure in such a patient. Our results converge with those of previous studies, showing that most cosmetic professionals have some degree of awareness of body dysmorphic disorder, although the number they report encountering in clinical practice departs from prevalence figures. When a patient is identified as having body dysmorphic disorder, the professionals use this knowledge to guide their decision to perform a cosmetic procedure.

Dysmorphic syndromes have different facial malformations. These malformations are significant to an early diagnosis of dysmorphic syndromes and contain distinctive information for face recognition. In this study we define the certain features of each syndrome by considering facial malformations and classify Fragile X, Hurler, Prader Willi, Down, Wolf Hirschhorn syndromes and healthy groups automatically. The reference points are marked on the face images and ratios between the points' distances are taken into consideration as features. We suggest a neural network based hierarchical decision tree structure in order to classify the syndrome types. We also implement k-nearest neighbor (k-NN) and artificial neural network (ANN) classifiers to compare classification accuracy with our hierarchical decision tree. The classification accuracy is 50, 73 and 86.7% with k-NN, ANN and hierarchical decision tree methods, respectively. Then, the same images are shown to a clinical expert who achieve a recognition rate of 46.7%. We develop an efficient system to recognize different syndrome types automatically in a simple, non-invasive imaging data, which is independent from the patient's age, sex and race at high accuracy. The promising results indicate that our method can be used for pre-diagnosis of the dysmorphic syndromes by clinical experts.

We identified five unrelated individuals with significant global developmental delay and intellectual disability (ID), dysmorphic facial features and frequent microcephaly, and de novo predicted loss-of-function variants in chromosome alignment maintaining phosphoprotein 1 (CHAMP1). Our findings are consistent with recently reported de novo mutations in CHAMP1 in five other individuals with similar features. CHAMP1 is a zinc finger protein involved in kinetochore-microtubule attachment and is required for regulating the proper alignment of chromosomes during metaphase in mitosis. Mutations in CHAMP1 may affect cell division and hence brain development and function, resulting in developmental delay and ID.

Rhinoplasty is one of the most sought-after esthetic operations among individuals with body dysmorphic disorder. The aim of this study was to cross-culturally adapt and validate the Body Dysmorphic Symptoms Scale. Cross-cultural validation study conducted in a plastic surgery outpatient clinic of a public university hospital. Between February 2014 and March 2015, 80 consecutive patients of both sexes seeking rhinoplasty were selected. Thirty of them participated in the phase of cultural adaptation of the instrument. Reproducibility was tested on 20 patients and construct validity was assessed on 50 patients, with correlation against the Yale-Brown Obsessive Compulsive Scale for Body Dysmorphic Disorder. The Brazilian version of the instrument showed Cronbach's alpha of 0.805 and excellent inter-rater reproducibility (intraclass correlation coefficient, ICC = 0.873; P < 0.001) and intra-rater reproducibility (ICC = 0.939; P < 0.001). Significant differences in total scores were found between patients with and without symptoms (P < 0.001). A strong correlation (r = 0.841; P < 0.001) was observed between the Yale-Brown Obsessive Compulsive Scale for Body Dysmorphic Disorder and the Body Dysmorphic Symptoms Scale. The area under the receiver operating characteristic curve was 0.981, thus showing good accuracy for discriminating between presence and absence of symptoms of body dysmorphic disorder. Forty-six percent of the patients had body dysmorphic symptoms and 54% had moderate to severe appearance-related obsessive-compulsive symptoms. The Brazilian version of the Body Dysmorphic Symptoms Scale is a reproducible instrument that presents face, content and construct validity.

The present study aimed to investigate chromosomal microarray (CMA) and clinical data in patients with unexplained developmental delay/intellectual disability (DD/ID) accompanying dysmorphism, congenital anomalies, or epilepsy. We also aimed to evaluate phenotypic clues in patients with pathogenic copy number variants (CNVs). We collected clinical and CMA data from patients at Konyang University Hospital between September 2013 and October 2014. We included patients who had taken the CMA test to evaluate the etiology of unexplained DD/ID. All of the 50 patients identified had DD/ID. Thirty-nine patients had dysmorphism, 19 patients suffered from epilepsy, and 12 patients had congenital anomalies. Twenty-nine of the 50 patients (58%) showed abnormal results. Eighteen (36%) were considered to have pathogenic CNVs. Dysmorphism (p=0.028) was significantly higher in patients with pathogenic CNVs than in those with normal CMA. Two or more clinical features were presented by 61.9% (13/21) of the patients with normal CMA and by 83.3% (15/18) of the patients with pathogenic CMA. Dysmorphism can be a phenotypic clue to pathogenic CNVs. Furthermore, pathogenic CNV might be more frequently found if patients have two or more clinical features in addition to DD/ID. © Copyright: Yonsei University College of Medicine 2018.

Noonan Syndrome is an autosomal dominant disorder characterized by short stature, congenital heart defects, developmental delay, dysmorphic facial features and occasional lymphatic dysplasias. The features of Noonan Syndrome change with age and have variable expression. The diagnosis has historically been based on clinical grounds. We describe a child that was born with congenital refractory chylothorax and subcutaneous edema suspected to be secondary to pulmonary lymphangiectasis. The infant died of respiratory failure and anasarca at 80 days. The autopsy confirmed lymphatic dysplasia in lungs and mesentery. The baby had no dysmorphic facial features and was diagnosed postmortem with Noonan syndrome by genomic DNA sequence analysis as he had a heterozygous mutation for G503R in the PTPN11 gene.

To examine the variation in significant dysmorphic features in children from 3 different populations with the most dysmorphic forms of fetal alcohol spectrum disorders, fetal alcohol syndrome (FAS), and partial fetal alcohol syndrome (PFAS). Advanced multiple regression techniques are used to determine the discriminating physical features in the diagnosis of FAS and PFAS among children from Northern Plains Indian communities, South Africa, and Italy. Within the range of physical features used to identify children with fetal alcohol spectrum disorders, specifically FAS and PFAS, there is some significant variation in salient diagnostic features from one population to the next. Intraclass correlations in diagnostic features between these 3 populations is 0.20, indicating that about 20% of the variability in dysmorphology core features is associated with location and, therefore, specific racial/ethnic population. The highly significant diagnostic indicators present in each population are identified for the full samples of FAS, PFAS, and normals and also among children with FAS only. A multilevel model for these populations combined indicates that these variables predict dysmorphology unambiguously: small palpebral fissures, narrow vermillion, smooth philtrum, flat nasal bridge, and fifth finger clinodactyly. Long philtrum varies substantially as a predictor in the 3 populations. Predictors not significantly related to fetal alcohol spectrum disorders dysmorphology across the 3 populations are centile of height (except in Italy) strabismus, interpupilary distance, intercanthal distance, and heart murmurs. The dysmorphology associated with FAS and PFAS vary across populations, yet a particular array of common features occurs in each population, which permits a consistent diagnosis across populations.

Nasal aesthetic deformities may be associated with significant body image dissatisfaction. The only diagnostic category in the current list of psychiatric disorders that directly addresses these concerns is body dysmorphic disorder. This large-scale study determined the prevalence of body dysmorphic disorder and its symptoms in patients seeking rhinoplasty and evaluated the clinical profile of these patients. Two hundred twenty-six patients were given questionnaires including demographic characteristics, visual analogue scales for nasal shape, the Yale-Brown Obsessive Compulsive Scale modified for body dysmorphic disorder to assess severity of symptoms, a generic quality-of-life questionnaire, and the Derriford Appearance Scale 59, to assess appearance-related disruption of everyday living. Independent observers scored the nasal shape. Thirty-three percent of patients showed at least moderate symptoms of body dysmorphic disorder. Aesthetic goals (p < 0.001), revision rhinoplasty (p = 0.003), and psychiatric history (p = 0.031) were associated with more severe symptoms. There was no correlation between the objective and subjective scoring of the nasal shape. Yale-Brown scale modified for body dysmorphic disorder scores correlated inversely with the subjective nasal scoring (n = 210, p < 0.001), without relation to the objective deformity of the nose. Body dysmorphic disorder symptoms significantly reduced the generic quality of life (n = 160, p < 0.001) and led to significant appearance-related disruption of everyday living (n = 161, p < 0.001). The prevalence of moderate to severe body dysmorphic disorder symptoms in an aesthetic rhinoplasty population is high. Patients undergoing revision rhinoplasty and with psychiatric history are particularly at risk. Body dysmorphic disorder symptoms significantly reduce the quality of life and cause significant appearance-related disruption of everyday living. Risk, III.

We report a 22-year-old male patient with pharmacoresistant epilepsy, mental retardation and dysmorphisms. Standard cytogenetic analysis revealed a de novo interstitial duplication of the short arm of chromosome 11 (11p). High density array-CGH analysis showed that the rearrangement spans about 35Mb on chromosome 11p12-p15.4. Duplications of 11p are rare and usually involve the distal part of the chromosome arm (11p15), being not associated with epilepsy, whereas our patient showed a unique epileptic phenotype associated with mental retardation and dysmorphic features. The role of some rearranged genes in epilepsy pathogenesis in this patient is also discussed.

Body image concern and selective attention to disgusting and non-self appearance-related stimuli.

PubMed

Onden-Lim, Melissa; Wu, Ray; Grisham, Jessica R

2012-09-01

Although selective attention to one's own appearance has been widely documented in studies of body dysmorphic disorder (BDD), little is known about attentional bias toward non-self appearance-related stimuli in BDD. Furthermore, despite reports of heightened experience of disgust in BDD, it is unknown whether these individuals differentially attend to disgusting stimuli and whether disgust is important in processing of unattractive stimuli. We used a dot probe procedure to investigate the relationship between dysmorphic concern, a defining feature of BDD, and selective attention to faces, attractive, unattractive and disgusting images in a female heterosexual student population (N=92). At the long stimulus presentation (1000 ms), dysmorphic concern was positively associated with attention to faces in general and attractive appearance-related images. In contrast, at the short stimulus presentation (200 ms), there was a positive association between dysmorphic concern and disgusting images. Implications for theoretical models of BDD are discussed.

We report two patients with Leigh syndrome that showed a combination of facial dysmorphism and MRI imaging indicating an SURF1 deficiency, which was confirmed by sequence analysis. Case 1 is a 3-year-old girl with failure to thrive and developmental delay. She presented with tachypnea at rest and displayed facial dysmorphism including frontal bossing, lateral displacement of inner canthi, esotropia, maxillary hypoplasia, slightly upturned nostril, and hypertrichosis dominant on the forehead and extremities. Case 2 is an 8-year-old boy with respiratory failure. He had been diagnosed as selective complex IV deficiency. Case 2 displayed facial dysmorphism and hypertrichosis. Since both patients displayed characteristic facial dysmorphism and MRI findings, we sequenced the SURF1 gene and identified two heterozygous mutations; c.49+1 G>T and c.752_753del in Case 1, and homozygous c.743 C>A in Case 2. For patients with Leigh syndrome showing these facial dysmorphism and hypertrichosis, sequence analysis of the SURF1 gene may be useful. Copyright © 2012 The Japanese Society of Child Neurology.

1994-09-01

A 41-year-old woman was evaluated for dysmorphic features and mental handicap. Prior karyotyping had revealed 7% mosaicism for trisomy 18 in skin fibroblasts with normal blood chromosomes. Clinical features consisted of short stature, mild mental retardation, sensorineural deafness and the following dysmorphic features: short, broad neck, low posterior hairline, small palpebral fissures with iris coloboma on the right, epicanthic folds, small mouth, high palate and prominent mandible, short metacarpals and digits, particularly the fifth, with bilateral simian creases. Medical problems included non-insulin dependent diabetes mellitus, hypertension, oligomenorrhea and recent onset of diabetic neuropathy and retinal exudates. Head size and brainmore » MRI were within normal limits. Peripheral blood chromosomes revealed: 46,XX (45 cells), 46,XX,t(7;16)(q21;q21) in 1 cell, 45,X (1 cell), 48,XXXX (1 cell), 47,XX,+mar (1 cell), 48,XX,+mar,+mar (1 cell). Skin fibroblasts revealed the following karyotypes: 46,XX (25 cells), 45,X (14 cells), 47,XX,+2 (10 cells) and 47,X,+2,+7 (1 cell). Previously reported cases of mosaic variegated aneuploidy include microcephaly as a prominent feature. Chromosomes involved in the abnormality are variable. Clinical presentations in such patients are not consistent and do not appear to correlate with specific chromosome defects. This patient represents an interesting example of probable mitotic instability disrupting normal developmental processes.« less

Nance-Horan Syndrome (NHS) is a rare X-linked syndrome characterized by congenital cataract which leads to profound vision loss, characteristic dysmorphic features and specific dental anomalies. Microcornea, microphthalmia and mild or moderate mental retardation may accompany these features. Heterozygous females often manifest similarly but with less severe features than affected males. We describe two brothers who have the NHS phenotype and their carrier mother who had microcornea but not cataract. We identified a previously unreported frameshift mutation (c.558insA) in exon 1 of the NHS gene in these patients and their mother which is predicted to result in the incorporation of 11 aberrant amino acids prior to a stop codon (p.E186Efs11X). We also discussed genotype-phenotype correlation according to relevant literature. Copyright © 2013 Elsevier B.V. All rights reserved.

We present a newly recognized, likely autosomal recessive, pleiotropic disorder seen in four individuals (three siblings and their nephew) from a consanguineous family of Pakistani origin. The condition is characterized by hypogonadotropic hypogonadism, severe microcephaly, sensorineural deafness, moderate learning disability, and distinctive facial dysmorphic features. Autozygosity mapping using SNP array genotyping defined a single, large autozygous region of 13.1 Mb on chromosome 3p21 common to the affected individuals. The critical region contains 227 genes and initial sequence analysis of a functional candidate gene has not identified causative mutations. Copyright © 2011 Wiley Periodicals, Inc.

Prior research has not yet investigated the prevalence of body dysmorphic disorder (BDD) in adolescents and young adults based on criteria from the Diagnostic and Statistical Manual of Mental Disorders, fifth edition (DSM-5). In the current study, the point prevalence of BDD, comorbid symptoms, and associated features, such as appearance-related suicidality, level of insight or history of plastic surgeries, were examined in a non-clinical sample of German adolescents and young adults (n=308), between 15 and 21 years old, using self-report measures. Eleven participants (3.6%; 95% CI=[1.9, 5.8]) met DSM-5 criteria for BDD. Self-reported BDD (vs. no-BDD) was related to respondents showing significantly more obsessive-compulsive (OC) symptoms and lower degrees of insight regarding appearance concerns. Significantly more adolescents and young adults with vs. without self-reported BDD (36.4% vs. 8.8%) reported appearance-related suicidal ideation. In conclusion, body dysmorphic symptoms are common in adolescents and young adults and are associated with high rates of comorbid symptoms and suicidal ideation.

Wiedemann-Steiner syndrome is a rare genetic disorder characterized by short stature, hairy elbows, facial dysmorphism, and developmental delay. It can also be accompanied by musculoskeletal anomalies such as muscular hypotonia and small hands and feet. Mutations in the KMT2A gene have only recently been identified as the cause of Wiedemann-Steiner syndrome; therefore, only 16 patients from 15 families have been described, and new phenotypic features continue to be added. In this report, we describe 2 newly identified patients with Wiedemann-Steiner syndrome who presented with variable severity. One girl exhibited developmental dysplasia of the hip and fibromatosis colli accompanied by other clinical features, including facial dysmorphism, hypertrichosis, patent ductus arteriosus, growth retardation, and borderline intellectual disability. The other patient, a boy, showed severe developmental retardation with automatic self-mutilation, facial dysmorphism, and hypertrichosis at a later age. Exome sequencing analysis of these patients and their parents revealed a de novo nonsense mutation, p.Gln1978*, of KMT2A in the former, and a missense mutation, p.Gly1168Asp, in the latter, which molecularly confirmed the diagnosis of Wiedemann-Steiner syndrome.

Childhood autism is a neurodevelopmental disorder characterized by impairments in social interactions, verbal and non-verbal communication and by a pattern of stereotypical behaviors and interests. The aim of this study was to estimate the dysmorphic facial features of children with autism and children with Asperger syndrome. The examination was conducted on 60 children (30 with childhood autism and 30 with Asperger syndrome). The photo anthropometric method used in this study followed the protocol established by Stengel-Rutkowski et al. The performed statistical analysis showed that in patients with childhood autism, the anteriorly rotated ears and the long back of the nose appeared more often. In the group of children with autism, there was a connection between the amount of dysmorphies and the presence of some somatic diseases in the first-degree relatives. There was also a connection between the motor coordination and the age the child began to walk. In patients with childhood autism, there were certain dysmorphies (like the anterior rotated ears and the long back of the nose) which appeared more often. Although the connection was not statistically significant, it seemed to concur with data from the literature. Formulation of the other conclusions would require broader studies e.g. dealing with a familial analysis of dysmorphic features.

Hypoparathyroidism-retardation-Dysmorphism (HRD) syndrome--a review.

2004-12-01

Hypoparathyroidism, retardation, and dysmorphism (HRD) is a newly recognized genetic syndrome, described in patients of Arab origin. The syndrome consists of permanent congenital hypoparathyroidism, severe prenatal and postnatal growth retardation, and profound global developmental delay. The patients are susceptible to severe infections including life-threatening pneumococcal infections especially during infancy. The main dysmorphic features are microcephaly, deep-set eyes or microphthalmia, ear abnormalities, depressed nasal bridge, thin upper lip, hooked small nose, micrognathia, and small hands and feet. A single 12-bp deletion (del52-55) in the second coding exon of the tubulin cofactor E (TCFE) gene, located on the long arm of chromosome 1, is the cause of HRD among Arab patients. Early recognition and therapy of hypocalcemia is important as is daily antibiotic prophylaxis against pneumococcal infections.

The relationship between obsessive-compulsive disorder (OCD) and body dysmorphic disorder (BDD) is unclear. BDD has been proposed to be an OCD-spectrum disorder or even a type of OCD. However, few studies have directly compared these disorders' clinical features. We compared characteristics of subjects with OCD (n=210), BDD (n=45), and comorbid BDD/OCD (n=40). OCD and BDD did not significantly differ in terms of demographic features, age of OCD or BDD onset, illness duration, and many other variables. However, subjects with BDD had significantly poorer insight than those with OCD and were more likely to be delusional. Subjects with BDD were also significantly more likely than those with OCD to have lifetime suicidal ideation, as well as lifetime major depressive disorder and a lifetime substance use disorder. The comorbid BDD/OCD group evidenced greater morbidity than subjects with OCD or BDD in a number of domains, but differences between the comorbid BDD/OCD group and the BDD group were no longer significant after controlling for BDD severity. However, differences between the comorbid BDD/OCD group and the OCD group remained significant after controlling for OCD severity. In summary, OCD and BDD did not significantly differ on many variables but did have some clinically important differences. These findings have implications for clinicians and for the classification of these disorders. (c) 2006 Wiley-Liss, Inc.

Pitt-Hopkins syndrome is characterized by mental retardation, hyperventilation, and dysmorphic features due to TCF4 mutations. We report a case of Pitt-Hopkins syndrome in a 2½-year-old boy presenting with psychomotor retardation, recurrent respiratory tract infections, and dysmorphic features with absence of hyperventilation or other breathing abnormalities. Comparative genomic hybridization and quantitative real-time polymerase chain reaction were used to confirm TCF4 haploinsufficiency. Pitt-Hopkins syndrome is a rare debilitating disease that should be in the differential diagnosis of other neurodevelopmental disorders characterized by mental retardation and hypotonicity despite the absence of hyperapnea and seizures. Quantitative real-time polymerase chain reaction is another method to identify TCF4 and to confirm Pitt-Hopkins syndrome diagnosis.

A novel 19.98-Mb duplication in chromosome Xp22.33p22.12 was detected by array CGH in a 30-year-old man affected by intellectual disability, congenital hypotonia and dysmorphic features. The duplication encompasses more than 100 known genes. Many of these genes (such as neuroligin 4, cyclin-dependent kinase like 5, and others) have already correlated with X-linked intellectual disability and/or neurodevelopmental disorders. Due to the high number of potentially pathogenic genes involved in the reported duplication, we cannot correlate the clinical phenotype to a single gene. Indeed, we suggest that the resulting clinical phenotype may have arisen from the overexpression and consequent perturbation of fine gene dosage. PMID:26997944

2006-01-01

Body dysmorphic disorder (BDD) usually begins during adolescence, but its clinical features have received little investigation in this age group. Two hundred individuals with BDD (36 adolescents; 164 adults) completed interviewer-administered and self-report measures. Adolescents were preoccupied with numerous aspects of their appearance, most often their skin, hair, and stomach. Among the adolescents, 94.3% reported moderate, severe, or extreme distress due to BDD, 80.6% had a history of suicidal ideation, and 44.4% had attempted suicide. Adolescents experienced high rates and levels of impairment in school, work, and other aspects of psychosocial functioning. Adolescents and adults were comparable on most variables, although adolescents had significantly more delusional BDD beliefs and a higher lifetime rate of suicide attempts. Thus, adolescents with BDD have high levels of distress and rates of functional impairment, suicidal ideation, and suicide attempts. BDD’s clinical features in adolescents appear largely similar to those in adults. PMID:16499973

The massa intermedia is an inconstant parenchymal band connecting the medial thalami. It may be thickened in various disease processes such as Chiari II malformation or absent in other disease states. However, the massa intermedia may also be absent in up to 30% of normal human brains. To the best of my knowledge, detailed imaging findings of massa intermedia duplication have only been described in a single case report. An additional case of thalamic massa intermedia duplication discovered on a routine brain MR performed for dysmorphic facial features is reported herein.

Tuberous Sclerosis Complex (TSC) is a genetic hamartoma syndrome frequently associated with severe intractable epilepsy. In some TSC patients epilepsy surgery is a promising treatment option provided that the epileptogenic zone can be precisely delineated. TSC brain lesions (cortical tubers) contain dysmorphic neurons, brightly eosinophilic giant cells and white matter alterations in various proportions. However, a histological classification system has not been established for tubers. Therefore, the aim of this study was to define distinct histological patterns within tubers based on semi-automated histological quantification and to find clinically significant correlations. In total, we studied 28 cortical tubers and seven samples of perituberal cortex from 28 TSC patients who had undergone epilepsy surgery. We assessed mammalian target of rapamycin complex 1 (mTORC1) activation, the numbers of giant cells, dysmorphic neurons, neurons, and oligodendrocytes, and calcification, gliosis, angiogenesis, inflammation, and myelin content. Three distinct histological profiles emerged based on the proportion of calcifications, dysmorphic neurons and giant cells designated types A, B, and C. In the latter two types we were able to subsequently associate them with specific features on presurgical MRI. Therefore, these histopathological patterns provide consistent criteria for improved definition of the clinico-pathological features of cortical tubers identified by MRI and provide a basis for further exploration of the functional and molecular features of cortical tubers in TSC.

Submicroscopic chromosomal rearrangements are the most common identifiable causes of intellectual disability and autism spectrum disorders associated with dysmorphic features. Chromosomal microarray (CMA) can detect copy number variants <1 Mb and identifies size and presence of known genes. The aim of this study was to demonstrate the usefulness of CMA, as a first-tier tool in detecting the etiology of unexplained intellectual disability/autism spectrum disorders (ID/ASDs) associated with dysmorphic features in a large cohort of pediatric patients. We studied 349 individuals; 223 males, 126 females, aged 5 months-19 years. Blood samples were analyzed with CMA at a resolution ranging from 1 Mb to 40 Kb. The imbalance was confirmed by FISH or qPCR. We considered copy number variants (CNVs) causative if the variant was responsible for a known syndrome, encompassed gene/s of known function, occurred de novo or, if inherited, the parent was variably affected, and/or the involved gene/s had been reported in association with ID/ASDs in dedicated databases. 91 CNVs were detected in 77 (22.06%) patients: 5 (6.49%) of those presenting with borderline cognitive impairment, 54 (70.13%) with a variable degree of DD/ID, and 18/77 (23.38%) with ID of variable degree and ASDs. 16/77 (20.8%) patients had two different rearrangements. Deletions exceeded duplications (58 versus 33); 45.05% (41/91) of the detected CNVs were de novo, 45.05% (41/91) inherited, and 9.9% (9/91) unknown. The CNVs caused the phenotype in 57/77 (74%) patients; 12/57 (21.05%) had ASDs/ID, and 45/57 (78.95%) had DD/ID. Our study provides further evidence of the high diagnostic yield of CMA for genetic testing in children with unexplained ID/ASDs who had dysmorphic features. We confirm the value of CMA as the first-tier tool in the assessment of those conditions in the pediatric setting. Copyright © 2013 European Paediatric Neurology Society. Published by Elsevier Ltd.

Silver-Russell Syndrome is both clinically and genetically a heterogeneous syndrome. Among the most important dysmorphic features of this condition are: a triangular shaped face with a small mandible, a prominent frontal eminence, a thin vermilion border with downward-pointing lip corners, clino- and brachydactyly of the 5th fingers as well as body asymmetry. The most well-known genetic mutations in this syndrome are: the 11p15 epimutation (20-60% patients) and the maternal uniparental chromosome 7 disomy present in 7% to 15% of patients. Children with SRS have severely impaired physical growth - intrauterine and after birth. This, together with the aforementioned dysmorphic features, forms the main diagnostic criteria. The study group consisted of 12 children treated with growth hormone, aged 2 to 17 (8.9±4.0 years), therein, all of whom met the phenotype diagnostic criteria by Wollmann and Price. The effects of growth hormone therapy on somatic development of these children are also presented. Height and weight improved as a result of growth hormone treatment, but the effects were significantly worse than in children with IUGR. Children from the study group presented also a smaller an improvement in growth velocity than children from the control group, but the difference was statistically insignificant. Growth hormone therapy accelerates the growth of children with SRS but to a smaller extent than the growth of children born with intrauterine growth retardation without dysmorphic features.

Chromosomal abnormality is a common cause of congenital anomalies, psychiatric disorders, and mental retardation. However, the double trisomy 48,XXX,+18 is a rare chromosome abnormality. Case report and literature review. A 7-hour-old girl presented to our unit because of poor response after birth. She presented with multiple dysmorphic features, including small for gestational age infant, flat nasal bridge, widely-spaced eyes, the left thumb deformities, flat facial profile, raised sternum, ventricular septal defect, the third lateral brain ventricle enlargement, and small liver. This case expands the spectrum of malformations reported in association with the double trisomy 48,XXX,+18. The literature on 16 fetuses or infants with the 48,XXX,+18 were also reviewed. These data suggested that in patients with clinical features similar to trisomy 18, especially with anomalies of the ears and/or reproductive malformations, double trisomy (48,XXX,+18) should be considered and karyotyping should be performed although it is a rare disease.

We report on a girl with partial deletion of Xp and partial duplication of 22q. Family studies demonstrate that both the patient's mother and her nonidentical twin sister carry the corresponding balanced translocation; 46,X,t(X;22)(p11.4;q11.2). This girl has developmental delay, microcephaly, mild dysmorphisms and hearing loss but otherwise shows few of the features described in individuals with duplications of the long arm of chromosome 22. She does manifest characteristics, such as short stature and biochemical evidence of ovarian failure, which are seen in partial or complete Xp deletions and Turner's syndrome.

We report on a 4-year-old boy with a proximal interstitial deletion in the short arm of chromosome 4p with the karyotype 46,XY,del(4)(p14p15.32),inv(9)(p13q13). For a precise delineation of the deleted region, an array-based comparative genomic hybridization (a-CGH) analysis was performed. The proband's phenotype and cytogenetic findings are compared with previously reported cases with proximal 4p deletion syndrome. The syndrome is associated with normal growth, varying degrees of mental retardation, characteristic facial appearance and minor dysmorphic features. Additionally, our patient developed a seizure disorder due to abnormal neuronal migration, i.e., periventricular heterotopia.

This study aimed to generate data for the S1 and S2 alar pedicle and body and the alar orientations for both dysmorphic and normal sacra. The study comprised two groups: Group N consisted of 53 normal sacra and Group D included 10 dysmorphic sacra. Various features such as alar pedicle circumference; anterior, middle, and posterior axis of the sacral ala; sacral body height and width; and sagittal thickness were measured. In group N, the median anterior axis of the alae was observed to be 30° on the right and 25° on the left, the median midline axis was found to be 20° on the right and 15° on the left, and the median posterior alar axis was -15° on the right and -20° on the left. The true S1 and S2 alar pedicle circumferences were observed to be significantly smaller in group D, which demonstrated a shorter S1 alar pedicle mean circumference, significantly narrower S1 body mean width, and considerably tapered sagittal thickness. Our analysis indicated that dysmorphic sacra have a lower sagittal thickness and width of bodies and smaller alar pedicles, which explains the difficulties in their percutaneous fixation.

3-M syndrome: description of six new patients with review of the literature.

2001-10-01

3-M syndrome combines pre- and postnatal growth retardation and dysmorphic facial features with autosomal recessive inheritance. Six new patients with 3-M syndrome are described and compared with 28 cases from the literature. Our six patients have a growth pattern, which parallels that of Silver-Russell syndrome (SRS). Final height is ISD less in 3-M syndrome than in SRS. Growth hormone treatment significantly increased final height in two of our patients. 3-M syndrome can be differentiated from other types of dwarfism by clinical criteria and by the demonstration of characteristically slender long bones and foreshortened vertebral bodies. We propose that calculating the metacarpal and vertebral indices can be used to measure and document this important diagnostic feature. While the gonadal status of female patients with 3-M syndrome is completely normal, male patients have a gonadal dysfunction and sub- or infertility.

The aim of this report was to evaluate and announce the first documented appearance of Horn Kolb syndrome in Turkey. Acheiropodia (Horn Kolb Syndrome) is the bilateral congenital amputation of the distal parts of the 4 extremities. It is an autosomal recessive developmental disorder. The characteristic features are amputation of the upper and lower extremities with aplasia of the hands and feet. The disorder affects only the extremities without other systemic manifestations. In this report, we present the first known case of Horn Kolb syndrome in Turkey, along with the diagnostic features. Severe dysmorphic skeletal anomalies should be excluded as soon as the earlier gestational weeks in every pregnancy by visualizing all 4 limbs of the fetus in routine prenatal ultrasound screening.

We report a three-generation family manifesting a previously undescribed X-linked mental retardation syndrome. Four of the six moderately retarded males have had episodes of manic-depressive psychosis. The phenotype also includes pyramidal signs, Parkinsonian features, and macroorchidism, but there are no characteristic dysmorphic facial features. Affected males do not show fragile sites at distal Xq on cytogenetic analysis, nor do they have expansions of the CGG repeats at the FRAXA, FRAXE, or FRAXF loci. Linkage analyses were undertaken, and a maximal LOD score of 3.311 at theta = .0 was observed with the microsatellite marker DXS1123 in Xq28. A recombination was detected in one of the affected males with DXS1691 (Xq28), which gives the proximal boundary of the localization. No distal recombination has been detected at any of the loci tested. Images Figure 2 PMID:8651288

Studies of epilepsy associated with chromosomal abnormalities may provide information about clinical and EEG phenotypes and possibly to identify new epilepsy genes. We describe a female patient with intractable focal epilepsy, borderline intellectual functioning, and facial dysmorphisms, in whom genetic study (i.e., karyotype and array-CGH analysis) revealed a distal trisomy 4p and distal monosomy Xq. Although any genetic hypothesis remains speculative, several genes are located in the 4p chromosome segment involved in the rearrangement, some of which may be related to epilepsy.

Clinical features of muscle dysmorphia among males with body dysmorphic disorder.

Muscle dysmorphia - a pathological preoccupation with muscularity - appears to be a form of body dysmorphic disorder (BDD) with a focus on muscularity. However, little is known about muscle dysmorphia in men with BDD, and no study has compared men with BDD who do and do not report muscle dysmorphia. To explore this issue, we reviewed the histories of 63 men with BDD; we compared those rated as having a history of muscle dysmorphia with those who had BDD but not muscle dysmorphia in several domains. The 14 men with muscle dysmorphia resembled the 49 comparison men in demographic features, BDD severity, delusionality, and number of non-muscle-related body parts of concern. However, those with muscle dysmorphia were more likely to have attempted suicide, had poorer quality of life, and had a higher frequency of any substance use disorder and anabolic steroid abuse. Thus, muscle dysmorphia was associated with greater psychopathology.

Differences in the presentation of clinical features of body dysmorphic disorder (BDD) across ethnic groups have received little investigation. The current study assessed BDD symptoms in an ethnically diverse sample of adults (n=401) using an online survey. Participants completed self-report measures assessing BDD symptoms, body parts of concern and BDD behaviors. Compared to Caucasian participants, no significant differences were found in body parts or behaviors reported by Latino or African American participants. Significant group differences did emerge between Asian and Caucasian participants. Specifically, Asians reported more concern with straight hair and dark skin and fewer body shape concerns than Caucasians. Asians also endorsed lower rates of grooming, touching body parts, and camouflaging and higher rates of exercise compared to Caucasians. Although most clinical features of BDD appear similar across ethnic groups, results showed some differences in body parts and behaviors between Caucasians and Asian Americans with BDD symptoms.

Current research on pycnodysostosis.

Turan, Serap

2014-08-01

Pycnodysostosis is a rare autosomal recessive disorder caused by an inactivating mutation in cathepsin K (CTSK) and characterized by dysmorphic facial features, a short stature, acroosteolysis, osteosclerosis with increased bone fragility, and delayed closure of cranial sutures. Patients usually present with short stature or dysmorphic features the Pediatric Endocrinology or Genetics clinics, with atypical fractures to the orthopedics clinics or hematological abnormalities to the hematology clinics. However, under-diagnosis or misdiagnosis of this condition is a major issue. Pycnodysostosis is not a life threatening condition, but craniosynostosis, frequent fractures, respiratory-sleep problems, and dental problems may cause significant morbidity. Although no specific treatment for this disorder has been described, patients should be followed for complications and treated accordingly. A specific treatment for the disorder must be established in the future to prevent complications and improve quality of life for patients in the current era of advanced molecular research.

The deletion of the chromosome 4p16.3 Wolf-Hirschhorn syndrome critical region (WHSCR-2) typically results in a characteristic facial appearance, varying intellectual disability, stereotypies and prenatal onset of growth retardation, while gains of the same chromosomal region result in a more variable degree of intellectual deficit and dysmorphism. Similarly the phenotype of individuals with terminal deletions of distal chromosome 3p (3p deletion syndrome) varies from mild to severe intellectual deficit, micro- and trigonocephaly, and a distinct facial appearance. We investigated a large Indian five-generation pedigree with ten affected family members in which chromosomal microarray and fluorescence in situ hybridization analyses disclosed a complex rearrangement involving chromosomal subregions 4p16.1 and 3p26.3 resulting in a 4p16.1 deletion and 3p26.3 microduplication in three individuals, and a 4p16.1 duplication and 3p26.3 microdeletion in seven individuals. A typical clinical presentation of WHS was observed in all three cases with 4p16.1 deletion and 3p26.3 microduplication. Individuals with a 4p16.1 duplication and 3p26.3 microdeletion demonstrated a range of clinical features including typical 3p microdeletion or 4p partial trisomy syndrome to more severe neurodevelopmental delay with distinct dysmorphic features. We present the largest pedigree with complex t(4p;3p) chromosomal rearrangements and diverse clinical outcomes including Wolf Hirschorn-, 3p deletion-, and 4p duplication syndrome amongst affected individuals.

Association of a Novel Nonsense Mutation in KIAA1279 with Goldberg-Shprintzen Syndrome.

2017-01-01

Goldberg-Shprintzen syndrome (OMIM 609460) (GOSHS) is an autosomal recessive multiple congenital anomaly syndrome distinguished by intellectual disability, microcephaly, and dysmorphic facial characteristics. Most affected individuals also have Hirschsprung disease and/or gyral abnormalities of the brain. This syndrome has been associated with KIAA1279 gene mutations at 10q22.1. Here we report a 16 yr old male patient referred to Center for Comprehensive Genetic Services, Tehran, Iran in 2015 with cardinal features of GOSHS in addition to refractory seizures. Whole exome sequencing in the patient revealed a novel nonsense (stop gain) homozygous mutation in KIAA1279 gene (KIAA1279: NM_015634:exon6:c.C976T:p.Q326X). Considering the wide range of phenotypic variations in GOSHS, relying on phenotypic characteristics for discrimination of GOSH from similar syndromes may lead to misdiagnosis. Consequently, molecular diagnostic tools would help in accurate diagnosis of such overlapping phenotypes.

Classical Ehlers-Danlos syndrome (cEDS) is characterized by marked cutaneous involvement, according to the Villefranche nosology and its 2017 revision. However, the diagnostic flow-chart that prompts molecular testing is still based on experts' opinion rather than systematic published data. Here we report on 62 molecularly characterized cEDS patients with focus on skin, mucosal, facial, and articular manifestations. The major and minor Villefranche criteria, additional 11 mucocutaneous signs and 15 facial dysmorphic traits were ascertained and feature rates compared by sex and age. In our cohort, we did not observe any mandatory clinical sign. Skin hyperextensibility plus atrophic scars was the most frequent combination, whereas generalized joint hypermobility according to the Beighton score decreased with age. Skin was more commonly hyperextensible on elbows, neck, and knees. The sites more frequently affected by abnormal atrophic scarring were knees, face (especially forehead), pretibial area, and elbows. Facial dysmorphism commonly affected midface/orbital areas with epicanthal folds and infraorbital creases more commonly observed in young patients. Our findings suggest that the combination of ≥1 eye dysmorphism and facial/forehead scars may support the diagnosis in children. Minor acquired traits, such as molluscoid pseudotumors, subcutaneous spheroids, and signs of premature skin aging are equally useful in adults. © 2017 John Wiley & Sons A/S.

This study was conducted to determine the prevalence of chromosomal anomalies in newborns with structural heart disease admitted to the cardiac intensive care unit (CICU) at Nicklaus Children's Hospital (NCH). A retrospective review identified newborns age 30 days or less admitted to NCH CICU between 2004 and 2010. Patients with structural heart disease who required admission to our CICU and received karyotype or karyotype and fluorescent in situ hybridization (FISH) testing were included in the study. All patients were examined for the presence of dysmorphic features. Four hundred and eighty-two patients met the criteria for the study; 405 (84%) received both karyotype and FISH. Chromosome abnormalities were present in 86 (17.8%) patients. Syndromes accounted for 20 (5.1%) of those with normal chromosomes. Dysmorphic features were seen in 79.1% of patients with abnormal chromosomes and 25.5% of those with normal chromosomes. All patients with syndromes were dysmorphic. Race and gender did not significantly affect the incidence of genetic abnormalities. Chromosome abnormalities, including syndromes, are prevalent in newborns with congenital heart disease. Further research is needed to evaluate the utility of cytogenetic screening in all children with congenital heart disease. Published by the BMJ Publishing Group Limited.

2018-03-01

We describe a case of a six-year-old girl who presents multiple dysmorphic features characteristic of Down's syndrome. She has a significant general developmental delay, with a score that correspond to 32 months of developmental age. This delay is especially in language, with a very scant vocabulary. She communicates with some hand sign words or pointing, although her auditory responses in hearing test were normal. Two previous karyotype studies showed 47, XXX, +21 anomalies. This double trisomy is a rare condition described in isolated cases in the literature and none of these refers to the developmental aspects of these children (Balwan et al. 2008; Li et al. 2004; Park et al. 1995; Day et al. 1963).

Dentinogenesis imperfecta associated with short stature, hearing loss and mental retardation: a new syndrome with autosomal recessive inheritance?

PubMed

2005-08-01

The follow-up history and oral findings in two brothers from consanguineous parents suggest that the association of dentinogenesis imperfecta (DI), delayed tooth eruption, mild mental retardation, proportionate short stature, sensorineural hearing loss and dysmorphic facies may represent a new syndrome with autosomal recessive inheritance. Histological examination of the dentin matrix of a permanent molar from one of the siblings reveals morphological similarities with defective dentinogenesis as presenting in patients affected with Osteogenesis Imperfecta (OI), a condition caused by deficiency of type I collagen. A number of radiographic and histological characteristics, however, are inconsistent with classical features of DI. These findings suggest that DI may imply greater genetical heterogeneity than currently assumed.

A previous report described a unique phenotype associated with an apparently de novo 732 kb 19q13.32 microdeletion, consisting of intellectual disability, facial asymmetry, ptosis, oculomotor abnormalities, orofacial clefts, cardiac defects, scoliosis and chronic constipation. We report three unrelated patients with developmental delay and dysmorphic features, who were all found to have interstitial 19q13.32 microdeletions of varying sizes. Both the previously reported patient and our Patient 1 with a larger, 1.3-Mb deletion have distinctive dysmorphic features and medical problems, allowing us to define a recognizable 19q13.32 microdeletion syndrome. Patient 1 was hypotonic and dysmorphic at birth, with aplasia of the posterior corpus callosum, bilateral ptosis, oculomotor paralysis, down-slanting palpebral fissures, facial asymmetry, submucosal cleft palate, micrognathia, wide-spaced nipples, right-sided aortic arch, hypospadias, bilateral inguinal hernias, double toenail of the left second toe, partial 2-3 toe syndactyly, kyphoscoliosis and colonic atony. Therefore, the common features of the 19q13.32 microdeletion syndrome include facial asymmetry, ptosis, oculomotor paralysis, orofacial clefting, micrognathia, kyphoscoliosis, aortic defects and colonic atony. These findings are probably related to a deletion of some combination of the 20-23 genes in common between these two patients, especially NPAS1, NAPA, ARHGAP35, SLC8A2, DHX34, MEIS3, and ZNF541. These candidate genes are expressed in the brain parenchyma, glia, heart, gastrointestinal tract and musculoskeletal system and likely play a fundamental role in the expression of this phenotype. This report delineates the phenotypic spectrum associated with the haploinsufficiency of genes found in 19q13.32. Copyright © 2014 Elsevier Masson SAS. All rights reserved.

Body Dysmorphic Symptoms, Functional Impairment, and Depression: The Role of Appearance-Based Teasing.

PubMed

Weingarden, Hilary; Renshaw, Keith D

2016-01-01

Body dysmorphic disorder is associated with elevated social and occupational impairment and comorbid depression, but research on risk factors for body dysmorphic symptoms and associated outcomes is limited. Appearance-based teasing may be a potential risk factor. To examine the specificity of this factor, the authors assessed self-reported appearance-based teasing, body dysmorphic, and obsessive-compulsive symptom severity, functional impairment (i.e., social, occupational, family impairment), and depression in a nonclinical sample of undergraduates. As hypothesized, appearance-based teasing was positively correlated with body dysmorphic symptoms. The correlation between teasing and body dysmorphic symptoms was stronger than that between teasing and obsessive-compulsive symptom severity. Last, body dysmorphic symptom severity and appearance-based teasing interacted in predicting functional impairment and depression. Specifically, appearance-based teasing was positively associated with depression and functional impairment only in those with elevated body dysmorphic symptoms. When a similar moderation was tested with obsessive-compulsive, in place of body dysmorphic, symptom severity, the interaction was nonsignificant. Findings support theory that appearance-based teasing is a specific risk factor for body dysmorphic symptoms and associated functional impairment.

2016-06-01

The Body Dysmorphic Disorder Symptom Scale (BDD-SS) is a new self-report measure used to examine the severity of a wide variety of symptoms associated with body dysmorphic disorder (BDD). The BDD-SS was designed to differentiate, for each group of symptoms, the number of symptoms endorsed and their severity. This report evaluates and compares the psychometric characteristics of the BDD-SS in relation to other measures of BDD, body image, and depression in 99 adult participants diagnosed with BDD. Total scores of the BDD-SS showed good reliability and convergent validity and moderate discriminant validity. Analyses of the individual BDD-SS symptom groups confirmed the reliability of the checking, grooming, weight/shape, and cognition groups. The current findings indicate that the BDD-SS can be quickly administered and used to examine the severity of heterogeneous BDD symptoms for research and clinical purposes. Copyright © 2016.

Cognitive-Behavioral Therapy for Youth with Body Dysmorphic Disorder: Current Status and Future Directions

PubMed Central

Phillips, Katharine A.; Rogers, Jamison

2011-01-01

SYNOPSIS Body dysmorphic disorder (BDD), a distressing or impairing preoccupation with nonexistent or slight defect(s) in appearance, usually begins during early adolescence and appears to be common in youth. BDD is characterized by substantial impairment in psychosocial functioning and markedly high rates of suicidality. Cognitive-behavioral therapy (CBT) tailored to BDD’s unique features is the best tested and most promising psychosocial treatment for adults with BDD. CBT has been used for youth with BDD, but it has not been systematically developed for or tested in this age group, and there is a pressing need for this work to be done. This article focuses on CBT for BDD in adults and youth, possible adaptations for youth, and the need for treatment research in youth. We also discuss BDD’s prevalence, clinical features, how to diagnose BDD in youth, recommended pharmacotherapy for BDD (serotonin-reuptake inhibitors), and treatments that are not recommended (surgery and other cosmetic treatments).

A Review of Body Dysmorphic Disorder and Its Presentation in Different Clinical Settings

Mufaddel, Amir; Osman, Ossama T.; Almugaddam, Fadwa

2013-01-01

Objective: Body dysmorphic disorder (BDD) is a relatively common psychiatric disorder characterized by preoccupations with perceived defects in physical appearance. This review aimed to explore epidemiology, clinical features, comorbidities, and treatment options for BDD in different clinical settings. Data Source and Study Selection: A search of the literature from 1970 to 2011 was performed using the MEDLINE search engine. English-language articles, with no restriction regarding the type of articles, were identified using the search terms body dysmorphic disorder, body dysmorphic disorder clinical settings, body dysmorphic disorder treatment, and body dysmorphic disorder & psychodermatology. Results: BDD occurs in 0.7% to 2.4% of community samples and 13% of psychiatric inpatients. Etiology is multifactorial, with recent findings indicating deficits in visual information processing. There is considerable overlap between BDD and obsessive-compulsive disorder (OCD) in symptom etiology and response to treatment, which has led to suggestions that BDD can be classified with anxiety disorders and OCD. A recent finding indicated genetic overlap between BDD and OCD. Over 60% of patients with BDD had a lifetime anxiety disorder, and 38% had social phobia, which tends to predate the onset of BDD. Studies reported a high level of comorbidity with depression and social phobia occurring in > 70% of patients with BDD. Individuals with BDD present frequently to dermatologists (about 9%–14% of dermatologic patients have BDD). BDD co-occurs with pathological skin picking in 26%–45% of cases. BDD currently has 2 variants: delusional and nondelusional, and both variants respond similarly to serotonin reuptake inhibitors (SRIs), which may have effect on obsessive thoughts and rituals. Cognitive-behavioral therapy has the best established treatment results. Conclusions: A considerable overlap exists between BDD and other psychiatric disorders such as OCD, anxiety, and delusional disorder, and this comorbidity should be considered in evaluation, management, and long-term follow-up of the disorder. Individuals with BDD usually consult dermatologists and cosmetic surgeons rather than psychiatrists. Collaboration between different specialties (such as primary care, dermatology, cosmetic surgery, and psychiatry) is required for better treatment outcome. PMID:24392251

The Waardenburg syndromes (WS) account for approximately 2% of congenital sensorineural deafness. This heterogeneous group of diseases currently can be categorized into four major subtypes (WS types 1-4) on the basis of characteristic clinical features. Multiple genes have been implicated in WS, and mutations in some genes can cause more than one WS subtype. In addition to eye, hair and skin pigmentary abnormalities, dystopia canthorum and broad nasal bridge are seen in WS type 1. Mutations in the PAX3 gene are responsible for the condition in the majority of these patients. In addition, mutations in PAX3 have been found in WS type 3 that is distinguished by musculoskeletal abnormalities, and in a family with a rare subtype of WS, craniofacial-deafness-hand syndrome (CDHS), characterized by dysmorphic facial features, hand abnormalities, and absent or hypoplastic nasal and wrist bones. Here we describe a woman who shares some, but not all features of WS type 3 and CDHS, and who also has abnormal cranial bones. All sinuses were hypoplastic, and the cochlea were small. No sequence alteration in PAX3 was found. These observations broaden the clinical range of WS and suggest there may be genetic heterogeneity even within the CDHS subtype. PMID:18553554

We present an 18-month-old Pakistani girl who had short stature, craniofacial dysmorphism, and multiple café-au-lait spots. After consultation with the geneticists, microcephalic osteodysplastic primordial dwarfism type II was diagnosed (MIM210720). The presence of consanguinity in reported families is suggestive of autosomal recessive inheritance.

Haploinsufficiency of the insulin-like growth factor-1 receptor (IGF1R) gene on chromosome 15q26.3 is associated with impaired prenatal and postnatal growth, developmental delay, dysmorphic features and skeletal abnormalities. Terminal deletions of chromosome 15q26 arising more proximally may also be associated with congenital heart disease, epilepsy, diaphragmatic hernia and renal anomalies. We report three additional cases of 15q26 terminal deletions with novel features which may further expand the spectrum of this rarely reported contiguous gene syndrome. Phenotypic features including neonatal lymphedema, aplasia cutis congenita and aortic root dilatation have not been reported previously. Similarly, laboratory features of insulin-like growth factor 1 (IGF-1) resistance are described, including markedly elevated IGF-1 of up to +4.7 SDS. In one patient, the elevated IGF-1 declined over time and this coincided with a period of spontaneous growth acceleration. Deletions of 15q26 are a potential risk factor for aortic root dilatation, neonatal lymphedema and aplasia cutis in addition to causing growth restriction. What is Known: • Terminal deletions of chromosome 15q26 are associated with impaired prenatal and postnatal growth, developmental delay, dysmorphic features and skeletal abnormalities. What is New: • Neonatal lymphedema, aplasia cutis congenita and aortic root dilatation have not been previously described in 15q26 terminal deletions and may represent novel features. • IGF-1 levels may be increased up to 4.7 SDS.

Noonan syndrome is part of the group of RASopathies caused by germ line mutations in genes involved in the RAS/MAPK pathway. There is substantial phenotypic overlap among the RASopathies. Diagnosis of Noonan syndrome is often based on clinical features including dysmorphic facial features, short stature and congenital heart disease. Rapid advances in sequencing technology have made molecular genetic analyses a helpful tool in diagnosing and distinguishing Noonan syndrome from other RASopathies.

The relationship between perceived social support and severity of body dysmorphic disorder symptoms: the role of gender.

PubMed

Marques, Luana; Weingarden, Hilary M; LeBlanc, Nicole J; Siev, Jedidiah; Wilhelm, Sabine

2011-09-01

Whether social support is associated with severity of body dysmorphic symptoms is unknown. To address this gap in the literature, the present study aims to examine the association between three domains of perceived social support (i.e., family, friends, and significant others) and severity of body dysmorphic disorder symptoms. Participants (N = 400) with symptoms consistent with diagnosis of body dysmorphic disorder completed measures of symptomatology and social support via the internet. More perceived social support from friends and significant others was associated with less severe body dysmorphic disorder symptoms for males, and more perceived social support from family and friends was associated with less severe body dysmorphic disorder symptoms among females. Additionally, gender moderated the association between perceived social support from significant others and symptom severity, such that perceived social support from a significant other was significantly negatively associated with body dysmorphic symptom severity in males, but not females. The present study implicates social support as an important area of future body dysmorphic disorder research.

Psychological treatment of social anxiety disorder improves body dysmorphic concerns.

Fang, Angela; Sawyer, Alice T; Aderka, Idan M; Hofmann, Stefan G

2013-10-01

Social anxiety disorder and body dysmorphic disorder are considered nosologically distinct disorders. In contrast, some cognitive models suggest that social anxiety disorder and body dysmorphic disorder share similar cognitive maintenance factors. The aim of this study was to examine the effects of psychological treatments for social anxiety disorder on body dysmorphic disorder concerns. In Study 1, we found that 12 weekly group sessions of cognitive-behavioral therapy led to significant decreases in body dysmorphic symptom severity. In Study 2, we found that an attention retraining intervention for social anxiety disorder was associated with a reduction in body dysmorphic concerns, compared to a placebo control condition. These findings support the notion that psychological treatments for individuals with primary social anxiety disorder improve co-occurring body dysmorphic disorder symptoms.

Monozygotic twins, developed from a single zygote, are almost identical in clinical phenotype and concordant karyotypes. Monozygotic twins with discordant karyotypes are thought to be quite rare. Here, we report monochorionic-diamniotic twins discordant for Down syndrome. On findings of prenatal ultrasonography, nuchal translucency thickness was different between twins, and suggested that one of the twins was at high risk for having chromosomal abnormalities including Down syndrome. The twins were monochorionic-diamniotic; therefore, chorionic villi sampling of the common placenta was performed. The karyotype of the chorionic villi cells was 46,XX, and pregnancy was maintained. After delivery, dysmorphic clinical features suggesting Down syndrome were found in one of the twins, while the other twin showed a morphologically normal appearance. Karyotypes of peripheral blood leukocytes were repeatedly normal in the dysmorphic twin; however, the karyotype of skin fibroblasts from the dysmorphic twin indicated Down syndrome mosaicism; 47,XX,+21[99]/46,XX[2]. The karyotype of skin fibroblasts from the morphologically normal twin was 46,XX. Monozygosity of the twins was confirmed by a short tandem repeat analysis using 16 polymorphic markers. A mitotic nondisjunction followed by the twinning would explain the discordant karyotypes between monozygotic twins.

Hypertelorism in Charcot-Marie-Tooth disease 1A from the common PMP22 duplication: A Case Report

PubMed Central

Finsterer, Josef

2012-01-01

The 1.4Mb tandem-duplication in the PMP22 gene at 17p11.2 usually manifests as hereditary sensorimotor polyneuropathy with foot deformity, sensorineural hearing-loss, moderate developmental delay, and gait disturbance. Hypertelorism and marked phenotypic variability within a single family has not been reported. In a single family, the PMP22 tandem-duplication manifested as short stature, sensorimotor polyneuropathy, tremor, ataxia, sensorineural hearing-loss, and hypothyroidism in the 27 years-old index case, as mild facial dysmorphism, muscle cramps, tinnitus, intention tremor, bradydiadochokinesia, and sensorimotor polyneuropathy in the 31 year-old half-brother of the index-patient, and as sensorimotor polyneuropathy and foot-deformity in the father of the two. The half-brother additionally presented with hypertelorism, not previously reported in PMP22 tandem-duplication carriers. The presented cases show that the tandem-duplication 17p11.2 may present with marked intra-familial phenotype variability and that mild facial dysmorphism with stuck-out ears and hypertelorism may be a rare phenotypic feature of this mutation. The causal relation between facial dysmorphism and the PMP22 tandem-duplication, however, remains speculative. PMID:22496945

Body Dysmorphic Disorder: Neurobiological Features and an Updated Model

Li, Wei; Arienzo, Donatello; Feusner, Jamie D.

2013-01-01

Body Dysmorphic Disorder (BDD) affects approximately 2% of the population and involves misperceived defects of appearance along with obsessive preoccupation and compulsive behaviors. There is evidence of neurobiological abnormalities associated with symptoms in BDD, although research to date is still limited. This review covers the latest neuropsychological, genetic, neurochemical, psychophysical, and neuroimaging studies and synthesizes these findings into an updated (yet still preliminary) neurobiological model of the pathophysiology of BDD. We propose a model in which visual perceptual abnormalities, along with frontostriatal and limbic system dysfunction, may combine to contribute to the symptoms of impaired insight and obsessive thoughts and compulsive behaviors expressed in BDD. Further research is necessary to gain a greater understanding of the etiological formation of BDD symptoms and their evolution over time. PMID:25419211

2016-09-01

This study examined the bidirectional (conjoint) longitudinal pathways linking adolescents' body dysmorphic disorder (BDD) symptoms with self- and peer-reported social functioning. Participants were 367 Australian students (45.5% boys, mean age=12.01 years) who participated in two waves of a longitudinal study with a 12-month lag between assessments. Participants self-reported their symptoms characteristic of BDD, and perception of peer acceptance. Classmates reported who was popular and victimized in their grade, and rated their liking (acceptance) of their classmates. In support of both stress exposure and stress generation models, T1 victimization was significantly associated with more symptoms characteristic of BDD at T2 relative to T1, and higher symptom level at T1 was associated with lower perceptions of peer acceptance at T2 relative to T1. These results support the hypothesized bidirectional model, whereby adverse social experiences negatively impact symptoms characteristic of BDD over time, and symptoms also exacerbate low perceptions of peer-acceptance.

A Case of Treatment- resistant Depression and Body Dysmorphic Disorder: The Role of Electroconvulsive Therapy Revisited.

PubMed

Mahato, Ram S; San Gabriel, Maria Chona P; Longshore, Carrol T; Schnur, David B

2016-01-01

Body dysmorphic disorder is a common, often disabling condition, and is frequently comorbid with major depressive disorder. Selective serotonin reuptake inhibitors constitute first line set of somatic interventions but the management of refractory patients remains challenging. Electroconvulsive therapy, an often highly beneficial treatment for medication resistant-depression, is not considered an effective therapeutic alternative for treatment refractory body dysmorphic disorder. Here we present a 50-year-old woman with body dysmorphic disorder and comorbid major depressive disorder who remained incapacitated and suicidal despite several trials with selective serotonin reuptake inhibitors and antipsychotic medication. Depressive and dysmorphic symptoms appeared to resolve with electroconvulsive therapy, and remission was sustained for two months. Electroconvulsive therapy has an important place in the management of treatment- resistant depression associated with body dysmorphic disorder, and, in select cases, may be effective for dysmorphic symptoms as well.

Body dysmorphic disorder may negatively affect self-perception of body shape and lead patients to seek cosmetic surgery. This study estimates the level of body dissatisfaction and prevalence of body dysmorphic disorder symptoms in candidates for three plastic surgical procedures. Three hundred patients of both sexes divided into three groups (abdominoplasty, n = 90; rhinoplasty, n =151; and rhytidectomy, n =59) were classified as having (n =51, n =79, and n =25, respectively) or not having (n =39, n =72, and n =34, respectively) body dysmorphic disorder symptoms, based on the Body Dysmorphic Disorder Examination, which was administered preoperatively. Prevalence rates of body dysmorphic disorder symptoms in the abdominoplasty, rhinoplasty, and rhytidectomy groups were 57, 52, and 42 percent, respectively. Significant between-group differences were observed regarding age (p < 0.001), body mass index (p = 0.001), and onset of body dysmorphic disorder symptoms (p < 0.001). Within-group differences in body dysmorphic disorder severity were observed in the abdominoplasty (p < 0.001), rhinoplasty (p < 0.001), and rhytidectomy (p = 0.005) groups. Body dysmorphic disorder severity was significantly associated with degree of body dissatisfaction (mean Body Dysmorphic Disorder Examination total scores; p < 0.001), avoidance behaviors (p< 0.001), sexual abuse (p = 0.026), suicidal ideation (p < 0.001), and suicide attempt (p = 0.012). Abdominoplasty candidates showed the highest prevalence; rhytidectomy candidates exhibited the highest percentage of severe cases, and rhinoplasty candidates had the lowest percentage of severe cases.

Schinzel-Giedion syndrome (SGS) (#MIM 269150) is a rare genetic disorder characterized by very marked craniofacial dysmorphism, multiple congenital anomalies and severe intellectual disability. Most affected patients die in early childhood. SETBP1 was identified as the causative gene, but a limited number of patients with molecular confirmation have been reported to date. The case is reported of a 4 and a half year-old male patient, affected by SGS. SETBP1 sequencing analysis revealed the presence of a non-previously described mutation: c.2608G>T (p.Gly870Cys). The clinical features and differential diagnosis of this rare condition are reviewed. Dysmorphic features are strongly suggestive of SGS. Its clinical recognition is essential to enable an early diagnosis, a proper follow-up, and to provide the family with genetic counseling. To date, this is the seventeenth SGS patient published with SETBP1 mutation, and the first in Spain, helping to widen clinical and molecular knowledge of the disease.

Dysmorphic neurons and balloon cells constitute the neuropathological hallmarks of type II focal cortical dysplasias (FCDs) with refractory epilepsy. The genesis of these cells may be critical to the histological findings in type II FCD. Recent work has shown enhanced activation of the mTOR cascade in both balloon cells and dysmorphic neurons, suggesting a common pathogenesis for these two neuropathological hallmarks. A direct comparative analysis of balloon cells and dysmorphic neurons might identify a molecular link between balloon cells and dysmorphic neurons. Here, we addressed whether PDK1-AKT-mTOR activation differentiates balloon cells from dysmorphic neurons. We used immunohistochemistry with antibodies against phosphorylated (p)-PDK1 (Ser241), p-AKT (Thr308), p-AKT (Ser473), p-mTOR (Ser2448), p-P70S6K (Thr229), and p-p70S6 kinase (Thr389) in balloon cells compared with dysmorphic neurons. Strong or moderate staining for components of the PDK1-AKT-mTOR signaling pathway was observed in both balloon cells and dysmorphic neurons. However, only a few pyramidal neurons displayed weak staining in control group (perilesional neocortex and histologically normal neocortex). Additionally, p-PDK1 (Ser241) and p-AKT (Thr308) staining in balloon cells were stronger than in dysmorphic neurons, whereas p-P70S6K (Thr229) and p-p70S6 kinase (Thr389) staining in balloon cells was weaker than in dysmorphic neurons. In balloon cells, p-AKT (Ser473) and p-mTOR (Ser2448) staining was comparable with the staining in dysmorphic neurons. Our data support the previously suggested pathogenic relationship between balloon cells and dysmorphic neurons concerning activation of the PDK1-AKT-mTOR, which may play important roles in the pathogenesis of type II FCD. Differential expression of some components of the PDK1-AKT-mTOR pathway between balloon cells and dysmorphic neurons may result from cell-specific gene expression. Copyright © 2015 Elsevier B.V.

A trisomy of the distal long arm of chromosome 15(q21 leads to qter) resulting in similar phenotypic and developmental abnormalities in two related children (a boy and a girl) is described. The chromosome defect was due to malsegregation of a balanced translocation (5;15)(p14;q21) in one of the parents. It was inherited in four generations and accompanied by recurrent miscarriages. Comparison of these patients with four previously published cases of trisomy 15q dist reveals a pattern of common features including: microdolichocephaly with characteristic strikingly protuberant occiput and predominance of the visceral over the cerebral cranium; peculiar facial dysmorphism--narrow antimongoloid palpebral fissures; large, malformed, low-set ears; micrognathy; long philtrum; short neck; cardiopathy; profound encephalopathy with lack of suck and swallow reflexes; and no growth retardation.

The cardinal features of Primrose syndrome (MIM 259050) are dysmorphic facial features, macrocephaly, and intellectual disability, as well as large body size, height and weight, and calcified pinnae. A variety of neurological signs and symptoms have been reported including hearing loss, autism, behavioral abormalities, hypotonia, cerebral calcifications, and hypoplasia of the corpus callosum. Recently, heterozygous de novo missense mutations in ZBTB20, coding for a zing finger protein, have been identified in Primrose syndrome patients. We report a boy with intellectual disability carrying two de novo missense mutations in the last exon of ZBTB20 (Ser616Phe and Gly741Arg; both previously unreported). One of them, Ser616Phe, affects an amino acid located in one of the C2H2 zing-fingers involved in DNA-binding and close to other missense mutations already described. Reverse phenotyping showed that this patient presents with classic features of Primrose syndrome (dysmorphic facies, macrocephaly, hearing loss, hypotonia, hypoplasia of the corpus callosum) and, in addition, congenital hypothyroidism. Review of the literature reveals another Primrose syndrome patient with hypothyroidism and thus, this may represent an under recognized component that should be investigated in other patients. © 2016 Wiley Periodicals, Inc. © 2016 Wiley Periodicals, Inc.

Body dysmorphic disorder (BDD) is a relatively common disorder with a point prevalence of 0.7-2.4 %. BDD is characterized by the patient's excessive concern with an imagined or slight defect in physical appearance. BDD usually begins in adolescence. Comorbidity rates and also suicidality rates are high. The course of BDD tends to be chronic. According to the present state of knowledge, cognitive-behavioral therapy and pharmacotherapy with selective serotonin reuptake inhibitors are valuable options in the therapy of BDD. The case report describes a recent case of BDD with typical clinical and therapy-related characteristics. The aim of this work is to strengthen the awareness of BDD in clinical practice of child and adolescent psychiatry, facilitating an adequate diagnosis and treatment of the affected individuals.

The Miller-McKusick-Malvaux (3M) syndrome is a rare autosomal disorder that can lead to short stature, dysmorphic features, and skeletal abnormalities with normal intelligence. A 16-month-old female patient had been referred to our clinic due to short stature. Case history revealed a birth weight of 1740 grams on the 39 th week of gestation, with a birth length of 42 cm and no prior hereditary conditions of clinical significance in her family. On physical examination, her length was 67 cm [-3.6 standard deviation (SD) score], weight 7.2 kg (-2.9 SD score), and head circumference 42 cm (below 3 rd percentile). She also had numerous characteristic physical features such as a triangular face, fleshy nose tip, a long philtrum, prominent mouth and lips, pointed chin, lumbar lordosis, and prominent heels. As her growth retardation had a prenatal onset and the physical examination results were suggestive of a characteristic profile, the diagnosis of 3M syndrome was strongly considered. Genetic assessment of the patient revealed a novel homozygous p.T45Nfs*40 mutation in the OBSL1 gene. It is recommended that physicians pay further attention to this condition in the differential diagnosis of children with severe short stature.

New perspectives in the treatment of body dysmorphic disorder

2018-01-01

Body dysmorphic disorder (BDD) is a disabling illness with a high worldwide prevalence. Patients demonstrate a debilitating preoccupation with one or more perceived defects, often marked by poor insight or delusional convictions. Multiple studies have suggested that selective serotonin reuptake inhibitors and various cognitive behavioral therapy modalities are effective first-line treatments in decreasing BDD severity, relieving depressive symptoms, restoring insight, and increasing quality of life. Selective serotonin reuptake inhibitors have also recently been shown to be effective for relapse prevention. This review provides a comprehensive summary of the current understanding of BDD, including its clinical features, epidemiology, genetics, and current treatment modalities. Additional research is needed to fully elucidate the relationship between BDD and comorbid illnesses such as obsessive–compulsive-related disorders and depression and to develop therapies for refractory patients and those who have contraindications for pharmacological intervention.

Abstract Objectives. To examine the accounts of people with body dysmorphic disorder (BDD) and qualitatively explore self perceptions. Methods. Eleven people with BDD were interviewed using a semi-structured schedule. Participants brought photographs of themselves and drew a self-portrait. Transcribed interviews were analysed using a thematic analysis. Results. The most common theme was increased threat perception resulting in disordered interpersonal relationships. Other themes included the wish for regularity and symmetry in appearance, an idealised childhood self, the duty to look good, and a focus on specific "defective" features rather than general ugliness. Conclusions. Using thematic analysis and visual methods, we identified core themes that appear to characterise the way individuals with BDD perceive themselves and their interpersonal relationships. Thematic analysis offers promise as a tool to explore the overlap between BDD and other putatively related mental health problems.

22q11.2 microduplication syndrome is characterized by a large phenotypic variability including facial dysmorphism, developmental delay, and hearing loss. We describe a family in whom 5 of 11 children were affected by a unilateral or bilateral congenital aural atresia. Four of these 5 carried a 22q11.2 microduplication and had typical dysmorphic features. Computed tomography with 3-D reconstructions allowed for a detailed examination of the middle ear structures and classification of the atresia type. Audiometry revealed a moderately severe conductive hearing loss in accordance with the clinical and computed tomography findings. Detailed examination of the ear is warranted in patients with a 22q11.2 microduplication. When outer ear abnormalities are encountered, an additional workup including audiometry and computed tomography with 3-D reconstructions is required.

Sensorineural deafness, distinctive facial features, and abnormal cranial bones: a new variant of Waardenburg syndrome?

2008-07-15

The Waardenburg syndromes (WS) account for approximately 2% of congenital sensorineural deafness. This heterogeneous group of diseases currently can be categorized into four major subtypes (WS types 1-4) on the basis of characteristic clinical features. Multiple genes have been implicated in WS, and mutations in some genes can cause more than one WS subtype. In addition to eye, hair, and skin pigmentary abnormalities, dystopia canthorum and broad nasal bridge are seen in WS type 1. Mutations in the PAX3 gene are responsible for the condition in the majority of these patients. In addition, mutations in PAX3 have been found in WS type 3 that is distinguished by musculoskeletal abnormalities, and in a family with a rare subtype of WS, craniofacial-deafness-hand syndrome (CDHS), characterized by dysmorphic facial features, hand abnormalities, and absent or hypoplastic nasal and wrist bones. Here we describe a woman who shares some, but not all features of WS type 3 and CDHS, and who also has abnormal cranial bones. All sinuses were hypoplastic, and the cochlea were small. No sequence alteration in PAX3 was found. These observations broaden the clinical range of WS and suggest there may be genetic heterogeneity even within the CDHS subtype. 2008 Wiley-Liss, Inc.

Nine children with primordial dwarfism are described and a new syndrome is delineated. The significant features of this syndrome include facial dysmorphism with gloomy face and very short stature, but no radiological abnormality or hormone deficiency. Mental development is normal. The mode of inheritance seems to be autosomal recessive because of consanguinity in three of the four sibships. Some overlap with the 3-M syndrome is discussed but the autonomy of the gloomy face syndrome seems to be real. Images PMID:2051454

The isolated haploinsufficiency of the SHOX gene is one of the most common cause of short stature determined by monogenic mutations. The heterozygous deviation of the gene can be detected in 2-15% of patients with idiopathic short stature (ISS), in 50-90% of patients with Leri-Weill dyschondrosteosis syndrome (LWS), and in almost 100% of patients with Turner syndrome. The aim of our study was to evaluate the frequency of SHOX gene haploinsufficiency in children with ISS, LWS and in patients having Turner syndrome phenotype (TF), but normal karyotype, and to identify the dysmorphic signs characteristic for SHOX gene deficiency. A total of 144 patients were included in the study. Multiplex Ligation-dependent Probe Amplification (MLPA) method was used to identify the SHOX gene haploinsufficiency. The relationships between clinical data (axiological parameters, skeletal disorders, dysmorphic signs) and genotype were analyzed by statistical methods. 11 (7.6%) of the 144 patients showed SHOX gene deficiency with female dominance (8/11, 81% female). The SHOX positive patients had a significantly higher BMI (in 5/11 vs. 20/133 cases, p<0.02) and presented more frequent dysmorphic signs (9/11vs 62/133, p = 0.02). Madelung deformity of the upper limbs was also significantly more frequent among the SHOX positive patients (4/11, i.e. 36%, vs. 14/133, i.e. 10%, p = 0.0066). There were no statistically significant differences between the mean age, mean height and auxological measurements (sitting height/height, arm span/height) between the two groups of patients. The occurrence of SHOX gene haploinsufficiency observed in our population corresponds to the literature data. In SHOX positive patients, in addition to short stature, the dysmorphic signs have a positive predictive value for SHOX gene alterations. However, the SHOX deletion detected in a patient with idiopathic short stature without dysmorphic signs suggest that SHOX deletion analysis can be recommended in patients with ISS.

Prospective investigation of autism and genotype-phenotype correlations in 22q13 deletion syndrome and SHANK3 deficiency

PubMed Central

2013-01-01

Background 22q13 deletion syndrome, also known as Phelan-McDermid syndrome, is a neurodevelopmental disorder characterized by intellectual disability, hypotonia, delayed or absent speech, and autistic features. SHANK3 has been identified as the critical gene in the neurological and behavioral aspects of this syndrome. The phenotype of SHANK3 deficiency has been described primarily from case studies, with limited evaluation of behavioral and cognitive deficits. The present study used a prospective design and inter-disciplinary clinical evaluations to assess patients with SHANK3 deficiency, with the goal of providing a comprehensive picture of the medical and behavioral profile of the syndrome. Methods A serially ascertained sample of patients with SHANK3 deficiency (n = 32) was evaluated by a team of child psychiatrists, neurologists, clinical geneticists, molecular geneticists and psychologists. Patients were evaluated for autism spectrum disorder using the Autism Diagnostic Interview-Revised and the Autism Diagnostic Observation Schedule-G. Results Thirty participants with 22q13.3 deletions ranging in size from 101 kb to 8.45 Mb and two participants with de novo SHANK3 mutations were included. The sample was characterized by high rates of autism spectrum disorder: 27 (84%) met criteria for autism spectrum disorder and 24 (75%) for autistic disorder. Most patients (77%) exhibited severe to profound intellectual disability and only five (19%) used some words spontaneously to communicate. Dysmorphic features, hypotonia, gait disturbance, recurring upper respiratory tract infections, gastroesophageal reflux and seizures were also common. Analysis of genotype-phenotype correlations indicated that larger deletions were associated with increased levels of dysmorphic features, medical comorbidities and social communication impairments related to autism. Analyses of individuals with small deletions or point mutations identified features related to SHANK3 haploinsufficiency, including ASD, seizures and abnormal EEG, hypotonia, sleep disturbances, abnormal brain MRI, gastroesophageal reflux, and certain dysmorphic features. Conclusions This study supports findings from previous research on the severity of intellectual, motor, and speech impairments seen in SHANK3 deficiency, and highlights the prominence of autism spectrum disorder in the syndrome. Limitations of existing evaluation tools are discussed, along with the need for natural history studies to inform clinical monitoring and treatment development in SHANK3 deficiency. PMID:23758760

Autosomal recessive Robinow syndrome (OMIM 268310) is a condition caused by mutations in the ROR2 gene, the receptor tyrosine kinase-like orphan receptor 2. The main characteristic features are: a face resembling that of a fetus, cleft lip and palate, mesomelic limb shortening, a micropenis in males, hydronephrosis or urinary tract infections, and skeletal and vertebral anomalies. This study reports two sisters from a consanguineous Lebanese family with an autosomal recessive Robinow syndrome. Both presented with short stature, dysmorphic facial features, and mild bone abnormalities. One of the affected girls had a malformation of her right hand: a mesoaxial polydactyly combined with a syndactyly of the 3rd and 4th fingers, and a short right 3rd metacarpal bone. Molecular analysis of the ROR2 gene revealed the presence of a previously undescribed missense mutation: p.R272C (c.814C>T), in the cysteine-rich domain of the protein. These patients are compared with other cases, and a phenotype-genotype correlation is discussed. Copyright © 2011 Elsevier Masson SAS. All rights reserved.

We describe an X-linked genetic syndrome associated with mutations in TAF1 and manifesting with global developmental delay, intellectual disability (ID), characteristic facial dysmorphology, generalized hypotonia, and variable neurologic features, all in male individuals. Simultaneous studies using diverse strategies led to the identification of nine families with overlapping clinical presentations and affected by de novo or maternally inherited single-nucleotide changes. Two additional families harboring large duplications involving TAF1 were also found to share phenotypic overlap with the probands harboring single-nucleotide changes, but they also demonstrated a severe neurodegeneration phenotype. Functional analysis with RNA-seq for one of the families suggested that the phenotype is associated with downregulation of a set of genes notably enriched with genes regulated by E-box proteins. In addition, knockdown and mutant studies of this gene in zebrafish have shown a quantifiable, albeit small, effect on a neuronal phenotype. Our results suggest that mutations in TAF1 play a critical role in the development of this X-linked ID syndrome. Copyright © 2015 The Authors. Published by Elsevier Inc. All rights reserved.

Background Gender is a critically important moderator of psychopathology. However, gender similarities and differences in body dysmorphic disorder (BDD) have received scant investigation. In this study, we examined gender similarities and differences in the broadest sample in which this topic has been examined. Methods Two hundred subjects with BDD recruited from diverse sources were assessed with a variety of standard measures. Results There were more similarities than differences between men and women, but many gender differences were found. The men were significantly older and more likely to be single and living alone. Men were more likely to obsess about their genitals, body build, and thinning hair/balding; excessively lift weights; and have a substance use disorder. In contrast, women were more likely to obsess about their skin, stomach, weight, breasts/chest, buttocks, thighs, legs, hips, toes, and excessive body/facial hair, and they were excessively concerned with more body areas. Women also performed more repetitive and safety behaviors, and were more likely to camouflage and use certain camouflaging techniques, check mirrors, change their clothes, pick their skin, and have an eating disorder. Women also had earlier onset of subclinical BDD symptoms and more severe BDD as assessed by the Body Dysmorphic Disorder Examination. However, men had more severe BDD as assessed by the Psychiatric Status Rating Scale for Body Dysmorphic Disorder, and they had poorer Global Assessment of Functioning Scale scores, were less likely to be working because of psychopathology, and were more likely to be receiving disability, including disability for BDD. Conclusions The clinical features of BDD in men and women have many similarities but also some interesting and important differences. These findings have implications for the detection and treatment of BDD. PMID:16490564

Objective To determine the clinical correlates of dysmorphic concern in persons seeking cosmetic enhancement from cosmetic physicians. Method A questionnaire survey of 137 patients attending the practices of two cosmetic physicians. Results Four subjects (2.9%; 95% CI = 0.8%–7.3%) had a diagnosis of body dysmorphic disorder (BDD), but many more expressed overconcern with physical appearance (‘dysmorphic concern’). Dysmorphic concern accounted for a substantial amount of the variance for mood, social anxiety, and impairment in work and social functioning, while concerns related to how self or others perceive the putative flaw in appearance, impacted significantly on work and leisure activities, but did not apparently influence mood and social anxiety to any significant degree. Conclusions Dysmorphic concern is a broad dimensional construct that is related to both inter- and intrapsychic distress and disablement associated with people seeking cosmetic enhancement PMID:15209836

The ASXL genes (ASXL1, ASXL2, and ASXL3) participate in body patterning during embryogenesis and encode proteins involved in epigenetic regulation and assembly of transcription factors to specific genomic loci. Germline de novo truncating variants in ASXL1 and ASXL3 have been respectively implicated in causing Bohring-Opitz and Bainbridge-Ropers syndromes, which result in overlapping features of severe intellectual disability and dysmorphic features. ASXL2 has not yet been associated with a human Mendelian disorder. In this study, we performed whole-exome sequencing in six unrelated probands with developmental delay, macrocephaly, and dysmorphic features. All six had de novo truncating variants in ASXL2. A careful review enabled the recognition of a specific phenotype consisting of macrocephaly, prominent eyes, arched eyebrows, hypertelorism, a glabellar nevus flammeus, neonatal feeding difficulties, hypotonia, and developmental disabilities. Although overlapping features with Bohring-Opitz and Bainbridge-Ropers syndromes exist, features that distinguish the ASXL2-associated condition from ASXL1- and ASXL3-related disorders are macrocephaly, absence of growth retardation, and more variability in the degree of intellectual disabilities. We were also able to demonstrate with mRNA studies that these variants are likely to exert a dominant-negative effect, given that both alleles are expressed in blood and the mutated ASXL2 transcripts escape nonsense-mediated decay. In conclusion, de novo truncating variants in ASXL2 underlie a neurodevelopmental syndrome with a clinically recognizable phenotype. This report expands the germline disorders that are linked to the ASXL genes. Copyright © 2016. Published by Elsevier Inc.

Background Individuals affected with DiGeorge and Velocardiofacial syndromes present with both phenotypic diversity and variable expressivity. The most frequent clinical features include conotruncal congenital heart defects, velopharyngeal insufficiency, hypocalcemia and a characteristic craniofacial dysmorphism. The etiology in most patients is a 3 Mb recurrent deletion in region 22q11.2. However, cases of infrequent deletions and duplications with different sizes and locations have also been reported, generally with a milder, slightly different phenotype for duplications but with no clear genotype-phenotype correlation to date. Methods We present a 7 month-old male patient with surgically corrected ASD and multiple VSDs, and dysmorphic facial features not clearly suggestive of 22q11.2 deletion syndrome, and a newborn male infant with cleft lip and palate and upslanting palpebral fissures. Karyotype, FISH, MLPA, microsatellite markers segregation studies and SNP genotyping by array-CGH were performed in both patients and parents. Results Karyotype and FISH with probe N25 were normal for both patients. MLPA analysis detected a partial de novo 1.1 Mb deletion in one patient and a novel partial familial 0.4 Mb duplication in the other. Both of these alterations were located at a distal position within the commonly deleted region in 22q11.2. These rearrangements were confirmed and accurately characterized by microsatellite marker segregation studies and SNP array genotyping. Conclusion The phenotypic diversity found for deletions and duplications supports a lack of genotype-phenotype correlation in the vicinity of the LCRC-LCRD interval of the 22q11.2 chromosomal region, whereas the high presence of duplications in normal individuals supports their role as polymorphisms. We suggest that any hypothetical correlation between the clinical phenotype and the size and location of these alterations may be masked by other genetic and/or epigenetic modifying factors.

The clinical diagnosis was based on the triad of characteristic facial abnormalities (long palpebral fissures, a broad and depressed nasal tip, large prominent earlobes, small head), growth retardation, (DDH). In this paper the authors report the first case of Kabuki syndrome associated with café au lait spots.

Social-evaluative versus self-evaluative appearance concerns in Body Dysmorphic Disorder.

PubMed

Anson, Martin; Veale, David; de Silva, Padmal

2012-12-01

Body Dysmorphic Disorder (BDD) is characterised by significant preoccupation and distress relating to an imagined or slight defect in appearance. Individuals with BDD frequently report marked concerns relating to perceived negative evaluation of their appearance by others, but research specifically investigating such concerns remains limited. This study investigated the extent and nature of appearance-related social-evaluative and self-evaluative concerns in individuals with BDD and healthy controls. BDD participants, in comparison to controls, reported high levels of importance and anxiety associated with perceptions of others' views of their appearance, in addition to their own view. No differences were observed in the level of importance and anxiety associated with their self-view in comparison to others' views. These findings support existing evidence indicating that appearance-related social-evaluative concerns are a central feature of BDD. Cognitive-behavioural treatment implications are discussed.

Demir, Korcan; Altıncık, Ayça; Böber, Ece

2013-01-01

3-M syndrome is an underdiagnosed autosomal recessive disorder characterized by severe pre- and postnatal growth retardation with minimal dysmorphic features and distinguishing radiological findings. We report a patient who was first admitted at 7.5 years of age. He was born to consanguineous parents with a birth weight of 2250 g. Physical examination revealed a severe short stature (height, 95 cm; SD score -5.64) and minimal dysmorphic features. Biochemistry, endocrine work-up, and karyotype were normal. Reevaluation at 16.5 years of age revealed a height of 128.5 cm (SD score -5.27), prominent forehead, anteverted nasal openings, fleshy nasal tip, full lips, malar hypoplasia, hyperlordosis, prominent heels, testicular volumes 8-10 mL, and pubic hair consistent with Tanner stage II. Growth hormone trial for a year resulted in inadequate height gain (3 cm). The diagnosis of 3-M syndrome was made upon typical findings (thin long bones with diaphyseal narrowing and tall lumbar vertebrae) in a recent skeletal survey. Genetic analysis disclosed a homozygote frame shift mutation in exon 2: c.457_458delinsT resulting in p.Gly153fs.

Patient: Female, 6 Final Diagnosis: Phenotype-genotype discordance in congenital malformations with communication disorders resembling trisomy 18 (Edwards syndrome) Symptoms: — Medication: — Clinical Procedure: — Specialty: Otolaryngology Objective: Congenital defects Background: Communication process disorders are very frequent in rare cases of chromosomal aberrations (deletions, insertions, and trisomies) such as Down syndrome (trisomy 21), Turner syndrome, Edwards syndrome (trisomy 18), or Patau syndrome (trisomy 13). Sometimes phenotype may delusively correspond to the characteristic features of a given syndrome, but genotype tests do not confirm its presence. Case Report: We present the case of a 6-year-old girl admitted to the Clinic of Phoniatrics and Audiology for the assessment of communication in the course of congenital malformations with phenotype characteristic for trisomy 18 (Edwards syndrome). Immediately upon birth, dysmorphic changes suggesting trisomy 18 (Edwards syndrome) were observed, but trisomy 18 was excluded after karyotype test results were normal (46, XX). Conclusions: Disturbed articulation was diagnosed: deformed linguo-dental and palatal sounds, interdental realization with flat tongue of the /s/, /z/, /c/, /dz/, /ś/, /ź/, /ć/, /dz/ sounds (sigmatismus interdentalis). Hearing loss was confirmed. PMID:24478819

SOX5 encodes a transcription factor involved in the regulation of chondrogenesis and the development of the nervous system. Despite its important developmental roles, SOX5 disruption has yet to be associated with human disease. We report one individual with a reciprocal translocation breakpoint within SOX5, eight individuals with intragenic SOX5 deletions (four are apparently de novo and one inherited from an affected parent), and seven individuals with larger 12p12 deletions encompassing SOX5. Common features in these subjects include prominent speech delay, intellectual disability, behavior abnormalities, and dysmorphic features. The phenotypic impact of the deletions may depend on the location of the deletion and, consequently, which of the three major SOX5 protein isoforms are affected. One intragenic deletion, involving only untranslated exons, was present in a more mildly affected subject, was inherited from a healthy parent and grandparent, and is similar to a deletion found in a control cohort. Therefore, some intragenic SOX5 deletions may have minimal phenotypic effect. Based on the location of the deletions in the subjects compared to the controls, the de novo nature of most of these deletions, and the phenotypic similarities among cases, SOX5 appears to be a dosage-sensitive, developmentally important gene. © 2012 Wiley Periodicals, Inc.

The goal of this study was to examine the role of rejection sensitivity in the relationship between social anxiety and body dysmorphic concerns. To test our hypothesis that rejection sensitivity mediates the link between social anxiety and body dysmorphic concerns, we administered self-report questionnaires to 209 student volunteers. Consistent with our prediction, rejection sensitivity partially mediated the relationship between social anxiety symptoms and body dysmorphic concerns. The implications of the overlap between these constructs are discussed. PMID:21741203

Dysmorphic concern (DC) refers to excessive preoccupation with a slight or imagined defect in physical appearance with social avoidance and behavior directed at controlling the defect in appearance. This study attempted to adapt the factor structure of two instruments that cover the DC construct, the Dysmorphic Concern Questionnaire (DCQ) and the Body Dysmorphic Disorder Examination Self-Report (BDDE-SR), to Spanish and establish their psychometric properties. A total of 920 subjects (62.7% women, Mage = 32.44 years) participated. Exploratory and Confirmatory Factor Analysis of both scales found adequate goodness of fit indices. A one-dimensional structure was found for the DCQ and two first-order factors (dissatisfaction/preoccupation with body image (BI) and BI avoidance behavior) were identified for the BDDE-SR. The psychometric test–retest reliability and validity properties (content, convergent, and discriminant) were satisfactory. It is suggested that the DC construct includes both cognitive and behavioral aspects and may represent a continuum of severity with Body Dysmorphic Disorder at the end. PMID:28713311

Dysmorphic concern is related to delusional proneness and negative affect in a community sample.

Body image concerns are common in the general population and in some mental illnesses reach pathological levels. We investigated whether dysmorphic concern with appearance (a preoccupation with minor or imagined defects in appearance) is explained by psychotic processes in a community sample. In a cross-sectional design, two hundred and twenty six participants completed an online survey battery including: The Dysmorphic Concern Questionnaire; the Peters Delusional inventory; the Aberrant Salience Inventory; and the Depression, Anxiety, Stress Scale. Participants were native English speakers residing in Australia. Dysmorphic concern was positively correlated with delusional proneness, aberrant salience and negative emotion. Regression established that negative emotion and delusional proneness predicted dysmorphic concern, whereas, aberrant salience did not. Although delusional proneness was related to body dysmorphia, there was no evidence that it was related to aberrant salience. Understanding the contribution of other psychosis processes, and other health related variables to the severity of dysmorphic concern will be a focus of future research.

Body dysmorphic disorder is a mental disorder characterized by a preoccupation with some aspect of one's appearance. In cosmetic surgery, this preoccupation can be overlooked by practitioners resulting in a discrepancy between expected and realistic outcome. Identifying the characteristics of this disorder may be crucial to the practitioner-patient relationship in the plastic surgery setting.

Body Dysmorphic Disorder: Contraindication or Ethical Justification for Female Genital Cosmetic Surgery in Adolescents.

PubMed

Spriggs, Merle; Gillam, Lynn

2016-11-01

Is Female Genital Cosmetic Surgery for an adolescent with Body Dysmorphic Disorder ever ethically justified? Cosmetic genital surgery (specifically labioplasty) for adolescent girls is one of the most ethically controversial forms of cosmetic surgery and Body Dysmorphic Disorder is typically seen as a contraindication for cosmetic surgery. Two key ethical concerns are (1) that Body Dysmorphic Disorder undermines whatever capacity for autonomy the adolescent has; and (2) even if there is valid parental consent, the presence of Body Dysmorphic Disorder means that cosmetic surgery will fail in its aims. In this article, we challenge, in an evidence-based way, the standard view that Body Dysmorphic Disorder is a contraindication for genital cosmetic surgery in adolescents. Our argument gathers together and unifies a substantial amount of disparate research in the context of an ethical argument. We focus on empirical questions about benefit and harm, because these are ethically significant. Answers to these questions affect the answer to the ethical question. We question the claim that there would be no benefit from surgery in this situation, and we consider possible harms that might be done if treatment is refused. For an adolescent with Body Dysmorphic Disorder, the most important thing may be to avoid harm. We find ourselves arguing for the ethical justifiability of cosmetic labioplasty for an adolescent with Body Dysmorphic Disorder, even though we recognize that it is a counter intuitive position. We explain how we reached our conclusion. © 2016 John Wiley & Sons Ltd.

Neonatal diabetes and hypothyroidism (NDH) syndrome was first described in 2003 in a consanguineous Saudi Arabian family where two out of four siblings were reported to have presented with proportionate IUGR, neonatal non-autoimmune diabetes mellitus, severe congenital hypothyroidism, cholestasis, congenital glaucoma, and polycystic kidneys. Liver disease progressed to hepatic fibrosis. The renal disease was characterized by enlarged kidneys and multiple small cysts with deficient cortico-medullary junction differentiation and normal kidney function. There was minor facial dysmorphism (depressed nasal bridge, large anterior fontanelle, long philtrum) reported but no facial photographs were published. Mutations in the transcription factor GLI-similar 3 (GLIS3) gene in the original family and two other families were subsequently reported in 2006. All affected individuals had neonatal diabetes, congenital hypothyroidism but glaucoma and liver and kidney involvement were less consistent features. Detailed descriptions of the facial dysmorphism have not been reported previously. In this report, we describe the common facial dysmorphism consisting of bilateral low-set ears, depressed nasal bridge with overhanging columella, elongated, upslanted palpebral fissures, persistent long philtrum with a thin vermilion border of the upper lip in a cohort of seven patients with GLIS3 mutations and report the emergence of a distinct, probably recognizable facial gestalt in this group which evolves with age. © 2016 Wiley Periodicals, Inc. © 2016 Wiley Periodicals, Inc.

Small supernumerary marker chromosomes (sSMC) occur with a frequency of approximately 0.4 per 1000 newborns and are more frequent in the population with mental retardation and/or with dysmorphic signs. Small supernumerary chromosome rings (sSCR) usually occur as apart of a mosaic karyotype (Liehr et al., 2004). Chromosome 19 supernumerary rings are very rare. Almost all cases of sSMC19 have been reported on Thomas Liehr's website (http://www.med.uni-jena.de/fish/sSMC/19.htm#Start19). Of these cases, 14 were with phenotypic abnormalities and a clear characterization of the sSMC; two cases were suitable for comparison with our case with regard to their genetic content, but not with regard to the structure ofthe sSMC (Manvelyan et al., 2008). The phenotype, associated with partial trisomy 19q, includes facial dysmorphism, growth and mental retardation, macrocephaly, heart malformation and anomalies of the genitourinary and gastrointestinal tracts. The phenotype associated with partial trisomy 19p is characterized by dysmorphic features, severe mental retardation, abnormalities of brain morphology and anomalies of the fingers (Tercanli et al., 2000; Qorri et al., 2002; Novelli et al., 2005; Vraneković et al., 2008). Herein, we report the phenotype and molecular cytogenetic analysis in a patient with the smallest de-novo constitutional ring extended from the p12 to q12 region of chromosome 19.

Leigh syndrome is an inherited, progressive neurodegenerative disorder of infancy and childhood. Mutations in the nuclear SURF-1 gene are specifically associated with cytochrome C oxidase-deficient Leigh syndrome. This report describes two patients with similar facial features. One of them was a 2(1/2)-year-old male, and the other was a 3-year-old male with a mutation in SURF-1 gene and facial dysmorphism including frontal bossing, brachycephaly, hypertrichosis, lateral displacement of inner canthi, esotropia, maxillary hypoplasia, hypertrophic gums, irregularly placed teeth, upturned nostril, low-set big ears, and retrognathi. The first patient's magnetic resonance imaging at 15 months of age indicated mild symmetric T2 prolongation involving the subthalamic nuclei. His second magnetic resonance imaging at 2 years old revealed a symmetric T2 prolongation involving the subthalamic nuclei, substantia nigra, and medulla lesions. In the second child, at the age of 2 the first magnetic resonance imaging documented heavy brainstem and subthalamic nuclei involvement. A second magnetic resonance imaging, performed when he was 3 years old, revealed diffuse involvement of the substantia nigra and hyperintense lesions of the central tegmental tract in addition to previous lesions. Facial dysmorphism and magnetic resonance imaging findings, observed in these cases, can be specific findings in Leigh syndrome patients with cytochrome C oxidase deficiency. SURF-1 gene mutations must be particularly reviewed in such patients.

Resistance to thyroid hormone β (RTH β ) due to homozygous THRB defects is exceptionally rare, with only five kindreds reported worldwide. Cardiac dysfunction, which can be life-threatening, is recognized in the disorder. Here we describe the clinical, metabolic, ophthalmic, and cardiac findings in a 9-year-old boy harboring a biallelic THRB mutation (R243Q), along with biochemical, physiologic, and cardiac responses to carbimazole and triiodothyroacetic acid (TRIAC) therapy. The patient exhibits recognized features (goiter, nonsuppressed thyroid-stimulating hormone levels, upper respiratory tract infections, hyperactivity, low body mass index) of heterozygous RTH β , with additional characteristics (dysmorphic facies, winging of scapulae) and more markedly elevated thyroid hormone levels, associated with the homozygous form of the disorder. Notably, an older sibling with similar clinical features and probable homozygous RTH β had died of cardiac failure at age 13 years. Features of early dilated cardiomyopathy in our patient prompted combination treatment with carbimazole and TRIAC. Careful titration of therapy limited elevation in TSH levels and associated increase in thyroid volume. Subsequently, sustained reduction in thyroid hormones with normal TSH levels was reflected in lower basal metabolic rate, gain of lean body mass, and improved growth and cardiac function. A combination of antithyroid drug and TRIAC therapy may prevent thyrotoxic cardiomyopathy and its decompensation in homozygous or even heterozygous RTH β in which life-threatening hyperthyroid features predominate.

Deletions in the 2p16.3 region that includes the neurexin (NRXN1) gene are associated with intellectual disability and various psychiatric disorders, in particular, autism and schizophrenia. We present three unrelated patients, two adults and one child, in whom we identified an intragenic 2p16.3 deletion within the NRXN1 gene using an oligonucleotide comparative genomic hybridization array. The three patients presented dual diagnosis that consisted of mild intellectual disability and autism and bipolar disorder. Also, they all shared a dysmorphic phenotype characterized by a long face, deep set eyes, and prominent premaxilla. Genetic analysis of family members showed two inherited deletions. A comprehensive neuropsychological examination of the 2p16.3 deletion carriers revealed the same phenotype, characterized by anxiety disorder, borderline intelligence, and dysexecutive syndrome. The cognitive pattern of dysexecutive syndrome with poor working memory and reduced attention switching, mental flexibility, and verbal fluency was the same than those of the adult probands. We suggest that in addition to intellectual disability and psychiatric disease, NRXN1 deletion is a risk factor for a characteristic cognitive and dysmorphic profile. The new cognitive phenotype found in the 2p16.3 deletion carriers suggests that 2p16.3 deletions might have a wide variable expressivity instead of incomplete penetrance. PMID:25614873

Segmental duplications, which comprise ∼5%–10% of the human genome, are known to mediate medically relevant deletions, duplications, and inversions through nonallelic homologous recombination (NAHR) and have been suggested to be hot spots in chromosome evolution and human genomic instability. We report seven individuals with microdeletions at 17q23.1q23.2, identified by microarray-based comparative genomic hybridization (aCGH). Six of the seven deletions are ∼2.2 Mb in size and flanked by large segmental duplications of >98% sequence identity and in the same orientation. One of the deletions is ∼2.8 Mb in size and is flanked on the distal side by a segmental duplication, whereas the proximal breakpoint falls between segmental duplications. These characteristics suggest that NAHR mediated six out of seven of these rearrangements. These individuals have common features, including mild to moderate developmental delay (particularly speech delay), microcephaly, postnatal growth retardation, heart defects, and hand, foot, and limb abnormalities. Although all individuals had at least mild dysmorphic facial features, there was no characteristic constellation of features that would elicit clinical suspicion of a specific disorder. The identification of common clinical features suggests that microdeletions at 17q23.1q23.2 constitute a novel syndrome. Furthermore, the inclusion in the minimal deletion region of TBX2 and TBX4, transcription factors belonging to a family of genes implicated in a variety of developmental pathways including those of heart and limb, suggests that these genes may play an important role in the phenotype of this emerging syndrome.

Visual selective attention in body dysmorphic disorder, bulimia nervosa and healthy controls.

Cognitive behavioral models postulate that selective attention plays an important role in the maintenance of body dysmorphic disorder (BDD). It is suggested that individuals with BDD overfocus on perceived defects in their appearance, which may contribute to the excessive preoccupation with their appearance. The present study used eye tracking to examine visual selective attention in individuals with BDD (n=19), as compared to individuals with bulimia nervosa (BN) (n=21) and healthy controls (HCs) (n=21). Participants completed interviews, questionnaires, rating scales and an eye tracking task: Eye movements were recorded while participants viewed photographs of their own face and attractive as well as unattractive other faces. Eye tracking data showed that BDD and BN participants focused less on their self-rated most attractive facial part than HCs. Scanning patterns in own and other faces showed that BDD and BN participants paid as much attention to attractive as to unattractive features in their own face, whereas they focused more on attractive features in attractive other faces. HCs paid more attention to attractive features in their own face and did the same in attractive other faces. Results indicate an attentional bias in BDD and BN participants manifesting itself in a neglect of positive features compared to HCs. Perceptual retraining may be an important aspect to focus on in therapy in order to overcome the neglect of positive facial aspects. Future research should aim to disentangle attentional processes in BDD by examining the time course of attentional processing. Copyright © 2016 Elsevier Inc. All rights reserved.

The clinical understanding of the CDKL5 disorder remains limited, with most information being derived from small patient groups seen at individual centres. This study uses a large international data collection to describe the clinical profile of the CDKL5 disorder and compare with Rett syndrome (RTT). Information on individuals with cyclin-dependent kinase-like 5 (CDKL5) mutations (n=86) and females with MECP2 mutations (n=920) was sourced from the InterRett database. Available photographs of CDKL5 patients were examined for dysmorphic features. The proportion of CDKL5 patients meeting the recent Neul criteria for atypical RTT was determined. Logistic regression and time-to-event analyses were used to compare the occurrence of Rett-like features in those with MECP2 and CDKL5 mutations. Most individuals with CDKL5 mutations had severe developmental delay from birth, seizure onset before the age of 3 months and similar non-dysmorphic features. Less than one-quarter met the criteria for early-onset seizure variant RTT. Seizures and sleep disturbances were more common than in those with MECP2 mutations whereas features of regression and spinal curvature were less common. The CDKL5 disorder presents with a distinct clinical profile and a subtle facial, limb and hand phenotype that may assist in differentiation from other early-onset encephalopathies. Although mutations in the CDKL5 gene have been described in association with the early-onset variant of RTT, in our study the majority did not meet these criteria. Therefore, the CDKL5 disorder should be considered separate to RTT, rather than another variant.

Potocki-Lupski syndrome (PTLS [MIM 610883]) is a recently recognized microduplication syndrome associated with 17p11.2. It is characterized by mild facial dysmorphic features, hypermetropia, infantile hypotonia, failure to thrive, mental retardation, autistic spectrum disorders, behavioral abnormalities, sleep apnea, and cardiovascular anomalies. In several studies, the critical PTLS region was deduced to be 1.3Mb in length, and included RAI1 and 17 other genes. We report a 3-year-old Korean boy with the smallest duplication in 17p11.2 and a milder phenotype. He had no family history of neurologic disease or developmental delay and no history of seizure, autistic features, or behavior problems. He showed subtle facial dysmorphic features (dolichocephaly and a mildly asymmetric smile) and flat feet. All laboratory tests were normal and he had no evidence of internal organ anomalies. He was found to have mild intellectual disabilities (full scale IQ 65 on K-WPPSI) and language developmental delay (age of 2.2year-old on PRESS). Array comparative genomic hybridization (CGH) showed about a 0.25Mb microduplication on chromosome 17p11.2 containing four Refseq (NCBI reference sequence) genes, including RAI1 [arr 17p11.2(17,575,978-17,824,623)×3]. When compared with previously reported cases, the milder phenotype of our patient may be associated with the smallest duplication in 17p11.2, 0.25Mb in length.

Dermatologists are increasingly confronted with patients affected by body dysmorphic disorder (BDD). BDD is characterized by excessive preoccupation with one or more perceived defect(s) or flaw(s) in physical appearance which are not observable or appear slight to others. So far, there have been only few studies examining the prevalence of BDD in dermatological outpatients. In addition, the need for psychotherapeutic support in dermatological outpatients with body dysmorphic concerns has not yet been systematically examined. The objective of the present study was therefore to investigate the frequency of body dysmorphic concerns as well as social adaptation and the need for psychotherapeutic support in the aforementioned patient group. A total of 252 dermatological outpatients seen at a German university hospital were consecutively enrolled, and examined using the Dysmorphic Concerns Questionnaire, the Social Adaptation Self-Evaluation Scale, and the German version of the University of Rhode Island Change Assessment Scale. 7.9 % of all outpatients (unselected sample) showed positive test results, suggesting clinically relevant body dysmorphic concerns. Patients with clinically relevant body dysmorphic concerns exhibited poor social adaptation. Contrary to expectations, these patients revealed a high motivation for change, indicating the necessity for psychotherapeutic support. Our findings confirm previous prevalence rates of BDD in dermatological outpatients, and highlight the need for providing psychotherapeutic support to dermatological patients. © 2016 Deutsche Dermatologische Gesellschaft (DDG).

To quantify the osseous anatomy of the dysmorphic third sacral segment and assess its ability to accommodate internal fixation. Retrospective chart review of a trauma database. University Level 1 Trauma Center. Fifty-nine patients over the age of 18 with computed tomography scans of the pelvis separated into 2 groups: a group with normal pelvic anatomy and a group with sacral dysmorphism. The sacral osseous area was measured on computed tomography scans in the axial, coronal, and sagittal planes in normal and dysmorphic pelves. These measurements were used to determine the possibility of accommodating a transiliac transsacral screw in the third sacral segment. In the normal group, the S3 coronal transverse width averaged 7.71 mm and the S3 axial transverse width averaged 7.12 mm. The mean S3 cross-sectional area of the normal group was 55.8 mm. The dysmorphic group was found to have a mean S3 coronal transverse width of 9.49 mm, an average S3 axial transverse width of 9.14 mm, and an S3 cross-sectional area of 77.9 mm. The third sacral segment of dysmorphic sacra has a larger osseous pathway available to safely accommodate a transiliac transsacral screw when compared with normal sacra. The S3 segment of dysmorphic sacra can serve as an additional site for screw placement when treating unstable posterior pelvic ring fractures.

Dysmorphic concern refers to an excessive preoccupation with a perceived or slight defect in physical appearance. It lies on a continuum of severity from no or minimal concerns to severe concerns over one's appearance. The present study examined the heritability of dysmorphic concerns in a large sample of twins. Twins from the St Thomas UK twin registry completed a valid and reliable self-report measure of dysmorphic concerns, which also includes questions about perceived body odour and malfunction. Twin modelling methods (female twins only, n=3544) were employed to decompose the variance in the liability to dysmorphic concerns into additive genetic, shared and non-shared environmental factors. Model-fitting analyses showed that genetic factors accounted for approximately 44% [95% confidence intervals (CI) 36-50%] of the variance in dysmorphic concerns, with non-shared environmental factors and measurement error accounting for the remaining variance (56%; 95% CI 50-63%). Shared environmental factors were negligible. The results remained unchanged when excluding individuals reporting an objective medical condition/injury accounting for their concern in physical appearance. Over-concern with a perceived or slight defect in physical appearance is a heritable trait, with non-shared environmental factors also playing an important role in its causation. The results are relevant for various psychiatric disorders characterized by excessive concerns in body appearance, odour or function, including but not limited to body dysmorphic disorder.

Atelosteogenesis type 2 (AO2) (MIM 256050) is a neonatally lethal chondrodysplasia characterised by severe limb shortening and deficient ossification of parts of the skeleton. Other features include facial dysmorphism, cleft palate, talipes, and abducted thumbs and toes. Phenotypic overlap with non-lethal diastrophic dysplasia (DTD) suggested a common aetiology and it has recently been confirmed that both syndromes result from mutations in the DTDST (diastrophic dysplasia sulphate transporter) gene.

The purpose of our study was to describe the CT and MRI features of primary PEComas of the liver and to document the associated clinical outcomes. Retrospective study included 20 patients with primary hepatic perivascular epithelioid cell tumors (PEComa) with pathology and clinical outcomes for correlation. Study group included 20 patients: 16 women, 4 men; mean age 53 (range 35-77) years. Initial pathology diagnoses were classic angiomyolipoma (AML) (n = 11), epithelioid AML (n = 7), and PEComa not otherwise specified (n = 2). Mean tumor size was 5.1 (range 1.3-15.0) cm. CT/MRI features included well-defined margins 20/20 (100%), arterial enhancement 18/19 (95%), subcapsular location 17/20 (85%), heterogeneous 16/20 (80%), dysmorphic vessels 14/20 (70%), fat 13/20 (65%), hemorrhage 4/20 (20%), cystic components 4/20 (20%), and calcification 1/20 (5%). At the time of discovery, 18 patients were asymptomatic and their tumors were incidentally detected on imaging, and 2 patients were symptomatic. Ultimately, 18 tumors were benign and 2 developed metastases. On CT/MRI, most primary hepatic PEComas were well-defined, arterial enhancing, subcapsular, heterogeneous masses that often had dysmorphic vessels and contained fat. Most tumors were benign but complications included local symptoms, bleeding, and malignant change.

Neuroligins are post-synaptic, cellular adhesion molecules implicated in synaptic formation and function. NLGN2 is strongly linked to inhibitory, GABAergic signaling and is crucial for maintaining the excitation-inhibition balance in the brain. Disruption of the excitation-inhibition balance is associated with neuropsychiatric disease. In animal models, altered NLGN2 expression causes anxiety, developmental delay, motor discoordination, social impairment, aggression, and sensory processing defects. In humans, mutations in NLGN3 and NLGN4 are linked to autism and schizophrenia; NLGN2 missense variants are implicated in schizophrenia. Copy number variants encompassing NLGN2 on 17p13.1 are associated with autism, intellectual disability, metabolic syndrome, diabetes, and dysmorphic features, but an isolated NLGN2 nonsense variant has not yet been described in humans. Here, we describe a 15-year-old male with severe anxiety, obsessive-compulsive behaviors, developmental delay, autism, obesity, macrocephaly, and some dysmorphic features. Exome sequencing identified a heterozygous, de novo, c.441C>A p.(Tyr147Ter) variant in NLGN2 that is predicted to cause loss of normal protein function. This is the first report of an NLGN2 nonsense variant in humans, adding to the accumulating evidence that links synaptic proteins with a spectrum of neurodevelopmental phenotypes. © 2016 Wiley Periodicals, Inc. © 2016 Wiley Periodicals, Inc.

Phosphatidyl inositol glycan (PIG) enzyme subclasses are involved in distinct steps of glycosyl phosphatidyl inositol anchor protein biosynthesis. Glycolsyl phosphatidyl inositol-anchored proteins have heterogeneous functions; they can function as enzymes, adhesion molecules, complement regulators and co-receptors in signal transduction pathways. Germline mutations in genes encoding different members of the PIG family result in diverse conditions with (severe) developmental delay, (neonatal) seizures, hypotonia, CNS abnormalities, growth abnormalities, and congenital abnormalities as hallmark features. The variability of clinical features resembles the typical diversity of other glycosylation pathway deficiencies such as the congenital disorders of glycosylation. Here, we report the first germline missense mutation in the PIGA gene associated with accelerated linear growth, obesity, central hypotonia, severe refractory epilepsy, cardiac anomalies, mild facial dysmorphic features, mildly elevated alkaline phosphatase levels, and CNS anomalies consisting of progressive cerebral atrophy, insufficient myelinization, and cortical MRI signal abnormalities. X-exome sequencing in the proband identified a c.278C>T (p.Pro93Leu) mutation in the PIGA gene. The mother and maternal grandmother were unaffected carriers and the mother showed 100% skewing of the X-chromosome harboring the mutation. These results together with the clinical similarity of the patient reported here and the previously reported patients with a germline nonsense mutation in PIGA support the determination that this mutation caused the phenotype in this family. © 2013 Wiley Periodicals, Inc.

Familial testicular germ cell tumor: no associated syndromic pattern identified

PubMed Central

2014-01-01

Background Testicular germ cell tumor (TGCT) is the most common malignancy in young men. Familial clustering, epidemiologic evidence of increased risk with family or personal history, and the association of TGCT with genitourinary (GU) tract anomalies have suggested an underlying genetic predisposition. Linkage data have not identified a rare, highly-penetrant, single gene in familial TGCT (FTGCT) cases. Based on its association with congenital GU tract anomalies and suggestions that there is an intrauterine origin to TGCT, we hypothesized the existence of unrecognized dysmorphic features in FTGCT. Methods We evaluated 38 FTGCT individuals and 41 first-degree relatives from 22 multiple-case families with detailed dysmorphology examinations, physician-based medical history and physical examination, laboratory testing, and genitourinary imaging studies. Results The prevalence of major abnormalities and minor variants did not significantly differ between either FTGCT individuals or their first-degree relatives when compared with normal population controls, except for tall stature, macrocephaly, flat midface, and retro-/micrognathia. However, these four traits were not manifest as a constellation of features in any one individual or family. We did detect an excess prevalence of the genitourinary anomalies cryptorchidism and congenital inguinal hernia in our population, as previously described in sporadic TGCT, but no congenital renal, retroperitoneal or mediastinal anomalies were detected. Conclusions Overall, our study did not identify a constellation of dysmorphic features in FTGCT individuals, which is consistent with results of genetic studies suggesting that multiple low-penetrance genes are likely responsible for FTGCT susceptibility.

Individuals with obsessive-compulsive features frequently visit dermatologists for complaints of the skin, hair or nails, and often progress towards a chronic relapsing course due to the challenge associated with accurate diagnosis and management of their psychiatric symptoms. The current DSM-5 formally recognizes body dysmorphic disorder, trichotillomania, neurotic excoriation and body focused repetitive behavior disorder as psychodermatological disorders belonging to the category of Obsessive-Compulsive and Related Disorders. However there is evidence that other relevant skin diseases such as delusions of parasitosis, dermatitis artefacta, contamination dermatitis, AIDS phobia, trichotemnomania and even lichen simplex chronicus possess prominent obsessive-compulsive characteristics that do not necessarily fit the full diagnostic criteria of the DSM-5. Therefore, to increase dermatologists' awareness of this unique group of skin disorders with OCD features, we propose a novel classification system called Obsessive-Compulsive Insight Continuum. Under this new classification system, obsessive-compulsive skin manifestations are categorized along a continuum based on degree of insight, from minimal insight with delusional obsessions to good insight with minimal obsessions. Understanding the level of insight is thus an important first step for clinicians who routinely interact with these patients.

Body dysmorphic disorder is common, distressing, and often severely impairing. Serotonin reuptake inhibitors appear efficacious, but the few existing pharmacotherapy studies were short term (≤4 months), and no relapse prevention studies or continuation phase studies have been conducted to the authors' knowledge. The authors report results from the first relapse prevention study in body dysmorphic disorder. Adults (N=100) with DSM-IV body dysmorphic disorder received open-label escitalopram for 14 weeks (phase 1); 58 responders were then randomized to double-blind continuation treatment with escitalopram versus switch to placebo for 6 months (phase 2). Reliable and valid outcome measures were utilized. In phase 1, 67.0% of treated subjects and 81.1% of subjects who completed phase 1 responded to escitalopram. Body dysmorphic disorder severity (in both the intent-to-treat and the completer groups) and insight, depressive symptoms, psychosocial functioning, and quality of life significantly improved from baseline to end of phase 1. In phase 2, time to relapse was significantly longer with escitalopram than with placebo treatment (hazard ratio=2.72, 95% CI=1.01-8.57). Phase 2 relapse proportions were 18% for escitalopram and 40% for placebo. Among escitalopram-treated subjects, body dysmorphic disorder severity significantly decreased over time during the continuation phase, with 35.7% of subjects showing further improvement. There were no significant group differences in body dysmorphic disorder severity or insight, depressive symptoms, psychosocial functioning, or quality of life. Continuation-phase escitalopram delayed time to relapse, and fewer escitalopram-treated subjects relapsed than did placebo-treated subjects. Body dysmorphic disorder severity significantly improved during 6 additional months of escitalopram treatment following acute response; more than one-third of escitalopram-treated subjects experienced further improvement.

Recent data indicate that nuclear lamina (NL) plays a relevant role in many fundamental cellular functions. The peculiar role of NL in cells is dramatically demonstrated by the Hutchinson-Gilford progeria syndrome (HGPS), an inherited laminopathy that causes premature, rapid aging shortly after birth. In HGPS, a mutant form of Lamin A (progeria) leads to a dysmorphic NL structure, but how this perturbation is transduced into cellular changes is still largely unknown. Owing to the close structural relationship between NL and the Nuclear Pore Complex (NPC), in this work we test whether HGPS affects passive and active nucleo-cytoplasmic shuttling of cargoes by means of an established model based of fluorescence recovery after photobleaching. Our findings clearly demonstrate that dysmorphic NL is decoupled from the dynamic characteristics of passive and active transport towards and from the nucleus, as well as from the binding affinity of transport protein mediators.

Suicidality in Body Dysmorphic Disorder

PubMed Central

Phillips, Katharine A.

2008-01-01

Suicidal ideation, suicide attempts, and completed suicide appear common in individuals with body dysmorphic disorder (BDD). Available evidence indicates that approximately 80% of individuals with BDD experience lifetime suicidal ideation and 24% to 28% have attempted suicide. Although data on completed suicide are limited and preliminary, the suicide rate appears markedly high. These findings underscore the importance of recognizing and effectively treating BDD. However, BDD is underrecognized in clinical settings even though it is relatively common and often presents to psychiatrists and other mental health practitioners, dermatologists, surgeons, and other physicians. This article reviews available evidence on suicidality in BDD and discusses how to recognize and diagnose this often secret disorder. Efficacious treatments for BDD, ie, serotonin reuptake inhibitors (SRIs) and cognitive-behavioral therapy, are also discussed. Although data are limited, it appears that SRIs often diminish suicidality in these patients. Additional research is greatly needed on suicidality rates, characteristics, correlates, risk factors, treatment, and prevention of suicidality in BDD. PMID:18449358

Background Anorexia nervosa (AN) and body dysmorphic disorder (BDD) frequently co-occur, and have several overlapping phenomenological features. Little is known about their shared neurobiology. Aims To compare modular organization of brain structural connectivity. Methods We acquired diffusion-weighted magnetic resonance imaging data on unmedicated individuals with BDD (n=29), weight-restored AN (n=24), and healthy controls (HC) (n=31). We constructed connectivity matrices using whole-brain white matter tractography, and compared modular structures across groups. Results AN showed abnormal modularity involving frontal, basal ganglia, and posterior cingulate nodes. There was a trend in BDD for similar abnormalities, but no significant differences compared with AN. In AN, poor insight correlated with longer path length in right caudal anterior cingulate and right posterior cingulate. Conclusions Abnormal network organization patterns in AN, partially shared with BDD, may have implications for understanding integration between reward and habit/ritual formation, as well as conflict monitoring/error detection.

2001-02-01

We report on a consanguineous family with 6 children (out of 7) affected by a spondylo-ocular syndrome. Clinical features include cataract, loss of vision due to retinal detachment, facial dysmorphism, facial hypotonia, normal height with disproportional short trunk, immobile spine with thorakal kyphosis and reduced lumbal lordosis. On ophthalmological examination of the index patient, a dense cataract and complete retinal detachment could be detected on the right eye. On the left eye, an absent lens nucleus was found, but no retinal detachment. On radiological examination, there was generalized moderate osteoporosis; the spine showed marked platyspondyly and the bone age was advanced. On laboratory investigations, a normal excretion of amino acids, mucopolysaccharides and oligosaccharides could be found. The phenotypical spectrum observed in the 6 affected individuals was rather uniform. The karyotype was normal in all affected children. This hitherto undescribed combination of oculo-skeletal symptoms shows most resemblance with connective tissue disorders, suggesting a range of candidate genes for mutation analysis.

Potential link between body dysmorphic disorder symptoms and alexithymia in an eating-disordered treatment-seeking sample.

Fenwick, Andrea Siân; Sullivan, Karen Anne

2011-09-30

This study aimed to explore the manifestation of body dysmorphic disorder symptoms in a sample of people with eating disorders and to investigate possible associations between body dysmorphia and alexithymia. Forty patients currently seeking treatment for an eating disorder completed a battery of six measures assessing alexithymia, mood, eating behaviours, weight-related body image, body dysmorphia and non-weight related body image. Significant moderate positive correlations (Pearson's r) between selected variables were found, suggesting that participants with high levels of dysmorphic concern (imagined ugliness) have more difficulty with the affective elements of alexithymia, that is, identifying and describing feelings. When depression, eating attitudes, and weight-related body image concerns were controlled for, significant moderate positive correlations between this alexithymia factor and dysmorphic concerns remained present. An independent-samples t-test between eating-disordered participants with and without symptoms of body dysmorphic disorder (BDD) revealed significant group differences in difficulties identifying feelings. This pattern of results was replicated when the groups were identified on the basis of dysmorphic concerns, as opposed to BDD symptoms. This study highlights the associations between alexithymia and body dysmorphia that have not previously been demonstrated. Copyright © 2011 Elsevier Ltd. All rights reserved.

To describe the prevalence, demographic and clinical characteristics of body dysmorphic disorder (BDD) compared with other psychiatric outpatients with a mood, anxiety or somatoform disorder. Outpatients referred for treatment of a mood, anxiety or somatoform disorder were routinely assessed at intake. A structured interview (MINI-Plus), observer-based and self-rating instruments were administered by an independent assessor. Among our sample of 3798 referred patients, 2947 patients were diagnosed with at least one DSM-IV mood, anxiety or somatoform disorder. Of these patients 1.8% (n = 54) met the diagnostic criteria for BDD. In comparison with other outpatients, patients with BDD were on average younger, less often married and were more often living alone. Highly prevalent comorbid diagnoses were major depression (in 46.3% of cases), social anxiety disorder (in 35.2% of cases) and obsessive-compulsive disorder (OCD) (in 16.7% of cases). Furthermore, patients with BDD had higher scores on the Clinical Global Impression of Severity (CGI-S) as well as lower scores on the Short Form 36 social role functioning. BDD is frequently associated with depression, social phobia and OCD. Patients with BDD have more distress and more impaired interpersonal functioning.

Intellectual disability (ID) has an estimated prevalence of 1.5-2%. In most affected individuals, its genetic basis remains unclear. Whole exome sequencing (WES) studies have identified a multitude of novel causative gene defects and have shown that a large proportion of sporadic ID cases results from de novo mutations. Here, we present two unrelated individuals with similar clinical features and deleterious de novo variants in FBXO11 detected by WES. Individual 1, a 14-year-old boy, has mild ID as well as mild microcephaly, corrected cleft lip and alveolus, hyperkinetic disorder, mild brain atrophy and minor facial dysmorphism. WES detected a heterozygous de novo 1 bp insertion in the splice donor site of exon 3. Individual 2, a 3-year-old boy, showed ID and pre- and postnatal growth retardation, postnatal mild microcephaly, hyperkinetic and restless behaviour, as well as mild dysmorphism. WES detected a heterozygous de novo frameshift mutation. While ten individuals with ID and de novo variants in FBXO11 have been reported as part of larger studies, only one of the reports has some additional clinical data. Interestingly, the latter individual carries the identical mutation as our individual 2 and also displays ID, intrauterine growth retardation, microcephaly, behavioural anomalies, and dysmorphisms. Thus, we confirm deleterious de novo mutations in FBXO11 as a cause of ID and start the delineation of the associated clinical picture which may also comprise postnatal microcephaly or borderline small head size and behavioural anomalies.

Use of the S3 Corridor for Iliosacral Fixation in a Dysmorphic Sacrum: A Case Report.

2017-01-01

The S1 and S2 corridors are the typical osseous pathways for iliosacral screw fixation of posterior pelvic ring fractures. In dysmorphic sacra, the S1 screw trajectory is often different from that in normal sacra. We present a case of iliosacral screw placement in the third sacral segment for fixation of a complex lateral compression type-3 pelvic fracture in a patient with a dysmorphic sacrum. In patients with dysmorphic sacra and unstable posterior pelvic ring fractures or dislocations, the S3 corridor may be a feasible osseous fixation pathway that can be used in a manner equivalent to the S2 corridor in a normal sacrum.

Victimization, social anxiety, and body dysmorphic concerns: appearance-based rejection sensitivity as a mediator.

PubMed

Lavell, Cassie H; Zimmer-Gembeck, Melanie J; Farrell, Lara J; Webb, Haley

2014-09-01

Body dysmorphic disorder (BDD) is characterized by extreme preoccupation with perceived deficits in physical appearance, and sufferers experience severe impairment in functioning. Previous research has indicated that individuals with BDD are high in social anxiety, and often report being the victims of appearance-based teasing. However, there is little research into the possible mechanisms that might explain these relationships. The current study examined appearance-based rejection sensitivity as a mediator between perceived appearance-based victimization, social anxiety, and body dysmorphic symptoms in a sample of 237 Australian undergraduate psychology students. Appearance-based rejection sensitivity fully mediated the relationship between appearance-based victimization and body dysmorphic symptoms, and partially mediated the relationship between social anxiety and body dysmorphic symptoms. Findings suggest that individuals high in social anxiety or those who have a history of more appearance-based victimization may have a bias towards interpreting further appearance-based rejection, which may contribute to extreme appearance concerns such as BDD.

Hong, Kevin; Nezgovorova, Vera; Uzunova, Genoveva; Schlussel, Danya; Hollander, Eric

2018-04-26

Body dysmorphic disorder is a challenging disorder that manifests as erroneously perceived flaws in one's physical appearance and repetitive behaviors in response to appearance concerns. This disorder is also frequently comorbid with other psychiatric disorders, including major depressive disorder and autism spectrum disorder. It is currently understood to arise from a combination of biological, psychological, and environmental factors. Treatment of body dysmorphic disorder typically consists of a combination of pharmacotherapy and cognitive behavioral therapy. However, not all patients respond to treatment, and BDD symptoms remain even in those who do respond. This review outlines current pharmacological and neuromodulation treatments for body dysmorphic disorder, and suggests directions for future studies of novel treatments such as augmentation with atypical antipsychotics and the use of intranasal oxytocin in cases of body dysmorphic disorder that show residual symptomatology even with tailored monotherapy. There is emerging evidence suggesting that non-invasive neurostimulatory techniques, such as repetitive transcranial magnetic stimulation, may be of value in treatment-resistant cases.

Prazeres, Angélica M; Nascimento, Antônio L; Fontenelle, Leonardo F

2013-01-01

The aim of this study was to review the efficacy of different methods of cognitive and/or behavioral therapies used to treat body dysmorphic disorder. We evaluated all case series, open studies, controlled trials, and meta-analyses of cognitive and/or behavioral treatment approaches to body dysmorphic disorder published up to July 2012, identified through a search in the PubMed/Medline, PsycINFO, ISI Web of Knowledge, and Scopus databases. Our findings indicate that individual and group cognitive behavioral therapies are superior to waiting list for the treatment of body dysmorphic disorder. While the efficacy of cognitive therapy is supported by one controlled trial, utility of behavioral therapy is suggested by one open study and one controlled relapse prevention follow-up study. There is a pressing need to conduct head-to-head studies, with appropriate, active, control treatment groups, in order to examine further the efficacy of cognitive and/or behavioral therapies for body dysmorphic disorder.

Phillips, Katharine A.

2006-01-01

Objective Although body dysmorphic disorder often responds to serotonin reuptake inhibitors (SRIs), most patients do not respond or respond only partially. However, placebo-controlled studies of augmentation of SRIs have not been done. Furthermore, although 40%–50% of patients are delusional, studies of antipsychotic medications have not been done. Method Twenty-eight patients with body dysmorphic disorder or its delusional variant participated in an 8-week, placebo-controlled, double-blind, parallel-group study of pimozide augmentation of fluoxetine. Results Pimozide was not more effective than placebo: two (18.2%) of 11 subjects responded to pimozide and three (17.6%) of 17 subjects responded to placebo. There was no significant effect of baseline delusionality on endpoint severity of body dysmorphic disorder. Delusionality did not decrease significantly more with pimozide than placebo. Conclusions Pimozide augmentation of fluoxetine treatment for body dysmorphic disorder was not more effective than placebo, even in more delusional patients. Further studies of augmentation for SRIs are needed. PMID:15677604

Personality traits as vulnerability factors in body dysmorphic disorder.

Schieber, Katharina; Kollei, Ines; de Zwaan, Martina; Müller, Astrid; Martin, Alexandra

2013-11-30

Cognitive behavioural models consider certain personality traits to be risk factors for the development of Body Dysmorphic Disorder (BDD). Research on personality traits in BDD is scarce, therefore this study examined perfectionism, aesthetic sensitivity and the behavioural inhibition system (BIS) in BDD. Furthermore, the association between these personality traits and the extent of dysmorphic concerns was investigated. Individuals with BDD (n=58) and a population based control sample (n=2071), selected from a representative German population survey, completed self-report questionnaires assessing DSM-5 criteria of BDD, dysmorphic concerns, perfectionism, aesthetic sensitivity and BIS-reactivity. Individuals with BDD reported significantly higher degrees of perfectionism as well as of BIS-reactivity compared to the population based control sample, whereas the groups did not differ significantly regarding aesthetic sensitivity. However, for the total sample, each of the personality traits was related dimensionally to dysmorphic concerns. Current BDD models consider perfectionism and aesthetic sensitivity to be vulnerability factors. In addition to these concepts, the present study suggests that BIS-reactivity is related to BDD. Self-reported aesthetic sensitivity was not found to be specifically pronounced in BDD, but along with perfectionism and BIS-reactivity aesthetic sensitivity was generally associated with dysmorphic concerns. © 2013 Elsevier Ireland Ltd.

Body dysmorphic disorder (BDD) is thought to be etiologically related to obsessive-compulsive disorder (OCD) but the available evidence is incomplete. The current study examined the genetic and environmental sources of covariance between body dysmorphic and obsessive-compulsive symptoms in a community sample of adult twins. A total of 2,148 female twins (1,074 pairs) completed valid and reliable measures of body dysmorphic concerns and obsessive-compulsive symptoms. The data were analyzed using bivariate twin modeling methods and the statistical programme Mx. In the best-fitting model, the covariation between body dysmorphic and obsessive-compulsive traits was largely accounted for by genetic influences common to both phenotypes (64%; 95% CI: 0.50-0.80). This genetic overlap was even higher when specific obsessive-compulsive symptom dimensions were considered, with up to 82% of the phenotypic correlation between the obsessing and symmetry/ordering symptom dimensions and dysmorphic concerns being attributable to common genetic factors. Unique environmental factors, although influencing these traits individually, did not substantially contribute to their covariation. The results remained unchanged when excluding individuals reporting an objective medical condition/injury accounting for their concern in physical appearance. The association between body dysmorphic concerns and obsessive-compulsive symptoms is largely explained by shared genetic factors. Environmental risk factors were largely unique to each phenotype. These results support current recommendations to group BDD together with OCD in the same DSM-5 chapter, although comparison with other phenotypes such as somatoform disorders and social phobia is needed.

Smith-Magenis syndrome (SMS) is a clinically recognizable contiguous gene syndrome ascribed to an interstitial deletion in chromosome 17p11.2. Seventy percent of SMS patients have a common deletion interval spanning 3.5 megabases (Mb). Clinical features of SMS include characteristic mild dysmorphic features, ocular anomalies, short stature, brachydactyly, and hypotonia. SMS patients have a unique neurobehavioral phenotype that includes intellectual disability, self-injurious behavior and severe sleep disturbance. Little has been reported in the medical literature about anatomical brain anomalies in patients with SMS. Here we describe two patients with SMS caused by the common deletion in 17p11.2 diagnosed using chromosomal microarray (CMA). Both patients had a typical clinical presentation and abnormal brain magnetic resonance imaging (MRI) findings. One patient had subependymal periventricular gray matter heterotopia, and the second had a thin corpus callosum, a thin brain stem and hypoplasia of the cerebellar vermis. This report discusses the possible abnormal MRI images in SMS and reviews the literature on brain malformations in SMS. Finally, although structural brain malformations in SMS patients are not a common feature, we suggest baseline routine brain imaging in patients with SMS in particular, and in patients with chromosomal microdeletion/microduplication syndromes in general. Structural brain malformations in these patients may affect the decision-making process regarding their management. © 2014 Wiley Periodicals, Inc.

Potocki-Shaffer syndrome (PSS, OMIM #601224) is a rare contiguous gene deletion syndrome caused by haploinsufficiency of genes located on the 11p11.2p12. Affected individuals have a number of characteristic features including multiple exostoses, biparietal foramina, abnormalities of genitourinary system, hypotonia, developmental delay, and intellectual disability. We report here on the first Korean case of an 8-yr-old boy with PSS diagnosed by high resolution microarray. Initial evaluation was done at age 6 months because of a history of developmental delay, hypotonia, and dysmorphic face. Coronal craniosynostosis and enlarged parietal foramina were found on skull radiographs. At age 6 yr, he had severe global developmental delay. Multiple exostoses of long bones were detected during a radiological check-up. Based on the clinical and radiological features, PSS was highly suspected. Subsequently, chromosomal microarray analysis identified an 8.6 Mb deletion at 11p11.2 [arr 11p12p11.2 (Chr11:39,204,770-47,791,278)×1]. The patient continued rehabilitation therapy for profound developmental delay. The progression of multiple exostosis has being monitored. This case confirms and extends data on the genetic basis of PSS. In clinical and radiologic aspect, a patient with multiple exostoses accompanying with syndromic features, including craniofacial abnormalities and mental retardation, the diagnosis of PSS should be considered.

Objective: To evaluate the possibility of transverse sacroiliac screw placement in different segments of the sacrum. Methods: Data of 80 pelvic CT scans (slice thickness ≤1.0 mm) archived in CT department of the Third Hospital of Hebei Medical University from September 2016 to October 2017 were retrospectively collected. Mimics software was used to rebuild the pelvis three-dimensional model. According to whether the sacral 1(S(1)) segment could place the transverse sacroiliac screws or not, all the sacrums were divided into normal group ( n =55) and dysmorphic group ( n =25). Simulation the S(1), sacral 2(S(2)) transverse sacroiliac screw placement in 3-Matic software. Analysis whether there was any difference in maximum diameter and length of S(2) transverse sacroiliac screw between the normal group and the dysmorphic group. The pelvic CT data of the dysmorphic group were measured, and the optimal tilt angle and length of the oblique S(1) screw were obtained. The feasibility of transverse sacroiliac screw insertion in sacral 3(S(3)) segment was evaluated. t -test, rank sum test, and χ(2) test was used to analyze data, respectively. Results: In the dysmorphic group, the largest diameter of the S(1) transverse screw was (4.9±1.6)mm, and the normal group was (13.6±3.6)mm ( t =-15.07, P =0.00). In the dysmorphic group, the largest diameter of S(2) transverse screw was (13.8±3.0)mm, and was (12.4±2.2)mm in the normal group( t =2.11, P =0.04). There was no significant difference in the length of S(2) transverse sacroiliac screw between the two groups ( t =0.47, P =0.64). In the dysmorphic group, the anterior vertebral height of S(1) was (23.1±4.0)mm, which was significantly higher than that of the normal group ((14.1±4.2)mm)( t =9.01, P =0.00). The angle of S(1)S(2) in the dysmorphic group was 10.9°(3.8°, 17.6°), which was significantly larger than that of the normal group (2.0°(1.0°, 2.0°) ( Z =-4.03, P =0.00). In the dysmorphic group, the incline angle of the oblique S(1) sacroiliac screw was (35.6±6.2)°, the anteversion angle was (37.2±4.4)°, and the mean screw length was (90.2±4.7)mm. In the dysmorphic group, the placement rate of S(3) transverse sacroiliac screw was 48.0%, and that of the normal sacral group was 9.1%. Conclusions: There is often dysmorphic in the sacrum in patients with large S(1) anterior vertebral height and S(1)S(2) angle. Sacral dysmorphic patients with posterior pelvic ring injury may be treated with S(1) pedicle oblique sacroiliac screws. S(3) transverse sacroiliac screws should be carefully placed, especially for the absence of sacral dysmorphic in patients.

Occurrence and clinical features of epileptic and non-epileptic paroxysmal events in five children with Pallister–Killian syndrome

2013-01-01

Pallister–Killian syndrome (PKS) is a rare, sporadic genetic disorder caused by tetrasomy 12p mosaicism associated with a supernumerary isochromosome. Craniofacial dysmorphism, learning impairment and seizures are considered characteristic. However, little is known of the seizure and epilepsy patterns seen in PKS. To better define the occurrence and nature of epileptic and non-epileptic paroxysmal events in PKS, we describe our experience with 5 patients and compare their features with data from a larger cohort of PKS patients ascertained via a web-based parental questionnaire. Three of the 5 patients have had definite epileptic seizures, and one other has had paroxysmal events as yet not clarified. Four of the 5 have also had either non-epileptic paroxysmal events or episodes of uncertain nature. In those with epilepsy, all have had some period of relatively refractory seizures, all have required more than one antiepileptic drug, but none experienced status epilepticus. Only one of the patients with epilepsy (the oldest) has gone into remission. In two of the four with non-epileptic events, video-electroencephalographic monitoring has been valuable in clarifying the nature of the events. EEG characteristics include a slow dominant frequency as well as generalized and focal epileptiform features. Brain MRI findings can be normal but are variable. These specific findings correspond well to information reported by parents in a larger cohort of 51 individuals with PKS. Better understanding of the nature of epileptic and non-epileptic events in PKS will result from a more detailed analysis of objective data obtained from this larger cohort, and from deeper understanding of the molecular impact of 12p tetrasomy in selected cell lines.

In the background, cow’s milk allergy was found, but her body weight was unchanged after eliminating milk from her diet. Other types of malabsorption were excluded. Based on nasal regurgitation and facial dysmorphisms, the possibility of DiGeorge syndrome was suspected and was confirmed by fluorescence in situ hybridization. The authors suggest a new feature associated with DiGeorge syndrome. PMID:19294771

In patients seeking aesthetic rhinoplasty, a high prevalence of body dysmorphic disorder symptoms has recently been reported. However, the impact of these symptoms on the outcomes after rhinoplasty remains elusive. This large-scale study determines the influence of preoperative body dysmorphic disorder symptoms on patients' postoperative satisfaction and quality of life, using validated questionnaires. A 1-year prospective study of 166 adult patients undergoing cosmetic rhinoplasty in a tertiary referral center was performed. Severity of body dysmorphic disorder symptoms was assessed by the modified Yale-Brown Obsessive Compulsive Scale. Postoperative satisfaction was evaluated using a visual analog scale for patients' appraisal of nasal shape and the Rhinoplasty Outcome Evaluation. Generic quality of life was quantified by the Sheehan Disability Scale, whereas the appearance-related disruption of everyday life was measured by the Derriford Appearance Scale-59. Preoperative body dysmorphic disorder symptom scores inversely correlated with postoperative satisfaction at 3 months (visual analog scale nasal shape: rho = -0.43, p < 0.001; Rhinoplasty Outcome Evaluation: rho = -0.48, p < 0.001) and 12 months (rho = -0.40, p < 0.001; and rho = -0.41, p < 0.001, respectively) after surgery. In addition, body dysmorphic disorder symptom scores positively correlated with Sheehan Disability Scale scores and Derriford Appearance Scale-59 scores at 3 months (rho = 0.43, p < 0.001 and rho = 0.48, p < 0.001, respectively) and 12 months (rho = 0.32, p < 0.001, and rho = 0.48, p < 0.001, respectively) postoperatively. This study provides the first evidence of the negative impact of preoperative body dysmorphic disorder symptoms on subjective outcomes after rhinoplasty, hence unveiling a crucial factor in patient dissatisfaction after aesthetic rhinoplasty.

To evaluate the accuracy of computer-assisted sacral screw fixation compared with conventional techniques in the dysmorphic versus normal sacrum. Review of a previous study database. Database of a multinational study with 9 participating trauma centers. The reviewed group included 130 patients, 72 from the navigated group and 58 from the conventional group. Of these, 109 were in the nondysmorphic group and 21 in the dysmorphic group. Placement of sacroiliac (SI) screws was performed using standard fluoroscopy for the conventional group and BrainLAB navigation software with either 2-dimensional or 3-dimensional (3D) navigation for the navigated group. Accuracy of SI screw placement by 2-dimensional and 3D navigation versus conventional fluoroscopy in dysmorphic and nondysmorphic patients, as evaluated by 6 observers using postoperative computerized tomography imaging at least 1 year after initial surgery. Intraobserver agreement was also evaluated. There were 11.9% (13/109) of patients with misplaced screws in the nondysmorphic group and 28.6% (6/21) of patients with misplaced screws in the dysmorphic group, none of which were in the 3D navigation group. Raw agreement between the 6 observers regarding misplaced screws was 32%. However, the percent overall agreement was 69.0% (kappa = 0.38, P < 0.05). The use of 3D navigation to improve intraoperative imaging for accurate insertion of SI screws is magnified in the dysmorphic proximal sacral segment. We recommend the use of 3D navigation, where available, for insertion of SI screws in patients with normal and dysmorphic proximal sacral segments. Therapeutic level I.

Body dysmorphic disorder (BDD) is a psychosomatic disease associated with reduced quality of life and suicidal ideations. Increasing attention to beauty and the development of beauty industries lead to the hypothesis that BDD is increasing. The aim of this study was to test this hypothesis in two representative samples of Germans, assessed in 2002 and 2013. In 2002, n = 2,066 and in 2013, n = 2,508 Germans were asked to fill in the Dysmorphic Concern Questionnaire (DCQ), which assesses dysmorphic concerns. Subclinical and clinical dysmorphic concerns increased from 2002 to 2013 (subclinical from 0.5% to 2.6%, OR = 5.16 (CI95% = 2.64; 10.06); clinical from 0.5% to 1.0%, OR = 2.20 (CI95% = 1.03; 4.73). Women reported more dysmorphic concerns than men, with rates of 0.7% subclinical and 0.8 clinical BDD in women and 0.3% subclinical and 0.1% clinical BDD in men in 2002. In 2013, 2.8% subclinical and 1.2% clinical BDD were found in women and 2.4% subclinical and 0.8% clinical BDD in men. Further studies should assess predictors for developing a BDD and evaluate factors determining the efficacy of disease-specific psychotherapeutic and psychotropic drug treatments.

Biallelic UNC80 mutations cause infantile hypotonia with psychomotor retardation and characteristic facies 2 (IHPRF2), which is characterized by hypotonia, developmental delay (DD)/intellectual disability (ID), intrauterine growth retardation, postnatal growth retardation and characteristic facial features. We report two unrelated Chinese patients with compound heterozygous UNC80 mutations inherited from their parents, as identified by whole-exome sequencing (WES). Mutations c.3719G>A (p.W1240*)/c.4926_4937del (p.N1643_L1646del) and c.4963C>T (p.R1655C)/c.8385C>G (p.Y2795*) were identified in patient 1 and patient 2, respectively. Although both patients presented with DD/ID and hypotonia, different manifestations also occurred. Patient 1 presented with infantile hypotonia, epilepsy and hyperactivity without growth retardation, whereas patient 2 presented with persistent hypotonia, growth retardation and self-injury without epilepsy. Furthermore, we herein summarize the genotypes and phenotypes of patients with UNC80 mutations reported in the literature, revealing that IHPRF2 is a phenotypically heterogeneous disease. Common facial dysmorphisms include a thin upper lip, a tented upper lip, a triangular face, strabismus and microcephaly. To some extent, the manifestations of IHPRF2 mimic those of Angelman syndrome (AS)-like syndromes. Copyright © 2018 Elsevier B.V. All rights reserved.

Our objective is to report the prevalence and the clinical features associated with body dysmorphic disorder (BDD) and eating disorders (ED) in a group of elite Brazilian professional female ballet dancers. Thirty-five elite Brazilian professional female ballet dancers were invited to participate in the study and 19 agreed to be assessed. Individuals were evaluated with a series of instruments, including the Mini International Neuropsychiatric Interview supplemented by the somatoform and eating disorders modules of the Structured Clinical Interview for DSM-IV disorders, the Bulimic Investigatory Test, and the Beck Depression Inventory. Three dancers (15.78%) had a lifetime diagnosis of anorexia nervosa (restrictive subtype) and 2 others (10.52%) presented a current diagnosis of BDD. No individuals had current or lifetime bulimia nervosa. Results could not be ascribed to comorbid major depression or increased severity of depression. The lifetime prevalence of BDD and ED among elite professional female ballet dancers was higher than the general population. High standards of beauty, public body exposure, and repeated exposure to mirrors in the rehearsal rooms may contribute to the development of body image disorders in this sample.

Phenotype of a child with Angelman syndrome born to a woman with Prader-Willi syndrome.

Ostergaard, John R

2015-09-01

This report describes the phenotype, from early childhood to adolescence, of a girl with Angelman syndrome (AS) born following a maternal transmission of a germline paternal 15q11.2-q13 deletion. During early childhood, she showed a typical AS phenotype, such as jerky movements, poor sleep, high voltage electroencephalography pattern, epilepsy, and a severe developmental disability. As she grew older, indications of phenotypical traits similar to Prader-Willi syndrome (PWS) appeared, in particular hyperphagic behavior and a body fat distribution similar to that reported in PWS. She generally showed cheerful AS behavior and had the characteristic outbursts of laughter, but her attitude to other people did not reflect the usual shared enjoyment of interaction seen in children with AS. In unfamiliar surroundings, she withdrew socially, similar to children with PWS, and her insistence on the same, rigid routines was similar to behavior patterns in PWS. The dysmorphic facial features that characterize AS were blurred in adolescence. The specified features that this AS patient had in common with PWS were hardly incidental and, if verified by upcoming case reports of children born to women with a paternal 15q11.2-q13 deletion, they may show new aspects of genetic imprinting. © 2015 Wiley Periodicals, Inc.

Gorlin-Goltz syndrome is a rare hereditary disease that can have negative effects on one's quality of life. The main clinical features are multiple nevoid basal cell carcinomas, odontogenic keratocysts, congenital skeletal abnormalities, calcification of the falx cerebri, facial dysmorphism, and skin depressions (pits) on the palms and soles. Diagnosis is based on major and minor clinical and radiological criteria and can be confirmed by DNA analysis. This article describes the case of a child with Gorlin-Goltz syndrome and outlines the clinical manifestations of the disease.

Histopathological investigations showed abnormalities of the metaphyseal cartilage and adjacent diaphyseal ossification, excessive modelling of the metaphyses, and, in one case, dysplasia of the epiphyseal cartilage. We review three previously reported cases. We suggest the name osteocraniostenosis to describe this radiological and clinical disorder, pinpointing its major clinical and radiological features.

Chromosome 16 contains multiple copy number variations (CNVs) that predispose to genomic disorders. Here, we differentiate pathogenic duplications of 16p11.2–p12.2 from microscopically similar euchromatic variants of 16p11.2. Patient 1 was a girl of 18 with autism, moderate intellectual disability, behavioural difficulties, dysmorphic features and a 7.71-Mb (megabase pair) duplication (16:21 521 005–29 233 146). Patient 2 had a 7.81-Mb duplication (16:21 382 561–29 191 527), speech delay and obsessional behaviour as a boy and, as an adult, short stature, macrocephaly and mild dysmorphism. The duplications contain 65 coding genes of which Polo-like kinase 1 (PLK1) has the highest likelihood of being haploinsufficient and, by implication, a triplosensitive gene. An additional 1.11-Mb CNV of 10q11.21 in Patient 1 was a possible modifier containing the G-protein-regulated inducer of neurite growth 2 (GPRIN2) gene. In contrast, the euchromatic variants in Patients 3 and 4 were amplifications from a 945-kb region containing non-functional immunoglobulin heavy chain (IGHV), hect domain pseudogene (HERC2P4) and TP53-inducible target gene 3 (TP53TG3) loci in proximal 16p11.2 (16:31 953 353–32 898 635). Paralogous pyrosequencing gave a total copy number of 3–8 in controls and 8 to >10 in Patients 3 and 4. The 16p11.2–p12.2 duplication syndrome is a recurrent genomic disorder with a variable phenotype including developmental delay, dysmorphic features, mild to severe intellectual disability, autism, obsessive or stereotyped behaviour, short stature and anomalies of the hands and fingers. It is important to differentiate pathogenic 16p11.2–p12.2 duplications from harmless, microscopically similar euchromatic variants of proximal 16p11.2, especially at prenatal diagnosis.

Body dysmorphic disorder is a chronic psychiatric disorder characterized by excessive preoccupation with an absent or minimal physical deformity. It causes severe distress and impairs normal functioning. In the last centuries, this disorder has been mentioned in the medical literature by important mental health practitioners by different names, such as "dysmorphophobia" or "dermatologic hypochondriasis". However, not until the last century was it included among the obsessive-compulsive disorders, although its classification has changed over time.Patients with body dysmorphic disorder constantly seek cosmetic treatments in order to improve their physical appearance, which more often deteriorates their mental condition. The high prevalence of psychiatric disorders in cosmetic medical practice has led in this field of study to the new science "cosmetic psychodermatology". This paper presents a summary of important facts about body dysmorphic disorder and its description throughout the history of medicine.

Between 0.8 and 1.8 % of the German population suffers from a body dysmorphic disorder. In specific settings like dermatological offices up to 11.9 % of patients suffer from this disease. The highest prevalence could be found in the field of cosmetic dermatology with a prevalence of 13.1 %. Until now, the diagnosis has been made too rarely. The body dysmorphic disorder is a chronic psychic disease, in which the patients feel disfigured and experience shame and disgust at the same time. Comorbidities like social phobia, depression, suicidality, and eating disorders are frequent. The diagnosis is made using questionnaires (e.g., dysmorphic concern questionnaire) or by use of the DSM-5 manual. An early diagnosis seems to be important to avoid chronification and suicidal ideas. Therapeutic approaches should include cognitive behavioral therapies as well as the use of SSRIs.

Dysmorphophobia is a psychiatric condition which frequently presents in the clinics of dermatologists and plastic surgeons. This disorder (also called body dysmorphic disorder) is troublesome to the patient whilst being confusing for the doctor. This commonly undiagnosed condition can be detected by a few simple steps. Timely referral to a psychiatrist benefits most patients suffering from it. This article describes with a case vignette, how to recognize body dysmorphic disorder presenting in the dermatological or aesthetic surgery set up. Diagnostic criteria, eitiology, approach to patient, management strategy and when to refer are important learning points. The importance of recognizing this disorder timely and referring the patient to the psychiatrist for appropriate treatment is crucial. This article covers all aspects of body dysmorphic disorder relevant to dermatologists and plastic surgeons and hopes to be useful in a better understanding of this disorder. PMID:26644741

Patients with Williams-Beuren Syndrome can be recognized clinically, given the characteristic dysmorphism, intellectual disability, and behavior. We report on a Congolese boy with typical WBS facial characteristics. He suffered meningitis and coma at the age of 2 years then subsequently presented with profound intellectual disability and atypical behavior. The WBS was only made at age 8.2 years and confirmed with FISH testing and microarray-CGH. The present report aims to warn clinicians that infections may associate and/or modify a genetic disease as this may be observed in developing countries given the prevalence of infectious diseases.

Williams-Beuren syndrome is a rare neurodevelopmental disorder, characterized by congenital heart defects, abnormal facial features, mental retardation with specific cognitive and behavioral profile, growth hormone deficiency, renal and skeletal anomalies, inguinal hernia, infantile hypercalcaemia. We report a case with Williams-Beuren syndrome associated with a single kidney and nephrocalcinosis complicated by hypercalcaemia. A male infant, aged 20 months presented growth retardation associated with a psychomotor impairment, dysmorphic features and nephrocalcinosis. He had also hypercalciuria and hypercalcemia. Echocardiography was normal. DMSA renal scintigraphy showed a single functioning kidney. The FISH generated one ELN signal in 20 metaphases read and found the presence of ELN deletion, with compatible Williams-Beuren syndrome.

This report describes an infant with fatal congenital heart disease, cleft palate, brain malformations, and trisomy 8p resultant from the paternal balanced reciprocal translocation, rcp(8;15) (p11;p11). Review of six previously reported trisomy 8p patients (resultant from parental balanced translocation in each instance) revealed severe mental retardation in five, short stature in all, and a variety of brain, skeletal, and cardiac defects. The features of the seven trisomy 8p patients reviewed here are not sufficiently similar to suggest a distinct dysmorphic syndrome. In addition the features differ from those in the trisomy 8 mosaicism syndrome, in which the mental retardation and malformations are generally less severe.

Chromosome instability syndromes are a group of inherited conditions associated with chromosomal instability and breakage, often leading to immunodeficiency, growth retardation and increased risk of malignancy. We performed exome sequencing on a girl with a suspected chromosome instability syndrome that manifested as growth retardation, microcephaly, developmental delay, dysmorphic features, poikiloderma, immune deficiency with pancytopenia, and myelodysplasia. She was homozygous for a previously reported splice variant, c.4444 + 3A > G in the POLE1 gene, which encodes the catalytic subunit of DNA polymerase E. This is the second family with POLE1-deficency, with the affected individual demonstrating a more severe phenotype than previously described.

Chromosome 2q37 deletion syndrome is a rare chromosomal disorder characterized by mild to moderate developmental delay, brachydactyly of the third to fifth digits or toes, short stature, obesity, hypotonia, a characteristic facial appearance, and autism spectrum disorder. Here, we report on a patient with 2q37 deletion presenting with dilated cardiomyopathy (DCMP). Congenital heart malformations have been noted in up to 20% of patients with 2q37 deletions. However, DCMP has not been reported in 2q37 deletion patients previously. The patient exhibited the characteristic facial appearance (a flat nasal bridge, deep-set eyes, arched eyebrows, and a thin upper lip), developmental delay, mild mental retardation, peripheral nerve palsy, and Albright hereditary osteodystrophy (AHO)-like phenotypes (short stature and brachydactyly). Conventional chromosomal analysis results were normal; however, microarray-based comparative genomic hybridization revealed terminal deletion at 2q37.1q37.3. In addition, the patient was confirmed to have partial growth hormone (GH) deficiency and had shown a significant increase in growth rate after substitutive GH therapy. Chromosome 2q37 deletion syndrome should be considered in the differential diagnosis of patients presenting with AHO features, especially in the presence of facial dysmorphism. When patients are suspected of having a 2q37 deletion, high-resolution cytogenetic analysis is recommended. PMID:28690993

The presence, predictive utility, and clinical significance of body dysmorphic symptoms in women with eating disorders

2013-01-01

Background Both eating disorders (EDs) and body dysmorphic disorder (BDD) are disorders of body image. This study aimed to assess the presence, predictive utility, and impact of clinical features commonly associated with BDD in women with EDs. Methods Participants recruited from two non-clinical cohorts of women, symptomatic and asymptomatic of EDs, completed a survey on ED (EDE-Q) and BDD (BDDE-SR) psychopathology, psychological distress (K-10), and quality of life (SF-12). Results A strong correlation was observed between the total BDDE-SR and the global EDE-Q scores (r = 0.79, p < 0.001). Multivariate analyses demonstrated that participants with probable EDs (n = 61) and BDD (n = 23) scored higher on 28 of the 30 BDDE-SR items compared to healthy controls (n = 173; all p < 0.05), indicating greater severity of BDD symptoms. BDD participants also scored higher than ED participants on 15 of the 30 BDDE-SR items (all p < 0.05). The remaining 15 items that ED and BDD participants scored similarly on (all p > 0.05) measured appearance checking, reassurance-seeking, camouflaging, comparison-making, and social avoidance. In addition to these behaviors, inspection of sensitivity (Se) and specificity (Sp) revealed that BDDE-SR items measuring preoccupation and dissatisfaction with appearance were most predictive of ED cases (Se and Sp > 0.60). Higher total BDDE-SR scores were associated with greater distress on the K-10 and poorer quality of life on the SF-12 (all p < 0.01). Conclusions Clinical features central to the model of BDD are common in, predictive of, and associated with impairment in women with EDs. Practice implications are that these features be included in the assessment and treatment of EDs. PMID:24999401

Phelan-McDermid syndrome is a rare genetic disorder caused by the terminal or interstitial deletion of the chromosome 22q13.3. Patients with this syndrome usually have global developmental delay, hypotonia, and speech delays. Several putative genes such as the SHANK3 , RAB , RABL2B , and IB2 are responsible for the neurological features. This study describes the clinical features and outcomes of Korean patients with Phelan-McDermid syndrome. Two patients showing global developmental delay, hypotonia, and speech delay were diagnosed with Phelan-McDermid syndrome via chromosome analysis, fluorescent in situ hybridization, and multiplex ligation-dependent probe amplification analysis. Brain magnetic resonance imaging of Patients 1 and 2 showed delayed myelination and severe communicating hydrocephalus, respectively. Electroencephalography in patient 2 showed high amplitude spike discharges from the left frontotemporoparietal area, but neither patient developed seizures. Kidney ultrasonography of both the patients revealed multicystic kidney disease and pelviectasis, respectively. Patient 2 experienced recurrent respiratory infections, and chest computed tomography findings demonstrated laryngotracheomalacia and bronchial narrowing. He subsequently died because of heart failure after a ventriculoperitoneal shunt operation at 5 months of age. Patient 1, who is currently 20 months old, has been undergoing rehabilitation therapy. However, global developmental delay was noted, as determines using the Korean Infant and Child Development test, the Denver developmental test, and the Bayley developmental test. This report describes the clinical features, outcomes, and molecular genetic characteristics of two Korean patients with Phelan-McDermid syndrome.

The clinical use of array comparative genomic hybridization in the evaluation of patients with multiple congenital anomalies and/or mental retardation has recently led to the discovery of a number of novel microdeletion and microduplication syndromes. We present four male patients with overlapping molecularly defined de novo microdeletions of 16q24.3. The clinical features observed in these patients include facial dysmorphisms comprising prominent forehead, large ears, smooth philtrum, pointed chin and wide mouth, variable cognitive impairment, autism spectrum disorder, structural anomalies of the brain, seizures and neonatal thrombocytopenia. Although deletions vary in size, the common region of overlap is only 90 kb and comprises two known genes, Ankyrin Repeat Domain 11 (ANKRD11) (MIM 611192) and Zinc Finger 778 (ZNF778), and is located approximately 10 kb distally to Cadherin 15 (CDH15) (MIM 114019). This region is not found as a copy number variation in controls. We propose that these patients represent a novel and distinctive microdeletion syndrome, characterized by autism spectrum disorder, variable cognitive impairment, facial dysmorphisms and brain abnormalities. We suggest that haploinsufficiency of ANKRD11 and/or ZNF778 contribute to this phenotype and speculate that further investigation of non-deletion patients who have features suggestive of this 16q24.3 microdeletion syndrome might uncover other mutations in one or both of these genes.

We report 3 year old male, referred for evaluation of developmental delays. Pregnancy was complicated by oligohydramnios, proteinuria and prematurity. Medical history revealed: bilateral inguinal hernia, small scrotal sac, undescended testes, developmental delays and behavioral problems. The child had: microcephaly, facial dysmorphic features, single palmar creases, hypopigmented skin lesions of variable size, intermittent exotropia and small retracted testes. Neurological examination was normal. Cognitive level was at the average range with mild delay in his adaptive behavior. Expressive language delays and severe articulation disorder were noted, as well as clumsiness, poor control and precision of gross and fine motor skills. Chromosomalmore » analysis of peripheral leukocytes indicated that one of the number 11 chromosomes had undergone a pericentric inversion with breakpoints on the short (p) arm at band p14.3 and the long (q) arm at band q21. An MRI of the brain showed mild delay in myelinization pattern of white matter. Chromosome 11 inversion in other sites was associated with Beckwith-Wiedemann syndrome and several malignancies. To our knowledge this is the first description of inv(11)(p14.3q21) that is associated with microcephaly, dysmorphic features, hypopigmented skin lesions and speech delay. This inversion may disrupt the expression of the involved genes. However, additional cases with the same cytogenetic anomaly are needed to explore the phenotypic significance of this disorder.« less

Abnormalities of Object Visual Processing in Body Dysmorphic Disorder

Feusner, Jamie D.; Hembacher, Emily; Moller, Hayley; Moody, Teena D.

2013-01-01

Background Individuals with body dysmorphic disorder may have perceptual distortions for their appearance. Previous studies suggest imbalances in detailed relative to configural/holistic visual processing when viewing faces. No study has investigated the neural correlates of processing non-symptom-related stimuli. The objective of this study was to determine whether individuals with body dysmorphic disorder have abnormal patterns of brain activation when viewing non-face/non-body object stimuli. Methods Fourteen medication-free participants with DSM-IV body dysmorphic disorder and 14 healthy controls participated. We performed functional magnetic resonance imaging while participants matched photographs of houses that were unaltered, contained only high spatial frequency (high detail) information, or only low spatial frequency (low detail) information. The primary outcome was group differences in blood oxygen level-dependent signal changes. Results The body dysmorphic disorder group showed lesser activity in the parahippocampal gyrus, lingual gyrus, and precuneus for low spatial frequency images. There were greater activations in medial prefrontal regions for high spatial frequency images, although no significant differences when compared to a low-level baseline. Greater symptom severity was associated with lesser activity in dorsal occipital cortex and ventrolateral prefrontal cortex for normal and high spatial frequency images. Conclusions Individuals with body dysmorphic disorder have abnormal brain activation patterns when viewing objects. Hypoactivity in visual association areas for configural and holistic (low detail) elements and abnormal allocation of prefrontal systems for details is consistent with a model of imbalances in global vs. local processing. This may occur not only for appearance but also for general stimuli unrelated to their symptoms. PMID:21557897

Consanguinity and dysmorphology in Arabs.

PubMed

Al-Gazali, Lihadh; Hamamy, Hanan

2014-01-01

Incidence rates of congenital disorders among the 350 million inhabitants of Arab countries could be influenced via the people's demographic and cultural characteristics. Arabs usually marry at a young age and have large families. They share certain core cultural values and beliefs, with the family accepted as the central structure of society. Consanguineous marriage is favored and respected in most if not all Arab communities, and intrafamilial unions currently account for 20-50% of all marriages. First-cousin unions are especially popular and constitute almost one quarter of all marriages in many Arab countries. Consequently, autosomal recessive (AR) dysmorphic syndromes constitute a considerable proportion of all birth defects among Arabs. Arab geneticists, with their persistent commitment to advancing research, have contributed to the description of a number of rare and new AR syndromes with the identification of novel genes. The collaboration with research teams in high-income countries resulted in a plethora of data on pathogenic variants and their function in causing dysmorphic syndromes. There could still be a considerable number of rare dysmorphic syndromes that prevail among Arabs which are not hitherto described and whose underlying molecular pathologies are not yet defined. Arab countries should thus strive to deploy DNA diagnostics and to build research capability around local priorities. Furthermore, a characterization of the prevailing genetic disorders in each geographic location, together with their mutations, is needed to plan for appropriate screening and testing protocols. An overview of consanguinity in Arab countries and examples of dysmorphology syndromes associated with consanguinity with their available molecular bases will be discussed. © 2014 S.

Monosomy 1p36 is a clinically recognizable syndrome that is considered to be the most common terminal deletion syndrome. It has characteristic clinical features that include craniofacial dysmorphism, congenital anomalies, hearing deficits, developmental delay, mental retardation, hypotonia, seizures, and brain anomalies. Brain anomalies in patients with 1p36 deletion are frequent but inconsistent. To date, 2 cases with monosomy 1p36 associated with periventricular nodular heterotopia (PNH) have been reported. We report a 2-month-old boy with multiple congenital anomalies; brain magnetic resonance imaging revealed PNH. The first 2 described cases were pure terminal deletions, whereas our patient carried unbalanced translocation due to an adjacent 1 segregation of a balanced maternal translocation, resulting in monosomy 1p36.3 and trisomy 19p13.3 identified by whole-genome array comparative genomic hybridization analysis. Our patient, with a smaller deletion that the 2 previously reported cases, can help narrow the critical region for PNH in association with the 1p36 deletion. Several potential candidate genes are discussed. Copyright © 2011 Elsevier Inc. All rights reserved.

Obsessive-compulsive spectrum disorders

The obsessive-compulsive spectrum is an important concept referring to a number of disorders drawn from several diagnostic categories that share core obsessive-compulsive features. These disorders can be grouped by the focus of their symptoms: bodily preoccupation, impulse control, or neurological disorders. Although the disorders are clearly distinct from one another, they have intriguing similarities in phenomenology, etiology, pathophysiology, patient characteristics, and treatment response. In combination with the knowledge gained through many years of research on obsessive-compulsive disorder (OCD), the concept of a spectrum has generated much fruitful research on the spectrum disorders. It has become apparent that these disorders can also be viewed as being on a continuum of compulsivity to impulsivity, characterized by harm avoidance at the compulsive end and risk seeking at the impulsive end. The compulsive and impulsive disorders differ in systematic ways that are just beginning to be understood. Here, we review these concepts and several representative obsessive-compulsive spectrum disorders including both compulsive and impulsive disorders, as well as the three different symptom clusters: OCD, body dysmorphic disorder, pathological gambling, sexual compulsivity, and autism spectrum disorders.

Baraitser-Winter syndrome (BRWS) is a rare condition affecting the development of the brain and the face. The most common characteristics are unusual facial appearance including hypertelorism and ptosis, ocular colobomas, hearing loss, impaired neuronal migration and intellectual disability. BRWS is caused by mutations in the ACTB and ACTG1 genes. Cerebro-fronto-facial syndrome (CFFS) is a clinically heterogeneous condition with distinct facial dysmorphism, and brain abnormalities. Three subtypes are identified. We report a female infant with striking facial features and brain anomalies (included polymicrogyria) that fit into the spectrum of the CFFS type 3 (CFFS3). She also had minor anomalies on her hands and feet, heart and kidney malformations, and recurrent infections. DNA investigations revealed c.586C>T mutation (p.Arg196Cys) in ACTB. This mutation places this patient in the spectrum of BRWS. The same mutation has been detected in a polymicrogyric patient reported previously in literature. We expand the malformation spectrum of BRWS/CFFS3, and present preliminary findings for phenotype-genotype correlation in this spectrum. Copyright © 2013 Elsevier Masson SAS. All rights reserved.

Cerebro-facio-thoracic dysplasia (Pascual-Castroviejo syndrome): Identification of a novel mutation, use of facial recognition analysis, and review of the literature.

Tender, Jennifer A F; Ferreira, Carlos R

2018-04-13

Cerebro-facio-thoracic dysplasia (CFTD) is a rare, autosomal recessive disorder characterized by facial dysmorphism, cognitive impairment and distinct skeletal anomalies and has been linked to the TMCO1 defect syndrome. To describe two siblings with features consistent with CFTD with a novel homozygous p.Arg114* pathogenic variant in the TMCO1 gene. We conducted a literature review and summarized the clinical features and laboratory results of two siblings with a novel pathogenic variant in the TMCO1 gene. Facial recognition analysis was utilized to assess the specificity of facial traits. The novel homozygous p.Arg114* pathogenic variant in the TMCO1 gene is responsible for the clinical features of CFTD in two siblings. Facial recognition analysis allows unambiguous distinction of this syndrome against controls.

Urinary sediment is used to evaluate patients with possible urinary tract diseases. Currently, numerous protocols are applied to detect dysmorphic red blood cells (RBCs) and renal tubular epithelial cells (RTECs) in urinary sediment. However, distinct protocols are used by nephrologists and medical technologists for specimen concentration and observation, which leads to major discrepancies in the differential counts of formed elements such as dysmorphic RBCs and RTECs and might interfere with an accurate clinical diagnosis. To resolve these problems, we first tested a modified urinalysis protocol with an increased relative centrifuge force and concentration factor in 20 biopsy-confirmed glomerulonephritis patients with haematuria. We successfully improved the recovery ratio of dysmorphic RBCs in clinical specimens from 34.7% to 42.0% (P < 0.001). Furthermore, we confirmed the correlation between counts by the modified urinary protocol and Sysmex UF-1000i urinary flow cytometer (r ≥ 0.898, P < 0.001). A total of 28 types of isomorphic and dysmorphic RBCs were detected using a bright field microscope, with results comparable to those using a standard phase contrast microscope. Finally, we applied Sternheimer stain to enhance the contrast of RTECs in the urinary sediments. We concluded that this modified urinalysis protocol significantly enhanced the quality of urinalysis.

Ribeiro, Rafael Vilela Eiras

2017-08-01

The aim of the present study was to evaluate the prevalence of body dysmorphic disorder in plastic surgery and dermatology patients, by performing a systematic review of the literature and meta-analysis. The most relevant studies published originally in any language were analyzed. The literature search was performed using the PubMed, Cochrane Central Register of Controlled Trials (CENTRAL), and Scielo databases. The final sample comprised 33 publications that were submitted to meta-analysis. The study verified that 15.04% of plastic surgery patients had body dysmorphic disorder (range 2.21-56.67%); patient mean age was 34.54 ± 12.41 years, and most were women (74.38%). Among dermatology patients, 12.65% (range 4.52-35.16%) had body dysmorphic disorder; patient mean age was 27.79 ± 9.03 years, and most were women (76.09%). Both plastic surgeons and dermatologists must adequately assess their patients to identify those with a higher likelihood of body dysmorphic disorder and should arrange multidisciplinary care for such individuals.

The rearrangements of the 22q11.2 chromosomal region, most frequently deletions and duplications, have been known to be responsible for multiple congenital anomaly disorders. These rearrangements are implicated in syndromes that have some phenotypic resemblances. While the 22q11.2 deletion, also known as DiGeorge/Velocardiofacial syndrome, has common features that include cardiac abnormalities, thymic hypoplasia, characteristic face, hypocalcemia, cognitive delay, palatal defects, velopharyngeal insufficiency, and other malformations, the microduplication syndrome is largely undetected. This is mainly because phenotypic appearance is variable, milder, less characteristic and unpredictable. In this paper, we report the clinical evaluation and follow-up of two patients affected by 22q11.2 rearrangements, emphasizing new phenotypic features associated with duplication and triplication of this genomic region. Patient 1 is a 24 year-old female with 22q11.2 duplication who has a heart defect (ostium secundum atrial septal defect) and supernumerary teeth (hyperdontia), a feature previously not reported in patients with 22q11.2 microduplication syndrome. Her monozygotic twin sister, who died at the age of one month, had a different heart defect (truncus arteriousus). Patient 2 is a 20 year-old female with a 22q11.2 triplication who had a father with 22q11.2 duplication. In comparison to the first case reported in the literature, she has an aggravated phenotype characterized by heart defects (restrictive VSD and membranous subaortic stenosis), and presented other facial dysmorphisms and urogenital malformations (ovarian cyst). Additionally, she has a hemangioma planum on the right side of her face, a feature of Sturge-Weber syndrome. In this report, we described hyperdontia as a new feature of 22q11.2 microdeletion syndrome. Moreover, this syndrome was diagnosed in a patient who had a deceased monozygotic twin affected with a different heart defect, which corresponds to a phenotypic discordance never reported in the literature. Case 2 is the second clinical report of 22q11.2 triplication and presents an aggravated phenotype in contrast to the patient previously reported.

Men with body dysmorphic disorder (BDD) may be preoccupied with the size or shape of the penis, which may be causing significant shame or impairment. Little is known about the characteristics and phenomenology of such men and whether they can be differentiated from men with small penis anxiety (SPA) (who do not have BDD), and men with no penile concerns. Twenty-six men with BDD, 31 men with SPA, and 33 men without penile concerns were compared on psychopathology, experiences of recurrent imagery, avoidance and safety-seeking behaviours. Men with BDD had significantly higher scores than both the SPA group and no penile concern group for measures of imagery, avoidance, safety seeking and general psychopathology. The groups differed on the phenomenology of BDD specific to penile size preoccupation clearly from the worries of SPA, which in turn were different to those of the men without concerns. The common avoidance and safety seeking behaviours were identified in such men that may be used clinically. Copyright © 2014 Elsevier Ltd. All rights reserved.

To investigate the relationship between body dysmorphic syndrome and self-esteem in rhinoplasty candidates. A negative statistical correlation was evident between Rosenberg Self-Esteem Scale (RSES) and Body Dysmorphic Disorder Examination-Self Report (BDDE-SR) scores. In terms of responses to the first Body Dysmorphic Disorder Questionnaire (BDDQ) question, which focuses on general attitude toward body dysmorphic syndrome, the average RSES "YES" score was significantly less than the "NO" score. No significant differences appeared between RSES scores and scores for the 4th subgroup of BDDQ questions (subgroups A, B, and C; these questions explore how much time is spent daily on maintenance of bodily appearance). However, significant differences appeared between scores for the 4th subgroup of BDDQ questions and BDDE-SR scores. The average BDD-SR score of subgroup A (less than 1 hour spent on bodily maintenance) was significantly lower than those of group B (1-3 hours) and group C (more than 3 hours). However, no significant differences appeared in average BDD-SR scores between subgroups B and C. In this prospective study, 56 patients (31 females and 25 males) were evaluated preoperatively using the BDDQ, the BDDE-SR, and the RSES. Patients younger than 15 years and those with deformities caused by trauma were excluded. Rhinoplasty candidates had higher levels of body dysmorphic disorder (BDD). Although patients with low RSES scores were more likely to have BDD, rhinoplasty candidates were not notably deficient in self-esteem. However, in rhinoplasty candidates with low RSES scores, the frequency of BDD was elevated. Therefore, the authors suggest that rhinoplasty candidates with low RSES scores should be investigated carefully in terms of BDD.

Body dysmorphic disorder: prevalence and outcomes in an oculofacial plastic surgery practice.

To determine the prevalence, associated factors, and surgical outcomes of patients with body dysmorphic disorder in an oculofacial surgery practice. Retrospective cross-sectional analysis of a consecutive case series. Participants consisted of a consecutive series of 728 patients who completed the Dysmorphic Concern Questionnaire in an oculofacial surgery practice at The Cole Eye Institute between November 2013 and June 2014. A questionnaire score ≥9 was used as a positive screen for body dysmorphic disorder. Three control patients scoring ≤8 in the same month were randomly selected for each positive-screening patient. Main outcome measures included number of reoperations, surgical complications, and follow-up visits; preoperative and postoperative pain scores; and the technician word count. Categorical variables were analyzed with Pearson χ(2) tests or Fisher exact tests, while continuous variables were analyzed with Wilcoxon rank sum tests or t tests. A total of 728 patients completed the questionnaire and 50 (6.9%) scored 9 or more. Using a confidence interval of 95%, patients in the positive questionnaire screen group were younger (P = .004), had more eyelid surgeries (P = .007), experienced higher rates of complications after surgery (P = .002), reported higher postoperative pain scores (P = .034), required more reoperations (P = .050), and had a higher technician word count compared to the control group (P = .003). The prevalence of body dysmorphic disorder in an oculofacial surgical setting matches reports from other surgical specialties, and is significantly higher than in the general population. Patients screening positively for body dysmorphic disorder tend to have higher postoperative pain scores and more postoperative complications. Copyright © 2015 Elsevier Inc. All rights reserved.

The cutis laxa syndromes are multisystem disorders that share loose redundant inelastic and wrinkled skin as a common hallmark clinical feature. The underlying molecular defects are heterogeneous and 13 different genes have been involved until now, all of them being implicated in elastic fiber assembly. We provide here molecular and clinical characterization of three unrelated patients with a very rare phenotype associating cutis laxa, facial dysmorphism, severe growth retardation, hyperostotic skeletal dysplasia, and intellectual disability. This disorder called Lenz-Majewski syndrome (LMS) is associated with gain of function mutations in PTDSS1, encoding an enzyme involved in phospholipid biosynthesis. This report illustrates that LMS is an unequivocal cutis laxa syndrome and expands the clinical and molecular spectrum of this group of disorders. In the neonatal period, brachydactyly and facial dysmorphism are two early distinctive signs, later followed by intellectual disability and hyperostotic skeletal dysplasia with severe dwarfism allowing differentiation of this condition from other cutis laxa phenotypes. Further studies are needed to understand the link between PTDSS1 and extra cellular matrix assembly. © 2018 The Authors.

Moyamoya disease is a rare cerebrovascular anomaly involving the intracranial carotid arteries that can present clinically with either ischemic or hemorrhagic disease. Moyamoya syndrome, indistinguishable from moyamoya disease at presentation, is associated with multiple clinical conditions including neurofibromatosis type 1, autoimmune disease, prior radiation therapy, Down syndrome, and Turner syndrome. We present the first reported case of an adult patient with previously unrecognized mosaic Turner syndrome with acute subarachnoid and intracerebral hemorrhage as the initial manifestation of moyamoya syndrome. A 52-year-old woman was admitted with a subarachnoid hemorrhage with associated flame-shaped intracerebral hemorrhage in the left frontal lobe. Physical examination revealed short stature, pectus excavatum, small fingers, micrognathia, and mild facial dysmorphism. Cerebral angiography showed features consistent with bilateral moyamoya disease, aberrant intrathoracic vessels, and an unruptured 4-mm right superior hypophyseal aneurysm. Genetic analysis confirmed a diagnosis of mosaic Turner syndrome. Our case report is the first documented presentation of adult moyamoya syndrome with subarachnoid and intracerebral hemorrhage as the initial presentation of mosaic Turner syndrome. It illustrates the utility of genetic evaluation in patients with cerebrovascular disease and dysmorphism. Copyright © 2014 National Stroke Association. Published by Elsevier Inc.

This case report aims to present a 37-year-old women striving to shape her body like a Barbie doll of which she has been fascinated since childhood. She could hardly tolerate any deviation from this beauty ideal. She has been admitted to the psychosomatic ward due to an eating disorder. The ICD-10 and DSM-5 criteria were established for axis I disorders and the German version of the SCID II interview (for DSM-4) was applied for axis II disorders. Additionally, the "modified Yale-Brown Obsessive Compulsive Scale for body dysmorphic disorder" was carried out. The diagnosis of dysmorphophobia (ICD-10: F45.21) or body dysmorphic disorder (DSM-5: 300.7) and bulimia nervosa (ICD-10: F50.2; DSM-5: 307.51) was confirmed. The patient fulfilled criteria of an avoidant, depressive and histrionic personality disorder. Psychopharmacological treatment with Fluoxetine was started and the patient participated in an intensive inpatient psychosomatic program. The body image, self-concept and the sense of shame were therapeutic key topics. The present case report focuses on body dysmorphic disorder as a distinctive entity with high prevalence. Diagnostic criteria of different classification systems were contrasted and comorbidity with eating disorders was discussed. In clinical praxis, body dysmorphic disorder remains underdiagnosed, especially when cooccurring with an eating disorder. However, the correct diagnosis could be relevant for therapy planning.

The new classification system of uterine anomalies from the European Society of Human Reproduction and Embryology and the European Society for Gynaecological Endoscopy defines T-shaped and tubular-shaped infantilis uteri as 'dysmorphic'. Such malformations have been proven to be associated with poor reproductive performance. A prospective observational study was conducted with 30 infertile women with dysmorphic uterus who underwent the novel Hysteroscopic Outpatient Metroplasty to Expand Dysmorphic Uteri (HOME-DU ) technique. Incisions are made on the uterine walls with a 5 Fr bipolar electrode. The procedure was conducted in outpatients under conscious sedation, using a 5-mm office hysteroscope. The technique was successful in all cases without complications. A net increase of uterine volume was found, as measured at hysteroscopy and three-dimensional transvaginal ultrasound (P < 0.001). Uterine morphology improved in all patients but one. At mean follow-up of 15 months, clinical pregnancy rate was 57% and term delivery rate 65%. These early data support HOME-DU as safe and effective in expanding the volume and normalizing the appearance of the uterine cavity of dysmorphic uteri. Although the cohort was small, pregnancy and live births outcomes were favourable in this poor-prognosis group, implying desirable benefits, which should be compared with other techniques.

2018-01-01

BACKGROUND: Cerebro-facio-thoracic dysplasia (CFTD) is a rare, autosomal recessive disorder characterized by facial dysmorphism, cognitive impairment and distinct skeletal anomalies and has been linked to the TMCO1 defect syndrome. OBJECTIVE: To describe two siblings with features consistent with CFTD with a novel homozygous p.Arg114* pathogenic variant in the TMCO1 gene. METHODS: We conducted a literature review and summarized the clinical features and laboratory results of two siblings with a novel pathogenic variant in the TMCO1 gene. Facial recognition analysis was utilized to assess the specificity of facial traits. CONCLUSION: The novel homozygous p.Arg114* pathogenic variant in the TMCO1 gene is responsible for the clinical features of CFTD in two siblings. Facial recognition analysis allows unambiguous distinction of this syndrome against controls. PMID:29682451

Chromosome 22q11 deletion (CATCH 22 syndrome or velocardiofacial syndrome) is one of the most frequent chromosomal syndromes. Neurological features other than cognitive disorders are probably the least-described part of the expanding phenotype of the 22q11 deletion. We report the neurological features of three unrelated children with a de novo deletion: one patient with an autistic disorder, a second patient with hypocalcaemic neonatal seizures and unusual persistent epileptic focus at electroencephalographic follow-up, and a third patient with atypical absence epilepsy. These observations enlarge the clinical and neurological spectrum of the 22q11 deletion. Awareness of such cases is necessary, and a diagnosis of the 22q11 deletion should be suspected in children with common neurological features associated with severe or mild dysmorphism. Diagnosis of the 22q11 deletion should be confirmed by fluorescence in situ hybridization analysis associated with standard chromosomal analysis.

2014-06-01

Schimke immuno-osseous dysplasia (SIOD) is a rare, severe, autosomal recessive disorder that results in spondyloepiphyseal dysplasia, renal dysfunction, immunodeficiency, facial dysmorphism and growth failure. Little is known about oral features associated with SIOD. Some of the dental anomalies encountered are specific to SIOD and have only been reported in individuals with SIOD. This paper describes the clinical and radiographic dental manifestations of SIOD in two Caucasian brothers. Both lived to be about 10 years old. After a variety of symptoms were reported, a diagnosis of SIOD was finally made when the brothers were, respectively, 5 and 8 years old. At that time, dental anomalies, such as dyschromia, bulbous crowns, short and thin roots, had not been taken into account to establish the diagnosis. However, knowledge of the dental features characteristic of this disease could have helped make the diagnosis. Although both were caries- and periodontal disease-free, special attention was focused on prevention, including dietary counselling, plaque control, oral hygiene instructions and the use of fluoridated toothpaste. The two patients were followed every 6 months, for over 2 years (until their death), by both a private dentist and a university hospital dentist, which helped them maintain good oral health. Oral hygiene was assessed at each appointment and fissure sealants were placed by the private practitioner on their first permanent molars. This report describes dental anomalies specific to SIOD that could facilitate diagnosis. Clinicians and dentists should work in collaboration to diagnose and treat children with SIOD. These patients require regular and specific dental management because of their fragile health and their characteristic dental anomalies. Ideally, preventive visits should be scheduled every 6 months in addition to curative visits as needed.

Visual processing in anorexia nervosa and body dysmorphic disorder: similarities, differences, and future research directions

Madsen, Sarah K.; Bohon, Cara; Feusner, Jamie D.

2013-01-01

Anorexia nervosa (AN) and body dysmorphic disorder (BDD) are psychiatric disorders that involve distortion of the experience of one’s physical appearance. In AN, individuals believe that they are overweight, perceive their body as “fat,” and are preoccupied with maintaining a low body weight. In BDD, individuals are preoccupied with misperceived defects in physical appearance, most often of the face. Distorted visual perception may contribute to these cardinal symptoms, and may be a common underlying phenotype. This review surveys the current literature on visual processing in AN and BDD, addressing lower- to higher-order stages of visual information processing and perception. We focus on peer-reviewed studies of AN and BDD that address ophthalmologic abnormalities, basic neural processing of visual input, integration of visual input with other systems, neuropsychological tests of visual processing, and representations of whole percepts (such as images of faces, bodies, and other objects). The literature suggests a pattern in both groups of over-attention to detail, reduced processing of global features, and a tendency to focus on symptom-specific details in their own images (body parts in AN, facial features in BDD), with cognitive strategy at least partially mediating the abnormalities. Visuospatial abnormalities were also evident when viewing images of others and for non-appearance related stimuli. Unfortunately no study has directly compared AN and BDD, and most studies were not designed to disentangle disease-related emotional responses from lower-order visual processing. We make recommendations for future studies to improve the understanding of visual processing abnormalities in AN and BDD. PMID:23810196

Consistent with well-documented structural and microstructural abnormalities in prenatal alcohol exposure (PAE), recent studies suggest that functional connectivity (FC) may also be disrupted. We evaluated whole-brain FC in a large multi-site sample, examined its cognitive correlates, and explored its potential to objectively identify neurodevelopmental abnormality in individuals without definitive dysmorphic features. Included were 75 children with PAE and 68 controls from four sites. All participants had documented heavy prenatal alcohol exposure. All underwent a formal evaluation of physical anomalies and dysmorphic facial features. MRI data were collected using modified matched protocols on three platforms (Siemens, GE, and Philips). Resting-state FC was examined using whole-brain graph theory metrics to characterize each individual's connectivity. Although whole-brain FC metrics did not discriminate prenatally-exposed from unexposed overall, atypical FC (> 1 standard deviation from the grand mean) was significantly more common (2.7 times) in the PAE group vs. In a subset of 55 individuals (PAE and controls) whose dysmorphology examination could not definitively characterize them as either Fetal Alcohol Syndrome (FAS) or non-FAS, atypical FC was seen in 27 % of the PAE group, but 0 % of controls. Across participants, a 1 % difference in local network efficiency was associated with a 36 point difference in global cognitive functioning. Whole-brain FC metrics have potential to identify individuals with objective neurodevelopmental abnormalities from prenatal alcohol exposure. When applied to individuals unable to be classified as FAS or non-FAS from dysmorphology alone, these measures separate prenatally-exposed from non-exposed with high specificity.

Body dysmorphic disorder (BDD), a distressing or impairing preoccupation with an imagined or slight defect in appearance, has been described for more than a century and increasingly studied over the past several decades. This paper provides a focused review of issues pertaining to BDD that are relevant to DSM-V. The review presents a number of options and preliminary recommendations to be considered for DSM-V: 1) Criterion A may benefit from some rewording, without changing its focus or meaning; 2) Potential disadvantages of adding a new criterion to reflect BDD compulsive behaviors seem to outweigh potential advantages, but adding such a criterion remains an option that can be considered; 3) A clinical significance criterion seems necessary for BDD to differentiate it from normal appearance concerns; 4) BDD and eating disorders have some overlapping features and need to be differentiated; some minor changes to DSM-IV’s criterion C are suggested; 5) BDD should not be broadened to include body integrity identity disorder (apotemnophilia) or olfactory reference syndrome; 6) There is no compelling evidence for including diagnostic features or subtypes that are specific to gender-related, age-related, or cultural manifestations of BDD; 7) Adding muscle dysmorphia as a specifier may have clinical utility; and 8) The ICD-10 criteria for hypochondriacal disorder are not suitable for BDD, and there is no empirical evidence that BDD and hypochondriasis are the same disorder. The issue of how BDD’s delusional variant should be classified in DSM-V is briefly discussed and will be addressed more extensively in a separate paper. PMID:20533368

Kuechler et al. [2011] reported five patients with interstitial deletions in 8q22.2-q22.3 who had intellectual disability, epilepsy, and dysmorphic features. We report on a new patient with the smallest overlapping de novo deletion in 8q22.3 and refined the phenotype. The proposita was an 8-year-old girl, who developed seizures at 10 months, and her epileptic seizure became severe and difficult to control with antiepileptic drugs. She also exhibited developmental delay and walked alone at 24 months. She was referred to us for evaluation for developmental delay and epilepsy at the age of 8 years. She had intellectual disability (IQ 37 at 7 years) and autistic behavior, and spoke two word sentences at 8 years. She had mild dysmorphic features, including telecanthus and thick vermilion of the lips. Array comparative genomic hybridization detected a 1.36 Mb deletion in 8q22.3 that encompassed RRM2B and NCALD, which encode the small subunit of p53-inducible ribonucleotide reductase and neurocalcin delta in the neuronal calcium sensor family of calcium-binding proteins, respectively. The minimum overlapping region between the present and previously reported patients is considered to be a critical region for the phenotype of the deletion in 8q22.3. We suggest that the deletion in 8q22.3 may represent a clinically recognizable condition, which is characterized by intellectual disability and epilepsy. © 2014 Wiley Periodicals, Inc.

RASopathies are a class of developmental syndromes that result from congenital mutations in key elements of the RAS/RAF/MEK signaling pathway. A well-recognized RASopathy is the cardio-facio-cutaneous (CFC) syndrome characterized by a distinctive facial appearance, heart defects, and mental retardation. Clinically diagnosed CFC patients carry germ-line mutations in four different genes, B-RAF, MEK1, MEK2, and K-RAS. B-RAF is by far the most commonly mutated locus, displaying mutations that most often result in constitutive activation of the B-RAF kinase. Here, we describe a mouse model for CFC generated by germ-line expression of a B-RafLSLV600E allele. This targeted allele allows low levels of expression of B-RafV600E, a constitutively active B-Raf kinase first identified in human melanoma. B-Raf+/LSLV600E mice are viable and display several of the characteristic features observed in CFC patients, including reduced life span, small size, facial dysmorphism, cardiomegaly, and epileptic seizures. These mice also show up-regulation of specific catecholamines and cataracts, two features detected in a low percentage of CFC patients. In addition, B-Raf+/LSLV600E mice develop neuroendocrine tumors, a pathology not observed in CFC patients. These mice may provide a means of better understanding the pathophysiology of at least some of the clinical features present in CFC patients. Moreover, they may serve as a tool to evaluate the potential therapeutic efficacy of B-RAF inhibitors and establish the precise window at which they could be effective against this congenital syndrome.

Psychiatric disorders are known to influence the result of many surgical procedures. Body dysmorphic disorder (BDD) is found in many patients undergoing plastic surgery. The prevalence before functional rhinosurgery has not been examined so far. The aim of this study was to determine the prevalence of depression and BDD before functional rhinosurgery. 201 patients were prospectively examined with a questionnaire before functional rhinosurgery. Beck-Depression-Index was used to rate depression, the PISA body dsymorphic symptom scale was used to evaluate the likelihood that a patient suffers from body dysmoprhic disorder. 186 patients returned a complete questionnaire. In 33.9% showed a mild or strong indication for a body dysmorphic disorder. Patients who were planned to undergo septorhinoplasty had a significantly higher scores in the PISA-scale compared to patients before septoplasty. 1.7% patients were depressive without a significant difference between the planned surgical procedure. Many patients before functional septorhinoplasty show signs of body dysmorphic disorder. Whether this influences the subjective clinical outcome needs to be evaluated in further studies. © Georg Thieme Verlag KG Stuttgart · New York.

Here, we describe a female patient with autism spectrum disorder and dysmorphic features that harbors a complex genetic alteration, involving a de novo balanced translocation t(2;X)(q11;q24), a 5q11 segmental trisomy and a maternally inherited isodisomy on chromosome 5. All the possibly damaging genetic effects of such alterations are discussed. In light of recent findings on ASD genetic causes, the hypothesis that all these alterations might be acting in orchestration and contributing to the phenotype is also considered.

The major clinical manifestations of DiGeorge syndrome (DGS; MIM 188400), which reflect developmental abnormalities of the 3d and 4th pharyngeal pouch derivatives, include thymus- and parathyroid-gland aplasia or hypoplasia and conotruncal cardiac malformations. The additional dysmorphic facial features, such as hypertelorism, cleft lip and palate, bifid uvula, and small/low-set ears, which are also common, presumably reflect the same defect. The DGS phenotype has been associated with chromosome abnormalities and, sometimes, is the effect of teratogenic agents such as retinoic acid and alcohol. 53 refs., 1 fig.

Focal giant cell cardiomyopathy with Beckwith-Wiedemann syndrome.

Cardiac involvement in Beckwith-Wiedemann syndrome is mostly limited to mild cardiomegaly. Although these patients have visceromegaly, macroglossia, gigantism, and adrenal cytomegaly, no significant myocardial changes have been described. An infant with dysmorphic features of this syndrome had supraventricular tachycardia since birth. Nodular lesions were present in the right atrium. Morphologically these lesions were composed of hypertrophic myocardial fibers admixed with multinucleated giant cells of myogenic origin. The exact nature of these lesions remains undetermined. It is postulated that hypertrophic myocardial cells may represent cardiac cytomegaly as a manifestation of the accelerated growth potential of cells seen with this syndrome.

Prader-Willi syndrome (PWS) is the most frequent cause of secondary obesity, characterized by neonatal hypotonia, dysmorphic facies, acromicria, hypogonadism, stunted growth, obesity, behavioural disturbances and cognitive impairment. Clinical diagnosis is confirmed by alteration of imprinted genes on the proximal long arm of chromosome 15 (15q11-13) for deletion, translocation, uniparental disomy for maternal chromosome 15 or imprinting center defect. Methylation test is the most reliable test for diagnosis. This issue explains diagnostic tests, clinical, metabolic, endocrinological features, and the most frequent complications observed in this syndrome. Precocious diagnosis and multidisciplinary approach allow in these patients to prevent the severe obesity and linked complications.

KIAA2022 is an X-linked intellectual disability (XLID) syndrome affecting males more severely than females. Few males with KIAA2022 variants and XLID have been reported. We present a clinical report of two unrelated males, with two nonsense KIAA2022 pathogenic variants, with profound intellectual disabilities, limited language development, strikingly similar autistic behavior, delay in motor milestones, and postnatal growth restriction. Patient 1, 19-years-old, has long ears, deeply set eyes with keratoconus, strabismus, a narrow forehead, anteverted nares, café-au-lait spots, macroglossia, thick vermilion of the upper and lower lips, and prognathism. He has gastroesophageal reflux, constipation with delayed rectosigmoid colonic transit time, difficulty regulating temperature, several musculoskeletal issues, and a history of one grand mal seizure. Patient 2, 10-years-old, has mild dysmorphic features, therapy resistant vomiting with diminished motility of the stomach, mild constipation, cortical visual impairment with intermittent strabismus, axial hypotonia, difficulty regulating temperature, and cutaneous mastocytosis. Genetic testing identified KIAA2022 variant c.652C > T(p.Arg218*) in Patient 1, and a novel nonsense de novo variant c.2707G > T(p.Glu903*) in Patient 2. We also summarized features of all reported males with KIAA2022 variants to date. This report not only adds knowledge of a novel pathogenic variant to the KIAA2022 variant database, but also likely extends the spectrum by describing novel dysmorphic features and medical conditions including macroglossia, café-au-lait spots, keratoconus, severe cutaneous mastocytosis, and motility problems of the GI tract, which may help physicians involved in the care of patients with this syndrome. Lastly, we describe the power of social media in bringing families with rare medical conditions together. © 2018 Wiley Periodicals, Inc.

Patients suffering from body dysmorphic disorder (BDD) are preoccupied with an imagined or minor defect in appearance that causes significant distress and impairment in social and occupational functioning. Despite a rate of up to 15% of BDD patients reported in cosmetic surgery settings, there is no consensus on the best management for these patients. The main purpose of this article was to conduct a literature review on BDD and cosmetic surgery. Properly trained healthcare professionals in recognizing and diagnosing this pathology is essential for the delivery of quality psychiatric care while taking into account the high prevalence of body dysmorphic disorder patients in cosmetic surgery and the poor outcome of these patients following cosmetic procedures.

Is Body Dysmorphic Disorder Associated with Abnormal Bodily Self-Awareness? A Study Using the Rubber Hand Illusion

PubMed Central

Kaplan, Ryan A.; Enticott, Peter G.; Hohwy, Jakob; Castle, David J.; Rossell, Susan L.

2014-01-01

Evidence from past research suggests that behaviours and characteristics related to body dissatisfaction may be associated with greater instability of perceptual body image, possibly due to problems in the integration of body-related multisensory information. We investigated whether people with body dysmorphic disorder (BDD), a condition characterised by body image disturbances, demonstrated enhanced susceptibility to the rubber hand illusion (RHI), which arises as a result of multisensory integration processes when a rubber hand and the participant's hidden real hand are stimulated in synchrony. Overall, differences in RHI experience between the BDD group and healthy and schizophrenia control groups (n = 17 in each) were not significant. RHI strength, however, was positively associated with body dissatisfaction and related tendencies. For the healthy control group, proprioceptive drift towards the rubber hand was observed following synchronous but not asynchronous stimulation, a typical pattern when inducing the RHI. Similar drifts in proprioceptive awareness occurred for the BDD group irrespective of whether stimulation was synchronous or not. These results are discussed in terms of possible abnormalities in visual processing and multisensory integration among people with BDD. PMID:24925079

Characteristics of 22q 11.2 deletion syndrome undiagnosed until adulthood: an example suggesting the importance of psychiatric manifestations

Patients with chromosome 22q11.2 deletion syndrome (22q11.2DS) exhibit various combinations of signs and symptoms including facial dysmorphism, thymus absence, hypoparathyroidism, cellular immunodeficiency and cardiac abnormalities caused by microdeletion of chromosome 22q11.2. Most cases are diagnosed during post-natal cardiac evaluation, though some are diagnosed at later stages. We report the case of a 39-year-old man with 22q11.2DS presenting with seizure due to tardily manifested hypocalcaemia and anxiety disorder. Our experience suggests that 22q11.2DS patients lacking fatal or well-recognised manifestations such as cardiac defects, immunodeficiency and facial dysmorphism tend to survive without medical attention, and are therefore overlooked. Recognition of the age-related variance of the manifestations, and specifically of tardily manifested hypocalcaemia and psychiatric or developmental disorders as manifestations of 22q11.2DS in adulthood, is important for diagnosis and can also help us provide appropriate medical and psychosocial support for newly diagnosed 22q11.2DS patients in adolescence or adulthood and their families.

Set shifting and visuospatial organization deficits in body dysmorphic disorder.

Individuals with body dysmorphic disorder (BDD) over-attend to perceived defect(s) in their physical appearance, often becoming "stuck" obsessing about perceived flaws and engaging in rituals to hide flaws. These symptoms suggest that individuals with BDD may experience deficits in underlying neurocognitive functions, such as set-shifting and visuospatial organization. These deficits have been implicated as risk and maintenance factors in disorders with similarities to BDD but have been minimally investigated in BDD. The present study examined differences in neurocognitive functions among BDD participants (n = 20) compared to healthy controls (HCs; n = 20). Participants completed neuropsychological assessments measuring set-shifting (Cambridge Neuropsychological Test Automated Battery Intra-Extra Dimensional Set Shift [IED] task) and visuospatial organization and memory (Rey-Osterrieth Complex Figure Test [ROCF]). Results revealed a set-shifting deficit among BDD participants compared to HCs on the IED. On the ROCF, BDD participants exhibited deficits in visuospatial organization compared to HCs, but they did not differ in visuospatial memory compared to HCs. Results did not change when accounting for depression severity. Findings highlight neurocognitive deficits as potential endophenotype markers of clinical features (i.e., delusionality). Understanding neuropsychological deficits may clarify similarities and differences between BDD and related disorders and may guide targets for BDD treatment. Copyright © 2017 Elsevier B.V.

Ross, M.; Pinsky, L.; Teebi, A.

Chromosomal abnormalities involving chromosome 7q are rare; we report a case of partial duplication 7q. The propositus was born at 34 weeks by cesarian section, decided because of oligohydramnios, severe intrauterine growth retardation and fetal immobility. At birth, the baby was under the 5th percentile for height, weight and head circumference and had dysmorphic features, including slight asymmetry of the face, bilateral epicanthus, hypoplastic nasal bridge, short globular nose, asymmetrical dysplastic ears, fifth finger clinodactyly, short second and fifth toe. Ultrasound examination showed atrial and ventricular septal defects. At 18 months, the child had a fracture of the femur, secondarymore » to a minor trauma; skeletal X-rays showed generalized osteoporosis and normal healing. The karyotype with GTG-banding showed a de novo partial duplication of the long arm of chromosome 7 (46,XX,dup(7)(q11.23{r_arrow}q21.2)). Fluorescence in situ hybridization with a painting probe specific for chromosome 7 confirmed the intra-chromosomal rearrangement. The patient`s phenotype and his chromosomal abnormality do not match the previously reported cases of partial trisomy 7q. This case confirms the importance of FISH for the delineation of the chromosomal inbalance in structural chromosomal aberrations.« less

A de novo Mutation in KMT2A (MLL) in monozygotic twins with Wiedemann-Steiner syndrome.

Growth deficiency, psychomotor delay, and facial dysmorphism was originally described in a male patient in 1989 by Wiedemann et al. and later in 2000 by Steiner et al. Wiedemann-Steiner syndrome (WSS) has since been described only a few times in the literature, with the phenotypic spectrum both expanding and becoming more delineated with each patient reported. We report on the clinical and molecular features of monozygotic twins with a de novo mutation in KMT2A. Single nucleotide polymorphism (SNP) microarray was done on both twins and whole-exome sequencing was done using both parents and one of the affected twins. SNP microarray confirmed that they were monozygotic twins. A de novo heterozygous variant (p. Arg1083*) in the KMT2A gene was identified through whole-exome sequencing, confirming the diagnosis of WSS. In this study, we have identified a de novo mutation in KMT2A associated with psychomotor developmental delay, facial dysmorphism, short stature, hypertrichosis cubiti, and small kidneys. This finding in monozygotic twins gives specificity to the WSS. The description of more cases of WSS is needed for further delineation of this condition. Small kidneys with normal function have not been described in this condition in the medical literature before. © 2015 Wiley Periodicals, Inc.

Nance-Horan Syndrome (NHS) (OMIM: 302350) is a rare X-linked developmental disorder characterized by bilateral congenital cataracts, with occasional dental anomalies, characteristic dysmorphic features, brachymetacarpia and mental retardation. Carrier females exhibit similar manifestations that are less severe than in affected males. Here, we report a four-generation Chinese family with multiple affected individuals presenting Nance-Horan Syndrome. Whole-exome sequencing combined with RT-PCR and Sanger sequencing was used to search for a genetic cause underlying the disease phenotype. Whole-exome sequencing identified in all affected individuals of the family a novel donor splicing site mutation (NM_198270: c.1045 + 2T > A) in intron 4 of the gene NHS, which maps to chromosome Xp22.13. The identified mutation results in an RNA processing defect causing a 416-nucleotide addition to exon 4 of the mRNA transcript, likely producing a truncated NHS protein. The donor splicing site mutation NM_198270: c.1045 + 2T > A of the NHS gene is the causative mutation in this Nance-Horan Syndrome family. This research broadens the spectrum of NHS gene mutations, contributing to our understanding of the molecular genetics of NHS.

17p13.1 Deletion encompassing TP53 has been described as a syndrome characterized by intellectual disability and dysmorphic features. Only one case with a 17p13.1 duplication encompassing TP53 has been reported in a patient with intellectual disability, seizures, obesity, and diabetes mellitus. Here, we present a patient with a 17p13.1 duplication who exhibited obesity and intellectual disability, similar to the previous report. The 9-year-old proposita was referred for the evaluation of intellectual disability and obesity. She also exhibited insulin resistance and liver dysfunction. She had wide palpebral fissures, upturned nostrils, a long mandible, short and slender fingers, and skin hyperpigmentation. Array comparative genomic hybridization (array CGH) detected a 3.2 Mb duplication of 17p13.1-p13.2 encompassing TP53, FXR2, NLGN2, and SLC2A4, which encodes the insulin-responsive glucose transporter 4 (GLUT4) associated with insulin-stimulated glucose uptake in adipocytes and muscle. We suggest that 17p13.1 duplication may represent a clinically recognizable condition characterized partially by a characteristic facial phenotype, developmental delay, and obesity. © 2014 Wiley Periodicals, Inc.

Relative relationships of general shame and body shame with body dysmorphic phenomenology and psychosocial outcomes.

PubMed

Weingarden, Hilary; Renshaw, Keith D; Davidson, Eliza; Wilhelm, Sabine

2017-07-01

Body Dysmorphic Disorder (BDD) is characterized by a preoccupation with a perceived flaw in appearance and repetitive avoidance behaviors. BDD involves severe psychosocial outcomes (e.g., depression, suicidality, functional impairment). Identifying correlates of BDD symptoms and outcomes can inform treatment. Shame, a painful emotion felt in response to critical self-judgment, may be one key correlate. However, research on shame in BDD is scarce and previous studies have not distinguished general shame from body shame. This study examines the relative relationships between body shame and general shame with body dysmorphic phenomenology and psychosocial outcomes. Participants ( N = 184) were recruited online via BDD organizations and completed a survey. Path analysis was used to examine associations between body and general shame with 1) body dysmorphic phenomenology and 2) depression severity, suicide risk, and functional impairment. Both types of shame were differentially related to outcomes. Body shame was more strongly related to phenomenology, whereas general shame was more strongly related to psychosocial outcomes. Thus, it may be important for BDD treatment to focus on reducing both general and body shame. Further research should evaluate whether current treatments adequately address and reduce general and body shame, and whether addressing shame promotes better treatment outcomes.

Introduction: The present study examined the favorable attitude of a sample of female university students regarding elective cosmetic surgery, body dysmorphic disorder, self-esteem and body dissatisfaction following a media literacy training intervention. Methods: This study was a quasi-experimental type. The study sample included 140 female university students who were allocated to either the intervention (n=70) or the control group (n=70). Attitude toward cosmetic surgery, body dysmorphic disorder, self-esteem and, body satisfaction was measured in both groups before the intervention and 4 weeks later. Four media literacy training sessions were conducted over 4 weeks for the intervention group. The data was analyzed through analysis of covariance, student’s paired-samples t test, and Pearson correlation. Results: Our findings showed that favorable attitude, body dysmorphic disorder and body dissatisfaction scores were significantly lower (p<0.05) in the intervention group than the control group. Furthermore, self-esteem score increased significantly in the intervention group. Conclusions: Our results underscores the importance of media literacy intervention in decreasing female’s favorable attitude towards elective cosmetic surgery, body dysmorphic disorder and body dissatisfaction as well as increasing self-esteem.

Lozzio, C.B.; Bamberger, E.; Anderson, I.

1994-09-01

A partial trisomy 13 was detected prenatally in an amniocentesis performed due to the following ultrasound abnormalities: open sacral neural tube defect (NTD), a flattened cerebellum, and lumbar/thoracic hemivertebrae. Elevated AFP and positive acetylcholinesterase in amniotic fluid confirmed the open NTD. Chromosome analysis showed an extra acrocentric chromosome marker. FISH analysis with the painting probe 13 showed that most of the marker was derived from this chromosome. Chromosomes on the parents revealed that the mother had a balanced reciprocal translocation t(2;13)(q23;q21). Dual labeling with painting chromosomes 2 and 13 on cells from the mother and from the amniotic fluid identifiedmore » the marker as a der(13)t(2;13)(p23;q21). Thus, the fetus had a partial trisomy 13 and a small partial trisomy 2p. The maternal grandfather was found to be a carrier for this translocation. Fetal demise occurred a 29 weeks of gestation. The fetus had open lumbar NTD and showed dysmorphic features, overlapping fingers and imperforate anus. This woman had a subsequent pregnancy and chorionic villi sample showed that this fetus was normal. Another case with an abnormal chromosome 13 was a newborn with partial monosomy 13 due to the presence of a ring chromosome 13. This infant had severe intrauterine growth retardation, oligohydramnios, dysmorphic features and multiple congenital microphthalmia, congenital heart disease, absent thumbs and toes and cervical vertebral anomalies. Chromosome studies in blood and skin fibroblast cultures showed that one chromosome 3 was replaced by a ring chromosome of various sizes. This ring was confirmed to be derived from chromosome 13 using the centromeric 21/13 probe.« less

Fanconi Anemia (FA) is a rare and heterogeneous genetic syndrome. It is associated with short stature, bone marrow failure, high predisposition to cancer, microcephaly and congenital malformation. Many genes have been associated with FA. Previously, two adult patients with biallelic pathogenic variant in Breast Cancer 1 gene (BRCA1) had been identified in Fanconi Anemia-like condition. The proband was a 2.5 year-old girl with severe short stature, microcephaly, neurodevelopmental delay, congenital heart disease and dysmorphic features. Her parents were third degree cousins. Routine screening tests for short stature was normal. We conducted whole exome sequencing (WES) of the proband and used an analysis pipeline to identify rare nonsynonymous genetic variants that cause short stature. We identified a homozygous loss-of-function BRCA1 mutation (c.2709T > A; p. Cys903*), which promotes the loss of critical domains of the protein. Cytogenetic study with DEB showed an increased chromosomal breakage. We screened heterozygous parents of the index case for cancer and we detected, in her mother, a metastatic adenocarcinoma in an axillar lymph node with probable primary site in the breast. It is possible to consolidate the FA-like phenotype associated with biallelic loss-of-function BRCA1, characterized by microcephaly, short stature, developmental delay, dysmorphic face features and cancer predisposition. In our case, the WES allowed to establish the genetic cause of short stature in the context of a chromosome instability syndrome. An identification of BRCA1 mutations in our patient allowed precise genetic counseling and also triggered cancer screening for the patient and her family members.

The aim of our study was to determine the etiologic distribution of 46,XX disorder of sexual development (DSD) according to the new DSD classification system and to evaluate the clinical features of this DSD subgroup in our patient cohort. The evaluation criteria and clinical findings of 95 46,XX patients were described by clinical presentation, gonadal morphology, genital anatomy, associated dysmorphic features, presence during prenatal period with/without postnatal virilization, hormonal characteristics, and presence or absence of steroidogenic defects among 319 patients with DSD. Types and ratios of each presentation of our 95 patients with 46,XX DSD were as follows: 82 had androgen excess (86.3%): (74 had classical congenital adrenal hyperplasia, 2 had CAH variant possibility of P450-oxidoreductase gene defect), 6 had disorders of ovarian development (6.3%): (1 patient had gonadal dysgenesis with virilization at birth with bilateral streak gonad, 4 patients had complete gonadal dysgenesis, and 1 patient had ovotesticular DSD) and 7 had other 46,XX DSD. Two sisters, who had 46,XX complete gonadal dysgenesis,were diagnosed with Perrault Syndrome with ovarian failure due to streak gonads and associated with sensorineural deafness. 46,XX DSD are usually derived from intrauterine virilization and CAH is the most common cause of 46,XX DSD due to fetal androgen exposure.

2017-01-01

Chromosome 22q11.2 deletion syndrome (22q11.2 DS) has a very wide phenotypic spectrum that includes dysmorphic features, cardiac anomalies, and hypocalcemia arising from hypoparathyroidism. We herein describe an adult case of 22q11.2 DS with associated hypoparathyroidism and anomalies of the aortic arch. Because the patient had been diagnosed with primary hypoparathyroidism at another hospital, a diagnosis of 22q11.2 DS had been overlooked. A chest X-ray examination revealed widening of the mediastinum caused by a high-positioned right aortic arch, and we subsequently confirmed a diagnosis of 22q11.2 DS using fluorescence in situ hybridization. Because primary hypoparathyroidism is a rare disorder, physicians should be aware of the variable phenotypic features of 22q11.2 DS. PMID:28381757

We describe a family with four members, a mother, two sons, and a daughter, who show clinical features consistent with X linked Alport syndrome. The two males presented with additional features including mental retardation, dysmorphic facies with marked midface hypoplasia, and elliptocytosis. The elliptocytosis was not associated with any detectable abnormalities in red cell membrane proteins; red cell membrane stability and rigidity was normal on ektacytometry. Molecular characterisation suggests a submicroscopic X chromosome deletion encompassing the entire COL4A5 gene. We propose that the additional abnormalities found in the affected males of this family are attributable to deletion or disruption of X linked recessive genes adjacent to the COL4A5 gene and that this constellation of findings may represent a new X linked contiguous gene deletion syndrome.

Myhre syndrome is a rare, distinctive syndrome due to specific gain-of-function mutations in SMAD4. The characteristic phenotype includes short stature, dysmorphic facial features, hearing loss, laryngotracheal anomalies, arthropathy, radiographic defects, intellectual disability, and a more recently appreciated spectrum of cardiovascular defects with a striking fibroproliferative response to surgical intervention. We report four newly described patients with typical features of Myhre syndrome who had (i) a mildly narrow descending aorta and restrictive cardiomyopathy; (ii) recurrent pericardial and pleural effusions; (iii) a large persistent ductus arteriosus with juxtaductal aortic coarctation; and (iv) restrictive pericardial disease requiring pericardiectomy. Additional information is provided about a fifth previously reported patient with fatal pericardial disease. A literature review of the cardiovascular features of Myhre syndrome was performed on 54 total patients, all with a SMAD4 mutation. Seventy percent had a cardiovascular abnormality including congenital heart defects (63%), pericardial disease (17%), restrictive cardiomyopathy (9%), and systemic hypertension (15%). Pericarditis and restrictive cardiomyopathy are associated with high mortality (three patients each among 10 deaths); one patient with restrictive cardiomyopathy also had epicarditis. Cardiomyopathy and pericardial abnormalities distinguish Myhre syndrome from other disorders caused by mutations in the TGF-β signaling cascade (Marfan, Loeys-Dietz, or Shprintzen-Goldberg syndromes). We hypothesize that the expanded spectrum of cardiovascular abnormalities relates to the ability of the SMAD4 protein to integrate diverse signaling pathways, including canonical TGF-β, BMP, and Activin signaling. The co-occurrence of congenital and acquired phenotypes demonstrates that the gene product of SMAD4 is required for both developmental and postnatal cardiovascular homeostasis. © 2016 Wiley Periodicals, Inc. © 2016 Wiley Periodicals, Inc.

Abstract Rationale: Tricho-hepato-enteric syndrome (THES) is a rare disorder caused by mutations in the TTC37 or SKIV2L genes and characterized by chronic diarrhea, liver disease, hair abnormalities, and high mortality in early childhood due to severe infection or liver cirrhosis. Patient concerns: The patient is the second child of three siblings born to non-consanguineous healthy Japanese parents. She had intrauterine growth retardation and was delivered at 33 weeks of gestation due to placental abruption. She presented with watery diarrhea, elevated levels of liver enzymes, multiple episodes of recurrent bacterial infection, and mild mental retardation. She had facial dysmorphism, including prominent forehead and hypertelorism, and had woolly hair without trichorrhexis nodosa. Diagnosis: Clinical features led to consideration of THES. Novel compound heterozygous nonsense mutations, c.1420G>T (p.Q474∗) and c.3262G>T (p.E1088∗), in the SKIV2L gene were identified in the patient, and decreased levels of SKIV2L protein expression were revealed by flow cytometry and confirmed by western blot analysis using patient peripheral blood mononuclear cells (PBMCs). Interventions: Total parenteral nutrition was required from day 30 to day 100. Trimethoprim-sulfamethoxazole prophylaxis was started at the age of 7 years after multiple episodes of bacterial pneumonia and otitis media. Outcomes: Chronic diarrhea persisted for more than 10 years, but the symptoms gradually improved with age. At the age of 13 years, she started a normal diet in combination with oral nutritional supplementation and her height and weight were just below the 3rd percentile for healthy individuals. She developed secondary sex characteristics, and menarche occurred at the age of 12 years. Facial dysmorphism, including prominent forehead and hypertelorism, and woolly hair without trichorrhexis nodosa became noticeable as she matured. Lessons: Physicians must be aware of THES when they encounter a patient with infantile diarrhea, hair abnormalities, immune deficiency, mental retardation, and liver disease. Moreover, flow cytometric detection of SKIV2L protein in PBMCs may facilitate early diagnosis. PMID:29145277

Prevalence of and associations between body dysmorphic concerns, obsessive beliefs and social anxiety.

Physical attractiveness has been of concern in different cultures and at different times. Physical attractiveness can influence one's thoughts and actions, and concerns regarding body image can be destructive, giving rise to psychological problems. The purpose of the present study was to determine the prevalence of body dysmorphic concerns, related sex differences and comorbidity with social anxiety and obsessive beliefs. Using a stratified and cluster sampling procedure, 1,200 males and females were randomly selected. Self-report measures on body image, social anxiety and obsessive beliefs were distributed of which 843 completed questionnaires (54.9% males and 45.1% females) were returned (return rate of 70.25%). Therefore, data pertaining to 463 males and 380 females ranging in age from 17 to 20 years with a mean age of 18.12 years (SD = 1.06) were analyzed. Findings suggest a prevalence rate of 19.1% for body dysmorphic disorder, 23.6% for social anxiety and 8.8% for obsessive beliefs. Both social anxiety and obsessive beliefs were found to be comorbid with body dysmorphic concerns. The percentage of individuals reporting comorbid social anxiety (12.9%) was greater than that of those reporting comorbid obsessive beliefs (6.4%). Males with body dysmorphic concerns reported more obsessive beliefs (8.2% versus 4.1%), while their female counterparts reported more social anxiety (23.4% versus 4.2%). In males, body image concerns appear to be more cognitive in quality, while in females, body image concerns seem more emotional in tone. As the measures used do not yield formal diagnoses, findings should be viewed with caution. Copyright © 2013 Wiley Publishing Asia Pty Ltd.

The drive for muscle leanness: a complex case with features of muscle dysmorphia and eating disorder not otherwise specified.

PubMed

Cafri, G; Blevins, N; Thompson, J K

2006-12-01

Muscle dysmorphia has been described as a subtype of body dysmorphic disorder in which an individual experiences severe body image disturbance related to muscularity. The current case is of a 20-year-old man who describes a history of muscle dysmorphia in which the nature of the body image concern is related to leanness (i.e., muscularity in the absence of body fat), as opposed to increasing muscle mass, which is how muscle dysmorphia has typically been characterized in the literature. The case illustrates the need to consider this additional facet of body image when diagnosing muscle dysmorphia.

Robinow syndrome comprises dysmorphic facial features, short stature, brachymesomelia, segmental spine defects, and genital hypoplasia. The range of severity in this disorder is broad. We report on the clinical and molecular findings of two sib pairs from the same extended family with Robinow syndrome due to a novel intragenic ROR2 deletion involving exons 6 and 7 that could not be detected by sequencing. The affected individuals exhibited variability with respect to the cleft lip, cleft palate, and cardiac findings and for the presence in one of the patients of syringomyelia, which has not been previously reported in Robinow syndrome.

Laron syndrome is a rare cause of short stature due to an abnormality of growth hormone receptor (GHR). It is characterized by poor phenotype-genotype correlation and geographic predilection essentially in the Mediterranean rim, the Middle East and Indian subcontinent. This syndrome corresponds to an endogenous and exogenous complete insensitivity of GH and manifests by early hypoglycemia, an extremely severe short stature and dysmorphic features contrasting with high levels of circulating GH. To date, treatment with recombinant IGF1 is the only treatment option that has improved the terrible prognosis in these patients but does not actually realize the conditions for genuine replacement therapy.

A 4 year 3 month old boy with insulin dependent diabetes mellitus (IDDM), autoimmune thyroiditis, slight mental retardation, facial dysmorphism, and a de novo ring chromosome 18 (deletion 18q22.3-18qter) is described. This unique association of defects could represent a chance association. Alternatively, the clinical features could be the result of the chromosomal aberration. If so, one could speculate that a gene or genes on chromosome 18 might act as a suppressor or activator of the autoimmune process by itself or in concert with other IDDM loci.

2006-01-01

Limited research exists on muscle dysmorphia (MD) in men and in nonclinical populations. The current study evaluated types of body image disturbance among 237 male weightlifters. Latent class analysis of 8 measures of body image disturbance revealed 5 independent types of respondents: Dysmorphic, Muscle Concerned, Fat Concerned, Normal Behavioral, and Normal. One-way analysis of variance of independent measures of body image disturbance and associated psychopathology confirmed significant differences between groups. The Dysmorphic group reported a pattern of body image disturbance consistent with MD by displaying a high overall level of body image disturbance, symptoms of associated psychopathology, steroid use, and appearance-controlling behavior. Findings generally supported classifying MD as a subtype of body dysmorphic disorder and an obsessive-compulsive spectrum disorder. Implications for studying body image disturbance in male weightlifters, and further evaluation of the MD diagnostic criteria are discussed.

Global developmental delay (GDD) and intellectual disability (ID) are frequent reasons for consultation in paediatric neurology departments. Nowadays, array comparative genomic hybridisation (array-CGH) is one of the most widely used techniques for diagnosing these disorders. Our purpose was to determine the phenotypic features associated with pathological results in this genetic test. We conducted a blind study of the epidemiological, clinical, anthropometric, and morphological features of 80 patients with unexplained ID to determine which features were associated with pathological results in array-CGH. Pathological results were found in 27.5% of the patients. Factors associated with pathological results in array-CGH were a family history of GDD/ID (OR = 12.1), congenital malformations (OR = 5.33), having more than 3 facial dysmorphic features (OR = 20.9), and hypotonia (OR = 3.25). Our findings are consistent with those reported by other published series. We therefore conclude that the probability of having pathological results in array-CGH increases with the presence of any of the features mentioned above in patients with ID/GDD.

Genomic rearrangements involving AUTS2 (7q11.22) are associated with autism and intellectual disability (ID), although evidence for causality is limited. By combining the results of diagnostic testing of 49,684 individuals, we identified 24 microdeletions that affect at least one exon of AUTS2, as well as one translocation and one inversion each with a breakpoint within the AUTS2 locus. Comparison of 17 well-characterized individuals enabled identification of a variable syndromic phenotype including ID, autism, short stature, microcephaly, cerebral palsy, and facial dysmorphisms. The dysmorphic features were more pronounced in persons with 3′ AUTS2 deletions. This part of the gene is shown to encode a C-terminal isoform (with an alternative transcription start site) expressed in the human brain. Consistent with our genetic data, suppression of auts2 in zebrafish embryos caused microcephaly that could be rescued by either the full-length or the C-terminal isoform of AUTS2. Our observations demonstrate a causal role of AUTS2 in neurocognitive disorders, establish a hitherto unappreciated syndromic phenotype at this locus, and show how transcriptional complexity can underpin human pathology. The zebrafish model provides a valuable tool for investigating the etiology of AUTS2 syndrome and facilitating gene-function analysis in the future. PMID:23332918

The syndrome of congenital hypoparathyroidism, mental retardation, facial dysmorphism and extreme growth failure (HRD or Sanjad-Sakati syndrome; OMIM 241410) is an autosomal recessive disorder reported almost exclusively in Middle Eastern populations. A similar syndrome with the additional features of osteosclerosis and recurrent bacterial infections has been classified as autosomal recessive Kenny-Caffey syndrome (AR-KCS; OMIM 244460). Both traits have previously been mapped to chromosome 1q43-44 (refs 5,6) and, despite the observed clinical variability, share an ancestral haplotype, suggesting a common founder mutation. We describe refinement of the critical region to an interval of roughly 230 kb and identification of deletion and truncation mutations of TBCE in affected individuals. The gene TBCE encodes one of several chaperone proteins required for the proper folding of alpha-tubulin subunits and the formation of alpha-beta-tubulin heterodimers. Analysis of diseased fibroblasts and lymphoblastoid cells showed lower microtubule density at the microtubule-organizing center (MTOC) and perturbed microtubule polarity in diseased cells. Immunofluorescence and ultrastructural studies showed disturbances in subcellular organelles that require microtubules for membrane trafficking, such as the Golgi and late endosomal compartments. These findings demonstrate that HRD and AR-KCS are chaperone diseases caused by a genetic defect in the tubulin assembly pathway, and establish a potential connection between tubulin physiology and the development of the parathyroid.

2012-01-01

Williams-Beuren syndrome is a rare familial multisystem disorder occurring in 1 per 20,000 live births. It is characterized by congenital heart defects (CHD), skeletal and renal anomalies, cognitive disorder, social personality disorder and dysmorphic facies. We present a case of Williams syndrome that presented to us with heart murmur and cognitive problem. A 5-year-old girl referred to pediatric cardiologist because of heart murmurs. She had a systolic murmur (2-3/6) in right upper sternal border with radiation to right cervical region. She also had a bulge forehead. Angiography showed mild supra valvular aortic stenosis and mild multiple peripheral pulmonary stenosis. Fluorescent in situ hybridization (FISH) was performed and the result was: 46.XX, ish del (7q11.2) (ELN X1) (7q22 X2) ELN deletion compatible with Williams syndrome. Peripheral pulmonary artery stenosis is associated with Noonan syndrome, Alagille syndrome, Cutis laxa, Ehler-Danlos syndrome, and Silver-Russel syndrome. The patient had peripheral pulmonary artery stenosis, but no other signs of these syndromes were present, and also she had a supravalvular aortic stenosis which was not seen in other syndromes except Williams syndrome. Conclusion. According to primary symptoms, paraclinical and clinical finding such as dysmorphic facies, cognitive disorder and congenital heart defect, Williams syndrome was the first diagnosis. We suggest a more attention for evaluating heart murmur in childhood period, especially when the patient has abnormal facial features or mental problem.

3M syndrome: a report of four cases in two families.

Güven, Ayla; Cebeci, Ayşe Nurcan

2011-01-01

3M syndrome is a rare entity characterized by severe growth retardation, dysmorphic features and skeletal changes as its major components. It is differentiated from other types of dwarfism by its clinical features and by the typical slender long bones and foreshortened vertebral bodies that can be visualized radiographically. 3M syndrome has an autosomal recessive mode of inheritance. An early diagnosis is important for genetic counseling. In this report, we present four children (3 males, 1 female) from two families who were aged between 4(11/12) and 10(11/12) years and had clinical findings of 3M syndrome. One of these patients had received growth hormone (GH) treatment which was discontinued due to an inadequate height gain. Physicians should be aware of this entity in the differential diagnosis of children with severe short stature and mild skeletal changes.

We report a patient with multiple dysmorphic signs and congenital malformations, representing a combination of clinical features of duplication (12p) and deletion (22)(q11.2) syndromes. The girl had overgrowth at birth, showed abnormal cranio-facial findings, cleft uvula, a complex conotruncal heart defect, a polycystic right kidney, and an umbilical hernia. She died at the age of 6 months of cardio-respiratory failure. Cytogenetic examination demonstrated a derivative chromosome 12 replacing one of the two chromosomes 22. The paternal karyotype was normal 46,XY while the mother's karyotype was 46,XX,rcp(12;22)(q13.2;q11.2). According to the published data, all patients with deletion 22q11.2 combined with other unbalanced chromosomal aberration have a more severe clinical expression than those with interstitial deletions.

Partial monosomy 21 results in a great variability of clinical features that may be associated with the size and location of the deletion. In this study, we report a 22-month-old girl who showed a 45,XX,add(12)(p13)dn,-21 karyotype. The final cytogenomic result was 45,XX,der(12)t(12;21)(p13;q22.11) dn,-21.arr[hg19] 21q11.2q22.11(14824453_33868129)×1 revealing a deletion from 21pter to 21q22.11. Clinical manifestation of the patient included hypertonia, a long philtrum, epicanthic folds, low-set ears, and café-au-lait macules - a phenotype considered as mild despite the relatively large size of the deletion compared to patients from the literature. © 2017 S.

The child with developmental delay: An approach to etiology

PubMed Central

Meschino, Wendy S

2003-01-01

OBJECTIVE: To describe an approach to history, physical examination and investigation for the developmentally delayed child. METHODS: A review of electronic databases from 1997 to 2001 was done searching for articles relating to the approach to or investigations of children with developmental delay. Five studies, including a review of a consensus conference on evaluation of mental retardation, were chosen because of their general approaches to developmental delay and/or mental retardation, or specific evaluations of a particular laboratory investigation. CONCLUSIONS: A diagnosis or cause of mental retardation can be identified in 20% to 60% of cases. Evaluation of the developmentally delayed child should include a detailed history and physical examination, taking special care to record a three-generation pedigree, as well as to look for dysmorphic features. If no other cause is apparent, routine investigations should include a chromosome study and fragile X studies. Further investigations are warranted depending on the clinical features. PMID:20011550

3M Syndrome: A Report of Four Cases in Two Families

PubMed Central

Cebeci, Ayşe Nurcan

2011-01-01

3M syndrome is a rare entity characterized by severe growth retardation, dysmorphic features and skeletal changes as its major components. It is differentiated from other types of dwarfism by its clinical features and by the typical slender long bones and foreshortened vertebral bodies that can be visualized radiographically. 3M syndrome has an autosomal recessive mode of inheritance. An early diagnosis is important for genetic counseling. In this report, we present four children (3 males, 1 female) from two families who were aged between 411/12 and 1011/12 years and had clinical findings of 3M syndrome. One of these patients had received growth hormone (GH) treatment which was discontinued due to an inadequate height gain. Physicians should be aware of this entity in the differential diagnosis of children with severe short stature and mild skeletal changes. Conflict of interest:None declared. PMID:21911330

Blum, Austin W; Redden, Sarah A; Grant, Jon E

2018-03-01

Despite reasonable knowledge of body dysmorphic disorder (BDD), little is known of its cognitive antecedents. In this study, we evaluated executive functioning and decision-making in people at risk of developing BDD using neuropsychological tests. Participants were non-treatment seeking volunteers (18-29 years) recruited from the general community, and split into two groups: those "at risk" of developing BDD (N = 5) and controls (N = 82). Participants undertook the One-Touch Stockings of Cambridge, Cambridge Gamble and Spatial Working Memory tasks and were assessed with the Body Dysmorphic Disorder Questionnaire. Results showed that the at-risk subjects performed significantly worse on a measure of executive function, whereas measures of risk-seeking behavior, quality of decision-making, and spatial working memory were largely intact. The findings suggest that selective cognitive dysfunction may already be present in terms of executive functioning in those at risk of developing BDD, even before psychopathology arises.

Giant cell lesions with a Noonan-like phenotype: a case report.

2007-05-01

The purpose of this article is to describe a case of multiple giant cell lesions of the mandible that occurred in a 14-year-old girl with phenotypic characteristics associated with Noonan Syndrome (NS). NS is a dysmorphic disorder characterized by hypertelorism, short stature, congenital heart defects, short and webbed neck, skeletal anomalies, and bleeding diathesis. A 14-year-old girl with a previous diagnosis of NS (sporadic case) presented with multiple radiolucent lesions in the body and ramus of her mandible. In terms of clinical behavior and the described radiographic characteristics, giant cells lesions with Noonan-like phenotype can be considered a form of cherubism. Therefore, surgical intervention is not necessary, but radiographic follow-up and observation is very important during the control and gradual regression of the lesions.

Background Mutations in KCNJ2, the gene encoding the human inward rectifier potassium channel Kir2.1 (IK1 or IKir2.1), have been identified in Andersen-Tawil syndrome (ATS). ATS is a multisystem inherited disease exhibiting periodic paralysis, cardiac arrhythmias, and dysmorphic features at times mimicking catecholaminergic polymorphic ventricular tachycardia (CPVT). Methods and Results Our proband displayed dysmorphic features including micrognathia, clinodactyly and syndactyly, and exhibited multiform extrasystoles and bidirectional ventricular tachycardia both at rest and during exercise testing. The patient’s symptoms continued following administration of nadolol, but subsided after treatment with flecainide. Molecular genetic screening revealed a novel heterozygous mutation (c.779G>C/p.R260P) in KCNJ2. Whole-cell patch-clamp studies conducted in TSA201 cells transfected with wild type human KCNJ2 cDNA (WT-KCNJ2) yielded robust IKir2.1, but no measurable current in cells expressing the R260P mutant. Co-expression of WT and R260P-KCNJ2 (heterozygous expression) yielded a markedly reduced inward IKir2.1 compared with WT alone (−36.5±9.8 pA/pF vs. −143.5±11.4 pA/pF, n=8 for both, P<0.001, respectively at −90 mV) indicating a strong dominant negative effect of the mutant. The outward component of IKir2.1 measured at −50 mV was also markedly reduced with the heterozygous expression vs. WT (0.52±5.5 pA/pF vs. 23.4±6.7 pA/pF, n=8 for both, P<0.001, respectively). Immunocytochemical analysis indicates that impaired trafficking of R260P-KCNJ2 channels. Conclusions We report a novel de novo KCNJ2 mutation associated with classical phenotypic features of ATS and CPVT mimicry. The R260P mutation produces a strong dominant negative effect leading to marked suppression of IK1 secondary to a trafficking defect. PMID:21148745

4p- syndrome and 9p tetrasomy mosaicism with cleft lip and palate.

Chromosome 4p- syndrome is a multiple malformation syndrome associated with partial deletion of the short arm of chromosome 4 (4p-). It is characterized by dysmorphic features and retarded development. Cleft lip and/or palate are the major clinical manifestations. Cases of tetrasomy 9p are extremely rare; the principal clinical manifestations of this condition are characteristic craniofacial abnormalities, generalized hypotonia and severe mental retardation. We present the first case of a female infant with 4p deletion and tetrasomy 9p mosaicism, exhibiting a left-sided cleft lip, alveolus and soft palate. Karyotype analysis of lymphocytes cultured from the patient revealed that she was mosaic: 86% of the cells were 46, XX, add (4) (p15.32) and 14% were 47, XX, add (4) (p15.32), +idic (9)(q12). The G-banding pattern appeared consistent with either translocation or partial proximal deletion of 4p. In order to make a definitive cytogenetic diagnosis of isodicentric chromosome 9, fluorescence in situ hybridization (FISH) was applied. At 8 months, when the patient weighed 4.3 kg, her cleft lip was repaired. Before and after surgery there were no seizures, and the postoperative course was uneventful.

Bello, Sabina; Rodríguez-Moreno, Antonio

The Monosomy 1p36 deletion syndrome is part of the group of diseases known as Rare Diseases. The objective of the present work is to review the characteristics of Monosomy 1p36 deletion syndrome. The monosomy 1p36 deletion syndrome phenotype includes: dysmorphic craniofacial features; large anterior fontanelle, unibrow, deep-set eyes, epicanthus, wide nasal root/bridge, mandible hypoplasia, abnormal location of the pinna, philtrum and pointed chin; neurological alterations: seizures and hydrocephalus (in some cases). Cerebral malformations: ventricular hypertrophy, increased subarachnoid space, morphological alterations of corpus callosum, cortical atrophy, delays in myelinisation, periventricular leukomalacia and periventricular heterotopia. These alterations produce intellectual disability and delays in motor growth, communication skills, language, social and adaptive behaviour. It is Hearing and vision impairments are also observed in subjects with this syndrome, as well as alterations of cardiac, endocrine and urinary systems and alterations at skin and skeletal level. Approximately 100 cases have been documented since 1981. This rare disease is the most common subtelomeric-micro-deletion syndrome. In situ hybridization with fluorescence (FISH) and array-comparative genomic hybridization (CGH-array) are at present the two best diagnostic techniques. There is currently no effective medical treatment for this disease. Copyright © 2016 Sociedad Chilena de Pediatría. Publicado por Elsevier España, S.L.U. All rights reserved.

Proper epigenetic regulation processes are crucial in the normal development of the human brain. An ever-increasing group of neurodevelopmental disorders due to derangements of epigenetic regulation involve both microdeletion and monogenic syndromes. Some of these syndromes have overlapping clinical phenotypes due to haploinsufficiency-sensitive genes involved in microdeletions. It was shown recently that the ZMYND11 gene has important functions in epigenetic regulation as an unconventional transcription co-repressor of highly expressed genes, possibly acting in the repression of cryptic transcription from gene bodies. The aim of our study was to compare the clinical phenotypes of patients with 10p15.3 deletions with the phenotypes of patients with loss-of-function ZMYND11 mutations. The results of our study further confirm that the ZMYND11 gene is the critical gene for the clinical phenotype of 10p15.3 microdeletion involving the terminal ~4 Mb of chromosome 10p. In addition, accumulating clinical data allow for further characterisation of this syndrome, including neurodevelopmental disorder, characteristic dysmorphic features and some other more frequent symptoms, such as behavioural disturbances, hypotonia, seizures, low birth weight, short stature in those older than 10 years of age, genitourinary malformations and recurrent infections.

Pathogenic variants of ACAN have been reported to cause spondyloepiphyseal dysplasia Kimberley type, spondyloepimetaphyseal dysplasia, familial osteochondritis dissecans and idiopathic short stature with normal to advanced bone age. A recent international cohort study significantly expanded the ACAN mutation spectrum, further delineated the heterogeneous clinical characteristics of ACAN mutation patients. The prevalence of ACAN mutation in short stature patients is yet unknown. Here we set to assess the frequency of ACAN variants among a cohort of 218 Chinese children with non-syndromic short stature. We identified three novel truncating variants at the 5' end of ACAN gene. All these pathogenic variants co-segregate with severe short stature phenotype in families. In addition, none of the probands showed significant advanced bone age. All affected individuals showed no signs of significant dysmorphic features or skeletal abnormities. The prevalence of ACAN defect in this cohort is estimated to be 1.4% (3/218). It is higher among families with parents also affected with severe short stature, up to 7.0% (3/43) if parental height is <2.5 SD or 16.7% (3/18) if parental height is <3.0 SD. Our data suggest that ACAN mutation is a relative common cause of familial severe short stature. Copyright © 2017 Elsevier B.V. All rights reserved.

Beauty and the beast: Psychobiologic and evolutionary perspectives on body dysmorphic disorder.

PubMed

Stein, Dan J; Carey, Paul D; Warwick, James

2006-06-01

Body dysmorphic disorder (BDD) is characterized by preoccupation with a defect in appearance. Concepts of beauty play a particularly crucial role in humans' mental and social life, and may have specific psychobiologic and evolutionary underpinnings. In particular, there is a growing literature on the neurocircuitry underpinning the body schema, body image and facial expression processing, and aesthetic and symmetry judgments. Speculatively, disruptions in cognitive-affective processes relevant to judgements about physical beauty lead to BDD.

Body dysmorphic disorder in the dermatology patient.

PubMed

Koblenzer, Caroline S

Body dysmorphic disorder is primarily a psychiatric disorder, in which the patient believes that some normal or very near normal aspect of his or her physical appearance is distorted or ugly. Should there be a minor abnormality, it is grossly exaggerated in the mind of the patient, causing feelings of shame and embarrassment and leading daily to spending hours at the mirror, or any reflecting surface, as the patient tries to conceal or remove the perceived abnormality through the development of ritualistic behavior. Although other organs can be involved-for example, the shape of the nose or a portion of an ear- the skin, hair, and nails are most commonly involved, while the patient constantly seeks reassurance about appearance from friends and family. There is a broad spectrum of severity in body dysmorphic disorder, ranging from obsessional worry to frank delusion, and the psychiatric comorbidities-anxiety, depression, and personality disorder-are prominent parts of the picture. Unfortunately, the psychiatric comorbidities and the negative impact on every aspect of the patient's life may not be recognized by dermatologists and other non-psychiatric physicians, so that effective treatment is often not instituted or appropriate referrals made. This paper describes the incidence, possible etiologies, and clinical picture of body dysmorphic disorder in dermatology patients and discusses interpersonal approaches that may permit appropriate treatment or referral to take place. Specific treatments and prognosis are also discussed. Copyright © 2017 Elsevier Inc. All rights reserved.

Impairment of different protein domains causes variable clinical presentation within Pitt-Hopkins syndrome and suggests intragenic molecular syndromology of TCF4.

Pitt-Hopkins syndrome is a neurodevelopmental disorder characterized by severe intellectual disability and a distinctive facial gestalt. It is caused by haploinsufficiency of the TCF4 gene. The TCF4 protein has different functional domains, with the NLS (nuclear localization signal) domain coded by exons 7-8 and the bHLH (basic Helix-Loop-Helix) domain coded by exon 18. Several alternatively spliced TCF4 variants have been described, allowing for translation of variable protein isoforms. Typical PTHS patients have impairment of at least the bHLH domain. To which extent impairment of the remaining domains contributes to the final phenotype is not clear. There is recent evidence that certain loss-of-function variants disrupting TCF4 are associated with mild ID, but not with typical PTHS. We describe a frameshift-causing partial gene deletion encompassing exons 4-6 of TCF4 in an adult patient with mild ID and nonspecific facial dysmorphisms but without the typical features of PTHS, and a c.520C > T nonsense variant within exon 8 in a child presenting with a severe phenotype largely mimicking PTHS, but lacking the typical facial dysmorphism. Investigation on mRNA, along with literature review, led us to suggest a preliminary phenotypic map of loss-of-function variants affecting TCF4. An intragenic phenotypic map of loss-of-function variants in TCF4 is suggested here for the first time: variants within exons 1-4 and exons 4-6 give rise to a recurrent phenotype with mild ID not in the spectrum of Pitt-Hopkins syndrome (biallelic preservation of both the NLS and bHLH domains); variants within exons 7-8 cause a severe phenotype resembling PTHS but in absence of the typical facial dysmorphism (impairment limited to the NLS domain); variants within exons 9-19 cause typical Pitt-Hopkins syndrome (impairment of at least the bHLH domain). Understanding the TCF4 molecular syndromology can allow for proper nosology in the current era of whole genomic investigations. Copyright © 2017. Published by Elsevier Masson SAS.

A new case of trisomy 19q13.2-->qter is described in a male child which was caused by a maternal balanced translocation (13;19)(p13;q13.2). The major clinical features detected in the patient included the following: facial dysmorphism, bilateral coloboma, narrow and hypoplastic nails, cardiac malformations (Fallot's tetralogy), genitourinary and gastrointestinal anomalies, and agenesis of the corpus callosum. A comparison with other reported cases of partial trisomy 19q is presented. A hypothesis is proposed to account for the involvement of p13 regions of different acrocentrics in some cases of familial translocations involving a chromosome 19. Images PMID:8411060

MRPS22 gene defect is a very rare newly discovered mitochondrial disorder. We report a 4-month-old severely affected male infant with MRPS22 mutation. Whole exome sequencing revealed a novel homozygous splicing mutation c.339 + 5 G > A in MRPS22 gene. He has mild dysmorphism, hypotonia, developmental delay but not hypertrophic cardiomyopathy and tubulopathy which differ from other majority of reported patients. Therefore, hypertrophic cardiomyopathy and tubulopathy may not be considered as constant features of MRPS22. With this case report, we also present first symmetrical bilateral brainstem and medial thalamic lesions, and cerebellar and cerebral atrophy on a brain MR imaging follow-up of ten months.

The clinical and radiological findings are consistent with former descriptions of microcephalic osteodysplastic primordial dwarfism (MOPD) type I/III. In addition to previously published features, multiple fractures of the long bones, severe neonatal cholestasis, and histological dysplasia of the kidneys were found.

Missense MECP2 variants can have various phenotypic effects ranging from a normal phenotype to typical Rett syndrome (RTT). In females, the phenotype can also be influenced by the X-inactivation pattern. In this study, we present detailed clinical descriptions of six patients with a rare base-pair substitution affecting Arg309 at the C-terminal end of the transcriptional repression domain (TRD). All patients have intellectual disability and present with some RTT features, but they do not fulfill the clinical criteria for typical or atypical RTT. Most of the patients also have mild facial dysmorphism. Intriguingly, the mother of an affected male patient is an asymptomatic carrier of this variant. It is therefore likely that the p.(Arg309Trp) variation does not necessarily lead to male lethality, and it results in a wide range of clinical features in females, probably influenced by different X-inactivation patterns in target tissues. © 2016 John Wiley & Sons A/S.

2009-01-01

Lysosomal storage disorders are rare inborn errors of metabolism, with a combined incidence of 1 in 1500 to 7000 live births. These relatively rare disorders are seldom considered when evaluating a sick newborn. A significant number of the >50 different lysosomal storage disorders, however, do manifest in the neonatal period and should be part of the differential diagnosis of several perinatal phenotypes. We review the earliest clinical features, diagnostic tests, and treatment options for lysosomal storage disorders that can present in the newborn. Although many of the lysosomal storage disorders are characterized by a range in phenotypes, the focus of this review is on the specific symptoms and clinical findings that present in the perinatal period, including neurologic, respiratory, endocrine, and cardiovascular manifestations, dysmorphic features, hepatosplenomegaly, skin or ocular involvement, and hydrops fetalis/congenital ascites. A greater awareness of these features may help to reduce misdiagnosis and promote the early detection of lysosomal storage disorders. Implementing therapy at the earliest stage possible is crucial for several of the lysosomal storage disorders; hence, an early appreciation of these disorders by physicians who treat newborns is essential.

To highlight Noonan syndrome as a clinically recognizable cause of severe to profound sensorineural hearing impairment. New clinical cases and review. Patients evaluated for etiological diagnosis by a medical geneticist in a reference center for hearing impairment. Five patients presenting with confirmed Noonan syndrome and profound sensorineural hearing impairment. Diagnostic and review of the literature. Five patients presented with profound sensorineural hearing impairment and molecularly confirmed Noonan syndrome. Sensorineural hearing impairment has been progressive for three patients. Cardiac echography identified pulmonary stenosis in two patients and was normal for the three other patients. Short stature was found in two patients. Mild intellectual disability was found in one patient. Inconspicuous clinical features as facial dysmorphism, cryptorchidism, or easy bruising were of peculiar interest to reach the diagnosis of Noonan syndrome. Profound sensorineural hearing impairment can be the main feature of Noonan syndrome. Associated features are highly variable; thus, detailed medical history and careful physical examination are mandatory to consider the diagnosis in case of a sensorineural hearing impairment.

Deletion of 2q24.2 is a rare cytogenetic aberration in patients, exhibiting heterogeneous clinical features, and common phenotypes included developmental delay, intellectual disability, hypotonia, and mild dysmorphic features. Hearing impairment and anal atresia are rarely described. Here we described a 9-month-old female patient with hypotonia in all four limbs, developmental delay, and intellectual disability. In addition, congenital anal atresia was diagnosed and treated after birth, and hearing impairment was found in right ear. Single nucleotide polymorphisms (SNP) array detected a 5.2 Mb deletion on 2q24.2q24.3, including 19 genes (ITGB6; TBR1; SLC4A10; KCNH7 SCN3A; SCN2A et al.). Among these genes, it is affirmative that TBR1 is a causative gene for intellectual disability; however, the pathogenic genes of other phenotypes remain unclear. We briefly review the knowledge of genes likely involved in these clinical features, including hearing impairment, anal atresia, and developmental delay. Copyright © 2018 Elsevier B.V.

Prevalence and characteristics of the continuum of diagnoses within fetal alcohol spectrum disorders (FASD) were researched in previously unstudied rural, agricultural, lower socioeconomic populations in South Africa (ZA). Using an active case ascertainment approach among first grade learners, 1354 (72.6%) were consented into the study via: height, weight, and/or head circumference ≤ 25th centile and/or random selection as normal control candidates. Final diagnoses were made following: examination by pediatric dysmorphologists/geneticists, cognitive/behavioral testing, and maternal risk factor interviews. FASD children were significantly growth deficient and dysmorphic: physical measurements, cardinal facial features of FAS, and total dysmorphology scores clearly differentiated diagnostic categories from severe to mild to normal in a consistent, linear fashion. Neurodevelopmental delays were also significantly worse for each of the FASD diagnostic categories, although not as consistently linear across groups. Alcohol use is well documented as the proximal maternal risk factor for each diagnostic group. Significant distal maternal risk factors in this population are: low body weight, body mass, education, and income; and high gravidity, parity, and age at birth of the index child. In this low SES, highly rural region, FAS occurs in 93-128 per 1000 children, PFAS in 58-86, and, ARND in 32-46 per 1000. Total FASD affect 182-259 per 1000 children or 18-26%. Very high rates of FASD exist in these rural areas and isolated towns where entrenched practices of regular binge drinking co-exist with challenging conditions for childbearing and child development.

Although body image is central to the etiological models of anorexia nervosa and body dysmorphic disorder, studies comparing body image and beliefs about attractiveness between the disorders are rare. Sixty-nine individuals (anorexia nervosa: n=24, body dysmorphic disorder: n=23, healthy controls: n=22) completed self-report measures (body image and general psychopathology), diagnostic interviews, and Go/No-Go Association tasks measuring implicit associations. Compared to controls, both clinical groups exhibited greater negative body image, a more negative attitude toward their physical selves, and more dysfunctional coping strategies (ps<.001). Also, both clinical groups shared greater explicit beliefs about the importance of attractiveness (ps<.001). In addition to supporting previous research with regard to comparable body image disturbance, this study also showed that beliefs regarding the importance of appearance (e.g., "one must be attractive to be successful") might be a fruitful target for therapy across both disorders.

Javanbakht, M; Nazari, A; Javanbakht, A; Moghaddam, L

2012-02-01

There has been increasing number of requests for cosmetic rhinoplastic surgery among Iranian people in different age groups in recent years. One risk for people who undergo such plastic operations is the presence of body dysmorphic disorder (BDD), which can complicate the result and decrease the rate of satisfaction from surgery. This study aimed to investigate mental health problems in people seeking rhinoplastic surgery. In this case-control study, the scores of General Health Questionnaire (GHQ) and DCQ (Dysmorphic Concerns Questionnaire) were obtained from 50 individuals who were candidates for rhinoplasty, and the results were compared with a normal control group. The total GHQ score and scores in anxiety, depression, and social dysfunction sub-scales were higher among the study group. This was the same for the DCQ score. However, the scores of somatization sub-scale of GHQ were not significantly different between the two groups. Psychiatric evaluation of candidates for rhinoplasty seems necessary for prevention of unnecessary and repetitive surgical operations.

This submission presents a case of scoliosis in a patient with established Dandy-Walker anomaly of the brain. A retrospective review of the patient's case notes was undertaken and the limited literature on this subject reviewed. The 13-year-old girl presented with a stiff right thoracic scoliosis typical of adolescent idiopathic scoliosis. The scoliotic segment also presented with significant lordosis. She had facial and truncal dysmorphism characteristic of Dandy-Walker complex and her brain images confirmed the diagnosis. She underwent scoliosis surgery by the posterior approach uneventfully. In conclusion scoliosis is hitherto unreported in the Dandy-Walker complex. The results of intervention appear satisfactory.

Congenital hepatic fibrosis in a child with Prader-Willi syndrome: a novel association.

Prader-Willi syndrome (PWS) is a rare genetic disorder caused by deletion or unexpression of the chromosome 15 (q 11-13). Symptomatologies include hypotonia, hyperphagia, cognitive impairment, and characteristic dysmorphic profile. Here, we report a 4-year-old boy with PWS who presented with complications of congenital hepatic fibrosis. The uniparental heterodisomy makes it unlikely that the hepatic fibrosis was caused by unmasking of a recessive mutation on the maternal chromosome 15 although we cannot exclude the possibility of a recessively inherited mutation elsewhere given the parental consanguinity. This is the first report of congenital hepatic fibrosis in PWS.

Loss-of-function variants in NFIA provide further support that NFIA is a critical gene in 1p32-p31 deletion syndrome: A four patient series.

The association between 1p32-p31 contiguous gene deletions and a distinct phenotype that includes anomalies of the corpus callosum, ventriculomegaly, developmental delay, seizures, and dysmorphic features has been long recognized and described. Recently, the observation of overlapping phenotypes in patients with chromosome translocations that disrupt NFIA (Nuclear factor I/A), a gene within this deleted region, and NFIA intragenic deletions has led to the hypothesis that NFIA is a critical gene within this region. The wide application and increasing accessibility of whole exome sequencing (WES) has helped identify new cases to support this hypothesis. Here, we describe four patients with loss-of-function variants in the NFIA gene identified through WES. The clinical presentation of these patients significantly overlaps with the phenotype described in previously reported cases of 1p32-p31 deletion syndrome, NFIA gene disruptions and intragenic NFIA deletions. Our cohort includes a mother and daughter as well as an unrelated individual who share the same nonsense variant (c.205C>T, p.Arg69Ter; NM_001145512.1). We also report a patient with a frameshift NFIA variant (c.159_160dupCC, p.Gln54ProfsTer49). We have compared published cases of 1p32-p31 microdeletion syndrome, translocations resulting in NFIA gene disruption, intragenic deletions, and loss-of-function mutations (including our four patients) to reveal that abnormalities of the corpus callosum, ventriculomegaly/hydrocephalus, macrocephaly, Chiari I malformation, dysmorphic features, developmental delay, hypotonia, and urinary tract defects are common findings. The consistent overlap in clinical presentation provides further evidence of the critical role of NFIA haploinsufficiency in the development of the 1p32-p31 microdeletion syndrome phenotype. © 2017 Wiley Periodicals, Inc.

Tetralogy of Fallot associated with deletion in the DiGeorge region of chromosome 22 (22q11)

D`Angelo, J.A.; Pillers, D.M.; Jett, P.L.

Cardiac conotruncal defects, such as Tetralogy of Fallot (TOF), are associated with DiGeorge syndrome which has been mapped to the q11 region of chromosome 22 and includes abnormalities of neural crest and branchial arch development. Patients with conotruncal defects and velo-cardio-facial syndrome may have defects in the 22q11 region but not show the complete DiGeorge phenotype consisting of cardiac, thymus, and parathyroid abnormalities. We report two neonates with TOF and small deletions in the DiGeorge region of chromosome 22 (46,XX,del(22)(q11.21q11.23) and 46,XY,del(22)(q11.2q11.2)) using both high-resolution cytogenetics and fluorescence in situ hybridization (FISH). The first patient is a female with TOFmore » and a family history of congenital heart disease. The mother has pulmonic stenosis and a right-sided aortic arch, one brother has TOF, and a second brother has a large VSD. The patient had intrauterine growth retardation and had thrombocytopenia due to maternal IgG platelet-directed autoantibody. Lymphocyte populations, both T and B cells, were reduced in number but responded normally to stimulation. The findings were not attributed to a DiGeorge phenotype. Although she had transient neonatal hypocalcemia, her parathyroid hormone level was normal. The patient was not dysmorphic in the newborn period but her mother had features consistent with velo-cardio-facial syndrome. The second patient was a male with TOF who was not dysmorphic and had no other significant clinical findings and no family history of heart disease. Lymphocyte testing did not reveal a specific immunodeficiency. No significant postnatal hypocalcemia was noted. These cases illustrate that there is a wide spectrum of clinical features associated with defects of the 22q11 region. We recommend karyotype analysis, including FISH probes specific to the DiGeorge region, in any patient with conotruncal cardiac defects.« less

Patients suffering from body dysmorphic disorder (bdd) are preoccupied with a slight or imagined defect in appearance. First of all, to review the literature on the prevalence of bdd in cosmetic surgery and thereafter to review the literature on psychiatric comorbidity and the outcome of surgical interventions. We based our search strategy on Embase, Medline and PubMed, using the search terms 'body dysmorphic disorder', 'cosmetic surgery', 'prevalence', 'comorbidity' and 'outcome'. Our search covered English and Dutch literature published after the introduction of bdd in dsm-iii-r and before 1 November, 2013. A study of the relevant articles enabled us to access additional articles mentioned in these texts. Our initial search strategy turned out to be too narrow. It was therefore broadened to include 'body dysmorphic disorder', 'cosmetic surgery', and 'prevalence'. Eventually we included 23 original articles. In 11 of these the prevalence of bdd varied from 3.2 to 53.6%. Twelve articles on psychiatric comorbidity revealed predominantly mood and anxiety disorders on axis I and cluster C personality disorders on axis II. Only two studies reported on the outcome of cosmetic surgery performed on bdd patients; surgical interventions, however, seemed to result in new preoccupations with the prolongation of psychiatric comorbidity. bdd is a common psychiatric disorder that can sometimes lead to cosmetic surgery. However, pre-operative screening of bdd patients is vital so that efficient psychiatric treatment can be initiated and patients are not subjected to surgical interventions which may be ineffective or even harmful.

Prevalence of Body Dysmorphic Disorder Among Patients Seeking Breast Reconstruction.

Body dysmorphic disorder (BDD) is characterized by a preoccupation with a slight or imagined defect in physical appearance. It has significant implications for patients who desire breast reconstruction, because patient satisfaction with the aesthetic outcome is a substantial contributor to the success of the procedure. The authors estimated the prevalence of BDD among women seeking breast reconstruction by surveying patients with the previously validated Dysmorphic Concerns Questionnaire (DCQ). One hundred eighty-eight women who presented for immediate or delayed breast reconstruction completed the DCQ anonymously, during initial consultation with a plastic surgeon. Two groups of respondents were identified: those who desired immediate reconstruction and those who planned to undergo delayed reconstruction. The prevalence of BDD among breast reconstruction patients was compared between the 2 groups, and the overall prevalence was compared with published rates for the general public. Body dysmorphic disorder was significantly more prevalent in breast reconstruction patients than in the general population (17% vs 2%; P < .001). It also was much more common among patients who planned to undergo delayed (vs immediate) reconstruction (34% vs 13%; P = .004). Relative to the general public, significantly more women who sought breast reconstruction were diagnosed as having BDD. Awareness of the potential for BDD will enable clinicians to better understand their patients' perspectives and discuss realistic expectations at the initial consultation. Future studies are warranted to examine the implications of BDD on patient satisfaction with reconstructive surgery. 3. © 2014 The American Society for Aesthetic Plastic Surgery, Inc.

Hypoparathyroidism-retardation-dysmorphism syndrome in a girl: A new variant not caused by a TBCE mutation--clinical report and review.

Hypoparathyroidism-retardation-dysmorphism (HRD) or Sanjad-Sakati syndrome (SSS) (OMIM 241410) is a rare autosomal recessive (AR) inherited condition, characterized by congenital hypoparathyroidism (hypoPTH), retardation, seizures, and a typical facial dysmorphism, consisting of prominent forehead, deep-set eyes, and abnormal external ears. This disorder has been mapped to the long arm of chromosome 1 (1q42-q43) and mutations in the gene coding for tubulin-specific chaperone E (TBCE) have been identified as the cause of the disease. Mutations in the same gene were also reported in patients with AR Kenny-Caffey syndrome (KCS). We report on a 41/2-year-old girl with congenital hypoPTH, seizures, developmental delay, and a facial dysmorphism, compatible with HRD syndrome. Mutation analyses revealed no mutations in the TBCE gene. In addition, normal TBCE protein and alpha-tubulin immunostaining were observed in a lymphoblastoid line derived from the patient, excluding the TBCE gene as the causative gene of the syndrome in this patient. A de novo microduplication of probe RP11-262I1 on 4q35 in the proposita was detected by microarray analyses, but this could not be confirmed by additional studies. We review and discuss the clinical findings of our case and those of the other reported cases with SSS and AR KCS. We conclude that a second gene locus for this disorder seems probable and that 4q35 needs further evaluation as a candidate region.

Our aim was to investigate the impact of comorbid body dysmorphic disorder (BDD) on the response to sequential pharmacological trials in adult obsessive-compulsive disorder (OCD) patients. The sequential trial initially involved fluoxetine monotherapy followed by one of three randomized, add-on strategies: placebo, clomipramine or quetiapine. We included 138 patients in the initial phase of fluoxetine, up to 80 mg or the maximum tolerated dosage, for 12 weeks. We invited 70 non-responders to participate in the add-on trial; as 54 accepted, we allocated 18 to each treatment group and followed them for an additional 12 weeks. To evaluate the combined effects of sex, age, age at onset, initial severity, type of augmentation and BDD on the response to sequential treatments, we constructed a model using generalized estimating equations (GEE). Of the 39 patients who completed the study (OCD-BDD, n = 13; OCD-non-BDD, n = 26), the OCD-BDD patients were less likely to be classified as responders than the OCD-non-BDD patients (Pearson Chi-Square = 4.4; p = 0.036). In the GEE model, BDD was not significantly associated with a worse response to sequential treatments (z-robust = 1.77; p = 0.07). The predictive potential of BDD regarding sequential treatment strategies for OCD did not survive when the analyses were controlled for other clinical characteristics. © The Author(s) 2013.

Escalation from normal appearance related intrusive cognitions to clinical preoccupations in Body Dysmorphic Disorder: A cross-sectional study.

PubMed

Giraldo-O'Meara, Martha; Belloch, Amparo

2018-07-01

Current cognitive approaches to Body Dysmorphic Disorder (BDD) assume that appearance-related intrusive cognitions and their functional consequences characterize the disorder, in a similar way that obsessive intrusive thoughts characterize the Obsessive-Compulsive Disorder (OCD). This study explores whether normal but unwanted appearance-related intrusive thoughts (AITs), escalate to clinical AITs when they are dysfunctionally appraised and instigate counterproductive neutralizing strategies. From a sample of 344 non-clinical individuals who reported a highly upsetting AIT during the past three months two subgroups were extracted according to their high (n = 68) and low (n = 276) vulnerability to BDD. The subjects in the high-risk group obtained significantly higher scores on the frequency of the most disturbing AIT and its emotional impact, interference, and appraisals evaluated with the Appearance Intrusions Questionnaire (AIQ). Additionally, two subgroups of 15 subjects each, with high and low risk to BDD, were formed and their scores were compared to 10 patients with BDD. The AIT had a greater emotional negative impact and more severe consequences on individuals with BDD compared to individuals at high-risk of BDD, which in turn, reported worse consequences of the AIT than those at low-risk. These results empirically support the similarities between BDD and OCD regarding their functional and phenomenological characteristics. Copyright © 2018 Elsevier B.V. All rights reserved.

Trisomy X (47,XXX) is a gonosomal aneuploidy characterized by the presence of an extra X chromosome in a female person. Usually the diagnosis is established made postnatally by chromosome analysis in patients with suggestive clinical signs. Clinical signs vary by age. In prepubertal patients have a growth retardation associated with uncharacteristic facial dysmorphism, mild mental retardation with behavioral disorders, plus clinical signs of ovarian dysgenesis, postpubertal. We analyzed retrospectively the genotype - phenotype correlations for a selected group of 36 patients diagnosed with trisomy X (homogeneous or mosaic) by cytogenetic methods (X chromatin and karyotype). Analysis of the clinical data of 36 patients diagnosed with trisomy X and correlation with the results of X chromatin and karyotype. Clinical signs detected in patients with homogeneous trisomy X 47,XXX (22.22%), mosaic 46,XX/47,XXX (16.66%) or 47,XXX/48,XXXX (5.55%) were prepubertal, growth retardation associated with dysmorphic facial (upslanted palpebral fissure, epichantus, thin lips) and postpubertal, signs of ovarian dysgenesis (secondary amenorrhea, early menopause). The phenotype of patients with different gonosomal mosaic corresponding to Turner syndrome, incorporating a cell line with trisomy X (55.55%) was variable, correlated with the type of chromosomal abnormalities detected. The results of our study are similar to those obtained in other studies and emphasizes that phenotypic variability of patients with trisomy X feature makes it difficult to genotype - phenotype correlations.

Williams-Beuren syndrome is a rare familial multisystem disorder occurring in 1 per 20,000 live births. It is characterized by congenital heart defects (CHD), skeletal and renal anomalies, cognitive disorder, social personality disorder and dysmorphic facies. We present a case of Williams syndrome that presented to us with heart murmur and cognitive problem. A 5-year-old girl referred to pediatric cardiologist because of heart murmurs. She had a systolic murmur (2-3/6) in right upper sternal border with radiation to right cervical region. She also had a bulge forehead. Angiography showed mild supra valvular aortic stenosis and mild multiple peripheral pulmonary stenosis. Fluorescent in situ hybridization (FISH) was performed and the result was: 46.XX, ish del (7q11.2) (ELN X1) (7q22 X2) ELN deletion compatible with Williams syndrome. Peripheral pulmonary artery stenosis is associated with Noonan syndrome, Alagille syndrome, Cutis laxa, Ehler-Danlos syndrome, and Silver-Russel syndrome. The patient had peripheral pulmonary artery stenosis, but no other signs of these syndromes were present, and also she had a supravalvular aortic stenosis which was not seen in other syndromes except Williams syndrome. Conclusion. According to primary symptoms, paraclinical and clinical finding such as dysmorphic facies, cognitive disorder and congenital heart defect, Williams syndrome was the first diagnosis. We suggest a more attention for evaluating heart murmur in childhood period, especially when the patient has abnormal facial features or mental problem. PMID:22927862

2015-10-01

Gorlin-Goltz syndrome is an underdiagnosed autosomal dominant disorder with variable expressivity that is characterized by an increased predisposition to tumorigenesis of multiple types. The major clinical features include multiple basal cell carcinomas (BCCs) appearing in early childhood, palmar and plantar pits, odontogenic keratocysts of the oral cavity, skeletal defects, craniofacial dysmorphism, and ectopic intracranial calcification. The authors present the clinical course of a 12-year-old girl presenting with facial asymmetry and pain because of previously undiagnosed Gorlin-Goltz syndrome. Early diagnosis and attentive management by a multidisciplinary team are paramount to improving outcomes in patients with this disorder, and this report serves as a paradigm for maintaining a high clinical suspicion, which must be accompanied by an appropriate radiologic workup.

Duplication 22q11.2 syndrome is the result of a microduplication of the same chromosomal region that is deleted in DiGeorge and Velocardiofacial syndromes. We describe a patient with dysmorphic features who was diagnosed with pre-B acute lymphoblastic leukemia, and developed cystinuria and pancreatitis during treatment. Duplication 22q11.2 has not been previously described in association with hematologic abnormalities. Chromosomal microarray technology was used to diagnose duplication 22q11.2 syndrome. In this era of advanced genomics, this technology has become an important method for helping to determine the molecular basis of diseases, best treatments and ultimately patient outcomes.

p.(Arg320His) mutation in the KCNC1 gene in human 11p15.1 has recently been identified in patients with progressive myoclonus epilepsies, a group of rare inherited disorders manifesting with action myoclonus, myoclonic epilepsy, and ataxia. This KCNC1 variant causes a dominant-negative effect. Here we describe three patients from the same family with intellectual disability and dysmorphic features. The three affected individuals carry a c.1015C>T (p.(Arg339*)) nonsense variant in KCNC1 gene. As previously observed in the mutant mouse carrying a disrupted KCNC1 gene, these findings reveal that individuals with a KCNC1 loss-of-function variant can present intellectual disability without seizure and epilepsy.

Unal, Sule; Chui, David H K; Gumruk, Fatma

2015-01-01

A 16-year-old boy who was diagnosed to have sickle cell anemia was referred to our center. The parental consanguinity, growth retardation and dysmorphic features prompted a search for possible Fanconi's Anemia (FA). The diepoxybutane (DEB) test was positive, confirming FA. The interaction of both diseases might account for his relatively mild phenotype in terms of both sickle cell anemia (or Hb S, HBB: c.20A > T) and FA. The high Hb F level that might be related to concomitant FA, may have caused a milder phenotype of sickle cell anemia, whereas nitric oxide (NO) depletion as a consequence of sickle cell anemia, may have caused a delay in the bone marrow failure of FA.

1999-05-01

Nance-Horan syndrome (NHS) is an X-linked condition characterised by congenital cataracts, microphthalmia and/or microcornea, unusual dental morphology, dysmorphic facial features, and developmental delay in some cases. Recent linkage studies have mapped the NHS disease gene to a 3.5-cM interval on Xp22.2 between DXS1053 and DXS443. We previously identified a human homologue of a mouse retinoic-acid-induced gene (RAI2) within the NHS critical flanking interval and have tested the gene as a candidate for Nance-Horan syndrome in nine NHS-affected families. Direct sequencing of the RAI2 gene and predicted promoter region has revealed no mutations in the families screened; RAI2 is therefore unlikely to be associated with NHS.

Microcephalic osteodysplastic primordial dwarfism type I (MOPD I) is a rare autosomal recessive developmental disorder characterized by extreme intrauterine growth retardation, severe microcephaly, central nervous system abnormalities, dysmorphic facial features, skin abnormalities, skeletal changes, limb deformations, and early death. Recently, mutations in the RNU4ATAC gene, which encodes U4atac, a small nuclear RNA that is a crucial component of the minor spliceosome, were found to cause MOPD I. MOPD I is the first disease known to be associated with a defect in small nuclear RNAs. We describe here the clinical and molecular data for 17 cases of MOPD I, including 15 previously unreported cases, all carrying biallelic mutations in the RNU4ATAC gene. PMID:21815888

We report on a 2 9/12-year-old boy with disproportionate short stature, microcephaly, subtle craniofacial dysmorphisms, and generalized skeletal dysplasia, who developed a left hemiparesis. Brain neuroimaging disclosed a complex cerebral vascular anomaly (CVA) with stenosis of the right anterior cerebral artery and telangiectatic collateral vessels supplying the cerebral cortex, consistent with moyamoya disease. Based on clinical and skeletal features, a diagnosis of Majewski osteodysplastic primordial dwarfism type II (MOPD II) was established. Review of 16 published patients with CVA affected by either Seckel syndrome or MOPD II suggested that CVA is preferentially associated to the latter subtype affecting about 1/4 of the patients. 2005 Wiley-Liss, Inc.

Spondylo-meta-epiphyseal dysplasia, short limb-abnormal calcification type, is a rare autosomal recessive disorder of the skeleton characterized by disproportionate short stature with narrow chest and dysmorphic facial features. The skeletal manifestations include platyspondyly, short flared ribs, short tubular bones with abnormal metaphyses and epiphyses, severe brachydactyly, and premature stippled calcifications in the cartilage. The abnormal calcifications are so distinctive as to point to the definitive diagnosis. However, they may be too subtle to attract diagnostic attention in infancy. Homozygous variants in DDR2 cause this disorder. We report on a 5-year-old girl with the classic phenotype of SMED, SL-AC in whom a novel homozygous nonsense mutation in DDR2 was detected using exome sequencing.

Trisomy 18 is the second most common chromosomal syndrome and has multiple dysmorphic features. However, ocular findings in trisomy 18 are rarely reported. Retinal folds are the most common ocular finding described to date, although retinal hypopigmentation, dysplasia, and areas of hemorrhage and gliosis are also found in trisomy 18. Dandy-Walker syndrome is a brain malformation that has been reported in association with numerous chromosomal abnormalities, although it has rarely been reported in association with trisomy 18. Here, we present a case of trisomy 18 with ocular pathology and variant of Dandy-Walker syndrome, a combination that has not previously been reported. Copyright © 2010 Taiwan Pediatric Association.

22q11 deletion is one of the most frequently encountered genetic syndromes. The phenotypic spectrum shows a wide variability. We report a boy who presented at age 11.9 years with seizures due to hypocalcemia as a result of hypoparathyroidism. FISH analysis revealed a heterozygote deletion at 22q11.2. Positive findings for the syndrome were delayed speech development due to velofacial dysfunction, recurrent croup attacks in early childhood due to latent hypocalcemia and mild dysmorphic features. The findings of this patient indicate that 22q11 deletion syndrome may present with a wide spectrum of clinical findings and that this diagnosis needs to be considered even in patients of older ages presenting with hypocalcemia.

We report a boy who presented at age 11.9 years with seizures due to hypocalcemia as a result of hypoparathyroidism. FISH analysis revealed a heterozygote deletion at 22q11.2. Positive findings for the syndrome were delayed speech development due to velofacial dysfunction, recurrent croup attacks in early childhood due to latent hypocalcemia and mild dysmorphic features. The findings of this patient indicate that 22q11 deletion syndrome may present with a wide spectrum of clinical findings and that this diagnosis needs to be considered even in patients of older ages presenting with hypocalcemia.

We report the case of a 14-year-old girl with mental retardation and dysmorphic features referred to child psychiatry because of altered behavior at school. Karyotyping (GTG banding), in situ fluorescent hybridization (FISH) and molecular study of parental origin by polymorphic STS were performed. Genetic study revealed a 48,XXXX karyotype with a maternal origin of the X-tetrasomy. The mechanism was successive non-dysjunction at meiosis I and II. The interest of this case lies in the rarity of the chromosomal anomaly and its late diagnosis, leading to a failure to adapt the girl's education to her needs, with consequences for her psyche.

A 45-year-old male was referred for diabetes mellitus. Clinical examination found a family history of multiple precocious deaths, strong consanguinity, personal history of seizures during childhood, small testicles, small penis, sparse body hair, long arms and legs, dysmorphic features, mental retardation, dysarthria, tremor, and mild gait ataxia. Investigations found pigmentary retinitis, metabolic syndrome, unilateral renal aplasia, and hypergonadotropic hypogonadism, and ruled out mitochondrial cytopathy and leucodystrophy. Karyotype study showed a 48XXYY chromosomal type. Renal aplasia and pigmentary retinitis have not been described in 48XXYY patients. They may be related to the chromosomal sex aneuploidy, or caused by other genetic aberrations in light of the high consanguinity rate in the patient's family.

Fetomaternal alloimmune thrombocytopenia (FMAIT) caused by maternal antibodies is the leading cause of severe neonatal thrombocytopenia. A 1-month-old Caucasian girl was referred to our Hematology Clinic for persistent thrombocytopenia diagnosed after a bleeding episode. Diagnostic tests suggested FMAIT. Mild thrombocytopenia persisted for 18 months, and subsequent findings of dysmorphic facies, short stature and mild pulmonary stenosis led to the hypothesis of Noonan syndrome (NS), which was confirmed by genetic test. Other hematological abnormalities were excluded and she had no further bleeding episodes. This case illustrates the possibility of different diagnoses with the same clinical manifestations. The persistence of thrombocytopenia longer than expected associated with typical physical features led to the diagnosis of NS.

We report a six-year-old boy who presented with short stature, microcephaly, dysmorphic features, and developmental delay and who was identified with a terminal deletion of 15q26.2q26.3 containing the insulin-like growth factor receptor (IGF1R) gene in addition to a terminal duplication of the 4q35.1q35.2 region. We compare our case with other reports of deletions and mutations affecting the IGF1R gene associated with pre-and postnatal growth restriction. We report the dramatic response to growth hormone therapy in this patient which highlights the importance of identifying patients with IGF1R deletion and treating them early.

22q11.2 deletion syndrome is a common microdeletion syndrome that affected various systems. To determine clinical phenotypes and immunologicalfeatures of 22q11.2 deletion syndrome in north-eastern Thai children compare to western countries. The authors described the clinical and immunological features in 20 north-eastern Thai children with 22q11.2 deletion syndrome that were followed-up at Srinagarind Hospital. Clinical phenotypes were facial dysmorphism (100%), congenital heart disease (80%) and cleft palate (30%). Prevalence of tetralogy of Fallot (TOF) in this syndrome was higher than in western. Serious infections were found including pneumonia, septicemia and brain abscess. Only a patient had panhypogammaglobulinemia and subsequently died. Selective IgA deficiency was not found. There was a twin patient conceivedfrom intracytoplasmic sperm injection (ICSI). TOF is more common in Asian patients than in western which different to selective IgA deficiency. The 22q11.2 deletion syndrome could be consequence from ICSI.

We described a 5-year-old male with hypodontia, hypohidrosis, and facial dysmorphisms characterized by a depressed nasal bridge, maxillary hypoplasia, and protuberant lips. Chromosomal analysis revealed a normal 46,XY male karyotype. Due to the presence of clinical features of hypohidrotic ectodermal dysplasia (HED), the EDA gene, located at Xq12q13.1, of the patient and his family was sequenced. Analysis of the proband's sequence revealed a missense mutation (T to A transversion) in hemizygosity state at nucleotide position 158 in exon 1 of the EDA gene, which changes codon 53 from leucine to histidine, while heterozygosity at this position was detected in the slightly affected mother; moreover, this mutation was not found in the publically available Human Gene Mutation Database. To date, our findings indicate that a novel mutation in EDA is associated with X-linked HED, adding it to the repertoire of EDA mutations. © 2017 S. Karger AG, Basel.

Co-incidence of Turner syndrome and Duchenne muscular dystrophy - an important problem for the clinician.

Turner syndrome is a relatively common chromosomal disorder which affects about one in 2000 live born females. Duchenne muscular dystrophy is an X-linked recessive disorder affecting 1:3600 live born males. Considering the above, the coexistence of these two diseases may occur only anecdotally. Here, we report a 4 ½ year-old female with classical 45,X Turner syndrome who also had Duchenne muscular dystrophy caused by a point mutation in the dystrophin gene (c.9055delG). The patient showed the typical phenotype of Turner syndrome including distinctive dysmorphic features (short neck, low posterior hairline, wide position of nipples), aortic coarctation and feet lymphedema. Besides, she presented with an unusually early beginning of muscular dystrophy symptoms with infantile-onset motor developmental delay, intellectual disability and early calf muscular hypertrophy. The coexistence of an X-linked recessive disorder should be considered in women affected by Turner syndrome presenting with additional atypical clinical features.

Genetic Forms of Epilepsies and other Paroxysmal Disorders

Genetic mechanisms explain the pathophysiology of many forms of epilepsy and other paroxysmal disorders such as alternating hemiplegia of childhood, familial hemiplegic migraine, and paroxysmal dyskinesias. Epilepsy is a key feature of well-defined genetic syndromes including Tuberous Sclerosis Complex, Rett syndrome, Angelman syndrome, and others. There is an increasing number of singe gene causes or susceptibility factors associated with several epilepsy syndromes, including the early onset epileptic encephalopathies, benign neonatal/infantile seizures, progressive myoclonus epilepsies, genetic generalized and benign focal epilepsies, epileptic aphasias, and familial focal epilepsies. Molecular mechanisms are diverse, and a single gene can be associated with a broad range of phenotypes. Additional features, such as dysmorphisms, head size, movement disorders, and family history may provide clues to a genetic diagnosis. Genetic testing can impact medical care and counseling. We discuss genetic mechanisms of epilepsy and other paroxysmal disorders, tools and indications for genetic testing, known genotype-phenotype associations, the importance of genetic counseling, and a look towards the future of epilepsy genetics.

To compare the detection of facial attributes by computer-based facial recognition software of 2-D images against standard, manual examination in fetal alcohol spectrum disorders (FASD). Participants were gathered from the Fetal Alcohol Syndrome Epidemiology Research database. Standard frontal and oblique photographs of children were obtained during a manual, in-person dysmorphology assessment. Images were submitted for facial analysis conducted by the facial dysmorphology novel analysis technology (an automated system), which assesses ratios of measurements between various facial landmarks to determine the presence of dysmorphic features. Manual blinded dysmorphology assessments were compared with those obtained via the computer-aided system. Areas under the curve values for individual receiver-operating characteristic curves revealed the computer-aided system (0.88 ± 0.02) to be comparable to the manual method (0.86 ± 0.03) in detecting patients with FASD. Interestingly, cases of alcohol-related neurodevelopmental disorder (ARND) were identified more efficiently by the computer-aided system (0.84 ± 0.07) in comparison to the manual method (0.74 ± 0.04). A facial gestalt analysis of patients with ARND also identified more generalized facial findings compared to the cardinal facial features seen in more severe forms of FASD. We found there was an increased diagnostic accuracy for ARND via our computer-aided method. As this category has been historically difficult to diagnose, we believe our experiment demonstrates that facial dysmorphology novel analysis technology can potentially improve ARND diagnosis by introducing a standardized metric for recognizing FASD-associated facial anomalies. Earlier recognition of these patients will lead to earlier intervention with improved patient outcomes. Copyright © 2017 by the American Academy of Pediatrics.

Short stature Revealing a Pycnodysostosis: A Case Report

PubMed Central

Aynaou, Hayat; Skiker, Imane; Latrech, Hanane

2016-01-01

Introduction: Pycnodysostosis is a rare genetic disease characterized by osteosclerosis and bone fragility. The clinical aspects are varied including short stature, acro-osteolysis of distal phalanges, and dysplasia of the clavicles. Oral and maxillofacial manifestations of this disease are very clear. The head is usually large, a beaked nose, obtuse mandibular angle, and both maxilla and mandible are hypoplastic. Dental abnormalities are common. We report a case with the typical clinical and radiological characteristics of the Pycnodysostosis associated with a conductive hearing loss, an association rarely reported. Case Presentation: A 12-year-female was admitted in our institute for short stature with a dysmorphic facies for evaluation. The patient reported a history of multiple fractures of the long bones after a trivial fall. On physical examination, she had the following features: short stature, limited mouth opening, short hands and feet with dysplastic nails; frontal and occipital bossing; and hypoplasia of the maxilla and mandible. Examination of the mouth: grooved palate, caries of the teeth, impacted and malposed teeth, persistent deciduous teeth and missing teeth. Laboratory investigations were normal. The radiographic examination showed a generalized increase in the bone density, slight condensation of the skull base and a very open mandibular angle. X-rays showed tapered phalanges with acro-osteolysis of the distal phalanges. A symptomatic treatment was proposed based on fracture prevention, oral hygiene, frequent dental visits and psychiatric support. Conclusion: The clinical and radiological features are the bases for the diagnosis of this disease. It is important to make the diagnosis as early as possible in order to plan the treatment and to provide a better life quality to the patients. PMID:27703936

Congenital axis dysmorphism in a medieval skeleton : …secunda a vertendo epistropheus….

2013-05-01

We describe here the axis dysmorphism that we observed in the skeletal remains of a human child dug up from a fifteenth century cemetery located in north-eastern Italy. This bone defect is discussed in the light of pertinent literature. We performed macroscopical examination and CT scan analysis of the axis. Axis structure was remarkably asymmetric. Whilst the left half exhibited normal morphology, the right one was smaller than normal, and its lateral articular surface showed horizontal orientation. In addition, the odontoid process appeared leftward deviated and displayed a supplementary articular-like facet situated on the right side of its surface. These findings suggest a diagnosis of unilateral irregular segmentation of atlas and axis, a rare dysmorphism dependent upon disturbances of notochordal development in early embryonic life. Likewise other malformations of the craniovertebral junction, this axis defect may alter the delicate mechanisms of upper neck movements and cause a complex series of clinical symptoms. This is an emblematic case whereby human skeletal remains may provide valuable information on the anatomical defects of craniovertebral junction.

The 6p25 deletion syndrome is a rare disorder characterized by Dandy-Walker malformation, congenital heart defects, developmental delay, dysmorphic facial features, and malformations of the anterior segment of the eye with a risk for glaucoma. Here we report a child harboring a cryptic de novo 6p25 deletion, bilateral optic disc coloboma and characteristic anterior segment anomalies. We review reported ophthalmic findings in patients with this syndrome. Retrospective case review of a 4-day-old male with Dandy-Walker malformation and cardiac defects who was referred with a suspected diagnosis of iris coloboma. The ophthalmic examination showed bilateral corectopia associated with posterior embryotoxon. Fundus examination revealed bilateral optic disc excavation, which was diagnosed as colobomatous because of its configuration and stability over time. Because of the association of posterior embryotoxon with Dandy-Walker malformation, a terminal 6p deletion syndrome was clinically suspected. Array comparative genomic hybridization (CGH) and fluorescence in situ hybridization (FISH) studies revealed a 3.2 Mb deletion at 6p25.2p25.3 including the FOXC1 gene. Neither unaffected parent carried this deletion. Optic disc colobomas may be found in patients carrying a 6p25 deletion. This has the potential to confound assessment of affected children for glaucoma and intracranial hypertension.

This submission presents a case of scoliosis in a patient with established Dandy-Walker anomaly of the brain. A retrospective review of the patient’s case notes was undertaken and the limited literature on this subject reviewed. The 13-year-old girl presented with a stiff right thoracic scoliosis typical of adolescent idiopathic scoliosis. The scoliotic segment also presented with significant lordosis. She had facial and truncal dysmorphism characteristic of Dandy-Walker complex and her brain images confirmed the diagnosis. She underwent scoliosis surgery by the posterior approach uneventfully. In conclusion scoliosis is hitherto unreported in the Dandy-Walker complex. The results of intervention appear satisfactory. PMID:29354751

Macrocephaly, which is defined as a head circumference greater than or equal to + 2 standard deviations, is a feature commonly observed in children with developmental delay and/or autism spectrum disorder. Although PTEN is a well-known gene identified in patients with this syndromic presentation, other genes in the PI3K-AKT-mTOR signalling pathway have also recently been suggested to have important roles. The aim of this study is to characterise the mutation spectrum of this group of patients. We performed whole-exome sequencing of 21 patients with macrocephaly and developmental delay/autism spectrum disorder. Sources of genomic DNA included blood, buccal mucosa and saliva. Germline mutations were validated by Sanger sequencing, whereas somatic mutations were validated by droplet digital PCR. We identified ten pathogenic/likely pathogenic mutations in PTEN ( n  = 4), PIK3CA ( n  = 3), MTOR ( n  = 1) and PPP2R5D ( n  = 2) in ten patients. An additional PTEN mutation, which was classified as variant of unknown significance, was identified in a patient with a pathogenic PTEN mutation, making him harbour bi-allelic germline PTEN mutations. Two patients harboured somatic PIK3CA mutations, and the level of somatic mosaicism in blood DNA was low. Patients who tested positive for mutations in the PI3K-AKT-mTOR pathway had a lower developmental quotient than the rest of the cohort (DQ = 62.8 vs. 76.1, p = 0.021). Their dysmorphic features were non-specific, except for macrocephaly. Among the ten patients with identified mutations, brain magnetic resonance imaging was performed in nine, all of whom showed megalencephaly. We identified mutations in the PI3K-AKT-mTOR signalling pathway in nearly half of our patients with macrocephaly and developmental delay/autism spectrum disorder. These patients have subtle dysmorphic features and mild developmental issues. Clinically, patients with germline mutations are difficult to distinguish from patients with somatic mutations, and therefore, sequencing of buccal or saliva DNA is important to identify somatic mosaicism. Given the high diagnostic yield and the management implications, we suggest implementing comprehensive genetic testing in the PI3K-AKT-mTOR pathway in the clinical evaluation of patients with macrocephaly and developmental delay and/or autism spectrum disorder.

Body dysmorphic disorder: Latest neuroanatomical and neuropsychological findings.

PubMed

Tasios, K; Michopoulos, I

Body dysmorphic disorder (BDD) is characterized by a preoccupation with a perceived defect or flaw in physical appearance that is not observable or appears slight to others. It leads to severe distress and functional impairment. Cognitive-behavioural and neurobiological similarities to obsessive compulsive disorder (OCD) have led to its newly conceived classification as an obsessive compulsive related disorder (OCRD). In the process of investigating the neurobiology of BDD, neuroimaging and neuropsychological studies have been conducted. This review presents the most recent research findings and their connection with BDD clinical features. Imaging studies have shown increased total white matter volume and caudate volume asymmetry in BDD patients. These findings are consistent with the striatal topography model of OCRDs. Other studies have showed perfusion deficits in bilateral anterior-medial temporal and occipital regions and asymmetric perfusion in parietal lobes. In addition, correlation between symptom severity and left inferior frontal gyrus volume reflects the degree of detailed, analytic encoding that occurs on day-to-day basis when viewing others and themselves, and that likely underlies their symptoms. Finally, positive correlation between right amygdala volume and symptom severity signifies pathological fear circuitry engagement, hypervigilance and heightened sensitivity to social situations. Neuropsychological studies of BDD reveal deficits in strategic organization, learning and free recall after short and long delays. Executive function deficits are related to spatial working memory and subsequent thinking speed as well as impaired higher level planning ability. BDD patients' organizational strategies tend to focus on detail rather than on larger, global clustering features. They are characterized by abnormal visual processing of both details and global elements, inaccurate processing of global elements and reduced flexibility in switching visual attention between global and local features. Moreover, BDD patients seem to have deficits in identifying facial emotional expressions and they tend to misinterpret expressions of disgust (and others) as anger. Poor insight and ideas of reference, common in BDD, might be related to emotion recognition biases for angry expressions. These findings have been supplemented by combined neuroimaging and neuropsychological studies. Left hemisphere hyperactivity for low and normal spatial frequency face tasks and abnormal activation of the amygdala for high and low spatial frequency face tasks suggests detail encoding and analysis in BDD. Patients may primarily perceive details but they are impaired in their ability to contextualize them holistically.

The New Face of Genetics: Creating A Multimedia Educational Tool for the Twenty-First Century

NASA Astrophysics Data System (ADS)

Fan, Audrey

In the study of certain genetic conditions, it is important to understand the specific "dysmorphology" associated with them. This describes the unique anatomical manifestations of the genetic condition. Traditionally, students learn about dysmorphology by reading text descriptions or looking at photographs of affected individuals. The New Face of Genetics is a film project that aims to teach students dysmorphology by featuring people who have specific genetic conditions. The goal is to enhance students' understanding of these conditions as well as to impart the humanity and beauty of the people who appear in the film. Students will have the opportunity to see dysmorphic features on the animated human form as well as meet individuals who are living with genetic difference. The target audience includes genetic counseling students and other medical professionals. Three short films were made in this format to demonstrate how this type of educational tool can be made. The featured conditions were Marfan syndrome, Sturge-Weber syndrome and Joubert syndrome. Future work will be carried out by other genetic counseling students who will make additional films based on our templates. A compendium of approximately 20 films will be eventually completed and released to genetic counseling programs and medical schools.

Larger imbalances on chromosome 4p in the form of deletions associated with Wolf-Hirschhorn syndrome (WHS) and duplications of chromosome 4p have a defined clinical phenotype. The critical region for both these clinical disorders has been narrowed based on the genotype-phenotype correlations. However, cryptic rearrangements in this region have been reported infrequently. We report on a male patient with a microduplication of chromosome 4p, who presents with findings of macrocephaly, irregular iris pigmentation-heterochromia, and preserved linear growth in addition to overlapping features of trisomy 4p such as seizures, delayed psychomotor development, and dysmorphic features including prominent glabella, low-set ears, and short neck. Using a high-density oligonucleotide microarray, we have identified a novel submicroscopic duplication involving dosage sensitive genes TACC3, FGFR3, and LETM1. The microduplication did not involve WHSC1 and WHSC2 which are considered in the critical region for WHS and trisomy 4p. This patient's presentation and genomic findings help further delineate clinical significance of re-arrangements in the 4p16 region without the involvement of WHS critical region.

We describe a pedigree presenting X-linked severe mental retardation associated with multiple congenital abnormalities and 46,XY gonadal dysgenesis, leading in one family member to female gender assignment. Female carriers are unaffected. The dysmorphic features are similar to those described in the {alpha}-thalassemia and mental retardation (ATR-X) syndrome, although there is no clinical evidence of {alpha}-thalassemia in this family. In addition, the family had other clinical features not previously observed in the ATR-X syndrome, including partial optic-nerve atrophy and partial ocular albinism. Mutations in a putative DNA helicase, termed XH2, have been reported to give rise to the ATR-X syndrome. Wemore » screened the YCH2 gene for mutations in affected members of the family and identified a 4-bp deletion at an intron/exon boundary that removes an invariant 3{prime} splice-acceptor site. The mutation cosegregates with the syndrome. The genomic deletion causes missplicing of the pre-mRNA, which results in the loss of 8 bp of coding sequence, thereby generating a frameshift and a downstream premature stop codon. Our finding increases the range of clinical features associated with mutations in the XH2 gene. 17 refs., 4 figs., 2 tabs.« less

Rubinstein-Taybi syndrome (RTS, OMIM 180849) and Filippi syndrome (FLPIS, OMIM 272440) are both rare syndromes, with multiple congenital anomalies and intellectual deficit (MCA/ID). We present a patient with intellectual deficit, short stature, bilateral syndactyly of hands and feet, broad thumbs, ocular abnormalities, and dysmorphic facial features. These clinical features suggest both RTS and FLPIS. Initial DNA analysis of DNA isolated from blood did not identify variants to confirm either of these syndrome diagnoses. Whole-exome sequencing identified a homozygous variant in C9orf173, which was novel at the time of analysis. Further Sanger sequencing analysis of FLPIS cases tested negative for CKAP2L variants did not, however, reveal any further variants. Subsequent analysis using DNA isolated from buccal mucosa revealed a mosaic variant in CREBBP. This report highlights the importance of excluding mosaic variants in patients with a strong but atypical clinical presentation of a MCA/ID syndrome if no disease-causing variants can be detected in DNA isolated from blood samples. As the striking syndactyly observed in the present case is typical for FLPIS, we suggest CREBBP analysis in saliva samples for FLPIS syndrome cases in which no causal CKAP2L variant is detected.

Body dysmorphic disorder causes significant suffering and serious impairment in psychosocial functions. However, this disease with dangerous risks is scarcely mentioned in the Hungarian medical literature. The objective of the author is to give a detailed review about this almost unknown, but relatively common disorder. The serious disorder of body perception is in the centre of symptoms, leading to social isolation, anxiety, depression and obsessive-compulsive phenomena. The disorder often remains unrecognized because of the lack of insight of disease. Comorbidity with affective disorders, anxiety disorders, personality disorders, eating disorders, alcoholism and substance use disorders is common. The life quality of affected patients is bad, the risk of suicide or violence is high. Biological, psychological and sociocultural factors play an important role in the etiopathogenesis of the disorder. Imaging techniques and neuropsychological measures revealed changes characteristic for the disease. Childhood abuse and neglect, appearance-related critical remarks, stressors and the impact of media are also supposed to have role in the development of the disorder. The point prevalence is 0.7-2.5% in the general population, however, in special groups such as in tertiary students, psychiatric, dermatological and cosmetic surgery patients the prevalence rates may be much higher. Typically, the disease begins in early adolescence, and it persists and deteriorates without treatment, showing a chronic course. By means of pharmacotherapy and/or psychotherapy long-during improvement or full recovery can be achieved within a relatively short period of time.

Congenital cataract, facial dysmorphism and demyelinating neuropathy (CCFDN) in 10 Czech gypsy children – frequent and underestimated cause of disability among Czech gypsies

PubMed Central

2014-01-01

Background Congenital Cataract Facial Dysmorphism and demyelinating Neuropathy (CCFDN, OMIM 604468) is an autosomal recessive multi-system disorder which was first described in Bulgarian Gypsies in 1999. It is caused by the homozygous founder mutation c.863 + 389C > T in the CTDP1 gene. The syndrome has been described exclusively in patients of Gypsy ancestry. The prevalence of this disorder in the Gypsy population in the Czech Republic and Central Europe is not known and is probably underestimated and under-diagnosed. Methods We clinically diagnosed and assessed 10 CCFDN children living in the Czech Republic. All patients are children of different ages, all of Gypsy origin born in the Czech Republic. Molecular genetic testing for the founder CTDP1 gene mutation was performed. Results All patients are homozygous for the c.863 + 389C > T mutation in the CTDP1 gene. All patients presented a bilateral congenital cataract and microphthalmos and had early cataract surgery. Correct diagnosis was not made until the age of two. All patients had variably delayed motor milestones. Gait is characteristically paleocerebellar in all the patients. Mental retardation was variable and usually mild. Conclusions Clinical diagnosis of CCFDN should be easy for an informed pediatrician or neurologist by the obligate signalling trias of congenital bilateral cataract, developmental delay and later demyelinating neuropathy. Our data indicate a probably high prevalence of CCFDN in the Czech Gypsy ethnic subpopulation. PMID:24690360

Facial cosmetic surgery is becoming more popular. Patients generally indicate they are satisfied with the results. Certain patient characteristics, however, have been described as negative predictors for satisfaction. Psychopathology such as body dysmorphic disorder and personality disorders are notorious. Psychosocial and cultural factors are more difficult to distinguish. This systematic review defines the predictors, other than body dysmorphic disorder, of an unsatisfactory outcome after facial cosmetic surgery. The authors are also interested in whether valid preoperative assessment instruments are available to determine these factors. An extensive systematic PubMed/MEDLINE and Cochrane Library search was performed. In addition, relevant studies from the reference lists of the selected articles were added. There were no publication-year restrictions, and the last search was conducted on July 20, 2014. All factors described as negative predictors for patient satisfaction after facial cosmetic surgery were identified. Twenty-seven articles were analyzed, including 11 prospective studies, two retrospective studies, one case study, eight reviews, and five expert opinions. The following factors were identified: male sex, young age, unrealistic expectations, minimal deformities, demanding patients, "surgiholics," relational or familial disturbances, an obsessive personality, and a narcissistic personality. This review indicates the possible demographic and psychosocial predictors for an unsatisfactory outcome of facial cosmetic surgery. A brief personality assessment tool that could be used to address predictors preoperatively was not found. The authors suggest use of the Glasgow Benefit Inventory to assess patient satisfaction postoperatively. Further research is being undertaken to develop such an instrument.

Background With the advent of the fifth edition of Diagnostic and Statistical Manual of Mental Disorders, body dysmorphic disorder (BDD) has been subsumed into the obsessive-compulsive disorders and related disorders (OCDRD) category. Objective We aimed to determine the empirical evidence regarding the potential relationship between BDD and obsessive-compulsive disorder (OCD) based on the prevalence data, etiopathogenic pathways, and clinical characterization of patients with both disorders. Method A comprehensive search of databases (PubMed and PsycINFO) was performed. Published manuscripts between 1985 and May 2015 were identified. Overall, 53 studies fulfilled inclusion criteria. Results Lifetime comorbidity rates of BDD–OCD are almost three times higher in samples with a primary diagnosis of BDD than those with primary OCD (27.5% vs 10.4%). However, other mental disorders, such as social phobia or major mood depression, are more likely among both types of psychiatric samples. Empirical evidence regarding the etiopathogenic pathways for BDD–OCD comorbidity is still inconclusive, whether concerning common shared features or one disorder as a risk factor for the other. Specifically, current findings concerning third variables show more divergences than similarities when comparing both disorders. Preliminary data on the clinical characterization of the patients with BDD and OCD indicate that the deleterious clinical impact of BDD in OCD patients is greater than vice versa. Conclusion Despite the recent inclusion of BDD within the OCDRD, data from comparative studies between BDD and OCD need further evidence for supporting this nosological approach. To better define this issue, comparative studies between BDD, OCD, and social phobia should be carried out. PMID:26345330

Body dysmorphic disorder (BDD) was categorised in DSM-5 within the newly created 'obsessive-compulsive and related disorders' chapter, however this classification remains subject to debate. Confirmatory factor analysis was used to test competing models of the co-occurrence of symptoms of BDD, obsessive-compulsive disorder, unipolar depression, anxiety, and eating disorders in a community sample of adolescents, and to explore potential sex differences in these models. Self-report questionnaires assessing disorder symptoms were completed by 3149 Australian adolescents. The fit of correlated factor models was calculated separately in males and females, and measurement invariance testing compared parameters of the best-fitting model between males and females. All theoretical models of the classification of BDD had poor fit to the data. Good fit was found for a novel model where BDD symptoms formed a distinct latent factor, correlated with affective disorder and eating disorder latent factors. Metric non-invariance was found between males and females, and the majority of factor loadings differed between males and females. Correlations between some latent factors also differed by sex. Only cross-sectional data were collected, and the study did not assess a broad range of DSM-5 defined eating disorder symptoms or other disorders in the DSM-5 obsessive-compulsive and related disorders chapter. This study is the first to statistically evaluate competing models of BDD classification. The findings highlight the unique features of BDD and its associations with affective and eating disorders. Future studies examining the classification of BDD should consider developmental and sex differences in their models. Copyright © 2017. Published by Elsevier B.V.

Background Body dysmorphic disorder (BDD) is a common and often severe disorder. Clinical observations suggest that panic attacks triggered by BDD symptoms may be common. However, to our knowledge, no study has examined such panic attacks in BDD. We investigated the prevalence, clinical features, and correlates of BDD-triggered panic attacks in individuals with this disorder. Methods Panic attacks and other variables were assessed using reliable and valid measures in 76 individuals with lifetime DSM-IV BDD. Results 28.9% (95% CI, 18.5%–39.4%) of participants reported lifetime panic attacks triggered by BDD symptoms. The most common triggers of such attacks were feeling that others were looking at or scrutinizing the perceived appearance defects (61.9%), looking in the mirror at perceived defects (38.1%), and being in bright light where perceived defects would be more visible (23.8%). The most common panic attack symptoms were palpitations (86.4%), sweating (66.7%), shortness of breath (63.6%), trembling or shaking (63.6%), and fear of losing control or going crazy (63.6%). Compared to participants without such panic attacks, those with BDD-triggered panic attacks had more severe lifetime BDD, social anxiety, and depressive symptoms, as well as poorer functioning and quality of life on a number of measures. They were also less likely to be employed and more likely to have been psychiatrically hospitalized and to have had suicidal ideation due to BDD. Conclusions Panic attacks triggered by BDD-related situations appear common in individuals with this disorder. BDD-triggered panic attacks were associated with greater symptom severity and morbidity.

Body dysmorphic disorder (BDD) usually begins during adolescence but little is known about the prevalence, etiology, and patterns of comorbidity in this age group. We investigated the prevalence of BDD symptoms in adolescents and young adults. We also report on the relative importance of genetic and environmental influences on BDD symptoms, and the risk for co-existing psychopathology. Prevalence of BDD symptoms was determined by a validated cut-off on the Dysmorphic Concerns Questionnaire (DCQ) in three population-based twin cohorts at ages 15 (n = 6968), 18 (n = 3738), and 20-28 (n = 4671). Heritability analysis was performed using univariate model-fitting for the DCQ. The risk for co-existing psychopathology was expressed as odds ratios (OR). The prevalence of clinically significant BDD symptoms was estimated to be between 1 and 2% in the different cohorts, with a significantly higher prevalence in females (1.3-3.3%) than in males (0.2-0.6%). The heritability of body dysmorphic concerns was estimated to be 49% (95% CI 38-54%) at age 15, 39% (95% CI 30-46) at age 18, and 37% (95% CI 29-42) at ages 20-28, with the remaining variance being due to non-shared environment. ORs for co-existing neuropsychiatric and alcohol-related problems ranged from 2.3 to 13.2. Clinically significant BDD symptoms are relatively common in adolescence and young adulthood, particularly in females. The low occurrence of BDD symptoms in adolescent boys may indicate sex differences in age of onset and/or etiological mechanisms. BDD symptoms are moderately heritable in young people and associated with an increased risk for co-existing neuropsychiatric and alcohol-related problems.

We report the case of a 34-year-old female resulting from a father-daughter sexual abuse and presenting a phenotype of mild intellectual disability with minor dysmorphic features. Karyotyping showed a normal 46, XX constitution. Array-based comparative genomic hybridization (array-CGH) revealed a heterozygote 320kb 6p22.3 microdeletion in the proband, encompassing only one known gene, and therefore unlikely to be the cause of the phenotype. However, the role of other genetic factors, such as a recessive condition, could not be ruled out as a putative cause for the phenotype. On the other hand, the role played by a heavily detrimental familial situation on the development and outcome, and possibly leading or contributing to a mild intellectual disability, should be taken into account.

Microcephalic osteodysplastic primordial dwarfism type I (MOPD I) is a rare autosomal recessive developmental disorder characterized by extreme intrauterine growth retardation, severe microcephaly, central nervous system abnormalities, dysmorphic facial features, skin abnormalities, skeletal changes, limb deformations, and early death. Recently, mutations in the RNU4ATAC gene, which encodes U4atac, a small nuclear RNA that is a crucial component of the minor spliceosome, were found to cause MOPD I. MOPD I is the first disease known to be associated with a defect in small nuclear RNAs. We describe here the clinical and molecular data for 17 cases of MOPD I, including 15 previously unreported cases, all carrying biallelic mutations in the RNU4ATAC gene. © 2011 John Wiley & Sons A/S.

A 4 year 3 month old boy with insulin dependent diabetes mellitus (IDDM), autoimmune thyroiditis, slight mental retardation, facial dysmorphism, and a de novo ring chromosome 18 (deletion 18q22.3-18qter) is described. This unique association of defects could represent a chance association. Alternatively, the clinical features could be the result of the chromosomal aberration. If so, one could speculate that a gene or genes on chromosome 18 might act as a suppressor or activator of the autoimmune process by itself or in concert with other IDDM loci.

Hypotonia-cystinuria syndrome is a very rare autosomal recessive contiguous gene deletion syndrome of PREPL and SLC3A1 at 2p21 with neuromuscular and neuroendocrinologic presentation. We report a two-year-six-month-old affected female infant and her five-month-old affected brother with a novel homozygous deletion in SLC3A1 and PREPL gene. Both of siblings had mild facial dysmorphism, hypotonia, feeding problems, failure to thrive, developmental delay. She also had dilated cardiomyopathy which differ from other reported patients. Therefore cardiomyopathy may also be considered one of the features of hypotonia-cystinuria syndrome. With this case report, we present cardiac manifestation of hypotonia-cystinuria syndrome for the first time. Because of two siblings had hyperechogenic bowel in prenatal sonography, it might be a prenatal marker for HCS.

The present study aims to examine the correlation of body dysmorphic disorder, with metacognitive subscales, metaworry and thought-fusion. The study was conducted in a correlation framework. Sample included 155 high school students in Isfahan, Iran in 2013-2014, gathered through convenience sampling. To gather data about BDD, Yale-Brown Obsessive Compulsive Scale Modified for BDD was applied. Then, Meta Cognitive Questionnaire, Metaworry Questionnaire, and Thought-Fusion Inventory were used to assess metacognitive subscales, metaworry and thought-fusion. Data obtained from this study were analyzed using Pearson correlation and multiple regressions in SPSS 18. Result indicated YBOCS-BDD scores had a significant correlation with scores from MCQ (P<0.05), MWG (P<0.05), and TFI (P<0.05). Also, multiple regressions were run to predict YBOCS from TFI, MWQ, and MCQ-30. These variables significantly predicted YBOCS [F (3,151) =32.393, R2=0.57]. Findings indicated that body dysmorphic disorder was significantly related to metacognitive subscales, metaworry, and thought fusion in high school students in Isfahan, which is in line with previous studies. A deeper understanding of these processes can broaden theory and treatment of BDD, thereby improve the lives of sufferers and potentially protect others from developing this devastating disorder.

Deletions encompassing TAK1-binding protein 2 (TAB2) associated with isolated and syndromic congenital heart defects. Rare missense variants are found in patients with a similar phenotype as well as in a single individual with frontometaphyseal dysplasia. We describe a family and an additional sporadic patient with polyvalvular heart disease, generalized joint hypermobility and related musculoskeletal complications, soft, velvety and hyperextensible skin, short limbs, hearing impairment, and facial dysmorphism. In the first family, whole-exome sequencing (WES) disclosed the novel TAB2 c.1398dup (p.Thr467Tyrfs*6) variant that eliminates the C-terminal zinc finger domain essential for activation of TAK1 (TGFβ-activated kinase 1)-dependent signaling pathways. The sporadic case carryed a ~2 Mb de novo deletion including 28 genes also comprising TAB2. This study reveal an association between TAB2 mutations and a phenotype resembling Ehlers-Danlos syndrome with severe polyvalvular heart disease and subtle facial dysmorphism. Our findings support the existence of a wider spectrum of clinical phenotypes associated with TAB2 perturbations and emphasize the role of TAK1 signaling network in human development. © 2017 John Wiley & Sons A/S.

While there are several reports of trisomy 10q (at least 35), we are not aware of previous cases of 10q tetrasomy. We present what we believe to be the initial report of such a case. R.J. is a 6 1/2 year old white male who presented with multiple dysmorphic features, marked articulation problems, hyperactivity, and developmental delays. He is the product of a term uncomplicated pregnancy. There was a normal spontaneous vaginal delivery with a birth weight of 6 lbs. 4oz. and length was 19 1/2 inch. Dysmorphic features include small size, an asymmetrically small head, low set ears withmore » overfolded helixes, bilateral ptosis, downslanting eyes, right eye esotropia, prominent nose, asymmetric facies, high palate, mild pectus excavatum deformity of chest, and hyperextensible elbow joints. The patient is in special needs classes for mildly mentally handicapped students. Chromosome analysis at a resolution of 800 bands revealed a complex rearrangement of chromosomes 10 and 11. The segment 10q25.3 to q16.3 appears to be inverted and duplicated within the long arm of chromosome 10 at band q25.3 and the same segment of chromosome 10 is present on the terminal end of the short arm of chromosome 11. There is no visible loss of material from chromosome 11. Fluorescence in situ hybridization was performed with a chromosome 10 specific {open_quotes}paint{close_quotes} to confirm that all of the material on the abnormal 10 and the material on the terminal short arm of 11 was from chromosome 10. Thus, it appears that the segment 10q25.3 to q26.3 is present in four copies. Parental chromosome studies are normal. We compared findings which differ in that the case of 10q tetrasomy did not have prenatal growth deficiency, microphthalmia, cleft palate, digital anomalies, heart, or renal defects. Whereas most cases of 10q trisomy are said to have severe mental deficiency, our case of 10q tetrasomy was only mildly delayed. We report this first apparent cited case of 10q tetrasomy.« less

Cornelia de Lange syndrome (CdLS) is a both clinically and genetically heterogeneous syndrome. In its classical form, it is characterised by distinctive facial features, intra-uterine growth retardation, short stature, developmental delay, and anomalies in multiple organ systems. NIPBL, SMC1A, SMC3, RAD21 and HDAC8, all involved in the cohesin pathway, have been identified to cause CdLS. Growth hormone (GH) secretion has been reported as normal, and to our knowledge, there are no reports on the effect of recombinant human GH treatment in CdLS patients. We present a patient born small for gestational age with persistent severe growth retardation [height -3.4 standard deviation score (SDS)] and mild dysmorphic features, who was treated with GH from 4.3 years of age onward and was diagnosed 6 years later with CdLS using whole-exome sequencing. Treatment led to a height gain of 1.6 SDS over 8 years. Treatment was interrupted shortly due to high serum insulin-like growth factor-1 serum values. In conclusion, GH therapy may be effective and safe for short children with CdLS.

Nance-Horan syndrome (NHS) is an X-linked disorder characterized by congenital cataracts, dental anomalies, dysmorphic features, and, in some cases, mental retardation. NHS has been mapped to a 1.3-Mb interval on Xp22.13. We have confirmed the same localization in the original, extended Australian family with NHS and have identified protein-truncating mutations in a novel gene, which we have called "NHS," in five families. The NHS gene encompasses approximately 650 kb of genomic DNA, coding for a 1,630-amino acid putative nuclear protein. NHS orthologs were found in other vertebrates, but no sequence similarity to known genes was identified. The murine developmental expression profile of the NHS gene was studied using in situ hybridization and a mouse line containing a lacZ reporter-gene insertion in the Nhs locus. We found a complex pattern of temporally and spatially regulated expression, which, together with the pleiotropic features of NHS, suggests that this gene has key functions in the regulation of eye, tooth, brain, and craniofacial development.

Here we report a patient with 11p15.4p15.5 duplication and 13q34 deletion presenting with Beckwith-Wiedemann syndrome (BWS) and moderate deficiency of factor VII (FVII). The duplication was initially diagnosed on methylation-sensitive multiplex ligation-dependent probe amplification. Array comparative genome hybridization confirmed its presence and indicated a 13q34 distal deletion. The patient's clinical symptoms, including developmental delay and facial dysmorphism, were typical of BWS with paternal 11p15 trisomy. Partial 13q monosomy in this patient is associated with moderate deficiency of FVII and may also overlap with a few symptoms of paternal 11p15 trisomy such as developmental delay and some facial features. To our knowledge this is the first report of 11p15.4p15.5 duplication associated with deletion of 13q34 and FVII deficiency. Moreover, this report emphasizes the importance of detailed clinical as well as molecular examinations in patients with BWS features and developmental delay. © 2015 Japan Pediatric Society.

Chromosome 7q36 microdeletion syndrome is a rare genomic disorder characterized by underdevelopment of the brain, microcephaly, anomalies of the sex organs, and language problems. Developmental delay, intellectual disability, autistic spectrum disorders, BDMR syndrome, and unusual facial morphology are the key features of the chromosome 2q37 microdeletion syndrome. A genetic screening for two brothers with global developmental delay using high-resolution chromosomal analysis and subtelomeric multiplex ligation-dependent probe amplification revealed subtelomeric rearrangements on the same sites of 2q37.2 and 7q35, with reversed deletion and duplication. Both of them showed dysmorphic facial features, severe disability of physical and intellectual development, and abnormal genitalia with differential abnormalities in their phenotypes. The family did not have abnormal genetic phenotypes. According to the genetic analysis of their parents, adjacent-1 segregation from their mother's was suggested as a mechanism of their gene mutation. By comparing the phenotypes of our patients with previous reports on similar patients, we tried to obtain the information of related genes and their chromosomal locations. © 2013.

Chromosome 10q deletions are rare and phenotypically diverse. Such deletions differ in length and occur in numerous regions on the long arm of chromosome 10, accounting for the wide clinical variability. Commonly reported findings include dysmorphic facial features, microcephaly, developmental delay, and genitourinary abnormalities. Here, we report on a female patient with a novel interstitial 5.54 Mb deletion at 10q24.31-q25.1. This patient had findings in common with a previously reported patient with an overlapping deletion, including renal anomalies and an orofacial cleft, but also demonstrated lobar holoprosencephaly and a Dandy-Walker malformation, features which have not been previously reported with 10q deletions. An analysis of the region deleted in our patient showed numerous genes, such as KAZALD1, PAX2, SEMA4G, ACTRA1, INA, and FGF8, whose putative functions may have played a role in the phenotype seen in our patient. © 2014 Wiley Periodicals, Inc.

Proximal 4p deletion syndrome is a relatively rare genetic condition characterized by dysmorphic facial features, limb anomalies, minor congenital heart defects, hypogonadism, cafe-au-lait spots, developmental delay, tall and thin habitus, and intellectual disability. At present, over 20 cases of this syndrome have been published. However, duplication of the same region in proximal 4p has never been reported. Here, we describe a 2-year-5-month-old boy with severe congenital heart defects, limb anomalies, hypogonadism, distinctive facial features, pre- and postnatal developmental delay, and mild cognitive impairments. A de novo 4.5-Mb interstitial duplication at 4p15.2p15.1 was detected by chromosomal microarray analysis. Next-generation sequencing was employed and confirmed the duplication, but revealed no additional pathogenic variants. Several candidate genes in this interval responsible for the complex clinical phenotype were identified, such as RBPJ, STIM2, CCKAR, and LGI2. The results suggest a novel contiguous gene duplication syndrome. © 2016 S. Karger AG, Basel.

Several Wolf-Hirschhorn syndrome patients have been studied, mouse models for a few candidate genes have been constructed and two WHS critical regions have been postulated, but the molecular basis of the syndrome remains poorly understood. Single gene contributions to phenotypes of microdeletion syndromes have often been based on the study of patients carrying small, atypical deletions. We report a 5-year-old girl harboring an atypical 1.5Mb del4p16.3 and review seven previously published patients carrying a similar deletion. They show a variable clinical presentation and the only consistent feature is post-natal growth delay. However, four of eight patients carry a ring (4), and ring chromosomes in general are associated with growth deficiency. The Greek helmet profile is absent, although a trend towards common dysmorphic features exists. Variable expressivity and incomplete penetrance might play a role in WHS, resulting in difficult clinical diagnosis and challenge in understanding of the genotype/phenotype correlation.

Delusional versus nondelusional body dysmorphic disorder: recommendations for DSM-5

Phillips, Katharine A.; Hart, Ashley S.; Simpson, Helen Blair; Stein, Dan J.

2016-01-01

The core feature of body dysmorphic disorder (BDD) is distressing or impairing preoccupation with nonexistent or slight defects in one’s physical appearance. BDD beliefs are characterized by varying degrees of insight, ranging from good (ie, recognition that one’s BDD beliefs are not true) through “absent insight/delusional” beliefs (ie, complete conviction that one’s BDD beliefs are true). The Diagnostic and Statistical Manual of Mental Disorders, 3rd ed., rev. (DSM-III-R) and The Diagnostic and Statistical Manual of Mental Disorders, 4th ed. (DSM-IV) classified BDD’s nondelusional form in the somatoform section of the manual and its delusional form in the psychosis section, as a type of delusional disorder, somatic type (although DSM-IV allowed double-coding of delusional BDD as both a psychotic disorder and BDD). However, little or no evidence on this issue was available when these editions were published. In this article, we review the classification of BDD’s delusional and nondelusional variants in earlier editions of DSM and the limitations of their approaches. We then review empirical evidence on this topic, which has become available since DSM-IV was developed. Available evidence indicates that across a range of validators, BDD’s delusional and nondelusional variants have many more similarities than differences, including response to pharmacotherapy. Based on these data, we propose that BDD’s delusional and nondelusional forms be classified as the same disorder and that BDD’s diagnostic criteria include an insight specifier that spans a range of insight, including absent insight/delusional BDD beliefs. We hope that this recommendation will improve care for patients with this common and often-severe disorder. This increased understanding of BDD may also have implications for other disorders that have an “absent insight/delusional” form. PMID:23659348

Obese patients, mainly females, feel uncomfortable and unsatisfied with their physical appearance; they have a wrong perception of their image and consequently diminish their self-esteem, sometimes showing difficulties in functional areas such as work, relationship, social activity. Beside health concerns, improving their appearance and body image are often common motives for weight loss in obese individuals and after weight loss about 30% of bariatric surgery patients undergo plastic surgical correction of excessive skin. The authors investigated psychological and psychiatric traits in post-bariatric patients undergoing body-contouring surgery to underline the strong correlation between psychiatry and obesity and avoid unsatisfactory results in post-bariatric patients. The Mini International Neuropsychiatric Interview, Beck Depression Inventory II, Yale-Brown Obsessive Compulsive Scale modified for Body Dysmorphic Disorder Tridimensional Personality Questionnaire, Body Uneasiness Test, Barratt Impulsiveness Scale 11, and Binge Eating Scale were performed in 36 post-bariatric patients looking for plastic surgery and 21 controls, similar for clinical features, not seeking shape remodelling. Much different psychiatric pathology characterizes cases, including current body dysmorphic disorder and previous major depression and anxiety disorders, impulsivity, binging and body uneasiness are other common traits. In post-obesity rehabilitation, a strong collaboration between the plastic surgeon and psychiatrist is recommended to reduce the number of non-compliant patients. Preoperative psychological assessment of the body-contouring patient should be a central part of the initial plastic surgery consultation, as it should be for all plastic surgery patients.

The prevalence of autism spectrum disorders (ASD) and the number of identified ASD-related genes have increased in recent years. The SETD5 gene encodes a SET-containing-domain 5 protein, a likely reader enzyme. Genetic evidences suggest that SETD5 malfunction contributes to ASD phenotype, such as on intellectual disability (ID) and facial dysmorphism. In this review, we mapped the clinical phenotypes of individuals carrying mutations on the SETD5 gene that are associated with ASD and other chromatinopathies (mutation in epigenetic modifiers that leads to the development of neurodevelopmental disorders such as ASD). After a detailed systematic literature review and analysis of public disease-related databank, we found so far 42 individuals carrying mutations on the SETD5 gene, with 23.8% presenting autistic-like features. Furthermore, most of mutations occurred between positions 9,480,000-9,500,000 bp on chromosome 3 (3p25.3) at the SETD5 gene locus. In all males, mutations in SETD5 presented high penetrance, while in females the clinical phenotype seems more variable with two reported cases showing normal female carriers and not presenting ASD or any ID-like symptoms. At the molecular level, SETD5 interacts with proteins of PAF1C and N-CoR complexes, leading to a possible involvement with chromatin modification pathway, which plays important roles for brain development. Together, we propose that mutations on the SETD5 gene could lead to a new syndromic condition in males, which is linked to 3p25 syndrome, and can leads to ASD-related intellectual disability and facial dysmorphism. © 2018 Wiley Periodicals, Inc.

More and more people worldwide and also in Germany are using botulinum toxin type A (BoNT-A) and hyaluronic acid injections for skin rejuvenation. Study on body image and self-esteem of women with BoNT-A and/or hyaluronic acid filler treatment. A total of 145 women who requested BoNT-A and/or hyaluronic acid injections completed a survey comprised of the body dysmorphic disorder questionnaire, the Rosenberg self-esteem scale and questionnaires on the attitudes and motives on measures for optimization of the body and demographic features. Using this instrument data on the body image and self-esteem as well as attitudes and motives for utilization of minimally invasive skin rejuvenation were collated. Female users of minimally invasive skin rejuvenation showed an overall higher socioeconomic status and an above average high monthly income. They lived in a partnership more often in comparison to women of equal age living in Berlin. The users of BoNT-A and/or hyaluronic acid fillers showed no conspicuous differences in body image and self-esteem. They showed a moderately positive attitude to body optimization procedures and 91% achieved their standard weight with a body mass index (BMI) of ≤25 kg/m 2 in comparison to 56% of German women in the same age range (25 to ≥75 years old). In the first study of body image and self-esteem in users of BoNT‑A and/or dermal fillers in German women, the users showed no signs of body dysmorphic patterns or disorders of self-esteem.

Background Body dysmorphic disorder (BDD) is a psychiatric disorder characterized by a preoccupation with an imagined or slight defect which causes significant distress or impairment in functioning. Few studies have assessed gender differences in BDD in a non clinical population. Also no study assessed BDD in medical students. This study was designed to determine the point prevalence of BDD in Pakistani medical students and the gender differences in prevalence of BDD, body foci of concern and symptoms of BDD. Methods The medical students enrolled in a medical university in Karachi, Pakistan filled out a self-report questionnaire which assessed clinical features of BDD. BDD was diagnosed according to the DSM-IV criteria. Results Out of the 156 students, 57.1% were female. A total of 78.8% of the students reported dissatisfaction with some aspect of their appearance and 5.8% met the DSM-IV criteria for BDD. The male to female ratio for BDD was 1.7. Regarding gender differences in body foci of concern, the top three reported foci of concern in male students were head hair (34.3%), being fat (32.8%), skin (14.9%) and nose(14.9%), whereas in females they were being fat (40.4%), skin (24.7%) and teeth (18%). Females were significantly more concerned about being fat (p = 0.005). Male students were significantly more concerned about being thin (p = 0.01) and about head hair (p = 0.012). Conclusion BDD is fairly common in our medical student population, with a higher prevalence in males. Important gender differences in BDD symptomatology and reported body foci of concern were identified which reflected the influence of media on body image perception. The impact of cultural factors on the prevalence as well as gender differences in BDD symptomatology was also established. PMID:18400091

Can understanding the neurobiology of body dysmorphic disorder (BDD) inform treatment?

We aim to provide a clinically focused review of the neurobiological literature in body dysmorphic disorder (BDD), with a focus on structural and functional neuroimaging. There has been a recent influx of studies examining the underlying neurobiology of BDD using structural and functional neuroimaging methods. Despite obvious symptom similarities with obsessive-compulsive disorder (OCD), no study to date has directly compared the two groups using neuroimaging techniques. Studies have established that there are limbic and visual cortex abnormalities in BDD, in contrast to fronto-striatal differences in OCD. Such data suggests affect or visual training maybe useful in BDD. © The Royal Australian and New Zealand College of Psychiatrists 2015.

Selfie use: The implications for psychopathology expression of body dysmorphic disorder

Preoccupation with a body part can lead to indulgence in various forms of coping behavior. Users are frequently using technology as well as selfie to overcome their anxiety to relate to a body part as well as get approval from other online users. The present case highlights the excessive use of selfie to manage the distress-related body dysmorphic disorder (BDD). Psychiatric interview and assessment tools were used to elicit information about BDD, technology use, and affective states. Repeated use of selfie has been thought to manage the distress associated with appearance. It implies the need for screening excessive use of technology as comorbid condition and psychoeducation for promotion of healthy use of technology. PMID:29456333

Body dysmorphic disorder (BDD) is a distressing and impairing preoccupation with a slight or imagined defect in appearance. There are few reports on the prevalence of BDD in the Turkish population. To investigate the frequency of BDD in dermatology settings, and to compare the results from cosmetic dermatology with those from general dermatology settings. This cross-sectional study recruited 400 patients from cosmetic dermatology (CD) (n = 200) and general dermatology (GD) clinics (n = 200). A mini-survey was used to collect demographic and clinical characteristics, and the dermatology version of a brief self-report BDD screening questionnaire was administered. A five-point Likert scale was used for objective scoring of the stated concern, which was performed by dermatologists, and patients who scored ≥ 3 were excluded from the study. In total, 318 patients (151 in the CD group and 167 in the GD group) completed the study, and of these, 20 were diagnosed with BDD. The CD group had a higher rate of BDD (8.6%) than the GD group (4.2%) but this was not significant (P = 0.082). The major concern focused on body and weight (40.0%), followed by acne (25.0%). The number of cosmetic procedures in dermatology practices is increasing Therefore, it is becoming more important to recognize patients with BDD. Although the rates of BDD found in the present study are in agreement with the literature data, population-based differences still exist between this study and previous studies. © 2014 British Association of Dermatologists.

Constitutional bone impairment in Noonan syndrome.

Noonan syndrome (NS) is an autosomal dominant trait characterized by genotypic and phenotypic variability. It belongs to the Ras/MAPK pathway disorders collectively named Rasopathies or neurocardiofaciocutaneous syndromes. Phenotype is characterized by short stature, congenital heart defects, facial dysmorphisms, skeletal and ectodermal anomalies, cryptorchidism, mild to moderate developmental delay/learning disability, and tumor predisposition. Short stature and skeletal dysmorphisms are almost constant and several studies hypothesized a role for the RAS pathway in regulating bone metabolism. In this study, we investigated the bone quality assessed by phalangeal quantitative ultrasound (QUS) and the metabolic bone profiling in a group of patients with NS, to determine whether low bone mineralization is primary or secondary to NS characteristics. Thirty-five patients were enrolled, including 20 males (55.6%) and 15 females (44.5%) aged 1.0-17.8 years (mean 6.4 ± 4.5, median 4.9 years). Each patients was submitted to clinical examination, estimation of the bone age, laboratory assays, and QUS assessment. Twenty-five percent of the cohort shows reduced QUS values for their age based on bone transmission time. Bone measurement were adjusted for multiple factors frequently observed in NS patients, such as growth retardation, delayed bone age, retarded puberty, and reduced body mass index, potentially affecting bone quality or its appraisal. In spite of the correction attempts, QUS measurement indicates that bone impairment persists in nearly 15% of the cohort studied. Our results indicate that bone impairment in NS is likely primary and not secondary to any of the phenotypic traits of NS, nor consistent with metabolic disturbances. © 2017 Wiley Periodicals, Inc. © 2017 Wiley Periodicals, Inc.

Congenital cardiac and neurodevelopmental deficits have been recently linked to the mediator complex subunit 13-like protein MED13L, a subunit of the CDK8-associated mediator complex that functions in transcriptional regulation through DNA-binding transcription factors and RNA polymerase II. Heterozygous MED13L variants cause transposition of the great arteries and intellectual disability (ID). Here, we report eight patients with predominantly novel MED13L variants who lack such complex congenital heart malformations. Rather, they depict a syndromic form of ID characterized by facial dysmorphism, ID, speech impairment, motor developmental delay with muscular hypotonia and behavioral difficulties. We thereby define a novel syndrome and significantly broaden the clinical spectrum associated with MED13L variants. A prominent feature of the MED13L neurocognitive presentation is profound language impairment, often in combination with articulatory deficits. PMID:25758992

Using whole-exome sequencing, we identified seven unrelated individuals with global developmental delay, hypotonia, dysmorphic facial features, and an increased frequency of short stature, ataxia, and autism with de novo heterozygous frameshift, nonsense, splice, and missense variants in the Early B-cell Transcription Factor Family Member 3 (EBF3) gene. EBF3 is a member of the collier/olfactory-1/early B-cell factor (COE) family of proteins, which are required for central nervous system (CNS) development. COE proteins are highly evolutionarily conserved and regulate neuronal specification, migration, axon guidance, and dendritogenesis during development and are essential for maintaining neuronal identity in adult neurons. Haploinsufficiency of EBF3 may affect brain development and function, resulting in developmental delay, intellectual disability, and behavioral differences observed in individuals with a deleterious variant in EBF3.

When the face says it all: dysmorphology in identifying syndromic causes of epilepsy.

Identifying the underlying cause of epilepsy often helps in choosing the appropriate management, suggests the long-term prognosis and clarifies the risk of the same condition in relatives. Epilepsy has many causes and a small but significant proportion of affected people have an identifiable genetic cause. Here, we discuss the role of genetic testing in adults with epilepsy, focusing on dysmorphic features noticeable on physical examination that might provide a strong clue to a specific genetic syndrome. We give illustrative examples of recognisable facial 'gestalt'. An astute clinician can recognise such clues and significantly shorten the process of making the underlying diagnosis in their patient.

The SATB2-associated syndrome is a recently described syndrome characterized by developmental delay/intellectual disability with absent or limited speech development, craniofacial abnormalities, behavioral problems, dysmorphic features, and palatal and dental abnormalities. Alterations of the SATB2 gene can result from a variety of different mechanisms that include contiguous deletions, intragenic deletions and duplications, translocations with secondary gene disruption, and point mutations. The multisystemic nature of this syndrome demands a multisystemic approach and we propose evaluation and management guidelines. The SATB2-associated syndrome registry has now been started and that will allow gathering further clinical information and refining the provided surveillance recommendations. © 2016 The Authors.

Axenfeld-Rieger syndrome (ARS) is a clinically and genetically heterogeneous group of autosomal dominantly inherited malformations that predominantly affect the eye but are also associated with craniofacial dysmorphism and dental abnormalities. A broad spectrum of genetic alterations involving PITX2 and FOXC1 lead to ARS. We report on a 4-year-old girl with clinical features of ARS and developmental delay due to a de novo apparently balanced pericentric inversion in chromosome 4. This report emphasizes that complementary investigations are necessary to precisely characterize chromosomal rearrangements. Elucidation of the exact genetic cause of ARS is important for comprehensive genetic counseling of the family members and for better patient management. © 2017 S. Karger AG, Basel.

Ring chromosome 15 [r(15)] is a rare condition with a mild-to-severe growth failure, mental disabilities, café-au-lait spots, specific facial features, fertility difficulties and other minor dysmorphic stigmata. Of almost 50 affected individuals reported in the literature, none were assessed for the precise breakpoint positioning, which creates uncertainty in defining a specific phenotype for the deleted segment. This study reports for the first time the vertical transmission of r(15) in three consecutive generations of a family, including a subfertile man, his mother and his newborn infant. Array comparative genomic hybridization results revealed a 563 kb deletion of 15q26.3, overlapping the OMIM genes SNRP1, PCSK6 and TM2D3. The hemizygosity was confirmed with real-time quantitative PCR. Regarding haploinsufficiency in 15q26.3, based on phenotypic characteristics of the carriers, the only rational conclusion is that SNRPA1, PCSK6 and TM2D3 are not gene-dosage sensitive and are probably inherited in an autosomal-recessive manner. Given growth deficiency in r(15) carriers, this shows that the growth retardation cannot be attributed entirely to IGF1R. The predominance of female patients with r(15) is the next as yet unanswered question; incomplete penetrance and/or variable expression of gene(s) in different genders may be involved, but further evidence is needed to support this idea.

Williams-Beuren syndrome (WBS) is caused by a hemizygous contiguous gene microdeletion of 1.55-1.84 Mb at 7q11.23 region. Approximately, 28 genes have been shown to contribute to classical phenotype of SWB with presence of dysmorphic facial features, supravalvular aortic stenosis (SVAS), intellectual disability, and overfriendliness. With the use of Microarray-based comparative genomic hybridization and other molecular cytogenetic techniques, is possible define with more accuracy partial or atypical deletion and refine the genotype-phenotype correlation. Here, we report on a rare genomic structural rearrangement in a boy with atypical deletion in 7q11.23 and XYY syndrome with characteristic clinical signs, but not sufficient for the diagnosis of WBS. Cytogenetic analysis of G-banding showed a karyotype 47,XYY. Analysis of DNA with the technique of MLPA (Multiplex Ligation-dependent Probe Amplification) using kits a combination of kits (P064, P036, P070, and P029) identified an atypical deletion on 7q11.23. In addition, high resolution SNP Oligonucleotide Microarray Analysis (SNP-array) confirmed the alterations found by MLPA and revealed others pathogenic CNVs, in the chromosomes 7 and X. The present report demonstrates an association not yet described in literature, between Williams-Beuren syndrome and 47,XYY. The identification of atypical deletion in 7q11.23 concomitant to additional pathogenic CNVs in others genomic regions allows a better comprehension of clinical consequences of atypical genomic rearrangements. © 2015 Wiley Periodicals, Inc.

Turner syndrome presents with one of the most frequent chromosomal aberrations in female, typically presented with growth retardation, ovarian insufficiency, facial dysmorphism, and numerous other somatic stigmata. Gigantism is an extremely rare condition resulting from an excessive growth hormone (GH) secretion that occurs during childhood before the fusion of epiphyseal growth plates. The major clinical feature of gigantism is growth acceleration, although these patients also suffer from hypogonadism and soft tissue hypertrophy. We presented a girl with mosaic Turner syndrome, delayed puberty and normal linear growth for the sex and age, due to the simultaneous GH hypersecretion by pituitary tumor. In the presented case all the typical phenotypic stigmata related to Turner syndrome were missing. Due to excessive pituitary GH secretion during the period while the epiphyseal growth plates of the long bones are still open, characteristic stagnation in longitudinal growth has not been demonstrated. The patient presented with delayed puberty and primary amenorrhea along with a sudden appearance of clinical signs of hypersomatotropinism, which were the reasons for seeking medical help at the age of 16. Physical examination of children presenting with delayed puberty but without growth arrest must include an overall hormonal and genetic testing even in the cases when typical clinical presentations of genetic disorder are absent. To the best of our knowledge, this is the first reported case of simultaneous presence of Turner syndrome and gigantism in the literature.

People with rare hypertrichosis syndromes became crowd-drawing money-making phenomena in many 19th century sideshow acts. These individuals have been referred to as dog-men, hair-men, and werewolves. In 1993, Baumister et al. described congenital hypertrichosis lanuginose or Ambras syndrome: a distinct form of congenital hypertrichosis characterized by excessive hair growth over the body and face associated with facial and occasional dental anomalies. Much is not known about this syndrome since fewer than 50 cases have been documented worldwide. In this case report, a nine year old girl presented with excessive hair growth throughout her body that was denser along her midline. Furthermore, her face displayed the typical dysmorphic features characteristic of Ambras syndrome: a round tip nose, thickened nasal cartilage, antiverted nares, prominent philtrum with deep groove, and a trapezoid mouth. Oral examination revealed normal oral mucosa with completely missing and unerupted decidious and permanent teeth. Panoramic radiographs confirmed unerupted deciduous teeth. Previous case reports have mentioned the presence of occasional dental anomalies such as retarded first and second dentition and absence of some teeth. However, this is the first reported case of Ambras syndrome presenting with complete anodontia. Prior cytogenetic studies performed on persons with Ambras syndrome have implicated a balanced pericentric inversion of chromosome 8. However, it is likely that dental anomalies are likely a result of a different genetic rearrangement. Further studies are needed to explore the cause of this rare phenotype of Ambras syndrome with complete unerupted dentition.

Circumferential skin creases Kunze type (CSC-KT) is a specific congenital entity with an unknown genetic cause. The disease phenotype comprises characteristic circumferential skin creases accompanied by intellectual disability, a cleft palate, short stature, and dysmorphic features. Here, we report that mutations in either MAPRE2 or TUBB underlie the genetic origin of this syndrome. MAPRE2 encodes a member of the microtubule end-binding family of proteins that bind to the guanosine triphosphate cap at growing microtubule plus ends, and TUBB encodes a β-tubulin isotype that is expressed abundantly in the developing brain. Functional analyses of the TUBB mutants show multiple defects in the chaperone-dependent tubulin heterodimer folding and assembly pathway that leads to a compromised yield of native heterodimers. The TUBB mutations also have an impact on microtubule dynamics. For MAPRE2, we show that the mutations result in enhanced MAPRE2 binding to microtubules, implying an increased dwell time at microtubule plus ends. Further, in vivo analysis of MAPRE2 mutations in a zebrafish model of craniofacial development shows that the variants most likely perturb the patterning of branchial arches, either through excessive activity (under a recessive paradigm) or through haploinsufficiency (dominant de novo paradigm). Taken together, our data add CSC-KT to the growing list of tubulinopathies and highlight how multiple inheritance paradigms can affect dosage-sensitive biological systems so as to result in the same clinical defect.

Describe the clinical and molecular findings of patients with Kabuki syndrome (KS) who present with hypoglycemia due to congenital hyperinsulinism (HI), and assess the incidence of KS in patients with HI. We documented the clinical features and molecular diagnoses of 10 infants with persistent HI and KS via a combination of sequencing and copy-number profiling methodologies. Subsequently, we retrospectively evaluated 100 infants with HI lacking a genetic diagnosis, for causative variants in KS genes. Molecular diagnoses of KS were established by identification of pathogenic variants in KMT2D (n = 5) and KDM6A (n = 5). Among the 100 infants with HI of unknown genetic etiology, a KS diagnosis was uncovered in one patient. The incidence of HI among patients with KS may be higher than previously reported, and KS may account for as much as 1% of patients diagnosed with HI. As the recognition of dysmorphic features associated with KS is challenging in the neonatal period, we propose KS should be considered in the differential diagnosis of HI. Since HI in patients with KS is well managed medically, a timely recognition of hyperinsulinemic episodes will improve outcomes, and prevent aggravation of the preexisting mild to moderate intellectual disability in KS.

The diphthamide biosynthesis 1 (DPH1) gene encodes one of the essential components of the enzyme catalyzing the first step of diphthamide formation on eukaryotic elongation factor 2 (EEF2). Diphthamide is the posttranslationally modified histidine residue on EEF2 that promotes protein chain elongation in the ribosome. DPH1 defects result in a failure of protein synthesis involving EEF2, leading to growth defects, embryonic lethality, and cell death. In humans, DPH1 mutations cause developmental delay with a short stature, dysmorphic features, and sparse hair, and are inherited in an autosomal recessive manner (MIM#616901). To date, only two homozygous missense mutations in DPH1 (c.17T>A, p.Met6Lys and c.701T>C, p.Leu234Pro) have been reported. We used WES to identify novel compound heterozygous mutations in DPH1 (c.289delG, p.Glu97Lysfs*8 and c.491T>C, p.Leu164Pro) in a patient from a nonconsanguineous family presenting with intellectual disability, a short stature, craniofacial abnormalities, and external genital abnormalities. The clinical phenotype of all patients with DPH1 mutations, including the current patient, revealed core features, although the external genital anomaly was newly recognized in our case.

Rubinstein–Taybi syndrome (RTS, OMIM 180849) and Filippi syndrome (FLPIS, OMIM 272440) are both rare syndromes, with multiple congenital anomalies and intellectual deficit (MCA/ID). We present a patient with intellectual deficit, short stature, bilateral syndactyly of hands and feet, broad thumbs, ocular abnormalities, and dysmorphic facial features. These clinical features suggest both RTS and FLPIS. Initial DNA analysis of DNA isolated from blood did not identify variants to confirm either of these syndrome diagnoses. Whole-exome sequencing identified a homozygous variant in C9orf173, which was novel at the time of analysis. Further Sanger sequencing analysis of FLPIS cases tested negative for CKAP2L variants did not, however, reveal any further variants. Subsequent analysis using DNA isolated from buccal mucosa revealed a mosaic variant in CREBBP. This report highlights the importance of excluding mosaic variants in patients with a strong but atypical clinical presentation of a MCA/ID syndrome if no disease-causing variants can be detected in DNA isolated from blood samples. As the striking syndactyly observed in the present case is typical for FLPIS, we suggest CREBBP analysis in saliva samples for FLPIS syndrome cases in which no causal CKAP2L variant is detected.

We observed a complex atlas (C1) dysmorphism in a human medieval skeleton dug up from the sixth to the seventh century necropolis located in the north-eastern Italy. We analyzed such a dysmorphism in the light of pertinent literature and discussed the functional and clinical implications related to this type of C1 structural malformation. Macroscopical and CT-SCAN examinations of the atlas were carried out. Bone findings consisted of partial aplasia of the posterior arch of the C1 accompanied by a bilateral arcuate foramen. In addition, the spinous processes of C7 and T1 were found to be bifid. Although such abnormalities are supposed to be clinically inconspicuous, yet they may become challenging or even dangerous in the context of trauma. They may even complicate specific diagnostic or surgical procedures. In addition, they may cause a great number of symptoms, ranging from headache and neck pain to loss of postural muscle tone and consciousness, due to the close and complex relationship of bone structures with nerves, blood vessels, muscles, and ligaments. As a result, radiologists, clinicians, surgeons, and chiropractors should consider in their clinical reasoning the possibility that atlas dysmorphisms may occur.

In Vitro Protective Effect of Phikud Navakot Extraction on Erythrocyte

PubMed Central

2016-01-01

Phikud Navakot (PN), Thai herbal remedy in National List of Essential Medicines, has been claimed to reduce many cardiovascular symptoms especially dizziness and fainting. Apart from blood supply, erythrocyte morphology, in both shape and size, is one of the main consideration factors in cardiovascular diseases and may be affected by vascular oxidative stress. However, little is known about antioxidative property of PN on erythrocyte to preserve red blood cell integrity. In this study, 1,000 μM hydrogen peroxide-induced oxidative stress was conducted on sheep erythrocyte. Three doses of PN (1, 0.5, and 0.25 mg/mL) and 10 μM of ascorbic acid were compared. The released hemoglobin absorbance was measured to demonstrate hemolysis. Electron microscopic and immunohistochemical studies were also performed to characterize dysmorphic erythrocyte and osmotic ability in relation to aquaporin- (AQP-) 1 expression, respectively. The results revealed that all doses of PN and ascorbic acid decreased the severity of dysmorphic erythrocyte, particularly echinocyte, acanthocyte, knizocyte, codocyte, clumping, and other malformations. However, the most effective was 0.5 mg/mL PN dosage. In addition, hydrostatic pressure may be increased in dysmorphic erythrocyte in association with AQP-1 upregulation. Our results demonstrated that PN composes antioxidative effect to maintain the integrity and osmotic ability on sheep erythrocyte. PMID:28003847

To evaluate the efficacy of therapist guided internet based cognitive behavioural therapy (CBT) programme for body dysmorphic disorder (BDD-NET) compared with online supportive therapy. A 12 week single blind parallel group randomised controlled trial. Academic medical centre. 94 self referred adult outpatients with a diagnosis of body dysmorphic disorder and a modified Yale-Brown obsessive compulsive scale (BDD-YBOCS) score of ≥ 20. Concurrent psychotropic drug treatment was permitted if the dose had been stable for at least two months before enrolment and remained unchanged during the trial. Participants received either BDD-NET (n=47) or supportive therapy (n=47) delivered via the internet for 12 weeks. The primary outcome was the BDD-YBOCS score after treatment and follow-up (three and six months from baseline) as evaluated by a masked assessor. Responder status was defined as a ≥ 30% reduction in symptoms on the scale. Secondary outcomes were measures of depression (MADRS-S), global functioning (GAF), clinical global improvement (CGI-I), and quality of life (EQ5D). The six month follow-up time and all outcomes other than BDD-YBOCS and MADRS-S at 3 months were not pre-specified in the registration at clinicaltrials.gov because of an administrative error but were included in the original trial protocol approved by the regional ethics committee before the start of the trial. BDD-NET was superior to supportive therapy and was associated with significant improvements in severity of symptoms of body dysmorphic disorder (BDD-YBOCS group difference -7.1 points, 95% confidence interval -9.8 to -4.4), depression (MADRS-S group difference -4.5 points, -7.5 to -1.4), and other secondary measures. At follow-up, 56% of those receiving BDD-NET were classed as responders, compared with 13% receiving supportive therapy. The number needed to treat was 2.34 (1.71 to 4.35). Self reported satisfaction was high. CBT can be delivered safely via the internet to patients with body dysmorphic disorder. BDD-NET has the potential to increase access to evidence based psychiatric care for this mental disorder, in line with NICE priority recommendations. It could be particularly useful in a stepped care approach, in which general practitioner or other mental health professionals can offer treatment to people with mild to moderate symptoms at low risk of suicide.Trial registration ClinicalTrials.gov ID: NCT02010619.

Analysis of 22q11.2 deletions by FISH in a series of velocardiofacial syndrome patients

Ravnan, J.B.; Golabi, M.; Lebo, R.V.

Deletions in chromosome 22 band q11.2 have been associated with velocardiofacial (VCF or Shprintzen) syndrome and the DiGeorge anomaly. A study of VCF patients evaluated at the UCSF Medical Center was undertaken to correlate disease phenotype with presence or absence of a deletion. Patients referred for this study had at least two of the following: dysmorphic facial features, frequent ear infections or hearing loss, palate abnormalities, thymic hypoplasia, hypocalcemia, congenital heart defect, hypotonia, and growth or language delay. Fluorescence in situ hybridization (FISH) using the DiGeorge critical region probe N25 was used to classify patients according to the presence ormore » absence of a deletion in 22q11.2, and the results were compared to clinical characteristics. We have completed studies on 58 patients with features of VCF. Twenty-one patients (36%) were found to have a deletion in 22q11.2 by FISH. A retrospective study of archived slides from 14 patients originally studied only by prometaphase GTG banding found six patients had a deletion detected by FISH; of these, only two had a microscopically visible chromosome deletion. Our study of 11 sets of parents of children with the deletion found two clinically affected mothers with the deletion, including one with three of three children clinically affected. A few patients who did not fit the classical VCF description had a 22q11.2 deletion detected by FISH. These included one patient with both cleft lip and palate, and another with developmental delay and typical facial features but no cardiac or palate abnormalities. Both patients with the DiGeorge anomaly as part of VCF had the deletion. On the other hand, a number of patients diagnosed clinically with classical VCF did not have a detectable deletion. This raises the question whether they represent a subset of patients with a defect of 22q11.2 not detected by the N25 probe, or whether they represent a phenocopy of VCF.« less

Social anxiety disorder (SAD) and body dysmorphic disorder (BDD) are two separate, but conceptually overlapping nosological entities. In this review, we examine similarities between SAD and BDD in comorbidity, phenomenology, cognitive biases, treatment outcome, and cross-cultural aspects. Our review suggests that SAD and BDD are highly comorbid, show a similar age of onset, share a chronic trajectory, and show similar cognitive biases for interpreting ambiguous social information in a negative manner. Furthermore, research from treatment outcome studies have demonstrated that improvements in SAD were significantly correlated with improvements in BDD. Findings from cross-cultural research suggest that BDD may be conceived as a subtype of SAD in some Eastern cultures. Directions for future research and clinical implications of these findings are discussed. PMID:20817336

Objective Cross-sectional/retrospective data have indicated that individuals with body dysmorphic disorder (BDD) have high rates of suicidal ideation and attempts. However, no study, to the authors' knowledge, has prospectively examined suicidality in BDD. Method In the first prospective study of BDD's course, the authors examined suicidality in 185 subjects for up to 4 years. Results Suicidal ideation was reported by a mean of 57.8% of the subjects per year, and a mean of 2.6% attempted suicide per year. Two subjects (0.3% per year) completed suicide. Conclusions Individuals with BDD have high rates of suicidal ideation and attempts. The completed suicide rate is preliminary but suggests that the rate of completed suicide in BDD is markedly high.

Transsacral Osseous Corridor Anatomy Is More Amenable To Screw Insertion In Males: A Biomorphometric Analysis of 280 Pelves.

Percutaneous iliosacral screw placement is the standard procedure for fixation of posterior pelvic ring lesions, although a transsacral screw path is being used more frequently in recent years owing to increased fracture-fixation strength and better ability to fix central and bilateral sacral fractures. However, biomorphometric data for the osseous corridors are limited. Because placement of these screws in a safe and effective manner is crucial to using transsacral screws, we sought to address precise sacral anatomy in more detail to look for anatomic variation in the general population. We asked: (1) What proportion of healthy pelvis specimens have no transsacral corridor at the level of the S1 vertebra owing to sacral dysmorphism? (2) If there is no safe diameter for screw placement in the transsacral S1 corridor, is an increased and thus safe diameter of the transsacral S2 corridor expected? (3) Are there sex-specific differences in sacral anatomy and are these correlated with known anthropometric parameters? CT scans of pelves of 280 healthy patients acquired exclusively for medical indications such as polytrauma (20%), CT angiography (70%), and other reasons (10%), were segmented manually. Using an advanced CT-based image analysis system, the mean shape of all segmented pelves was generated and functioned as a template. On this template, the cylindric transsacral osseous corridor at the level of the S1 and S2 vertebrae was determined manually. Each pelvis then was registered to the template using a free-form registration algorithm to measure the maximum screw corridor diameters on each specimen semiautomatically. Thirty of 280 pelves (11%) had no transsacral S1 corridor owing to sacral dysmorphism. The average of maximum cylindrical diameters of the S1 corridor for the remaining 250 pelves was 12.8 mm (95% CI, 12.1-13.5 mm). A transverse corridor for S2 was found in 279 of 280 pelves, with an average of maximum cylindrical diameter of 11.6 mm (95% CI, 11.3-11.9 mm). Decreasing transsacral S1 corridor diameters are correlated with increasing transsacral S2 corridor diameters (R value for females, -0.260, p < 0.01; for males, -0.311, p < 0.001). Female specimens were more likely to have sacral dysmorphism (defined as a pelvis without a transsacral osseous corridor at the level of the S1 vertebra) than were male specimens (females, 16%; males, 7%; p < 0.003). Furthermore female pelves had smaller-corridor diameters than did male pelves (females versus males for S1: 11.7 mm [95% CI, 10.6-12.8 mm] versus 13.5 mm [95% CI, 12.6-14.4 mm], p < 0.01; and for S2: 10.6 mm [95% CI, 10.1-11.1 mm] versus 12.2 mm [95% CI, 11.8-12.6 mm ], p < 0.0001). Narrow corridors and highly individual, sex-dependent variance of morphologic features of the sacrum make transsacral implant placement technically demanding. Individual preoperative axial-slice CT scan analyses and orthogonal coronal and sagittal reformations are recommended to determine the prevalence of sufficient-sized osseous corridors on both levels for safe screw placements, especially in female patients, owing to their smaller corridor diameters and higher rate of sacral dysmorphism.

An investigation of the transdiagnostic model of eating disorders in the context of muscle dysmorphia.

Muscle dysmorphia is a psychiatric disorder that has been conceptually linked to eating disorders, although its precise nosology remains unclear. To further investigate this notion, the present study examined the applicability of the transdiagnostic model of eating disorders to muscle dysmorphia. One hundred and nineteen male undergraduate students completed self-report measures of multidimensional perfectionism, mood intolerance, self-esteem, interpersonal problems, and muscle dysmorphia symptomatology. Self-oriented perfectionism, socially prescribed perfectionism, mood intolerance, and low self-esteem significantly predicted muscle dysmorphia symptomatology, whereas other-oriented perfectionism and interpersonal problems did not demonstrate significant predictive value when accounting for the other transdiagnostic constructs. The transdiagnostic model of eating disorders may potentially be applied to enhance our understanding of the maintenance of muscle dysmorphic features in addition to eating disorder symptomatology.

Gorlin-Goltz syndrome is an uncommon autosomal dominant inherited disorder, which is characterized by multiple odontogenic Keratocysts and basal cell carcinomas, skeletal, dental, ophthalmic, and neurological abnormalities, intracranial ectopic calcifications of the falx cerebri, and facial dysmorphism. Pathogenesis of the syndrome is attributed to abnormalities in the long arm of chromosome 9 (q22.3-q31) and loss or mutations of human patched gene (PTCH1 gene). Diagnosis is based upon established major and minor clinical and radiological criteria and ideally confirmed by deoxyribo nucleic acid analysis. We report a case of a 9-year-old girl presenting with three major and one minor feature of Gorlin-Goltz syndrome. Radiologic findings of the syndrome are easily identifiable on Orthopantomogram, chest X-ray, and Computed tomography scans. These investigations prompt an early verification of the disease, which is very important to prevent recurrence and better survival rates from the coexistent diseases.

Dentofacial anomalies may guide us to the diagnosis of many congenital and hereditary syndromes. A 9-year-old boy was diagnosed with Nance–Horan syndrome. This syndrome is an extremely rare X-linked genetic disorder which is entirely expressed in males with semi-dominant transmission which results from mutations occurring in male gametes. It is characterized by facial dysmorphism such as long face, prominent nose and mandibular prognathism, ocular abnormalities such as congenital cataract, microcornea, microphthalmia and strabismus, and dental anomalies including mulberry molars and screwdriver-shaped incisors. Heterozygous females inherit this disease and also suffer from this syndrome but in a milder form. Approximately one-third of the affected males show signs of developmental delay and intellectual abnormalities. This syndrome is very rare and the incidence of the disease has not been established so far. The present article describes the clinical and radiological features and the genetic implications of this syndrome. PMID:29042737

Twenty-six families with keratinopathic ichthyoses (epidermolytic ichthyosis, superficial epidermolytic ichthyosis or congenital reticular ichthyosiform erythroderma) were studied. Epidermolytic ichthyosis is caused by mutations in the genes KRT1 or KRT10, mutations in the gene KRT2 lead to superficial epidermolytic ichthyosis, and congenital reticular ichthyosiform erythroderma is caused by frameshift mutations in the genes KRT10 or KRT1, which lead to the phenomenon of revertant mosaicism. In this study mutations were found in KRT1, KRT2 and KRT10, including 8 mutations that are novel pathogenic variants. We report here the first case of a patient with congenital reticular ichthyosiform erythroderma carrying a mutation in KRT10 that does not lead to an arginine-rich reading frame. Novel clinical features found in patients with congenital reticular ichthyosiform erythroderma are described, such as mental retardation, spasticity, facial dysmorphisms, symblepharon and malposition of the 4th toe.

Using whole-exome sequencing, we identified seven unrelated individuals with global developmental delay, hypotonia, dysmorphic facial features, and an increased frequency of short stature, ataxia, and autism with de novo heterozygous frameshift, nonsense, splice, and missense variants in the Early B-cell Transcription Factor Family Member 3 ( EBF3 ) gene. EBF3 is a member of the collier/olfactory-1/early B-cell factor (COE) family of proteins, which are required for central nervous system (CNS) development. COE proteins are highly evolutionarily conserved and regulate neuronal specification, migration, axon guidance, and dendritogenesis during development and are essential for maintaining neuronal identity in adult neurons. Haploinsufficiency of EBF3 may affect brain development and function, resulting in developmental delay, intellectual disability, and behavioral differences observed in individuals with a deleterious variant in EBF3 . © 2017 Tanaka et al.; Published by Cold Spring Harbor Laboratory Press.

Terminal deletion of chromosome 6q is a rare chromosomal abnormality associated with variable phenotype spectrum. Although intellectual disability, facial dysmorphism, seizures and brain abnormalities are typical features of this syndrome, genotype–phenotype correlation needs to be better understood. We report the case of a 6-year-old Caucasian boy with a clinical diagnosis of intellectual disability, delayed language development and dyspraxia who carries an approximately 8 Mb de novo heterozygous microdeletion in the 6q26-q27 locus identified by karyotype and defined by high-resolution SNP-array analysis. This patient has no significant structural brain or other organ malformation, and he shows a very mild phenotype compared to similar 6q26-qter deletion. The patient phenotype also suggests that a dyspraxia susceptibility gene is located among the deleted genes. PMID:29270193

Smith-Magenis syndrome (SMS), the result of an interstitial deletion within chromosome 17p11.2, is a disorder that may include minor dysmorphic features, brachydactyly, short stature, hypotonia, speech delays, cognitive deficits, signs of peripheral neuropathy, scoliosis, and neurobehavioral problems including sleep disturbances and maladaptive repetitive and self-injurious behaviors. Physical and occupational therapists provide services for children who have the syndrome, whose genetic disorder is frequently not identified or diagnosed before 1 year of age. A comprehensive physical and occupational therapy evaluation was completed in nonidentical twins with one having SMS, using the Sensory Profile; Brief Assessment of Motor Function (BAMF); Peabody Developmental Motor Scales, Second Edition (PDMS-2); and Pediatric Evaluation of Disability Inventory (PEDI). This provides a framework for conducting assessments to enhance early detection and interdisciplinary management with this specialized population.

Ehlers-Danlos syndrome classical type is a connective tissue disorder characterized by skin hyperextensibility, atrophic scarring, and joint hypermobility. The condition typically results from mutations in COL5A1 or COL5A2 leading to the functional haploinsufficiency. Here, we report of a 24-year-old male with mild intellectual disability, dysmorphic features, and a phenotype consistent with Ehlers-Danlos syndrome classical type. A copy number variant-calling algorithm from panel sequencing data identified the deletions exons 2-11 and duplications of exons 12-67 within COL5A1. Array comparative genomic hybridization confirmed a 94 kb deletion at 9q34.3 involving exons 2-11 of COL5A1, and a 3.4 Mb duplication at 9q34.3 involving exons 12-67 of COL5A1. © 2018 Japanese Teratology Society.

What people with Down Syndrome can teach us about cardiopulmonary disease.

PubMed

Colvin, Kelley L; Yeager, Michael E

2017-01-01

Down syndrome is the most common chromosomal abnormality among live-born infants. Through full or partial trisomy of chromosome 21, Down syndrome is associated with cognitive impairment, congenital malformations (particularly cardiovascular) and dysmorphic features. Immune disturbances in Down syndrome account for an enormous disease burden ranging from quality-of-life issues (autoimmune alopecia) to more serious health issues (autoimmune thyroiditis) and life-threatening issues (leukaemia, respiratory tract infections and pulmonary hypertension). Cardiovascular and pulmonary diseases account for ∼75% of the mortality seen in persons with Down syndrome. This review summarises the cardiovascular, respiratory and immune challenges faced by individuals with Down syndrome, and the genetic underpinnings of their pathobiology. We strongly advocate increased comparative studies of cardiopulmonary disease in persons with and without Down syndrome, as we believe these will lead to new strategies to prevent and treat diseases affecting millions of people worldwide.

Floating-Harbor Syndrome (FHS; OMIM #136140) is an ultra-rare autosomal dominant genetic condition characterized by expressive language delay, short stature with delayed bone mineralization, a triangular face with a prominent nose, and deep-set eyes, and hand anomalies. First reported in 1973, FHS is associated with mutations in the SRCAP gene, which encodes SNF2-related CREBBP activator protein. Mutations in the CREBBP gene cause Rubinstein-Taybi Syndrome (RSTS; OMIM #180849, #613684), another rare disease characterized by broad thumbs and halluces, facial dysmorphisms, short stature, and intellectual disability, which has a phenotypic overlap with FHS. We describe a case of FHS associated with a novel SRCAP mutation and characterized by Perthes disease, a skeletal anomaly described in approximately 3% of patients with RSTS. Thus Perthes disease can be added to the list of clinical features that overlap between FHS and RSTS. © 2018 Wiley Periodicals, Inc.

Hereditary congenital facial paresis (HCFP) is characterized by isolated dysfunction of the facial nerve (CN VII) due to congenital cranial dysinnervation disorders. HCFP has genetic heterogeneity and HOXB1 is the first identified gene. We report the clinical, radiologic and molecular investigations of three patients admitted for HCFP in a large consanguineous Turkish family. High-throughput sequencing and Sanger sequencing of all patients revealed a novel homozygous mutation p.Arg230Trp (c.688C>T) within the HOXB1 gene. The report of the mutation brings the total number of HOXB1 mutations identified in HCFP to four. The results of this study emphasize that in individuals with congenital facial palsy accompanied by hearing loss and dysmorphic facial features, HOXB1 mutation causing HCFP should be kept in mind.

Noonan syndrome is a relatively common, clinically variable developmental disorder. Cardinal features include postnatally reduced growth, distinctive facial dysmorphism, congenital heart defects and hypertrophic cardiomyopathy, variable cognitive deficit and skeletal, ectodermal and hematologic anomalies. Noonan syndrome is transmitted as an autosomal dominant trait, and is genetically heterogeneous. So far, heterozygous mutations in nine genes (PTPN11, SOS1, KRAS, NRAS, RAF1, BRAF, SHOC2, MEK1 and CBL) have been documented to underlie this disorder or clinically related phenotypes. Based on these recent discoveries, the diagnosis can now be confirmed molecularly in approximately 75% of affected individuals. Affected genes encode for proteins participating in the RAS-mitogen-activated protein kinases (MAPK) signal transduction pathway, which is implicated in several developmental processes controlling morphology determination, organogenesis, synaptic plasticity and growth. Here, we provide an overview of clinical aspects of this disorder and closely related conditions, the molecular mechanisms underlying pathogenesis, and major genotype-phenotype correlations.

Ocular anomalies have been frequently reported in Noonan syndrome. Anterior segment anomalies have been described in 57% of PTPN11 positive patients, with the most common findings being corneal changes and in particular, prominent corneal nerves and cataracts. We report on a neonate with a confirmed PTPN11 mutation and ocular findings consistent with Axenfeld anomaly. The patient initially presented with non-immune hydrops and subsequently developed hypertrophic cardiomyopathy and dysmorphic features typical of Noonan syndrome. While a pathogenic mutation in PTPN11 was confirmed, prior testing for the two common genes associated with Axenfeld-Rieger syndrome, PITX2, and FOXC1 was negative. This finding expands the spectrum of anterior chamber anomalies seen in Noonan syndrome and perhaps suggests a common neural crest related mechanism that plays a critical role in the development of the eye and other organs. © 2014 Wiley Periodicals, Inc.

Fractures are an important entity to consider in pediatric patients. There are certain diseases in which bones fracture with a minimal trauma. Pycnodysostosis is an autosomal recessive unusual type of cráneo metaphyseal dysplasia, that presents frequently as fracture in a pathological bone. A 9 year old caucasian female, diagnosed with pycnodysostosis, was admitted with a right femur fracture as a result of a low energy trauma. Radiographic studies showed bilateral femur fractures, proximal fracture and non-union in antecurvatum of the left tibia. Pycnodysostosis is a rare disease, generally diagnosed at an early age by growth restriction, frequent fractures or fractures with low energy trauma. Therapy alternatives are limited, and no permanent cure has been developed. If a patient has dysmorphic facial features and fractures in a pathological bone, it is important to suspect bone dysplasia, such as pycnodysostosis and its differential diagnoses.

Novel cAMP binding protein-BP (CREBBP) mutation in a girl with Rubinstein-Taybi syndrome, GH deficiency, Arnold Chiari malformation and pituitary hypoplasia

PubMed Central

2013-01-01

Background Rubinstein-Taybi syndrome (RTS) is a rare autosomal dominant disorder (prevalence 1:125,000) characterised by broad thumbs and halluces, facial dysmorphism, psychomotor development delay, skeletal defects, abnormalities in the posterior fossa and short stature. The known genetic causes are point mutations or deletions of the cAMP-response element binding protein-BP (CREBBP) (50-60% of the cases) and of the homologous gene E1A-binding protein (EP300) (5%). Case presentation We describe, for the first time in literature, a RTS Caucasian girl, 14-year-old, with growth hormone (GH) deficiency, pituitary hypoplasia, Arnold Chiari malformation type 1, double syringomyelic cavity and a novel CREBBP mutation (c.3546insCC). Conclusion We hypothesize that CREBBP mutation we have identified in this patient could be responsible also for RTS atypical features as GH deficiency and pituitary hypoplasia. PMID:23432975

The normal-equivalent: a patient-specific assessment of facial harmony.

Evidence-based practice in oral and maxillofacial surgery would greatly benefit from an objective assessment of facial harmony or gestalt. Normal reference faces have previously been introduced, but they describe harmony in facial form as an average only and fail to report on harmonic variations found between non-dysmorphic faces. In this work, facial harmony, in all its complexity, is defined using a face-space, which describes all possible variations within a non-dysmorphic population; this was sampled here, based on 400 healthy subjects. Subsequently, dysmorphometrics, which involves the measurement of morphological abnormalities, is employed to construct the normal-equivalent within the given face-space of a presented dysmorphic face. The normal-equivalent can be seen as a synthetic identical but unaffected twin that is a patient-specific and population-based normal. It is used to extract objective scores of facial discordancy. This technique, along with a comparing approach, was used on healthy subjects to establish ranges of discordancy that are accepted to be normal, as well as on two patient examples before and after surgical intervention. The specificity of the presented normal-equivalent approach was confirmed by correctly attributing abnormality and providing regional depictions of the known dysmorphologies. Furthermore, it proved to be superior to the comparing approach. Copyright © 2013 International Association of Oral and Maxillofacial Surgeons. Published by Elsevier Ltd. All rights reserved.

Variable expressivity of the phenotype in two families with brachydactyly type E, craniofacial dysmorphism, short stature and delayed bone age caused by novel heterozygous mutations in the PTHLH gene.

Brachydactyly refers to shortening of digits due to hypoplasia or aplasia of bones forming the hands and/or feet. Isolated brachydactyly type E (BDE), which is characterized by shortened metacarpals and/or metatarsals, results in a small proportion of patients from HOXD13 or PTHLH mutations, although in the majority of cases molecular lesion remains unknown. BDE, like other brachydactylies, shows clinical heterogeneity with highly variable intrafamilial and interindividual expressivity. In this study, we investigated two Polish cases (one familial and one sporadic) presenting with BDE and additional symptoms due to novel PTHLH mutations. Apart from BDE, the affected family showed short stature, mild craniofacial dysmorphism and delayed bone age. Sanger sequencing of PTHLH revealed a novel heterozygous frameshift mutation c.258delC(p.N87Tfs*18) in two affected individuals and one relative manifesting mild brachydactyly. The sporadic patient, in addition to BDE, presented with craniofacial dysmorphism, normal stature and bone age, and was demonstrated to carry a de novo heterozygous c.166C>T(p.R56*) mutation. Our paper reports on the two novel truncating PTHLH variants, resulting in variable combination of BDE and other symptoms. Data shown here expand the knowledge on the phenotypic presentation of PTHLH mutations, highlighting significant clinical variability and incomplete penetrance of the PTHLH-related symptoms.

The SATB2-associated syndrome (SAS) was proposed recently, after the SATB2 gene was initially discovered to be associated with isolated cleft palate. This syndrome is characterized by intellectual disability with delayed speech development, facial dysmorphism, cleft or high-arched palate, and dentition problems. Here, we describe two novel SATB2 sequence variants in two unrelated patients presenting with Rett-like phenotypes. We performed trio-based whole-exome sequencing in a 17-month-old girl presenting with severe retardation and Rett-like phenotypes, which revealed a de novo missense variant in SATB2 (p.Glu396Gln). Moreover, targeted sequencing of the SATB2 gene was performed in a 2-year-old girl with severe psychomotor retardation, facial hypotonia, and cleft palate who also exhibited some features of Rett syndrome. A nonsense variant in SATB2 was identified in this patient (p.Arg459*). This study expanded the clinical and genetic spectrum of SAS. SATB2 variants should be considered in cases with psychomotor retardation alone or in any cases with Rett-like phenotypes, regardless of the typical features of SAS such as cleft palate. © 2015 John Wiley & Sons A/S.

Whole-exome sequencing (WES) represents a significant breakthrough in clinical genetics, and identifies a genetic etiology in up to 30% of cases of intellectual disability (ID). Using WES, we identified seven unrelated patients with a similar clinical phenotype of severe intellectual disability or neurodevelopmental delay who were all heterozygous for de novo truncating variants in the AT-hook DNA-binding motif-containing protein 1 (AHDC1). The patients were all minimally verbal or nonverbal and had variable neurological problems including spastic quadriplegia, ataxia, nystagmus, seizures, autism, and self-injurious behaviors. Additional common clinical features include dysmorphic facial features and feeding difficulties associated with failure to thrive and short stature. The AHDC1 gene has only one coding exon, and the protein contains conserved regions including AT-hook motifs and a PDZ binding domain. We postulate that all seven variants detected in these patients result in a truncated protein missing critical functional domains, disrupting interactions with other proteins important for brain development. Our study demonstrates that truncating variants in AHDC1 are associated with ID and are primarily associated with a neurodevelopmental phenotype.

Hypomyelinating leukodystrophies (HLDs) affect the white matter of the central nervous system and manifest as neurological disorders. They are genetically heterogeneous. Very recently, biallelic variants in NKX6-2 have been suggested to cause a novel form of autosomal recessive HLD. Using whole-exome or whole-genome sequencing, we identified the previously reported c.196delC and c.487C>G variants in NKX6-2 in 3 and 2 unrelated index cases, respectively; the novel c.608G>A variant was identified in a sixth patient. All variants were homozygous in affected family members only. Our patients share a primary diagnosis of psychomotor delay, and they show spastic quadriparesis, nystagmus and hypotonia. Seizures and dysmorphic features (observed in 2 families each) represent an addition to the phenotype, while developmental regression (observed in 3 families) appears to be a notable and previously underestimated clinical feature. Our findings extend the clinical and mutational spectra associated with this novel form of HLD. Comparative analysis of our 10 patients and the 15 reported previously did, however, not reveal clear evidence for a genotype-phenotype correlation. © 2018 John Wiley & Sons A/S.

Gerodermia osteodysplastica (GO) is a connective tissue disorder characterized by premature aging, wrinkled, and lax skin with reduced elasticity which is more marked on the dorsum of the hands and feet associated with hyperextensible joints and osteoporosis. The wrinkly skin syndrome (WSS) is characterized by wrinkled skin over the dorsum of the hands, feet, and abdomen; hyperextensible joints, particularly of the hands; intrauterine growth retardation; postnatal failure to thrive; and mental and developmental delay. We report on five children from two consanguineous Arab families with features overlapping both GO and WSS. All five children had similar dysmorphic facial features consisting of broad and prominent forehead, hypotelorism with epicanthal folds, prominent bulbous nose, flat malar region, and large protruding ears. All had wrinkling of the skin more marked on the dorsum of the hands, feet, and abdomen; hyperextensibility of the joints, particularly of the hands; and aged appearance. Intrauterine growth retardation, subsequent failure to thrive, developmental delay, and variable degree of osteoporosis was also present in all of them. The older three children developed progressive prognathism. We suggest that GO and WSS could represent variable manifestation of the same disorder. Copyright 2001 Wiley-Liss, Inc.

Intellectual disability (ID) affects approximately 1-2% of the general population and is characterized by impaired cognitive abilities. ID is both clinically as well as genetically heterogeneous, up to 2000 genes are estimated to be involved in the emergence of the disease with various clinical presentations. For many genes, only a few patients have been reported and causality of some genes has been questioned upon the discovery of apparent loss-of-function mutations in healthy controls. Description of additional patients strengthens the evidence for the involvement of a gene in the disease and can clarify the clinical phenotype associated with mutations in a particular gene. Here, we present two large four-generation families with a total of 11 males affected with ID caused by mutations in ZNF711, thereby expanding the total number of families with ID and a ZNF711 mutation to four. Patients with mutations in ZNF711 all present with mild to moderate ID and poor speech accompanied by additional features in some patients, including autistic features and mild facial dysmorphisms, suggesting that ZNF711 mutations cause non-syndromic ID.

Here we report the smallest deletion involving SNURF/SNRPN that causes major symptoms of Prader-Willi syndrome (PWS), including hypotonia, dysmorphic features, intellectual disability, and obesity. A female patient with the aforementioned and additional features was referred to the Mayo Clinic Cytogenetics laboratory for genetic testing. Chromosomal microarray analysis and subsequent Sanger sequencing identified a de novo 6.4 kb deletion at 15q11.2, containing exon 1 of the SNURF gene and exon 1 of the shortest isoform of the SNRPN gene. SNURF/SNRPN exon 1, which is methylated on the silent maternal allele, is associated with acetylated histones on the expressed paternal allele. This region also overlaps with the PWS-imprinting center (IC). Subsequent molecular methylation analysis was performed using methylation-specific MLPA (MS-MLPA), which characterized that the deletion of SNURF/SNRPN exon 1 was paternal in origin, consistent with the PWS-like phenotype. Since SNURF/SNRPN gene and the PWS-IC are known to regulate snoRNAs, it is likely that the PWS-like phenotype observed in patients with paternal SNURF/SNRPN deletion is due to the disrupted expression of SNORD116 snoRNAs.

Ichthyosis and neurological involvement occur in relatively few known Mendelian disorders caused by mutations in genes relevant both for epidermis and neural function. To identify the cause of a similar phenotype of ichthyotic keratoderma, spasticity, mild hypomyelination (on MRI) and dysmorphic features (IKSHD) observed in two unrelated paediatric probands without family history of disease. Whole exome sequencing was performed in both patients. The functional effect of prioritised variant in ELOVL1 (very-long-chain fatty acids (VLCFAs) elongase) was analysed by VLCFA profiling by gas chromatography-mass spectrometry in stably transfected HEK2932 cells and in cultured patient's fibroblasts. Probands shared novel heterozygous ELOVL1 p.Ser165Phe mutation (de novo in one family, while in the other family, father could not be tested). In transfected cells p.Ser165Phe: (1) reduced levels of FAs C24:0-C28:0 and C26:1 with the most pronounced effect for C26:0 (P=7.8×10 -6  vs HEK293 cells with wild type (wt) construct, no difference vs naïve HEK293) and (2) increased levels of C20:0 and C22:0 (P=6.3×10 -7 , P=1.2×10 -5 , for C20:0 and C22:0, respectively, comparison vs HEK293 cells with wt construct; P=2.2×10 -7 , P=1.9×10 -4 , respectively, comparison vs naïve HEK293). In skin fibroblasts, there was decrease of C26:1 (P=0.014), C28:0 (P=0.001) and increase of C20:0 (P=0.033) in the patient versus controls. There was a strong correlation (r=0.92, P=0.008) between the FAs profile of patient's fibroblasts and that of p.Ser165Phe transfected HEK293 cells. Serum levels of C20:0-C26:0 FAs were normal, but the C24:0/C22:0 ratio was decreased. The ELOVL1 p.Ser165Phe mutation is a likely cause of IKSHD. © Article author(s) (or their employer(s) unless otherwise stated in the text of the article) 2018. All rights reserved.

A de-novo interstitial microduplication involving 2p16.1-p15 and mirroring 2p16.1-p15 microdeletion syndrome: Clinical and molecular analysis.

Microdeletions of various sizes in the 2p16.1-p15 chromosomal region have been grouped together under the 2p16.1-p15 microdeletion syndrome. Children with this syndrome generally share certain features including microcephaly, developmental delay, facial dysmorphism, urogenital and skeletal abnormalities. We present a child with a de-novo interstitial 1665 kb duplication of 2p16.1-p15. Clinical features of this child are distinct from those of children with the 2p16.1-p15 microdeletion syndrome, specifically the head circumference which is within the normal range and mild intellectual disability with absence of autistic behaviors. Microduplications many times bear milder clinical phenotypes in comparison with corresponding microdeletion syndromes. Indeed, as compared to the microdeletion syndrome patients, the 2p16.1-p15 microduplication seems to have a milder cognitive effect and no effect on other body systems. Limited information available in genetic databases about cases with overlapping duplications indicates that they all have abnormal developmental phenotypes. The involvement of genes in this location including BCL11A, USP34 and PEX13, affecting fundamental developmental processes both within and outside the nervous system may explain the clinical features of the individual described in this report.

The trisomy 18 syndrome occurs due to the presence of an extra chromosome 18 in most cases. The prevalence in infants is estimated at 1:6000 to 1:8000. Those affected have a high mortality rate, only 4% may survive their first year of life. There are few reported cases exceeding five years of age. The aim of this paper is to report a case of trisomy 18 of long survival with oral cavity features not described in the literature, and to provide information to physicians and paediatricians about aetiology, phenotype, survival and genetic counselling. A 7 year-old female patient with 2 karyotypes performed by lymphocyte culture showing 47XX+18 in all metaphases. She presented with growth deficiency, dysmorphic facies, severe psychomotor retardation and cognitive disability, inability to feed, lack of verbal language, sensorineural hearing loss, ataxia, cerebellar hypoplasia, and genitals with hypoplastic labia majora and minora. In the oral cavity: dome shaped palate, macroglossia, absence of upper central incisors and first upper and lower molars in mouth. X-ray findings showed formation of missing teeth, with late eruption being concluded. In cases of trisomy 18 syndrome there is an increased risk of neonatal and infant mortality. The clinical characteristics in utero and in neonates have been well described. Since few cases exceeding five years of age have been reported, the phenotype is yet to be established. In the case being reported we describe oral cavity findings not documented in the literature. Copyright © 2015 Sociedad Chilena de Pediatría. Publicado por Elsevier España, S.L.U.

Rubinstein-Taybi syndrome (RSTS) is a rare autosomal dominant neurodevelopmental disorder characterized by broad thumbs and halluces. RSTS is caused by mutations in CREBBP and in EP300 genes in 50-60% and 8%, respectively. Up to now, 76 RSTS-EP300 patients have been described. We present the clinical and molecular characterization of a cohort of RSTS patients carrying EP300 mutations. Patients were selected from a cohort of 72 individuals suspected of RSTS after being negative in CREBBP study. MLPA and panel-based NGS EP300 were performed. Eight patients were found to carry EP300 mutations. Phenotypic characteristics included: intellectual disability (generally mild), postnatal growth retardation, infant feeding problems, psychomotor and language delay and typical facial dysmorphisms (microcephaly, downslanting palpebral fissures, columella below the alae nasi, and prominent nose). Broad thumbs and/or halluces were common, but angulated thumbs were only found in two patients. We identified across the gene novel mutations, including large deletion, frameshift mutations, nonsense, missense and splicing alterations, confirming de novo origin in all but one (the mother, possibly underdiagnosed, has short and broad thumbs and had learning difficulties). The clinical evaluation of our patients corroborates that clinical features in EP300 are less marked than in CREBBP patients although it is difficult to establish a genotype-phenotype correlation although. It is remarkable that these findings are observed in a RSTS-diagnosed cohort; some patients harbouring EP300 mutations could present a different phenotype. Broadening the knowledge about EP300-RSTS phenotype may contribute to improve the management of patients and the counselling to the families.

Perceptual and cognitive biases in individuals with body dysmorphic disorder symptoms.

Clerkin, Elise M; Teachman, Bethany A

2008-01-01

Given the extreme focus on perceived physical defects in body dysmorphic disorder (BDD), we expected that perceptual and cognitive biases related to physical appearance would be associated with BDD symptomology. To examine these hypotheses, participants ( N = 70) high and low in BDD symptoms completed tasks assessing visual perception and cognition. As expected, there were significant group differences in self-, but not other-, relevant cognitive biases. Perceptual bias results were mixed, with some evidence indicating that individuals high (versus low) in BDD symptoms literally see themselves in a less positive light. Further, individuals high in BDD symptoms failed to demonstrate a normative self-enhancement bias. Overall, this research points to the importance of assessing both cognitive and perceptual biases associated with BDD symptoms, and suggests that visual perception may be influenced by non-visual factors.

Body dysmorphic disorder: diagnosis and treatment.

Our society constantly sees images of athletes and models in movies and magazines and on television. These people often are presented as representing the ideals of the human body. These images can have a significant effect on people who already are predisposed to being preoccupied with their appearance, those who suffer from body dysmorphic disorder (BDD). People who have this disorder are preoccupied with certain aspects of their bodies and often seek to remedy their perceived flaws with cosmetic treatment. A general dentist may be the first health care worker who has an opportunity to intervene and assist these people in getting treatment. Patients may have unrealistic expectations for certain procedures, so assessing their psychological status is an important part of treatment planning and diagnosis. Patient expectations should be determined and the ability to provide care that meets those expectations should be discussed.

Body dysmorphic disorder (BDD) is one of the most common psychiatric conditions found in patients seeking cosmetic surgery. BDD is also a challenge for plastic surgeons because it is still an underdiagnosed mental disorder. The aims of this study were to prospectively investigate whether patients with mild to moderate BDD are suitable for rhinoplasty, and to assess BDD severity and patient satisfaction with the surgical outcome 1 year after the intervention. All women (n = 116) seeking rhinoplasty at a university hospital between September 2009 and August 2010 were recruited for the study and assessed for BDD. The final sample consisted of 31 patients aged 32 (standard deviation (SD), 10) years with mild to moderate BDD who underwent rhinoplasty. The participants were assessed preoperatively (baseline) and 1 year postoperatively with the Body Dysmorphic Disorder Examination (BDDE). Most patients (22/31, 71%) were of African descent. Socio-demographic variables and the extent of the nasal deformities had no effect on the severity of BDD symptoms and patient satisfaction with surgery outcome. At the 1-year postoperative follow-up, there was a significant decrease from baseline in BDDE scores and time spent by patients worrying about their appearance; 25 (25/31, 81%) patients experienced complete remission from BDD and 28 (28/31, 90%) were satisfied with the results of surgery. Rhinoplasty may be indicated in the treatment of female patients with mild to moderate BDD. Copyright © 2014 British Association of Plastic, Reconstructive and Aesthetic Surgeons.

The aim of the current study was to establish the prevalence of subthreshold body dysmorphic disorder (subthreshold-BDD) in a community sample of adolescents, and to compare disorder correlates in individuals with subthreshold-BDD to those with probable full-syndrome BDD (probable-BDD) and those without BDD (non-BDD). Self-report questionnaires assessing DSM-IV BDD criteria, past mental health service use, and symptoms of body dysmorphic disorder, anxiety, depression, obsessive-compulsive disorder and eating disorders, were completed by 3149 Australian high school students (mean age =14.6 years, 63.5% male). Male participants also completed measures assessing quality of life, muscularity concerns, emotional symptoms, conduct problems, hyperactivity, and peer problems. The prevalence of subthreshold-BDD was 3.4%, and probable-BDD was 1.7%. Compared to the non-BDD group, subthreshold-BDD was associated with elevated symptoms of comorbid psychopathology and greater past mental health service use, and in male-only measures, with poorer quality of life and elevated muscularity concerns. Subthreshold-BDD participants reported significantly lower mental health service use, and fewer symptoms of depression, eating disorders, and hyperactivity than probable-BDD participants, however, other comorbid symptoms did not differ significantly between these groups. These findings indicate that subthreshold-BDD is associated with substantial difficulties for adolescents in the general community. BDD screening should include subthreshold presentations, as these may be an important target for early intervention programs. Copyright © 2017 Elsevier Ireland Ltd. All rights reserved.

Body dysmorphic disorder (BDD) is defined as having a preoccupation with a perceived flaw in one's appearance, which appears slight to others and significantly interferes with a person's functioning. When undetected in septorhinoplasty patients, it will often lead to poor outcomes. We performed a prospective cohort study to determine the prevalence of BDD in our patients and whether surgical correction could be considered. We recruited 34 patients being considered for septorhinoplasty in a tertiary referral rhinology clinic and a control group of 50 from the otology clinic giving a total of 84. Participants completed the Body Dysmorphic Disorder Questionnaire (BDDQ), the sino-nasal outcome test-23 (SNOT-23) and underwent nasal inspiratory peak flow (NIPF). Those found to be at high risk for BDD were referred to a clinical psychologist. Of the septorhinoplasty patients, 11 (32%) were high risk for BDD. Following psychological assessment, 7 (63%) patients were felt to be unsuitable for surgery and were offered psychological therapy. SNOT-23 scores were significantly higher in the BDD group indicating a negative impact on quality of life. NIPF readings were not significantly different in the BDD group compared to the control group. The BDDQ is a valid tool for identifying patients at risk of BDD. A close working relationship with clinical psychology has been advantageous to help the selection process of candidates for surgery when there is a high risk of BDD. © 2016 John Wiley & Sons Ltd.

Background To alert for the diagnosis of the 22q11.2 deletion syndrome (22q11.2DS) in patients with congenital heart disease (CHD). Objective To describe the main CHDs, as well as phenotypic, metabolic and immunological findings in a series of 60 patients diagnosed with 22q11.2DS. Methods The study included 60 patients with 22q11.2DS evaluated between 2007 and 2013 (M:F=1.3, age range 14 days to 20 years and 3 months) at a pediatric reference center for primary immunodeficiencies. The diagnosis was established by detection of the 22q11.2 microdeletion using FISH (n = 18) and/or MLPA (n = 42), in association with clinical and laboratory information. Associated CHDs, progression of phenotypic facial features, hypocalcemia and immunological changes were analyzed. Results CHDs were detected in 77% of the patients and the most frequent type was tetralogy of Fallot (38.3%). Surgical correction of CHD was performed in 34 patients. Craniofacial dysmorphisms were detected in 41 patients: elongated face (60%) and/or elongated nose (53.3%), narrow palpebral fissure (50%), dysplastic, overfolded ears (48.3%), thin lips (41.6%), elongated fingers (38.3%) and short stature (36.6%). Hypocalcemia was detected in 64.2% and decreased parathyroid hormone (PTH) level in 25.9%. Decrease in total lymphocytes, CD4 and CD8 counts were present in 40%, 53.3% and 33.3%, respectively. Hypogammaglobulinemia was detected in one patient and decreased concentrations of immunoglobulin M (IgM) in two other patients. Conclusion Suspicion for 22q11.2DS should be raised in all patients with CHD associated with hypocalcemia and/or facial dysmorphisms, considering that many of these changes may evolve with age. The 22q11.2 microdeletion should be confirmed by molecular testing in all patients. PMID:25317860

In childhood, several rare genetic diseases have overlapping symptoms and signs, including those regarding growth alterations, thus the differential diagnosis is sometimes difficult. The proband, aged 3 years, was suspected to have Silver-Russel syndrome because of intrauterine growth retardation, postnatal growth retardation, typical facial dysmorphic features, macrocephaly, body asymmetry, and bilateral fifth finger clinodactyly. Other features were left atrial and ventricular enlargement and patent foramen ovale. Total X-ray skeleton showed hypoplasia of the twelfth rib bilaterally and of the coccyx, slender long bones with thick cortex, and narrow medullary channels. The genetic investigation did not confirm Silver-Russel syndrome. At the age of 5 the patient developed an additional sign: hepatomegaly. Array CGH revealed a 147 kb deletion (involving TRIM 37 and SKA2 genes) on one allele of chromosome 17, inherited from his mother. These results suggested Mulibrey nanism. The clinical features were found to fit this hypothesis. Sequencing of the TRIM 37 gene showed a single base change at a splicing locus, inherited from his father that provoked a truncated protein. The combined use of Array CGH and DNA sequencing confirmed diagnosis of Mulibrey nanism. The large deletion involving the SKA2 gene, along with the increased frequency of malignant tumours in mulibrey patients, suggests closed monitoring for cancer of our patient and his mother. Array CGH should be performed as first tier test in all infants with multiple anomalies. The clinician should reconsider the clinical features when the genetics suggests this. © 2016 Wiley Periodicals, Inc. © 2016 Wiley Periodicals, Inc.

Our aim was to systematically review the prevalence of body dysmorphic disorder (BDD) in a variety of settings. Weighted prevalence estimate and 95% confidence intervals in each study were calculated. The weighted prevalence of BDD in adults in the community was estimated to be 1.9%; in adolescents 2.2%; in student populations 3.3%; in adult psychiatric inpatients 7.4%; in adolescent psychiatric inpatients 7.4%; in adult psychiatric outpatients 5.8%; in general cosmetic surgery 13.2%; in rhinoplasty surgery 20.1%; in orthognathic surgery 11.2%; in orthodontics/cosmetic dentistry settings 5.2%; in dermatology outpatients 11.3%; in cosmetic dermatology outpatients 9.2%; and in acne dermatology clinics 11.1%. Women outnumbered men in the majority of settings but not in cosmetic or dermatological settings. BDD is common in some psychiatric and cosmetic settings but is poorly identified.

The Presentation of Body Dysmorphic Disorder in Medical Settings

PubMed Central

Phillips, Katharine A.

2006-01-01

Body dysmorphic disorder (BDD) is a relatively common psychiatric illness that often presents to mental health professionals as well as nonpsychiatric physicians. However, BDD usually goes unrecognized and undiagnosed in clinical settings. It is important to recognize and accurately diagnose BDD because this often secret illness may be debilitating. Patients with BDD typically have markedly impaired functioning, notably poor quality of life, and a high rate of suicidal ideation and suicide attempts. Thus, it is important to screen patients for BDD and avoid misdiagnosing it as another illness. Nonpsychiatric treatments (eg, dermatologic, surgical), which most patients seek and receive, appear ineffective for BDD and can be risky for physicians to provide. This article provides a clinically focused overview of BDD, including its symptoms, morbidity, case examples, nonpsychiatric (ie, cosmetic) treatment, diagnostic “do’s” and “don’ts,” and suggestions for how to persuade patients to accept appropriate psychiatric care.

2016-12-01

A high proportion of individuals with body dysmorphic disorder (BDD) undergo cosmetic treatments in an attempt to 'fix' perceived defect/s in their physical appearance. Despite the frequency with which such procedures are sought, few studies have prospectively examined the outcomes of cosmetic procedures in individuals with BDD. This article aims to critically review the literature and discuss the current debate that exists on outcomes of cosmetic treatment for individuals with BDD. An emerging literature suggests the majority of individuals with BDD have poor outcomes after cosmetic interventions; however, based on the current literature, it cannot be fully ruled out that certain individuals with mild BDD and localised appearance concerns may benefit from these interventions. Gaps in the current literature are highlighted, alongside recommendations for future research. Carefully conducted longitudinal studies with well-characterised patient populations are needed.

Body Dysmorphic, Obsessive-Compulsive, and Social Anxiety Disorder Beliefs as Predictors of In Vivo Stressor Responding.

Parsons, E Marie; Straub, Kelsey T; Smith, April R; Clerkin, Elise M

2017-06-01

This study tested the potential transdiagnostic nature of body dysmorphic disorder (BDD), obsessive-compulsive disorder (OCD), and social anxiety disorder (SAD) beliefs, in addition to testing the specificity of those beliefs, in predicting how individuals responded to symptom-specific stressors. Participants included 127 adults (75% women) with a broad range of symptom severity. Path analysis was used to evaluate whether specific maladaptive beliefs predicted distress in response to symptom-relevant stressors over and above other beliefs and baseline distress. SAD beliefs emerged as a significant predictor of distress in response to a mirror gazing (BDD-relevant), a thought (OCD-relevant), and a public speaking (SAD-relevant) task, controlling for other disorder beliefs and baseline distress. BDD beliefs were also a robust predictor of BDD stressor responding. Results suggest that social anxiety-relevant beliefs may function as a transdiagnostic risk factor that predicts in vivo symptoms across a range of problem areas.

Therapeutic strategies for patients with micropenis or penile dysmorphic disorder.

Micropenis in adults is defined as a stretched length of <7.5 cm. Many aetiologies exist, including congenital and endocrinological causes as well as pathological conditions, such as penile lichen sclerosus, trauma and genital cancer. The resulting reduction in functional penile length can lead to considerable psychosexual morbidity. Furthermore, the subset of patients with micropenis who also suffer from penile dysmorphic disorder require careful and intensive psychological counselling. Corrective surgery for micropenis can be performed in patients with realistic expectations. Total phalloplasty using radial-artery-based forearm skin flaps can offer restoration of normal penile length in selected patients. More-conservative surgical techniques to improve length or girth are limited by minimal enhancement but associated with a significantly lower rate of complications and comorbidity compared to total phalloplasty. Emerging tissue engineering techniques might represent a suitable alternative to penile replacement surgery in the future.

Selective attention to imagined facial ugliness is specific to body dysmorphic disorder.

Cognitive-behavioral models postulate that biases in selective attention are key factors contributing to susceptibility to and maintenance of body dysmorphic disorder (BDD). Visual attention in particular toward the imagined defect in appearance may be a crucial element. The present study therefore examined whether individuals with BDD showed increased visual attention to flaws in their own and in unfamiliar faces. Twenty individuals with BDD, 20 individuals with social phobia, and 20 mentally healthy individuals participated in an eye-tracking experiment. Participants were instructed to gaze at the photographs of 15 pictures of themselves and several unfamiliar faces. Only patients with BDD showed heightened selective visual attention to the imagined defect in their own face, as well to corresponding regions in other, unfamiliar faces. The results support the assumption that there is a specific attentional bias in BDD. Copyright © 2012 Elsevier Ltd. All rights reserved.

Legal and medical aspects of body dysmorphic disorder.

Nachshoni, Tali; Kotler, Moshe

2007-12-01

Body Dysmorphic Disorder (BDD), a preoccupation with an imagined defect in physical appearance has a rich clinical history, but officially appeared with diagnostic criteria only in the DSM-III-R classification system. Prevalence of BDD in plastic and cosmetic dermatology ranges between 7-15% due to the obsession with imagined imperfections. The emotional "defect" causes dissatisfaction with nonpsychiatric medical procedures, and often recourse into legal action. We present a case study of BDD developing after cosmetic surgery and debate whether this is an actual possibility and the legal consequences of this possibility. We question whether surgery was a traumatic event and its relationship to the patient's premorbid "eggshell personality". The difficulty in determining causation of psychiatric disorders for the purpose of deciding issues of compensation is discussed. A practical algorithm is offered in order to avoid litigation and to maintain the legitimate medical ideal of "first do no harm".

Whole-exome sequencing (WES) is a type of disruptive technology that has tremendous influence on human and clinical genetics research. An efficient and cost-effective method, WES is now widely used as a diagnostic tool for identifying the molecular basis of genetic syndromes that are often challenging to diagnose. Here we report a patient with a clinical diagnosis of cerebro-facio-thoracic dysplasia (CFTD; MIM#213980) in whom we identified a homozygous splice-site mutation in the transmembrane and coiled-coil domains 1 (TMCO1) gene using WES. TMCO1 mutations cause craniofacial dysmorphism, skeletal anomalies characterized by multiple malformations of the vertebrae and ribs, and intellectual disability (MIM#614132). A retrospective review revealed that clinical manifestations of both syndromes are very similar and overlap remarkably. We propose that mutations of TMCO1 are not only responsible for craniofacial dysmorphism, skeletal anomalies and mental retardation syndrome but also for CFTD.

Whole exome sequencing is a powerful tool for the analysis of genetically heterogeneous conditions. The prioritization of variants identified often focuses on nonsense, frameshift and canonical splice site mutations, and highly deleterious missense variants, although other defects can also play a role. The definition of the phenotype range and course of rare genetic conditions requires long-term clinical follow-up of patients. We report an adult female patient with severe intellectual disability, severe speech delay, epilepsy, autistic features, aggressiveness, sleep problems, broad-based clumsy gait and constipation. Whole exome sequencing identified a de novo mutation in the SYNGAP1 gene. The variant was located in the broader splice donor region of intron 10 and replaced G by A at position +5 of the splice site. The variant was predicted in silico and shown experimentally to abolish the regular splice site and to activate a cryptic donor site within exon 10, causing frameshift and premature termination. The overall clinical picture of the patient corresponded well with the characteristic SYNGAP1-associated phenotype observed in previously reported patients. However, our patient was 31 years old which contrasted with most other published SYNGAP1 cases who were much younger. Our patient had a significant growth delay and microcephaly. Both features normalised later, although the head circumference stayed only slightly above the lower limit of the norm. The patient had a delayed puberty. Her cognitive and language performance remained at the level of a one-year-old child even in adulthood and showed a slow decline. Myopathic facial features and facial dysmorphism became more pronounced with age. Although the gait of the patient was unsteady in childhood, more severe gait problems developed in her teens. While the seizures remained well-controlled, her aggressive behaviour worsened with age and required extensive medication. The finding in our patient underscores the notion that the interpretation of variants identified using whole exome sequencing should focus not only on variants in the canonical splice dinucleotides GT and AG, but also on broader splice regions. The long-term clinical follow-up of our patient contributes to the knowledge of the developmental trajectory in individuals with SYNGAP1 gene defects.

The rearrangements in the 22q11.2 chromosomal region, responsible for the 22q11.2 deletion and microduplication syndromes, are frequently associated with congenital heart disease (CHD). The present work aimed to identify the genetic basis of CHD in 87 patients from the São Miguel Island, Azores, through the detection of copy number variants (CNVs) in the 22q11.2 region. These structural variants were searched using multiplex ligation-dependent probe amplification (MLPA). In patients with CNVs, we additionally performed fluorescent in situ hybridization (FISH) for the assessment of the exact number of 22q11.2 copies among each chromosome, and array comparative genomic hybridization (array-CGH) for the determination of the exact length of CNVs. We found that four patients (4.6%; A to D) carried CNVs. Patients A and D, both affected with a ventricular septal defect, carried a de novo 2.5 Mb deletion of the 22q11.2 region, which was probably originated by inter-chromosomal (inter-chromatid) non-allelic homologous recombination (NAHR) events in the regions containing low-copy repeats (LCRs). Patient C, with an atrial septal defect, carried a de novo 2.5 Mb duplication of 22q11.2 region, which could have been probably generated during gametogenesis by NAHR or by unequal crossing-over; additionally, this patient presented a benign 288 Kb duplication, which included the TOP3B gene inherited from her healthy mother. Finally, patient B showed a 3 Mb triplication associated with dysmorphic facial features, cognitive deficit and heart defects, a clinical feature not reported in the only case described so far in the literature. The evaluation of patient B's parents revealed a 2.5 Mb duplication in her father, suggesting a paternal inheritance with an extra copy. This report allowed the identification of rare deletion and microduplication syndromes in Azorean CHD patients. Moreover, we report the second patient with a 22q11.2 triplication, and we suggest that patients with triplications of chromosome 22q11.2, although they share some characteristic features with the deletion and microduplication syndromes, present a more severe phenotype probably due to the major dosage of implicated genes.

Ring chromosome 6, r(6), is an extremely rare cytogenetic abnormality with clinical heterogeneity which arises typically de novo. The phenotypes of r(6) can be highly variable, ranging from almost normal to severe malformations and neurological defects. Up to now, only 33 cases have been reported in the literature. In this 10-year follow-up study, we report a case presenting distinctive facial features, severe developmental delay, and gray matter heterotopia with r(6) and terminal deletions of 6p25.3 (115426-384174, 268 kb) and 6q26-27 (168697778-170732033, 2.03 Mb) encompassing 2 and 15 candidate genes, respectively, which were detected using G-banding karyotyping, FISH, and chromosomal microarray analysis. We also analyzed the available information on the clinical features of the reported r(6) cases in order to provide more valuable information on genotype-phenotype correlations. To the best of our knowledge, this is the first report of gray matter heterotopia manifested in a patient with r(6) in China, and the deletions of 6p and 6q in our case are the smallest with the precise size of euchromatic material loss currently known. © 2018 S.

Nance-Horan Syndrome (NHS) or X-linked cataract-dental syndrome is a disease of unknown gene action mechanism, characterized by congenital cataract, dental anomalies, dysmorphic features and, in some cases, mental retardation. We performed linkage analysis in a Tunisian family with NHS in which affected males and obligate carrier female share a common haplotype in the Xp22.32-p11.21 region that contains the NHS gene. Direct sequencing of NHS coding exons and flanking intronic sequences allowed us to identify the first missense mutation (P551S) and a reported SNP-polymorphism (L1319F) in exon 6, a reported UTR–SNP (c.7422 C>T) and a novel one (c.8239 T>A) in exon 8. Both variations P551S and c.8239 T>A segregate with NHS phenotype in this family. Although truncations, frame-shift and copy number variants have been reported in this gene, no missense mutations have been found to segregate previously. This is the first report of a missense NHS mutation causing NHS phenotype (including cardiac defects). We hypothesize also that the non-reported UTR–SNP of the exon 8 (3′-UTR) is specific to the Tunisian population. PMID:21559051

Oculofaciocardiodental syndrome (OFCD) is an X-linked dominant disorder associated with male lethality, presenting with congenital cataract, dysmorphic face, dental abnormalities and septal heart defects. Mutations in BCOR (encoding BCL-6-interacting corepressor) cause OFCD. Here, we report on a Korean family with common features of OFCD including bilateral 2nd-3rd toe syndactyly and septal heart defects in three affected females (mother and two daughters). Through the mutation screening and copy number analysis using genomic microarray, we identified a novel heterozygous mutation, c.888delG, in the BCOR gene and two interstitial microduplications at Xp22.2-22.13 and Xp21.3 in all the three affected females. The BCOR mutation may lead to a premature stop codon (p.N297IfsX80). The duplication at Xp22.2-22.13 involved the NHS gene causative for Nance-Horan syndrome, which is an X-linked disorder showing similar clinical features with OFCD in affected males, and in carrier females with milder presentation. Considering the presence of bilateral 2nd-3rd toe syndactyly and septal heart defects, which is unique to OFCD, the mutation in BCOR is likely to be the major determinant for the phenotypes in this family.

Biliary atresia (BA) is a pediatric cholangiopathy with unknown etiology occurring in isolated and syndromic forms. Laterality defects affecting the cardiovascular and gastrointestinal systems are the most common features present in syndromic BA. Most cases are sporadic, although reports of familial cases have led to the hypothesis of genetic susceptibility in some patients. We identified a child with BA, malrotation, and interrupted inferior vena cava whose father presented with situs inversus, polysplenia, panhypopituitarism, and mildly dysmorphic facial features. Chromosomal microarray analysis demonstrated a 277kb heterozygous deletion on chromosome 20 which included a single gene, FOXA2, in the proband and her father. This deletion was confirmed to be de novo in the father. The proband and her father share a common diagnosis of heterotaxy, but they also each presented with a variety of other issues. Further genetic screening revealed that the proband carried an additional protein-altering polymorphism (rs1904589; p.His165Arg) in the NODAL gene that is not present in the father, and this variant has been shown to decrease expression of the gene. As FOXA2 can be a regulator of NODAL expression, we propose that haploinsufficiency for FOXA2 combined with a decreased expression of NODAL is the likely cause for syndromic BA in this proband.

Kenny Caffey syndrome (KCS) is a rare syndrome reported almost exclusively in Middle Eastern populations. It is characterized by severe growth retardation—short stature, dysmorphic features, episodic hypocalcaemia, hypoparathyroidism, seizures, and medullary stenosis of long bones with thickened cortices. We report a 10-year-old boy with KCS with an unusually severe respiratory and gastrointestinal system involvement—features not previously described in the literature.

Kenny Caffey syndrome (KCS) is a rare syndrome reported almost exclusively in Middle Eastern populations. It is characterized by severe growth retardation-short stature, dysmorphic features, episodic hypocalcaemia, hypoparathyroidism, seizures, and medullary stenosis of long bones with thickened cortices. We report a 10-year-old boy with KCS with an unusually severe respiratory and gastrointestinal system involvement-features not previously described in the literature. He had severe psychomotor retardation and regressed developmentally from walking unaided to sitting with support. MRI brain showed bilateral hippocampal sclerosis, marked supra-tentorial volume loss and numerous calcifications. A 12 bp deletion of exon 2 of tubulin-specific chaperone E (TBCE) gene was identified and the diagnosis of KCS was confirmed. Hypercarbia following a sleep study warranted nocturnal continuous positive airway pressure (CPAP) when aged 6. When boy aged 8, persistent hypercarbia with increasing oxygen requirement and increased frequency and severity of lower respiratory tract infections led to progressive respiratory failure. He became fully dependent on non-invasive ventilation and by 9 years he had a tracheotomy and was established on long-term ventilation. He developed retching, vomiting and diarrhea.

Geleophysic dysplasia (GD, OMIM 231050) is an autosomal recessive disorder characterised by short stature, small hands and feet, stiff joints, and thick skin. Patients often present with a progressive cardiac valvular disease which can lead to an early death. In a previous study including six GD families, we have mapped the disease gene on chromosome 9q34.2 and identified mutations in the A Disintegrin And Metalloproteinase with Thrombospondin repeats-like 2 gene (ADAMTSL2). Following this study, we have collected the samples of 30 additional GD families, including 33 patients and identified ADAMTSL2 mutations in 14/33 patients, comprising 13 novel mutations. The absence of mutation in 19 patients prompted us to compare the two groups of GD patients, namely group 1, patients with ADAMTSL2 mutations (n=20, also including the 6 patients from our previous study), and group 2, patients without ADAMTSL2 mutations (n=19). The main discriminating features were facial dysmorphism and tip-toe walking, which were almost constantly observed in group 1. No differences were found concerning heart involvement, skin thickness, recurrent respiratory and ear infections, bronchopulmonary insufficiency, laryngo-tracheal stenosis, deafness, and radiographic features. It is concluded that GD is a genetically heterogeneous condition. Ongoing studies will hopefully lead to the identification of another disease gene.

The value of the study of natural history in genetic disorders and congenital anomaly syndromes.

The study of the natural history of genetic disorders and syndromes with congenital anomalies and dysmorphic features is a challenging and often neglected area. There are many reasons to pursue this type of research but it requires special clinical skills and a considerable amount of hard work. Setting up protocols and collecting data is complex and time consuming. Frequently, helpful clues for a particular disorder come from the study of the natural history of other disorders. Older affected subjects and unique cases with unusual features are often most important in unravelling the 'normal' course of a disease or recognising the basic defect. The study of natural history from individual patients and their records is complementary to population or registry based studies because it identifies individual variations and clinical heterogeneity. The understanding of the natural history of a particular disorder is of importance both to the affected person and their family and to the physicians caring for them. It is also useful to the basic researcher trying to determine the pathogenetic mechanism causing the disorder. In many ways, clinical geneticists have learned the art of caring for patients, as well as the challenges of clinical genetics, by becoming apprentices to and studying in depth specific disease entities.

The coordinated tissue-specific regulation of gene expression is essential for the proper development of all organisms. Mutations in multiple transcriptional regulators cause a group of neurodevelopmental disorders termed "transcriptomopathies" that share core phenotypical features including growth retardation, developmental delay, intellectual disability and facial dysmorphism. Cornelia de Lange syndrome (CdLS) belongs to this class of disorders and is caused by mutations in different subunits or regulators of the cohesin complex. Herein, we report on the clinical and molecular characterization of seven patients with features overlapping with CdLS who were found to carry mutations in chromatin regulators previously associated to other neurodevelopmental disorders that are frequently considered in the differential diagnosis of CdLS. The identified mutations affect the methyltransferase-encoding genes KMT2A and SETD5 and different subunits of the SWI/SNF chromatin-remodeling complex. Complementary to this, a patient with Coffin-Siris syndrome was found to carry a missense substitution in NIPBL. Our findings indicate that mutations in a variety of chromatin-associated factors result in overlapping clinical phenotypes, underscoring the genetic heterogeneity that should be considered when assessing the clinical and molecular diagnosis of neurodevelopmental syndromes. It is clear that emerging molecular mechanisms of chromatin dysregulation are central to understanding the pathogenesis of these clinically overlapping genetic disorders.

Cytogenetic studies were initiated on a newborn female due to multiple congenital anomalies including microcephaly, clinodactyly, abnormal positioning of hands, left facial palsy, heart defect, sacral dimple, and facial dysmorphic features. Facial features were described as low set rotated ears, nystagmus, and a small, flattened nose. A structural rearrangement of the long arm of chromosome 3 was observed with a complex banding pattern. Study of parental chromosomes revealed a normal male pattern for the father, and an intrachromosomal insertion on the long arm of chromosome 3 for the mother described as 46,XX,dir ins(3)(q21q23q26.2). Further characterization of the proband`s structurally abnormalmore » chromosome 3 revealed a karyotype best described as: 46,XX,rec(3),dupq23{r_arrow}q26.2::q21{r_arrow}q23,dir ins(3)(q21q23q26.2), which is a partial duplication of both the inserted segment as well as the intervening segment between the inserted segment and the insertion site. This would appear to be the result of a three-strand double cross-over within the insertion loop. Molecular cytogenetic studies are presently underway to further elucidate chromosome structure of the proband and her mother.« less

The 17p13.1 microdeletion syndrome is a recently described genomic disorder with a core clinical phenotype of intellectual disability, poor to absent speech, dysmorphic features, and a constellation of more variable clinical features, most prominently microcephaly. We identified five subjects with copy-number variants (CNVs) on 17p13.1 for whom we performed detailed clinical and molecular studies. Breakpoint mapping and retrospective analysis of published cases refined the smallest region of overlap (SRO) for microcephaly to a genomic interval containing nine genes. Dissection of this phenotype in zebrafish embryos revealed a complex genetic architecture: dosage perturbation of four genes (ASGR1, ACADVL, DVL2, and GABARAP) impeded neurodevelopment and decreased dosage of the same loci caused a reduced mitotic index in vitro. Moreover, epistatic analyses in vivo showed that dosage perturbations of discrete gene pairings induce microcephaly. Taken together, these studies support a model in which concomitant dosage perturbation of multiple genes within the CNV drive the microcephaly and possibly other neurodevelopmental phenotypes associated with rearrangements in the 17p13.1 SRO.

Ring chromosome 2 is a rare constitutional abnormality that generally occurs de novo. About 14 cases have been described to date, but the vast majority of papers report exclusively conventional cytogenetic investigations and only two have been characterized by array-CGH. Here we describe the clinical, neuroradiological, and molecular features of a 5-year-old boy harbouring a ring chromosome 2 presenting with severe growth failure, facial and bone dysmorphisms, microcephaly, and renal malformation. Brain MR with diffusion tensor imaging revealed simplified cortical gyration, pontine hypoplasia, and abnormally thick posterior corpus callosum, suggesting an underlying axonal guidance defect. Cytogenetic investigations showed a karyotype with a ring chromosome 2 and FISH analysis with subtelomeric probes revealed the absence of signals on both arms. These results were confirmed by array-CGH showing terminal deletions on 2p25.3 (~439 kb) and 2q37.3 (~3.4 Mb). Our report describes a new patient with a ring chromosome 2 completely characterised by array-CGH providing additional information useful not only to study genotype-phenotype correlation but also to validate the role of already reported candidate genes and to suggest novel ones which could improve our understanding of the clinical features associated with ring chromosome 2.

Alagille syndrome is a multisystem disorder characterized by highly variable expressivity, most frequently caused by heterozygous JAG1 gene mutations. Classic diagnostic criteria combine the presence of bile duct paucity on liver biopsy with three of five systems affected; liver, heart, skeleton, eye and dysmorphic facies. The aim of this study was to determine the prevalence and distribution of JAG1 mutations in patients referred for routine clinical diagnostic testing. Clinical data were available for 241 patients from 135 families. The index cases were grouped according to the number of systems affected (heart, liver, skeletal, eye and facies) and the mutation frequency calculated for each group. JAG1 mutations were identified in 59/135 (44%) probands. The highest mutation detection rates were observed in patients with the most frequent presenting features of Alagille syndrome; ranging from 20% (one system) to 86% (five systems). The overall mutation pick-up rate in a clinical diagnostic setting was lower than in previous research studies. Identification of a JAG1 gene mutation is particularly useful for those patients with atypical or mild Alagille syndrome who do not meet classic diagnostic criteria as it provides a definite molecular diagnosis and allows accurate genetic counselling for the family. © 2011 John Wiley & Sons A/S.

The current study aimed to (a) determine the rates of symptoms of muscle dysmorphia (MD), body dysmorphic disorder (BDD), and eating disorder; (b) determine the relationships among symptoms of MD, BDD, and eating disorders; and (c) provide a comprehensive comparison of symptoms of MD, BDD, and eating disorders in a nonclinical population of adult male weightlifters in Australia. The participants (N = 648, mean age = 29.5 years, SD = 10.1) participated in an online survey, consisting of Muscle Appearance Satisfaction Scale, the Body Dysmorphic Disorder Questionnaire, and the Eating Attitude Test-26. Results indicated that 110 participants (17%) were at risk of having MD, 69 participants (10.6%) were at risk of having BDD, and 219 participants (33.8%) were at risk of having an eating disorder. Furthermore, 36 participants (5.6%) were found at risk of having both MD and BDD, and 60 participants (9.3%) were at risk of having both MD and an eating disorder. Significant correlations and associations were found between symptoms of MD and BDD, and symptoms of MD and eating disorders. Support was provided for the comorbidity of, and symptomatic similarities between, symptoms of MD and BDD, and symptoms of MD and eating disorders. This may reflect a shared pathogenesis between symptoms of MD, BDD, and eating disorders. Strength and conditioning professionals, exercise scientists, athletic trainers, and personal trainers should be aware that adult males who are working out with weights (i.e., free weights or machines) may be at increased risk of having MD, BDD, and eating disorders.

Body dysmorphic disorder (BDD) is one of the most common psychiatric conditions found in patients seeking cosmetic surgery, and body contouring surgery is most frequently sought by patients with BDD. To estimate the prevalence and severity of BDD symptoms in patients seeking abdominoplasty. Ninety patients of both sexes were preoperatively divided into two groups: patients with BDD symptoms (n = 51) and those without BDD symptoms (n = 39) based both on the Body Dysmorphic Disorder Examination (BDDE) and clinical assessment. Patients in the BDD group were classified as having mild to moderate or severe symptoms, according to the BDDE. Body weight and shape concerns were assessed using the Body Shape Questionnaire (BSQ). The prevalence of BDD symptoms was 57%. There were significant associations between BDD symptoms and degree of body dissatisfaction, level of preoccupation with physical appearance, and avoidance behaviors. Mild to moderate and severe symptoms of BDD were present in 41% and 59% of patients, respectively, in the BDD group. It was found that the more severe the symptoms of BDD, the higher the level of concern with body weight and shape (P < .001). Patients having distorted self-perception of body shape, or distorted comparative perception of body image were respectively 3.67 or 5.93 times more likely to show more severe symptoms of BDD than those with a more accurate perception. Candidates for abdominoplasty had a high prevalence of BDD symptoms, and body weight and shape concerns were associated with increased symptom severity. © 2016 The American Society for Aesthetic Plastic Surgery, Inc.

Penile dysmorphic disorder (PDD) is shorthand for men diagnosed with body dysmorphic disorder, in whom the size or shape of the penis is their main, if not their exclusive, preoccupation causing significant shame or handicap. There are no specific measures for identifying men with PDD compared to men who are anxious about the size of their penis but do not have PDD. Such a measure might be helpful for treatment planning, reducing unrealistic expectations, and measuring outcome after any psychological or physical intervention. Our aim was, therefore, to validate a specific measure, termed the Cosmetic Procedure Screening Scale for PDD (COPS-P). Eighty-one male participants were divided into three groups: a PDD group (n = 21), a small penis anxiety group (n = 37), and a control group (n = 23). All participants completed the COPS-P as well as standardized measures of depression, anxiety, social phobia, body image, quality of life, and erectile function. Penis size was also measured. The final COPS-P was based on nine items. The scale had good internal reliability and significant convergent validity with measures of related constructs. It discriminated between the PDD group, the small penis anxiety group, and the control group. This is the first study to develop a scale able to discriminate between those with PDD and men anxious about their size who did not have PDD. Clinicians and researchers may use the scale as part of an assessment for men presenting with anxiety about penis size and as an audit or outcome measure after any intervention for this population.

Classification of body dysmorphic disorder - what is the advantage of the new DSM-5 criteria?

PubMed

Schieber, Katharina; Kollei, Ines; de Zwaan, Martina; Martin, Alexandra

2015-03-01

In DSM-5 the diagnosis of body dysmorphic disorder (BDD) has been subjected to two important changes: Firstly, BDD has been assigned to the category of obsessive-compulsive and related disorders. Secondly, a new criterion has been defined requiring the presence of repetitive behaviors or mental acts in response to appearance concerns. The aims of this study were to report the prevalence rates of BDD based on a DSM-5 diagnosis, and to evaluate the impact of the recently introduced DSM-5 criteria for BDD by comparing the prevalence rates (DSM-5 vs. BDD-criteria (DSM-IV/DSM-5), dysmorphic concerns, and depressive symptoms, were assessed in a representative sample of the German general population (N=2129, aged 18-65years). The association between BDD case identification based on DSM-IV and DSM-5 was strong (Phi=.95, p<.001), although point prevalence of BDD according to DSM-5 was slightly lower (2.9%, n=62 vs. 3.2%, n=68). Approximately one third of the identified BDD (DSM-5) cases reported time-consuming behavioral acts in response to appearance concerns. In detail, 0.8% of the German general population fulfilled the BDD criteria and reported repetitive acts of at least one hour/day. The revised criteria of BDD in DSM-5 do not seem to have an impact on prevalence rates. However, the recently added B-criterion reflects more precisely the clinical symptoms of BDD, and may be useful for distinguishing between various severity levels related to repetitive behaviors/mental acts.

The demand for minimally invasive cosmetic procedures has continued to rise, especially in Germany, yet few studies have examined this patient population. The literature in Germany has repeatedly voiced the speculation that users of minimally invasive, skin-rejuvenating procedures displayed a higher tendency toward dysmorphic behavior patterns or, respectively, other abnormal personality traits. The aim of this study was to investigate body image, personality traits, quality of life, and socioeconomic parameters in users of botulinum toxin and/or facial fillers. One hundred forty-five females presented for botulinum toxin and/or soft tissue filler injections completed demographic and standardized psychometric questionnaires such as the World-Health-Organization Quality of Life-Short Form, Big Five Inventory-10, Body Dysmorphic Disorder Questionnaire before treatment. Patients undergoing injectable aesthetic treatments in an urban dermatology practice were women, middle-aged, highly educated, and mostly employed. Furthermore, participants showed higher quality of life, especially health-related quality of life, and a lower body mass index than controls. Concerning personality traits, our participants scored significantly higher on extraversion, agreeableness, openness to experience, and neuroticism. This study helps to better understand the psychosocial factors characterizing this patient population. Patients differ from controls by having a higher level of quality of life. No signs of body dysmorphic patterns or problematic personality traits were found. This journal requires that authors assign a level of evidence to each article.

Body Dysmorphic Disorder (BDD) is a psychiatric disorder defined as obsessive ideas about distorted physical appearance, leading to social, professional and personal dysfunction. Many of these patients seek aesthetic surgery and are generally dissatisfied with the outcome of their surgery. In the present study patients coming to the otolaryngology clinic of Thaleghani Hospital in Tehran seeking rhinoplasty were evaluated. Between October 2010 and October 2011, 130 patients seeking rhinoplasty were recruited in a cross-sectional study. These patients were consecutively interviewed in the otolaryngology clinic of Taleghani Hospital, Tehran, Iran. Questionnaires were filled containing demographic data. BDD was evaluated by a separate questionnaire. Hospital Anxiety and Depression Scale (HADS) questionnaire was filled to evaluate depression and anxiety. Data were analyzed by using SPSS software. The frequency and standard deviations were calculated. Differences between groups were evaluated by using the chi-square, and t-tests. Ninety nine (76.2%) of rhinoplasty candidates were female and thirty one (23.8%) were male. Eighty five (65.4%) were single and thirty eight (29.2%) were married while seven were divorced. About 63.8% were University students or University graduates. Mean age was 26.43±6.29 years old. 41 patients (31.5%) had BDD. Among BDD patients 12 (29.3%) had concurrent depression and 11 (26.8%) had concurrent anxiety. No statistically significant correlation was found between the presence or severity of BDD and age, gender, marital status, level of education and profession. Considering the high prevalence of Body Dysmorphic Disorder (BDD) among rhinoplasty candidates, psychiatric evaluation is advisable before surgery to avoid unnecessary operations and patient dissatisfaction.

We report a consanguineous couple that has experienced three consecutive pregnancy losses following the foetal ultrasound finding of short limbs. Post-termination examination revealed no skeletal dysplasia, but some subtle proximal limb shortening in two foetuses, and a spectrum of mildly dysmorphic features. Karyotype was normal in all three foetuses (46, XX) and comparative genomic hybridization microarray analysis detected no pathogenic copy number variants. Whole-exome sequencing and genome-wide homozygosity mapping revealed a previously reported frameshift mutation in the OBSL1 gene (c.1273insA p.T425nfsX40), consistent with a diagnosis of 3-M Syndrome 2 (OMIM #612921), which had not been anticipated from the clinical findings. Our study provides novel insight into the early clinical manifestations of this form of 3-M syndrome, and demonstrates the utility of whole exome sequencing as a tool for prenatal diagnosis in particular when there is a family history suggestive of a recurrent set of clinical symptoms.

Xq28 duplications encompassing MECP2 have been described in male patients with a severe neurodevelopmental disorder associated with hypotonia and spasticity, severe learning disability and recurrent pneumonia. We identified an Xq28 duplication in three families where several male patients had presented with intestinal pseudo-obstruction or bladder distension. The affected boys had similar dysmorphic facial appearances. Subsequently, we ascertained seven further families where the proband presented with similar features. We demonstrated duplications of the Xq28 region in five of these additional families. In addition to MECP2, these duplications encompassed several other genes already known to be associated with diseases including SLC6A8, L1CAM and Filamin A (FLNA). The two remaining families were shown to have intragenic duplications of FLNA only. We discuss which elements of the Xq28 duplication phenotype may be associated with the various genes in the duplication. We propose that duplication of FLNA may contribute to the bowel and bladder phenotype seen in these seven families. PMID:18854860

Fetus with Casamassima-Morton-Nance Syndrome and Limb-Body Wall Defect: Presentation of a Novel Association and Review of the Phenotype.

2016-01-01

In 1981, Casamassima and colleagues described an autosomal recessive syndrome of spondylocostal dysostosis associated with anal and urogenital anomalies. Here, I describe 1 new fetus who presented with limb-body wall defect as a novel association, compile 7 patients, and review the clinical phenotype of Casamassima-Morton-Nance syndrome. This appears to be the 1st Casamassima-Morton-Nance syndrome fetus with this complex malformation. In light of this manifestation, a detailed comparative phenotypic analysis of published patients revealed a heterogeneous syndrome with significant clinical variability. Accordingly, it is proposed that Casamassima-Morton-Nance syndrome should be considered in those patients with the combination of a short and asymmetric thorax with rib and vertebral anomalies and scoliosis (spondylocostal-like pattern), anal atresia, absent external genitalia, renal and urethral abnormalities (caudal dysgenesis complex), craniofacial dysmorphic features (mainly flat nose with anteverted nares, low-set/abnormal ears, and short neck), hydrops, oligohydramnios, and a poor clinical outcome.

The indications of brain single-photon emission computed tomography (SPECT) in fetal alcohol syndrome are not clearly defined, even though the condition is recognized as one of the most common causes of mental retardation. This article reports a case of a 9-year-old adopted girl with developmental delay, mildly dysmorphic facial features, and behavioral and cognitive abnormalities. Extensive investigations including genetic studies and brain magnetic resonance imaging (MRI) revealed no abnormalities, and a diagnosis of fetal alcohol syndrome was considered since official diagnostic criteria were met. A brain SPECT was requested and showed severely decreased tracer activity in the thalami, basal ganglia, and temporal lobes on both sides, the overall findings being consistent with the established diagnosis of fetal alcohol syndrome. With increasing availability of functional brain imaging, the study indications and possible ethical implications in suspected prenatal alcohol exposure or even before adoption need further consideration. In this patient, SPECT was the only test to yield positive results.

Objective: To determine the contribution of TUBB4A, recently associated with DYT4 dystonia in a pedigree with “whispering dysphonia” from Norfolk, United Kingdom, to the etiopathogenesis of primary dystonia. Methods: High-resolution melting and Sanger sequencing were used to inspect the entire coding region of TUBB4A in 575 subjects with primary laryngeal, segmental, or generalized dystonia. Results: No pathogenic variants, including the exon 1 variant (c.4C>G) identified in the DYT4 whispering dysphonia kindred, were found in this study. Conclusion: The c.4C>G DYT4 mutation appears to be private, and clinical testing for TUBB4A mutations is not justified in spasmodic dysphonia or other forms of primary dystonia. Moreover, given its allelic association with leukoencephalopathy hypomyelination with atrophy of basal ganglia and cerebellum and protean clinical manifestations (chorea, ataxia, dysarthria, intellectual disability, dysmorphic facial features, and psychiatric disorders), DYT4 should not be categorized as a primary dystonia.

Rubinstein-Taybi Syndrome (RSTS) is an autosomal dominant disorder that is classically characterized by prenatal and postnatal growth restriction, microcephaly, dysmorphic craniofacial features, broad thumbs and toes, and intellectual disability. We describe the first reported case of a pituitary macroadenoma associated with RSTS. A 39-year-old Caucasian female with a past medical history of RSTS diagnosed at age two was found to have a gadolinium-enhancing pituitary mass on magnetic resonance imaging (MRI) of the brain three years ago during workup for migraine-like headaches. Subsequent serial imaging showed radiographic evidence of growth up to 11.5 x 14.0 x 10.0 mm in size. The pituitary sellar lesion was resected through an endoscopic transnasal transsphenoidal approach and was found to be a thyrotroph adenoma. RSTS is a rare, neurodevelopmental genetic disease where most patients with disabilities survive into adulthood. The disorder is associated with an increased predisposition for development of nervous system tumors, including pituitary adenomas.

A 39-year-old Caucasian female with a past medical history of RSTS diagnosed at age two was found to have a gadolinium-enhancing pituitary mass on magnetic resonance imaging (MRI) of the brain three years ago during workup for migraine-like headaches. Subsequent serial imaging showed radiographic evidence of growth up to 11.5 x 14.0 x 10.0 mm in size. The pituitary sellar lesion was resected through an endoscopic transnasal transsphenoidal approach and was found to be a thyrotroph adenoma. RSTS is a rare, neurodevelopmental genetic disease where most patients with disabilities survive into adulthood. The disorder is associated with an increased predisposition for development of nervous system tumors, including pituitary adenomas. PMID:28503387

Temporal lobe epilepsy (TLE) is the most common form of focal epilepsy and may be associated with acquired central nervous system lesions or could be genetic. Various susceptibility genes and environmental factors are believed to be involved in the aetiology of TLE, which is considered to be a heterogeneous, polygenic, and complex disorder. Rare point mutations in LGI1, DEPDC5, and RELN as well as some copy number variations (CNVs) have been reported in families with TLE patients. We perform a genetic analysis by Array-CGH in a patient with dysmorphic features and temporal lobe epilepsy. We report a de novo duplication of the long arm of chromosome 12. We confirm that 12q22-q23.3 is a candidate locus for familial temporal lobe epilepsy with febrile seizures and highlight the role of chromosomal rearrangements in patients with epilepsy and intellectual disability.

Zellweger syndrome (ZS) is a rare autosomal recessive disorder, resulting from an impairment in peroxisome function. It is characterized by craniofacial dysmorphism and neurological abnormalities, and involves several systems, which may complicate dental and anesthesia management. The case of a 7-year-old girl diagnosed with ZS is described with emphasis on oral manifestations, oral rehabilitation under general anesthesia (GA), and home oral care. Apart from the unique features of ZS, she presented with clinodactyly, distinctive palatal vault, Class III malocclusion, missing teeth, microdontia, and delayed dental formation. Dental treatment under GA was conducted with concerns of risk of respiratory insufficiency. Oral home care by the parent and regular recall visits were essential to maintain good oral health. Children with ZS may survive into late childhood. They, however, present multiple health problems that are of special concern for not only the pediatric dentist but also the anesthesiologist. Collaboration with the medical team is essential for optimal care of these patients. ©2012 Special Care Dentistry Association and Wiley Periodicals, Inc.

Takenouchi-Kosaki syndrome (TKS) is a congenital malformation syndrome characterized by severe developmental delay, macrothrombocytopenia, camptodactyly, sensorineural hearing loss, and dysmorphic facial features. Recently, a heterozygous de novo mutation (p.Tyr64Cys) in the CDC42 gene, which encodes a key small GTP-binding protein of the Rho-subfamily, was identified in two unrelated patients with TKS. We herein report a third patient with TKS who had the same heterozygous CDC42 mutation. The phenotype of the patient was very similar to those of the two previously reported patients with TKS; however, she also demonstrated novel clinical manifestations, such as congenital hypothyroidism and immunological disturbance. Thus, despite the heterozygous mutation of CDC42 (p.Tyr64Cys) likely being a hot-spot mutation for TKS, its phenotype may be variable. Further studies and the accumulation of patients with CDC42 mutations are needed to clarify the phenotype in patients with TKS and the pathophysiological roles of the CDC42 mutation.

When to suspect a genetic syndrome.

Family physicians should be able to recognize findings on physical examination and history that suggest the presence of a genetic syndrome to aid in the diagnosis and treatment of potentially affected patients, as well as subspecialty referral. General themes that can alert family physicians to the presence of genetic conditions include dysmorphic features that are evident on physical examination; multiple anomalies in one patient; unexplained neurocognitive impairment; and a family history that is suggestive of a hereditary disease. The presence of one obvious malformation should not limit the full evaluation, because additional, subtler findings will often be important in the differential diagnosis. Taking an accurate three-generation family history is invaluable when considering a genetic syndrome. Important elements include the age and sex of family members; when family members were affected by disease or when they died; the ethnic background; and if there is consanguinity. Genetic subspecialists can assist family physicians in diagnosis, suggest additional testing and referrals if warranted, help direct medical care, and provide counseling for affected patients and their families.

The ratio of the index (2nd) finger to ring (4th) finger lengths (2D:4D) is a proxy for fetal testosterone and estradiol. Studies suggesting 2D:4D is inversely associated with autism spectrum disorder (ASD) in males were limited by lack of confounder and subgroup assessments. Studies of females are sparse. We examined associations between ASD and 2D:4D among children in the Study to Explore Early Development; we considered case subgroups and numerous potential demographic and maternal-perinatal health confounders. We observed a modest inverse association between ASD and right-hand 2D:4D in males; subgroup analyses indicated associations were limited to ASD cases with birth defects/genetic syndromes or dysmorphic features. We observed a positive association between ASD and left-hand 2D:4D in females, overall and within most case subgroups.

MEF2C haploinsufficiency caused by either microdeletion of the 5q14.3 region or mutation is responsible for severe mental retardation with stereotypic movements, epilepsy and/or cerebral malformations

Over the last few years, array-CGH has remarkably improved the ability to detect cryptic unbalanced rearrangements in patients presenting with syndromic mental retardation. Using whole genome oligonucleotide array-CGH, we detected 5q14.3 microdeletions ranging from 216 kb to 8.8 Mb in 5 unrelated patients showing phenotypic similarities, namely severe mental retardation with absent speech, hypotonia and stereotypic movements. Most of the patients presented also with facial dysmorphic features, epilepsy and/or cerebral malformations. The minimal common deleted region of these 5q14 microdeletions encompassed only MEF2C, known to act in brain as a neurogenesis effector which regulates excitatory synapse number. In a patient presenting a similar phenotype, we subsequently identified a MEF2C nonsense mutation. Taken together, these results strongly suggest that haploinsufficiency of MEF2C is responsible for severe mental retardation with stereotypic movements, seizures and/or cerebral malformations.

Norrie disease (ND) is an X-linked recessive disorder causing ocular atrophy, mental retardation, deafness, and dysmorphic features. Virtually absent monoamine oxidase (MAO) type-A and -B activity has been found in some boys with chromosome deletions. We report the coexistence of cataplexy and abnormal REM sleep organization with ND. Three related boys, referred for treatment of medically refractory atonic spells and apneas, underwent extended EEG-video-polysomnographic monitoring. They demonstrated attacks of cataplexy and inappropriate periods of REM sleep during which they were unarousable. One boy also had generalized tonic-clonic seizures. Previous testing revealed that all three have complete ND gene deletions. In all subjects, platelet MAO-B activity was absent, serum serotonin levels were markedly increased, and plasma catecholamine levels were normal. Data from the canine narcolepsy syndrome model implicate abnormal catecholaminergic and cholinergic activities in the pathogenesis of cataplexy. Our findings suggest that abnormal MAO activity or an imbalance between serotonin and other neurotransmitter levels may be involved in the pathogenesis of human cataplexy.
