The dermatoglyphics of 135 children with acute leukaemia differed significantly from those of normal controls, and examination of 174 of the patients' first degree relatives indicated that familial factors were involved. The findings suggested that within the racial group studied dermatoglyphics may partly identify a population subgroup which is at increased risk of leukaemogenesis. While these observations may not have immediate clinical application, they are likely to contribute to a greater understanding of individuals who have increased constitutional susceptibility to leukaemia.

A genetic subtype of schizophrenia has been described in 22q11 Deletion syndrome. Previous studies have described an excess of dermatoglyphic alterations in schizophrenia, such as low a–b ridge counts (ABRCs), a high frequency of ridge dissociations, and increased dermatoglyphic fluctuating asymmetry. Little is known however, about the dermatoglyphic profile of 22qDS subjects showing psychotic symptoms and its similarity to the previously reported anomalies in schizophrenia. We studied the palmar dermatoglyphics of 22 subjects with 22qDS of predominantly Caucasian origin, 15 of whom had psychotic illness, and in 84 healthy controls of similar ethnicity. We observed higher values for total ATD angle in cases than in controls (P = 0.04). In addition, there was an excess of radial figures in the hypothenar area in cases, especially in the left hand. Interestingly, greater fluctuating asymmetry, determined by the absolute difference between right and left ABRC, was observed in 22qDS subjects compared to controls (P = 0.05). However, no differences were found for ABRCs and frequency of dissociations. Despite the small sample size, the palmprints analyzed suggest the existence of an altered dermatoglyphic profile in 22qDS, involving: (i) ATD angle amplitude, (ii) presence of radial loops in the hypothenar area, and (iii) an increment of fluctuating asymmetry. The first two features are similar to those found in other genetic syndromes associated with low IQ, while high levels of fluctuating asymmetry have often been reported in schizophrenia.

Objective: To examine dermatoglyphic features to clarify implicated genetic predisposition in the etiology of multiple sclerosis (MS). Methods: The study was conducted between January and December 2013 in the Departments of Anatomy, and Neurology, Cumhuriyet University School of Medicine, Sivas, Turkey. The dermatoglyphic data of 61 patients, and a control group consisting of 62 healthy adults obtained with a digital scanner were transferred to a computer environment. The ImageJ program was used, and atd, dat, adt angles, a-b ridge count, sample types of all fingers, and ridge counts were calculated. Results: In both hands of the patients with MS, the a-b ridge count and ridge counts in all fingers increased, and the differences in these values were statistically significant. There was also a statistically significant increase in the dat angle in both hands of the MS patients. On the contrary, there was no statistically significant difference between the groups in terms of dermal ridge samples, and the most frequent sample in both groups was the ulnar loop. Conclusions: Aberrations in the distribution of dermatoglyphic samples support the genetic predisposition in MS etiology. Multiple sclerosis susceptible individuals may be determined by analyzing dermatoglyphic samples. PMID:25274586

Introduction Investigators over years have been fascinated by dermatoglyphic patterns which has led to the development of dermatoglyphics as a science with numerous applications in various fields other than being the best and most widely used method for personal identification. Aim To assess the correlation between dermatoglyphic patterns and sagittal skeletal discrepancies. Materials and Methods A total of 180 patients, aged 18-40 years, were selected from those who attended the outpatient clinic of the Deparment of Orthodontics and Dentofacial Orthopedics, Mar Baselios Dental College, Kothamangalam, Kerala, India. The fingerprints of both hands were taken by ink and stamp method after proper hand washing. The patterns of arches, loops and whorls in fingerprints were assessed. The total ridge count was also evaluated. Data was also sent to the fingerprint experts for expert evaluation. The sagittal jaw relation was determined from the patient’s lateral cephalogram. The collected data was then statistically analyzed using Chi-square tests, ANOVA and Post-hoc tests and a Multinomial regression prediction was also done. Results A significant association was observed between the dermatoglyphic pattern exhibited by eight fingers and the sagittal skeletal discrepancies (p<0.05). An increased distribution of whorl pattern was observed in the skeletal Class II with maxillary excess group and skeletal Class II with mandibular deficiency group while an increased distribution of loop pattern was seen in the skeletal Class III with mandibular excess group and skeletal Class III with maxillary deficiency group. Higher mean of total ridge count was also seen in the groups of skeletal Class II with maxillary excess and skeletal Class II with mandibular deficiency. Multinomial regression predicting skeletal pattern with respect to the fingerprint pattern showed that the left thumb impression fits the best model for predicting the skeletal pattern. Conclusion There was a significant association between dermatoglyphic patterns and sagittal skeletal discrepancies. Dermatoglyphics could serve as a cost effective screening tool of these craniofacial problems. PMID:28511506

Dermatoglyphic prints were collected from 800 inhabitants of Dukagjin valley in Kosovo. The sample consisted of two ethnically different sub-populations who refer themselves as Albanians (N = 400) and Turks (N = 400). Qualitative analysis of prints concerned the frequency of the patterns on fingers (arch, ulnar and radial loop, whorl, accidental whorl) and on palms (Thenar and I, II, III, and IV interdigital area and the hypothenar, main line index, and the axial "t" triradius position). As was expected due to previous study of quantitative dermatoglyphic traits, in the same population the Alba-nians and Turks showed to be significantly different in most explored qualitative dermatoglyphic variables. Found differences indicated that the reproductive isolation between the Albanian and Turkish population in Kosovo is substantial, despite the fact that those two ethnic sub-populations live in the close vicinity through several centuries.

This article was designed to consider the congenital age-specific features of palm dermatoglyphics in the adults subjects (including the type of the papillary patterns, axial tri-radii, the termini of palmar main lines, the rudiments of palmar lines, the dermatoglyphic ridge count between the stable anatomical structures). The objective of the study was to look for the new diagnostic markers of the biological age. It included the identification of the palm prints obtained from 180 Caucasoid men and 120 women at the age varying from 16 to 80 years. The results of the mathematical and statistical analysis provided the basis for drawing up the list of 18 attributes of palm dermatoglyphics significantly (p<0.05) differing in the frequency of occurrence between the representatives of individual age groups. The methods are proposed allowing to use these findings for the expert evaluation of the age of unknown subjects.

Dermatoglyphics in childhood leukemia

The dermatoglyphics of 54 leukemic children do not differ significantly from those of 25 mothers and 592 unrelated controls with respect to frequency of digital pattern types, position of axial triradius, or type of palmar flexion creases. These findings do not support the hypothesis that children with leukemia have an increased frequency of unusual dermal patterns, but suggest that the dermatoglyphics of leukemic children are not distinctive and therefore have no practical value in the diagnosis of childhood leukemia. Whatever factors are responsible for the development of leukemia in children, these factors do not appear regularly to affect the differentiation of the dermal ridges. PMID:5112119

Background: Oral squamous cell carcinoma (SCC) is one name that causes panic and holds an undeserved high ranking as a killer. Another important condition which has become a major public health issue in South East Asia is oral submucous fibrosis (OSF). Not all the people using tobacco suffer from these diseases. Genetic predisposition might explain such an individual variability that can be predicted by using various cytogenetic markers. However, these studies are far more costly and complicated. So, dermatoglyphics may be of immense clinical significance to segregate those individuals who are at an increased risk for developing these diseases. Aim: The present study was conducted to analyze the palmar dermatoglyphics in SCC and OSF and find a dermatoglyphic marker, if any. Study Design: Cross sectional study. Materials and Methods: 120 individuals were divided into four groups based upon their habits of tobacco/areca nut usage and presence of OSF/SCC. Dermatoglyphic patterns were recorded using standard ink method. Various patterns were analysed statistically in the four groups. Results and Conclusion: In SCC, there was an increase in frequency of arch and ulnar loop patterns on fingertips, decrease in frequency of simple whorl patterns on fingertips, decrease in frequency of palmar accessory triradii on right and left hands. Significant findings in OSF included an increase in frequency of arch and ulnar loop pattern, decrease in frequency of simple whorl patterns on fingertips, decrease in atd angle on right hand, decrease in frequency of palmar accessory triradii on right hand. The results revealed that the field of dermatoglyphics holds promising results for determining the genetic susceptibility of individuals to develop SCC and OSF. PMID:24403787

Milia are common, small, keratin-containing cysts frequently seen in all age groups. They may arise spontaneously or develop after a variety of stimuli. They can be found alone or as part of syndromes. We present a female neonate born not only with profuse facial milia, but also with acral bullae and absent dermatoglyphics. Similar features were seen in several members of her family. These findings correspond to the syndrome known as Basan's syndrome, a rare autosomal-dominant inherited dermatosis characterized by profuse congenital milia, transient neonatal acral bullae, and absence of dermatoglyphics. © 2011 Wiley Periodicals, Inc.

Dermatoglyphic patterns, which are regularly used in judicial and legal investigations, can be valuable in the diagnosis of many diseases associated with genetic disorders. Dental caries although of infectious origin, may have a genetic predisposition. Hence, we evaluated the correlation between dental caries and dermatoglyphic patterns among subjects with and without dental caries and evaluated its association with environmental factors such as salivary pH. Totally, 76 female students within the age group of 18-23 years were clinically examined, and their decayed, missing, filled teeth (DMFT) score and oral hygiene index-simplified were recorded. Based on their DMFT score, they were divided into following three groups; group I (n = 16, DMFT score = 0), group II (n = 30, DMFT score <5), and group III (n = 30, DMFT score ≥5). Their fingerprint patterns and salivary pH were recorded and analyzed using descriptive statistics. Dermatoglyphic pattern distribution in caries-free group showed more ulnar loops than high caries group (group III) while high caries group showed more whorl patterns. Presence of whorl with double loop, whorl within a loop was associated with high DMFT score. The total finger ridge count was lower in caries group. The mean salivary pH was higher in caries-free group than high caries group. Thus, we conclude that dermatoglyphic patterns may be potential diagnostic tool for detecting patients prone to develop dental caries.

The present study is carried out to evaluate the risk of giving birth to children with Down syndrome in a family with Robertsonian translocation 14q;21q, and to find the dermatoglyphic changes present in carriers of this translocation. Cytogenetics diagnosis has been made according to Moorhead and Seabright method, while the analysis of prints (dermatoglyphics analysis) was made with the Cummins and Midlo method. Cytogenetic diagnosis has been made in a couple who suffered the spontaneous miscarriages and children with Down syndrome. Robertsonian translocation between chromosomes 14 and 21 (45, XX, der (14; 21) (q10; q10)) was found in a female partner who had four pregnancies, in two of which was found fetus karyotype with trisomy in chromosome 21 and pregnancies were terminated. The outcome of fourth pregnancy was twin birth, one of them with normal karyotype and another with Down syndrome due to Robertsonian translocation inherited by mother side. Specific dermatoglyphics traits are found in the child carrying Down syndrome, whereas several traits of dermatoglyphics characteristic of Down syndrome have been displayed among the silent carriers of Robertsonian translocation 14q;21q. Robertsonian translocation found in female partner was the cause of spontaneous miscarriages, of giving birth to a child with Down syndrome, and of trisomy of chromosome 21 due to translocation in two pregnancies.

A close correlation between asthma and palm dermatoglyphic patterns has been observed in previous studies, but the underlying genetic mechanisms have not been investigated. A disintegrin and metalloprotein-33 (ADAM33) polymorphisms are important in the development of asthma and other atopic diseases. To investigate the underlying mechanisms of the association between asthma and distinctive palm dermatoglyphic patterns, thirteen ADAM33 single-nucleotide polymorphisms (SNPs) were analyzed for the association between asthma and palm dermatoglyphic patterns in a population of 400 asthmatic patients and 200 healthy controls. Based on the results, five SNPs, rs44707 (codominant model, P=0.031; log-additive model, P=0.0084), rs2787094 (overdominant model, P=0.049), rs678881 (codominant model, P=0.028; overdominant model, P=0.0083), rs677044 (codominant model, P=0.013; log-additive model, P=0.0033) and rs512625 (dominant model, P=0.033), were associated with asthma in this population. Two SNPs, rs44707 (dominant model, P=0.042) and rs2787094 (codominant model, P=0.014; recessive model, P=0.0038), were observed in the asthma patients with the distinctive palm pattern. As rs44707 and rs2787094 are associated with asthma and a distinctive palm pattern, the data suggest that ADAM33 polymorphisms are correlated with asthma and may be the underlying genetic basis of the association between asthma and palm dermatoglyphic patterns.

2013-01-01

Background The purpose of this study was to evaluate gender-wise diversity of digital dermatoglyphic traits in a sample of Sinhalese people in Sri Lanka. Findings Four thousand and thirty-four digital prints of 434 Sinhalese individuals (217 males and 217 females) were examined for their digital dermatoglyphic pattern distribution. The mean age for the entire group was 23.66 years (standard deviation = 4.93 years). The loop pattern is observed more frequently (n = 2,592, 59.72%) compared to whorl (n = 1,542, 35.53%) and arch (n = 206, 4.75%) in the Sinhalese population. Females (n = 1,274, 58.71%) have a more ulnar loop pattern than males (n = 1,231, 56.73%). The plain whorl pattern is observed more frequently in males (n = 560, 25.81%) compared to females (n = 514, 23.69%).The double loop pattern is observed more frequently on the right and left thumb (digit 1) of both males and females. Pattern intensity index, Dankmeijer index and Furuhata index are higher in males. Conclusions Ulnar loop is the most frequently occurring digital dermatoglyphic pattern among the Sinhalese. All pattern indices are higher in males. To some extent, dermatoglyphic patterns of Sinhalese are similar to North Indians and other Caucasoid populations. Further studies with larger sample sizes are recommended to confirm our findings. PMID:24377367

Bener, A

1979-01-01

In the present paper, 539 Polish families and 999 individuals (515 males and 484 females) were analysed to determine whether asymmetry of dermatoglyphic patter elements on the fingertips of ulnar and radial loops in genetically controlled. And we enquire whether the body is bilaterally asymmetrical. We have found the asymmetry between right and left hand fingertips for ulnar and radial loops, for each digit and between the two sexes. The differences between the sexes is small. The bimanual difference in dermatoglyphic pattern elements between hands, right minus left, has been used as a measure of asymmetry. The mean and variance difference for males is not significantly different from the mean and variance for females. An investigation was also made of correlations between relatives for bimanual differences, right minus left. We may conclude from these results that the asymmetry of dermatoglphic pattern elements on fingertips of ulnar and radial loops has little hereditary component. Finally, the results of this work show that the dermatoglyphic pattern elements on fingertips of ulnar and radial loops on each side of the body are inherited.

Analysis of the quantitative dermatoglyphics of the digito-palmar complex in patients with multiple sclerosis.

Recent studies on the etiopathogenesis of multiple sclerosis (MS) all point out that there is a polygenetical predisposition for this illness. The so called "MS Trait" determines the reactivity of the immunological system upon ecological factors. The development of the glyphological science and the study of the characteristics of the digito-palmar dermatoglyphic complex (for which it was established that they are polygenetically determined characteristics) all enable a better insight into the genetic development during early embriogenesis. The aim of this study was to estimate certain differences in the dermatoglyphics of digito-palmar complexes between the group with multiple sclerosis and the comparable, phenotypically healthy groups of both sexes. This study is based on the analysis of 18 quantitative characteristics of the digito-palmar complex in 125 patients with multiple sclerosis (41 males and 84 females) in comparison to a group of 400 phenotypically healthy patients (200 males and 200 females). The conducted analysis pointed towards a statistically significant decrease of the number of digital and palmar ridges, as well as with lower values of atd angles in a group of MS patients of both sexes. The main discriminators were the characteristic palmar dermatoglyphics with the possibility that the discriminate analysis classifies over 80% of the examinees which exceeds the statistical significance. The results of this study suggest a possible discrimination of patients with MS and the phenotypically health population through the analysis of the dermatoglyphic status, and therefore the possibility that multiple sclerosis is genetically predisposed disease.

Introduction Dermatoglyphics is one of the important diagnostic tools used in the recent days for identification of an individual. Dermatoglyphics is the study of type of patterns present on digits, palms and foot. The mesiodistal diameter of the tooth is an important factor which reveals the tooth-bone discrepancy. Deciduous second molar and permanent first molar exhibit least degree of variation. Both the dermal ridges and the enamel layer of the tooth originate from ectodermal layer and during the same period of intrauterine life. Aim To determine and compare the dermatoglyphics with the mesiodistal width of the deciduous second molar and permanent first molar. Materials and Methods A sample of 120 child ranaged between 6-12 years were included in the study whose digital and palmer traits were recorded using ink method and the mesiodistal widths of the deciduous second molar and permanent first molar were recorded using a vernier caliper. The data was subjected to statistical analysis using unpaired t test. Results The ‘ATD’ angle was found in the range of 40°-50°. The loop patterns were more common followed by whorls and arch patterns. Girls expressed a greater mesiodistal diameter of deciduous second molar than boys. No significant correlation was found in between the dermatoglyphics and tooth size. Conclusion There was no significant correlation between the finger print patterns, ‘ATD’ angle and the mesiodistal diameter of the deciduous second molar and the permanent first molar. PMID:28969275

Background Breast cancer is one of the most extensively studied cancers and its genetic basis is well established. Dermatoglyphic traits are formed under genetic control early in development but may be affected by environmental factors during first trimester of pregnancy. They however do not change significantly thereafter, thus maintaining stability not greatly affected by age. These patterns may represent the genetic make up of an individual and therefore his/her predisposition to certain diseases. Patterns of dermatoglyphics have been studied in various congenital disorders like Down's syndrome and Kleinfelter syndrome. The prints can thus represent a non-invasive anatomical marker of breast cancer risk and thus facilitate early detection and treatment. Methods The study was conducted on 60 histo-pathologically confirmed breast cancer patients and their digital dermatoglyphic patterns were studied to assess their association with the type and onset of breast cancer. Simultaneously 60 age-matched controls were also selected that had no self or familial history of a diagnosed breast cancer and the observations were recorded. The differences of qualitative (dermatoglyphic patterns) data were tested for their significance using the chi-square test, and for quantitative (ridge counts and pattern intensity index) data using the t- test. Results It was observed that six or more whorls in the finger print pattern were statistically significant among the cancer patients as compared to controls. It was also seen that whorls in the right ring finger and right little finger were found increased among the cases as compared to controls. The differences between mean pattern intensity index of cases and controls were found to be statistically significant. Conclusion The dermatoglyphic patterns may be utilized effectively to study the genetic basis of breast cancer and may also serve as a screening tool in the high-risk population. In a developing country like India it might prove to be an anatomical, non-invasive, inexpensive and effective tool for screening and studying the patterns in the high-risk population. PMID:17397524

Dermatoglyphics is an extremely useful tool as a preliminary investigation method for diagnosing suspected genetic disorders. Caries being a multifactorial disease with the influence of genetic pattern, early identification of caries risk children with dermatoglyphics can help in using effective and efficient caries preventive measures. The study was undertaken to record and know the frequency of occurrence of fingerprint patterns among children with caries and in children without caries. A total of 400 schoolchildren in the age group of 5 to 12 years were selected from a private school, Warangal, Telangana, India. Of 400 schoolchildren, 200 children were with caries group and 200 children were in caries-free group. Children with dental caries in five or more teeth based on the decayed, missing, filled teeth index performed were considered as study group, and the control group was normal healthy children without any dental caries. The fingerprints of each child were recorded using stamp pad method, and type of dermatoglyphic pattern of each digit was recorded based on Cummins and Midlo method. Data obtained were put for statistical analysis; p < 0.001 was considered statistically significant. Although the frequency of whorl pattern was more prevalent in caries group, it was statistically significant on the left hand third digit of females and on the right hand third digit and the left hand fourth digit of males. Fingerprints of female caries-free group showed maximum of ulnar loop and males showed maximum of arches. There was a decrease in total ridge count in caries group, especially in males. Dermatoglyphics could be an appropriate method to explore the possibility of a noninvasive and an early predictor for dental caries. Dermatoglyphics has a future role in identifying people with or at increased risk for dental caries so that risk reduction measures or earlier therapy may be instituted.

Quantitative Fluctuating (FA) and Directional asymmetry (DA) of dermatoglyphics on digito-palmar complex were analyzed in a group of 111 patients (males: 61, females: 50) with schizophrenia (SZ), and compared to an ethnically matched phenotypically healthy control (males: 60, females: 60) through MANOVA, ANOVA and canonical Discriminant analyses. With few exceptions, asymmetries are higher among patients, and this is more prominent in FA than DA. Statistically significant differences were observed between patient and control groups, especially in males. In both sexes, FA of combined dermatoglyphic traits (e.g. total finger ridge count, total palmar pattern ridge count) are found to be a strong discriminator between the two groups with a correct classification of over 83% probability.

Autism is a neurodevelopmental disorder originating from early childhood; nevertheless, its diagnosis is in older ages. In addition to heredity, environmental factors are also of great significance in the etiology of the disease. Dermatoglyphic patterns, albeit varied, remain stable for a lifetime and yield a large number of patterns upon examination. Studies have shown a significant association between dermatoglyphics and some diseases, especially genetic ones. We compared fingerprints between patients with autism and normal individuals in a Fars population living in Khorasan-Razavi Province, Iran, in 2015. The right and left hand fingerprints of 104 autistic individuals (case group; age range=5–15 y) were collected using a fingerprint scanner. The same process was performed for 102 healthy individuals, in the age range of 6 to 25 years. All dermatoglyphic patterns and ridge counts were determined. The data were analyzed using the Mann–Whitney nonparametric test and binomial distribution. There was a significant difference in the distribution of the dermatoglyphic patterns on the right and left thumbs and the index fingers between the case and control groups (P<0.05). The patients had a significantly higher count of loops on their right and left thumbs and their index fingers. A significant decrease in ridge counts for the right and left thumbs and the index fingers was observed in the patients compared to the controls. The results suggested that the patterns were associated with the risk of autism. The patterns may be drawn upon as biometric parameters in the screening of children with autism. PMID:28761206

Palmar and finger dermatoglyphics are formed between the 10th and the 17th weeks of gestation and their morphology can be influenced by genetic or environmental factors, interfering with normal intrauterine development. As both the skin and the brain develop from the same embryonal ectoderm, dermatoglyphic alterations may be informative for early abnormal neurodevelopmental processes in the brain. We investigated whether dermatoglyphic alterations are related to structural brain abnormalities in bipolar disorder and to what extent they are of a genetic and of an environmental origin. Dermatoglyphics and volumetric data from structural MRI were obtained in 53 twin pairs concordant or discordant for bipolar disorder and 51 healthy matched control twin pairs. Structural equation modeling was used. Bipolar disorder was significantly positively associated with palmar a-b ridge count (ABRC), indicating higher ABRC in bipolar patients (rph=.17 (CI .04-.30)). Common genes appear to be involved because the genetic correlation with ABRC was significant (rph-A=.21 (CI .05-.36). Irrespective of disease, ABRC showed a genetically mediated association with brain volume, indicated by a significant genetic correlation rph-A of respectively -.36 (CI -.52 to -.22) for total brain, -.34 (CI -.51 to -.16) total cortical volume, -.27 (CI -.43 to -.08) cortical gray matter and -.23 (CI -.41 to -.04) cortical white matter. In conclusion, a genetically determined abnormal development of the foetal ectoderm between the 10th and 15th week of gestation appears related to smaller brain volumes in (subjects at risk for) bipolar disorder.

Karmakar, Bibha; Malkin, Ida; Kobyliansky, Eugene

2013-06-01

Dermatoglyphic asymmetry and diversity traits from a large number of twins (MZ and DZ) were analyzed based on principal factors to evaluate genetic effects and common familial environmental influences on twin data by the use of maximum likelihood-based Variance decomposition analysis. Sample consists of monozygotic (MZ) twins of two sexes (102 male pairs and 138 female pairs) and 120 pairs of dizygotic (DZ) female twins. All asymmetry (DA and FA) and diversity of dermatoglyphic traits were clearly separated into factors. These are perfectly corroborated with the earlier studies in different ethnic populations, which indicate a common biological validity perhaps exists of the underlying component structures of dermatoglyphic characters. Our heritability result in twins clearly showed that DA_F2 is inherited mostly in dominant type (28.0%) and FA_F1 is additive (60.7%), but no significant difference in sexes was observed for these factors. Inheritance is also very prominent in diversity Factor 1, which is exactly corroborated with our previous findings. The present results are similar with the earlier results of finger ridge count diversity in twin data, which suggested that finger ridge count diversity is under genetic control.

2013-01-01

Background The relationship between handedness and digital dermatoglyphic patterns has never been investigated in the Sinhalese population. The goal of this study is to establish the above mentioned relationship, which would positively aid personal identification.  Findings One hundred forty Sinhalese students (70 right-handed and 70 left-handed) were studied for their digital dermatoglyphic pattern distribution. The results show that a statistically significant correlation exists for; digit 5 (Ulnar loop; P= 0.0449 and radial loop; P= 0.0248 by Fisher’s exact test) of the right hand in female, digit 1 (radial loop; P=0.0248 by Fisher’s exact test) and digit 2 (Ulnar loop; P=0.0306) of the left hand in females, digit 3 (Ulnar loop; P= 0.0486 and whorl; P= 0.0356 by Fisher’s exact test) and digit 4 (Ulnar loop; P= 0.0449 and whorl; P= 0.0301 by Fisher’s exact test) of the right hand in males, digit 4 (whorl; P=0.0160 by Fisher’s exact test) of the left hand in males. Conclusions  Statistically significant differences in handedness and digital dermatoglyphic patterns were evident among Sinhalese people. Further study with a larger sample size is recommended.

669 young men and women aged 16-23 years were examined using a program including the measurements of 40 body, head and face parameters, fingerprinting and determination of personal psychological characteristics. On the basis of the study of the correlations between the different groups of characteristics, the evidence was obtained that supports the concept of a relative autonomy of the morpho-functional systems as an essential condition for the integrity of the organism as a whole. The coefficients of canonical correlation were calculated between the somatic and dermatoglyphic features (R=0.3), somatic sizes and psychological personality characteristics (R=0.4), psychological characteristics and the dermatoglyphic indices (R=0.4). An original model is suggested that describes the correlations of somatic, dermatoglyphic and psychological features in the structure of general human constitution on the basis of statistically significant canonical correlations (revealed by the author) and that takes in consideration the degree of the influence of genetic and social-economic complex of factors (on the basis of the literature data) on the development and formation of the investigated systems of characteristics.

Quantitative palmar dermatoglyphics and the assessment of population affinities: data from marine fishermen of Puri, India.

Reddy, B M; Chopra, V P; Karmakar, B; Malhotra, K C

1988-09-01

Variation in quantitative dermatoglyphics among three endogamous groups of marine fishermen of Puri Coast, India, is greater for the palmar variables than for the fingers. This is the case in both the sexes. The pattern of population affinities, however, differs for the males and females. In order to evaluate the importance of palmar variables in population studies, the results in males are compared with those of finger variables and anthropometrics. There is no significant heterogeneity between the groups for finger variables. Although significant intergroup variability is observed in the palmar and anthropometric traits, the two sets of results are not in the same direction. Palmar dermatoglyphic relationships reflect the caste affiliations, while the anthropometric are in line with geographic proximity.

Studies were carried out on the dermatoglyphics (skin ridge marks) on the hands of children with Williams syndrome; this is an inherited disease with cardiovascular pathology and a characteristic facial phenotype ("elf" facies), along with specific mental and cognitive disturbances. The results suggest a characteristic dermatoglyphic type with the presence of complex whorls on the fingers and a clear predominance of marks of greater complexity on the left hand; this is a very rare trait in normal people and in those with other inherited nervous system disorders. The features of the dermatoglyphic pattern serve as a characteristic marker of a genetically determined state of the human central nervous system, and suggests directions for neurophysiological studies of children with Williams syndrome as a unique model for analysis of higher nervous function in humans.

Dermatoglyphs in congenital heart disease.

David, T J

1981-01-01

The palmar dermatoglyphs of 800 patients with anatomically proven congenital heart disease were compared with prints from 1000 controls. A review of the previous studies revealed major technical deficiencies, and the present study failed to confirm most of the previously reported positive findings. An overall increase in the incidence of hypothenar patterns was found, probably explaining the previous suggestion of increased atd angle in congenital heart disease. A large number of statistical comparisons inevitably produced a few 'significant' results, most of which were inconsistent in various ways. Two percent of cases were found to have rare epidermal ridge malformation, ridge dissociation. The nature of the relationship between this and congenital heart disease is obscure. Claims that there are diagnostically useful dermatoglyphic changes in congenital heart disease can be disregarded. PMID:7328614

Association of Dermatoglyphic Peculiarities with Dental Caries in Preschool Children of Lucknow, India

ABSTRACT Background: Dermatoglyphics refers to study of the intricate dermal ridge configurations on the skin covering the palmar and plantar surfaces of hand and feet. The basis of considering dermatoglyphic patterns as genetic marker for dental caries is that the epithelium of finger buds as well as enamel has ectodermal origin, and both develop at the same time of intrauterine life. Aim: To assess the relationship between fingerprint patterns and dental caries among preschool children of Lucknow city. Study design: This study was of cross-sectional design. Materials and methods: The study group comprised 512 preschool children 2-6 years of age. The prevalence of caries was recorded using "Dentition status and treatment needs" (WHO basic oral health assessment form, 1997). They were divided into three groups as follows: Group I (dmft score = 0-2), group II (dmft score = 3-4) and group III (dmft score ≥5). The handprints of each child were taken using a stamp pad. The fingertip patterns were analyzed according to the classical method and were classified according to the topological method. The frequency of occurrence of type of dermatoglyphic pattern on fingertip of each digit was noted. Statistics: Chi-square test was used to test the significant difference in proportions. Means were compared using Student’s t-test and analysis of variance (ANOVA) or F-test. Results: Subjects belonging to groups II and III showed maximum occurrence of whorl pattern on all digits. Group I subjects had maximum occurrence of arch pattern. All the variables had statistically significant value, with a degree of divergence of specific dermatoglyphic patterns among all three groups. Conclusion: The dental caries susceptibility of an individual increased with incidence of whorl pattern and it decreased with incidence of arch pattern.

Dermatoglyphics in kidney diseases: a review.

Wijerathne, Buddhika T B; Meier, Robert J; Salgado, Sujatha S; Agampodi, Suneth B

2016-01-01

Kidney diseases are becoming a major cause of global burden with high mortality and morbidity. The origins of most kidney diseases are known, but for some the exact aetiology is not yet understood. Dermatoglyphics is the scientific study of epidermal ridge patterns and it has been used as a non-invasive diagnostic tool to detect or predict different medical conditions that have foetal origin. However, there have been a limited number of studies that have evaluated a dermatoglyphic relationship in different kidney diseases. The aim of this review was to systematically identify, review and appraise available literature that evaluated an association of different dermatoglyphic variables with kidney diseases. This review is reported according to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses checklist. The PubMed(®) (Medline), POPLINE, Cochrane Library and Trip Database and grey literature sources such as OpenGrey, Google Scholar, and Google were searched to earliest date to 17 April 2014. Of the 36 relevant publications, 15 were included in the review. Of these studies, there are five case reports, seven case series and three comparative studies. Possible association of dermatoglyphics with Wilms tumor (WT) had been evaluated in two comparative studies and one case series that found fewer whorls and a lower mean total ridge count (TRC). Another study evaluated adult polycystic kidney disease (APCD) type III that revealed lower TRC means in all cases. All other case series and case reports describe dermatoglyphics in various kidney disease such as acro-renal-ocular syndrome, potter syndrome, kabuki makeup syndrome, neurofaciodigitorenal syndrome, syndactyly type V, ring chromosome 13 syndrome, trisomy 13 syndrome and sirenomelia. It is evident that whorl pattern frequency and TRC have been used widely to investigate the uncertainty related to the origin of several kidney diseases such as WT and APCD type III. However, small sample sizes, possibly methodological issues, and discrepancy in the make up between cases and control groups limits interpretation of any significant findings. Future studies with proper protocol, adequate cases, and control groups may provide stronger evidence to resolve uncertainty related to the aetiology of kidney diseases.

The possible association between finger dermatoglyphic patterns and altitude and surname distribution was analyzed in a sample of adult males from the province of Jujuy, Argentina. We also investigated the biological affinity of this population with other South American natives and admixed populations. Fingerprints were obtained from 996 healthy men, aged 18-20 years, from the highlands (HL: 2500m, Puna and Quebrada) and lowlands (LL: Valle and Selvas). Surnames were classified into native/autochthonous (A) or foreign (F), resulting in three surname classes: FF, when both paternal and maternal surnames were of foreign origin; FA, when one surname was foreign and the other was native; and AA, when both surnames were native. Frequencies of finger dermatoglyphic patterns - arches (A), radial loops (RL), ulnar loops (UL), and whorls (W) - were determined for each digit in relation to geographic location, altitude, and surname origin, resulting in the following categories: HL-FF, HL-FA, HL-AA, LL-FF, LL-FA, and LL-AA. The statistical analyses showed that UL and RL were more common in individuals of HL origin, whereas W and A were more frequent in the LL males (p<0.05). Significant associations were observed between finger dermatoglyphic patterns and surname origin when geographic altitude was considered. In the HL group, UL was associated with AA and FA; in the LL group, the presence of A was associated with FF and FA. The distribution of dermatoglyphic patterns shows that the population of Jujuy belongs to the Andean gene pool and that it has undergone differential levels of admixture related to altitude.

The neurodevelopmental hypothesis of schizophrenia suggests that adverse genetic loading in conjunction with environmental factors early in fetal life causes a disruption of neural development, decades before the symptomatic manifestation of the disease. Neurocognitive deficits have been observed early on the course of schizophrenia, and their association with an early developmental brain lesion has been postulated. Dermatoglyphics have been analyzed in schizophrenia as markers of prenatal brain injury because of their early fetal ontogenesis and susceptibility to the same environmental factors that can also affect cerebral development. The aim of our study was to conduct a comparative examination of neurocognitive functions and dermatoglyphic variables in 89 sibling pairs discordant for schizophrenia spectrum disorders. Therefore, we investigated the association between these two markers to explore the prenatal origin of cognitive deficits in schizophrenia. The affected siblings were significantly impaired on all the cognitive variables assessed (Wisconsin Card Sorting Test, Trail Making Test and Continuous Performance Test) and had a greater number of dermatoglyphic anomalies. These results suggest the influence of intrauterine environmental factors in the siblings affected with schizophrenia. However, we did not detect a significant association between these two vulnerability markers in the schizophrenic patients, suggesting the role of genetic or late environmental factors in the origin of the neurocognitive deficits found in these patients.

[The point-digital interpretation and the choice of the dermatoglyphic patterns on human fingers for diagnostics of consanguineous relationship].

Zvyagin, V N; Rakitin, V A; Fomina, E E

The objective of the present study was the development of the point-digital model for the scaless interpretation of the dermatoglyphic papillary patterns on human fingers that would allow to comprehensively describe, in digital terms, the main characteristics of the traits and perform the quantitative assessment of the frequency of their inheritance. A specially developed computer program, D.glyphic. 7-14 was used to mark the dermatoglyphic patterns on the fingerprints obtained from 30 familial triplets (father + mother + child).The values of all the studied traits for kinship diagnostics were found by calculating the ratios of the sums of differences between the traits in the parent-parent pairs to those in the respective parent-child pairs. The algorithms for the point marking of the traits and reading out the digital information about them have been developed. The traditional dermatoglyphic patterns were selected and the novel ones applied for the use in the framework of the point-digital model for the interpretation of the for diagnostics of consanguineous relationship. The present experimental study has demonstrated the high level of inheritance of the selected traits and the possibility to develop the algorithms and computation techniques for the calculation of consanguineous relationship coefficients based on these traits.

Describe the characteristics of body composition, somatotype, basic physical qualities, dermatoglyphics and bone age regarding sexual maturation stages of boys. A transversal study was carried out in 136 boys, between 10 and 14 years of age. Clinical assessment, physical examination and radiography of wrists and hands to calculate bone age were performed. A tendency of increasing total body mass, stature, body mass index, body bone diameters and muscle circumferences and basic physical qualities was found with the advancing of puberty. No differences were found in dermatoglyphics and somatotype between different stages of puberty maturation. Due to the changes in important parameters of physical training that occur during puberty, it can be concluded that the selection of children and adolescents for sport training and competitions should be based not only on chronological age but also, and mainly on sexual maturation, for better physical assessment and appropriate training for this population.

Dermatoglyphics in childhood leukaemia: a guide to prognosis and aetiology?

The results of analysis of the dermatoglyphics of 152 children with acute lymphoblastic leukaemia (ALL) (and the first-degree relatives of 54 of them) contrast with those of 31 children with acute myeloblastic leukaemia (AML) (and the first-degree relatives of 25 of them). In ALL our findings suggest that neither genetic susceptibility nor an environmental factor, effective during the early antenatal period, is of aetiological importance; but the response to treatment, assessed as length of first remission, was found to be related to the amount of fingertip pattern. This may have clinical application. In AML there is evidence of a genetically determined factor carrying a high risk of the development of the disease, in that a member of each of 5 different families of the 25 studied bore a rare hypothenar pattern, compared with none in 75 control families. No dermatoglyphic features were of prognostic significance in AML. PMID:277206

Dermatoglyphics--a marker for malocclusion?

PubMed

Tikare, S; Rajesh, G; Prasad, K W; Thippeswamy, V; Javali, S B

2010-08-01

Dermatoglyphics is the study of dermal ridge configurations on palmar and plantar surfaces of hands and feet. Dermal ridges and craniofacial structures are both formed during 6-7th week of intra-uterine life. It is believed that hereditary and environmental factors leading to malocclusion may also cause peculiarities in fingerprint patterns. To study and assess the relationship between fingerprints and malocclusion among a group of high school children aged 12-16 years in Dharwad, Karnataka, India. A total of 696 high school children aged 12-16 years were randomly selected. Their fingerprints were recorded using duplicating ink and malocclusion status was clinically assessed using Angle's classification. Chi-square analysis revealed statistical association between whorl patterns and classes 1 and 2 malocclusion (p < 0.05). However, no overall statistical association was observed between fingerprint patterns and malocclusion (p > 0.05). Dermatoglyphics might be an appropriate marker for malocclusion and further studies are required to elucidate an association between fingerprint patterns and malocclusion.

Background: Dermatoglyphics and bronchial asthma (BA) are both influenced by genetic factors. Hence, we assessed the diagnostic potential of correlation between fingerprint pattern and BA. Materials and Methods: The study was carried out in out-patient Department of Pulmonary Medicine of All India Institute of Medical Sciences Bhopal. It included 36 patients of BA and 50 nonasthmatic individuals as controls. The following parameters were studied and analyzed: (a) Whorls, (b) arches, (c) radial loops, (d) ulnar loops, (e) the absolute finger ridge count (AFRC), (f) total finger ridge count (TFRC). Results: A significant decrease in the mean value of the arches and increase in the mean value of the ulnar loops were observed in BA patients compared to the control group. The mean values of TFRC, AFRC, and whorls were similar in both groups. Conclusion: Evaluation of dermatoglyphic patterns may be useful in identifying patients prone to developing BA. PMID:27003968

Objective: This study aims at examining “parent-of-origin effect” (POE) in dermatoglyphic patterns among patients with schizophrenia and non-affective psychoses. Materials and Methods: Dermatoglyphic comparison was carried out for schizophrenia patients (n=200) and healthy controls (HC) (n=100). In addition, the effect of family history and POE was examined in the dermatoglyphic pattern. Results: Schizophrenia patients compared to HC had significantly lower left total finger ridge count (LTFRC) (t=3.63, P<0.001), right total finger ridge count (RTFRC) (t=4.86, P<0.001), and absolute finger ridge count (ATFRC) (t=4.80, P<0.001) compared to HC. It was also noted that patient group had significantly higher average number of arches (t=2.20, P=0.03). The comparison between the same sex POE group and the opposite sex POE group revealed that significant differences exist in LTFRC (t=2.91, P<0.01) and ATFRC (t=2.30, P=0.02). The same sex group also had lesser number of whorls compared to opposite sex group (t=2.04, P=0.04). Conclusions: The same sex parental inheritance group seem to be more developmentally compromised than the opposite sex parental inheritance group indicating a significant POE. Complex epigenetic mechanisms along with hormonal modulation could explain the sex specific disease phenotype expression, which is a plausible explanation as in the present study. PMID:24249928

The Cummins & Midlo (1942), method was used to identify the dermatoglyphical caracteristics by the digital impressions from 10 hand digits of athletes. The study showed the following model of digital impressions: A = 0.42 +/- 0.69; L = 6.89 +/- 2.89; W = 2.74 +/- 3.14; D10 = 12.32 +/- 3.51 e SQTL = 119.37 +/- 28.99. The present study confirmed that the dermatoglyphical characteristics of the female voleybol athletes of the juvenile Brazilian team are similar to that of the adult male team. Its necessary to compare these data with the adult female voley team, in order to stablish parameters to evaluate the potencial of future athletes.

Dermatoglyphic analysis of La Liébana (Cantabria, Spain). 2. Finger ridge counts.

Martín, J; Gómez, P

1993-06-01

The results of univariate and multivariate analyses of the quantitative finger dermatoglyphic traits (i.e. ridge counts) of a sample of 109 males and 88 females from La Liébana (Cantabria, Spain) are reported. Univariate results follow the trends usually found in previous studies, e.g., ranking of finger ridge counts, bilateral asymmetry or shape of the distributions of the frequencies. However, sexual dimorphism is nearly inexistent concerning finger ridge counts. This lack of dimorphism could be related to certain characteristics of the distribution of finger dermatoglyphic patterns previously reported by the same authors. The multivariate description has been carried out by means of principal component analysis (with varimax rotation to obtain the final solution) of the correlation matrices computed from the 10 maximal finger ridge counts. Although the results do not necessarily prove the concept of developmental fields ("field theory" and later modifications), some precepts of the theory are present: field polarization and field overlapping.

Traumatic injuries are the most common cause of finger amputations. Therapeutic amputations are less common but may be essential in some patients with congenital malformations of digits. A 21-year-old female patient reported for esthetic management of malformed middle and ring finger of right hand. Examination revealed clino-syndactyly with unusual dermatoglyphics. She was successfully rehabilitated by collaborative efforts of plastic surgeon and prosthodontist, by therapeutic amputation with surgical recontouring and fabrication of somatoprosthesis. The patient was satisfied with esthetics of the prosthesis and somatoprosthesis improved function. At 6-month recall, no alterations or repair of prosthesis was required. Individualized treatment planning with integration of modifications involving a multidisciplinary approach is required to meet needs of patients with congenital digital malformations. The duplication of unusual dermatoglyphics made the prosthesis more realistic. An individualized treatment plan with modifications to conventional techniques is required to cater to rehabilitative needs of patients with congenital digital malformations. © The International Society for Prosthetics and Orthotics 2016.

Minor physical anomalies, dermatoglyphic asymmetries, and cortisol levels in adolescents with schizotypal personality disorder.

1999-04-01

A relationship between schizotypal personality disorder and schizophrenia has been documented in behavioral genetic studies, and there are similarities in the cognitive deficits and brain abnormalities associated with these disorders. Adolescents with schizotypal personality disorder are of particular interest because the postpubertal period is a critical one for the development of a DSM axis I disorder. It is likely that some schizotypal adolescents will remain stable over time, some will improve, and a subgroup will develop schizophrenia. This study tested the hypotheses that, like schizophrenic patients, schizotypal adolescents manifest an elevated rate of minor physical and dermatoglyphic anomalies, both of which suggest prenatal neurodevelopmental abnormalities. Cortisol release is also of interest because of evidence that the hypothalamic-pituitary-adrenal axis may influence the behavioral expression of vulnerability to schizophrenia. Minor physical anomalies, dermatoglyphic asymmetries, and salivary cortisol levels were measured in three groups of adolescents: 20 with schizotypal personality disorder, 20 with other personality disorders, and 26 with no disorder. Assessments began at noon, and four saliva samples were obtained at hourly intervals. The schizotypal personality disorder group showed more minor physical anomalies and dermatoglyphic asymmetries than the normal comparison group and higher cortisol levels than both of the other groups. Group differences in cortisol level were most pronounced at the beginning of the evaluation. Cortisol level and age were positively correlated. The findings support the assumption that schizotypal personality disorder is associated with perturbations in fetal neurodevelopment and, under some circumstances, a heightened cortisol response.

Cytogenetic and dermatoglyphic features were studied in a large family with an inherited 15;21 translocation. Of 35 healthy members of the family, 21 carried the translocation chromosome and 14 were chromosomally normal. There were six members with Down's syndrome who had the translocation. Dermatoglyphic studies showed that carriers of this balanced translocation had the following peculiarities significantly more often than the general population. On the hands, they had ulnar loops on the fingertips, symmetrical high terminations of the A line, symmetrical ulnar loops on the hypothenar areas, distal loops in the 3rd interdigital areas, open fields in the 4th interdigital areas, axial triradii in the distal position, and single transverse palmar creases (Sydney lines). On the feet, they had small distal loops on the hallucal area and distal loops in the 4th interdigital areas. The translocation carriers also had significantly more often than non-carrier relatives symmetrical high terminations of the A line, open fields in the 4th interdigital areas, distal axial triradii, and Sydney lines. On the feet, they had small distal loops on the hallucal areas, distal loops in the 4th interdigital areas, and tibial loops on the proximal hypothenar areas. The data obtained from this study, and especially the values of the Walker and general indices, indicate that some of the dermatoglyphic stigmata of Down's syndrome are directly associated with the 15;21 translocation carrier state and can therefore be used for predicting that state.

The aim of this study was to assess environmental and hereditary influence on development of pituitary tumors using dermatoglyphic traits. The study was performed on 126 patients of both genders with pituitary tumors (60 non-functional and 66 functional pituitary tumor patients) in comparison to the control group of 400 phenotypically healthy individuals. Statistical analysis of quantitative and qualitative traits of digito-palmar dermatoglyphics was performed, and hormonal status was determined according to the standard protocols. Although we did not find markers that could specifically distinguish functional from non-functional tumors, we have found markers predisposing to the development of tumors in general (a small number of ridges between triradius of both hands, a smaller number of ridges between the triradius of c-d rc R), those for endocrine dysfunction (increased number of arches and reduced number of whorls, difference of pattern distribution in the I3 and I4 interdigital space), and some that could potentially be attributed to patients suffering from pituitary tumors (small number of ridges for variables FRR 5, smaller number of ridges in the FRL 4 of both hands and difference of pattern distribution at thenar of I1 and I2 interdigital space). The usage of dermatoglyphic traits as markers of predisposition of pituitary tumor development could facilitate the earlier detection of patients in addition to standard methods, and possibly earlier treatment and higher survival rate. Finally, our results are consistent with the hypothesis about multifactorial nature of pituitary tumor etiology comprised of both gene instability and environmental factors.

Background: Hereditary ectodermal dysplasia is a genetic recessive trait characterized by hypohydrosis, hypotrichosis, and hypodontia. The affected individual show characteristic physiognomy like protruded forehead, depressed nasal bridge, periorbital wrinkling, protruded lips, etc. There is marked decrease in sweat and salivary secretion. Due to skin involvement palm and sole ridge patterns are disrupted. Aim: In this study an attempt has been made to classify the affected members according to the degree of penetrance by pedigree analysis and also study karyotyping for cytogenetics, dermatoglyphic analysis for the various ridge patterns and variations in the number of sweat glands by sweat pore analysis in affected individuals. Materials and Methods: A total of five families who were affected with ectodermal dysplasia were considered. Pedigree analysis was drawn up to three generation by obtaining history. Dermatoglyphics and sweat pore analysis was done by obtaining palm and finger print impression using stamp pad ink. Karyotyping was done by collecting 3–5 ml peripheral blood. Karyotyping was prepared using lymphocyte culture. Chromosomes were examined at 20 spreads selected randomly under ×100 magnification. Results were analyzed by calculating mean values and percentage was obtained. Results: Karyotyping did not show any abnormalities, dermatoglyphic analysis and sweat pore counts showed marked variations when compared with normal. Moreover, pedigree analysis confirmed the status of the disease as that of the recessive trait. Conclusion: Large number of affected patients needs to be evaluated for dermatoglypic analysis. Genetic aspect of the disease needs to be looked into the molecular level in an attempt to locate the gene locus responsible for ectodermal dysplasia and its manifestation. PMID:23248471

Background Recreational drugs have a significant impact on the lives of drug users, their close families andfriends, as well as their society. Social, psychological, biological, and genetic factors could make a personmore prone to using recreational drugs. Finger and A-B ridges (dermatoglyphics) are formed during the firstand second trimesters of fetal development, under the influence of environmental and genetic factors. Theaim of our study was to investigate and evaluate a possible link between dermatoglyphics and opium usage. Methods The pattern of dermatoglyphics - finger and A-B prints - obtained from a group of opium users(121 patients) was compared to those obtained from a group of opium non-users (121 patients) from Birjand,Iran. The results were analyzed using chi-square, t and Mann–Whitney tests. Findings The results showed that although A-B ridges of palms and fingers in our study group were highercompared to the control group, there was no significant difference between these groups. The only significantdifference was the fingerprint patterns of the left ring finger in the study group, which lacked the arch patternand had less loop patterns. The dominant type of fingerprint in the left ring finger was the whorl. In ouropium user group, the arch and loop fingerprint patterns were heterogeneous and significantly different incomparison with the control group (P < 0.01). Conclusion These findings suggest that a genetic factor may increase the predisposition to recreational drugusage. Further research is required to confirm this possible impact of genetic factors on the addiction process. PMID:27882204

  The objective of this study was to correlate dermatoglyphics and cheiloscopy with genetic inheritance in cleft lip and cleft palate patients.   This was a case-control study to look for asymmetry in finger and lip print patterns. All of the participants were divided into two equal groups (40 mothers and 40 fathers in each group). The data were analyzed by three evaluators who were blind to the study to avoid any chances of error.   A sample of 160 sporadic participants were identified and evaluated. Group A was composed of 80 healthy parents not affected by cleft lip and cleft palate but had at least one child born with nonsyndromic cleft. Group B consisted of 80 healthy parents not affected by cleft lip and cleft palate and had healthy children without cleft lip and cleft palate.   Main outcome measures were marked dermatoglyphic asymmetry and specific lip print pattern in the study group.   We found marked asymmetry in various fingerprints and specific type II and type III lip print in the study group when compared with the control group. It was observed that groove count on the lip was significantly more frequent in study group parents.   Our study determined that there is a significant correlation between increased dermatoglyphic asymmetry and specific type II and type III lip print pattern in parents of children born with cleft. This could act as an important screening marker for the prediction of cleft lip and cleft palate inheritance.

Determining the relative risk of cleft lip and palate (CL[P]) on the basis of lip prints and dermatoglyphics as genetic background may be useful for genetic counseling, and the development of future preventive measures. (1) To analyze the various pattern types of lip prints and dermatoglyphics in parents of CL(P) children and to detect if any specific type can be contemplated as a genetic marker in the transmission of CL(P). (2) To compare these patterns with that of parents of unaffected children. 31 parents of children with CL(P) as a study group, and 31 parents of unaffected children as control group were included. Lip prints and finger prints were collected from all subjects and analysis of both patterns was carried out followed by a comparison of the patterns of unaffected parents with the controls statistically. Among the mothers of the study group, type O followed by type IIa lip patterns were found to be significantly higher in upper and lower lips, and in fathers type IIa followed by type O were significantly higher. In the control group, type IIb followed by type III were higher in both fathers and mothers. Dermatoglyphic analysis of palm and finger prints revealed no significant difference in the pattern types and total ridge counts, but the Atd angle asymmetry was found to be significant between study and control group. Types IIa and O lip patterns, asymmetry of Atd angles can be considered as genetic markers for the transmission of CL(P) deformity to offsprings.

To determine if Chinese individuals with non syndromic cleft lip with or without cleft palate (CL/P) display more dermatoglyphic asymmetry than unaffected relatives or controls. Case-control study with two control groups (genetically related and unrelated). A total of 500 CL/P probands from Shanghai, China, 421 unaffected relatives, and 66 controls of Chinese heritage. Finger and palm prints were collected, and pattern frequencies, total ridge counts (TRC), and atd angles were calculated. Asymmetry scores between right and left hands were defined for each of the three dermatoglyphic measures. Probands' asymmetry scores were compared statistically with the scores of unaffected relatives and controls. In general, the probands' asymmetry scores for TRC and atd angle did not differ significantly from the scores of either unaffected relatives or controls. However, probands with a positive family history of clefting showed significantly more asymmetry in their pattern types than either probands without a family history, unaffected relatives or controls. These results suggest that a unique genetic mechanism of developmental instability may obtain in CL/P individuals with a positive family history of clefting.

Dermatoglyphics in dermatitis herpetiformis.

Roberts, D F; Abdullah, N; Marks, J; Shuster, S

1978-12-01

In a dermatoglyphic study of 101 patients with dermatitis herpetiformis, comparison was made with their normal relatives and several random normal series. The results of the several comparisons are quite consistent, considering the nature of the data, for the all point to an attenuation of qualitative and quantitative digital and palmar traits in the patients. It is argued that these differences are associated with the disease itself, and that some of the female relatives have an inherited tendency to the disorder, but do not express it. The findings suggest the involvement of genetic factors in the aetiology, and possibly intrauterine environmental influences as well.

The role of genetic factors in the determination of palmar dermatoglyphic patterns was investigated in a series of 49 MZ and 51 DZ twins, using Spearman's rank correlation and analysis of variance. Both methods indicated that the genetic effect in the distribution of patterns is highest in the interdigital III and lowest in the interdigital IV regions, the hypothenar and thenar showing intermediate values. As for interdigital II, no evaluation of genetic effects was possible using the nonparametric test, but the estimates of genetic variance indicate that inherited factors may play a relatively minor role in the pattern distribution of this area.

Palm prints formed once does not change throughout life and is not influenced by environment. Palmar Dermatoglyphics can indicate the development of potentially malignant and malignant lesions and help in identifying persons at high risk of developing Oral submucous fibrosis (OSMF) and Oral squamous cell carcinoma (OSSC). To analyze the qualitative [finger ridge pattern and presence or absence of hypothenar pattern] and quantitative [mean ATD angle and total AB ridge count] variations in Palmar Dermatoglyphics in patients suffering from OSMF and OSCC. A prospective comparative study among 40 patients (Group I--10 samples of smokeless tobacco users with OSMF, Group II--10 samples of smokeless tobacco users with OSCC, Group III--10 samples of smokeless tobacco users without OSMF or OSCC and Group IV--10 samples without smokeless tobacco habit without OSMF and OSCC as controls) were selected. The palm prints were recorded using an HP inkjet scanner. The patients were asked to place the palm gently on the scanner with the fingers wide apart from each other. The images of the palm prints were edited and qualitative and quantitative analysis were done. Statistical analysis such as Kruskal Wallis, Post Hoc and Analysis of Varience were done. A highly significant difference among the finger ridge, hypothenar pattern and mean ATD angle (P<0.001) and total AB ridge count (P=0.005) in OSMF and OSCC patients were obtained. There is predominance of arches and loops, presence of hypothenar pattern, decrease in mean ATD angle and total AB ridge count in OSMF and Oral Cancer patients. Palmar Dermatoglyphics can predict the probable occurrence of OSMF and OSCC in smokelees tobacco users.

Widespread interest in epidermal ridges developed only in the last several decades; however, it is still at infancy in the world of dentistry. The word "dermatoglyphics" comes from two Greek words (derma: Skin and glyphe: Carve) and refers to the epidermal skin ridge formations which appear on the fingers, palms of the hands, and soles of the feet. This study aims to assess the relationship between finger prints and chronic periodontitis. Two hundred patients were equally divided into chronic periodontitis and periodontally healthy group. The fingerprint patterns of the participants were recorded with a rolling impression technique using duplicating ink on executive bond paper. The descriptive analysis of the data was presented as percentage frequency. The percentage frequencies of each pattern on each individual finger were calculated, and statistical tests were applied. Unpaired t-test was used for intergroup comparisons (P < 0.05). There were statistically more whorls and less arches in both right and left hands in patients with chronic periodontitis. Dermatoglyphics can lead to early diagnosis, treatment, and better prevention of many genetic disorders of the oral cavity and other diseases whose etiology may be influenced directly or indirectly by genetic inheritance.

Dermatoglyphic asymmetries and fronto-striatal dysfunction in young-adults reporting non-clinical psychosis

Objective Growing evidence indicates that non-clinical psychotic-like experiences occur in otherwise healthy individuals, suggesting that psychosis may occur on a continuum. However, little is know about how the diathesis for formal psychosis maps on to individuals at the non-clinical side of this continuum. Our current understanding of the pathophysiology of schizophrenia implicates certain key factors such as early developmental abnormalities and fronto-striatal dysfunction. To date, no studies have examined these core factors in the context of non-clinical psychosis. Method A total of 221 young adults were assessed for distressing attenuated positive symptoms (DAPS), dermatoglyphic asymmetries (a marker of early developmental insult), and procedural memory (a proxy for fronto-striatal function). Results Participants reporting DAPS (n=16; 7.2%) and no-DAPS (n=205; 92.7%) were split into two groups. The DAPS group showed significantly elevated depression, elevated dermatoglyphic asymmetries, and a pattern of procedural learning consistent with other studies with formally psychotic patients. Conclusion The results indicate that the non-clinical side of the psychosis continuum also shares key vulnerability factors implicated in schizophrenia, suggesting that both early developmental disruption and abnormalities in fronto-striatal function are core aspects underlying the disorder.

The aim was to compare digital and palmar dermatoglyphics in subjects with dementia of Alzheimer type and in mentally healthy elderly controls. This design was a case-control study. The study was carried out in geriatric units and retirement communities in the Paris area. Cases were women with clinically diagnosed Alzheimer type dementia according to DSM III-R criteria (n = 82), mainly with late onset of the disease. Controls were women aged 85 years or older without cognitive deterioration (n = 76). Finger and palm prints obtained from both hands by the classical ink method were examined. Fingerprints were classified into four types of figures. On palms, palmar flexion creases, palmar axial triradii, true patterns of the hypothenar area, and main line terminations were described. Examinations were performed by two examiners blind to the subjects's diagnostic category. For the different patterns studied, no major differences between dementia patients and elderly controls were found. Nor was there evidence of high frequencies of features commonly observed in Down's syndrome (trisomy 21), which have previously, though sporadically, been reported. On one of the largest samples of Alzheimer dementia patients studied, and with evaluation blind to diagnosis, no evidence has been found that particular dermatoglyphic patterns occur like those observed in Down's syndrome, a disease which is related to dementia of the Alzheimer type.

Introduction Bronchial Asthma is one of the most extensively studied respiratory diseases and its genetic basis is well established. Dermatoglyphic traits are formed under genetic control early in development but may be affected by environmental factors during first trimester of pregnancy. These patterns may represent the genetic makeup of an individual and therefore his/her predisposition to certain diseases. Patterns of dermatoglyphics have been studied in various congenital disorders like Down’s syndrome, Klinefelter’s syndrome and also in chronic diseases like Hypertension, Diabetes Mellitus etc. Epidermal ridge patterns of finger tips in bronchial asthma patients were studied to find out fingertip pattern as Dermatoglyphic features in patients of Bronchial Asthma; it’s comparison and association if exists between normal and bronchial asthma patients and also to find use of fingertip pattern in early childhood as non-invasive anatomical marker for bronchial asthma in adulthood. Methods The study was conducted on clinically diagnosed all bronchial asthma patients attending OPD of Dr Ulhas Patil Medical College, Jalgaon. Matched controls were selected without any respiratory problem or any symptoms related to asthma from medical students, staff members and paramedical staff of hospital after taking the informed consent and permission from the institutional ethical committee. Data collection and fingertip prints were taken by ink and rolling finger method. Prints taken were analysed and tabulated; data was analysed by using statistical tests. Results Study shows that decrease in number of arches, increase in AFRC in patients as compared with controls. Also there were increased ulnar loops in male patients and increased Whorls and radial loops in female patients. Conclusion The fingerprints can represent a non-invasive anatomical marker of bronchial asthma risk and facilitate early detection and effective management which is vital for selecting appropriate agents for treating infections.

Capecitabine-Associated Loss of Fingerprints: Report of Capecitabine-Induced Adermatoglyphia in Two Women with Breast Cancer and Review of Acquired Dermatoglyphic Absence in Oncology Patients Treated with Capecitabine

PubMed Central

2017-01-01

Capecitabine, an oral 5-fluorouracil prodrug, is currently used in the treatment of metastatic colorectal carcinoma and breast cancer. Fingerprints, also referred to as dermatoglyphics and characterized by the pattern of ridges and furrows on the fingertips, are used for identification by government agencies and personal electronic devices. Two women with breast cancer who were treated with capecitabine and developed drug-associated loss of their fingerprints are described. PubMed was used to search the following terms separately and in combination: absence, adermatoglyphia, breast, cancer, capecitabine, carcinoma, colon, colorectal, dermatoglyphics, fingerprint, fluorouracil, foot, hand, loss, malignancy, nasopharyngeal, oncology, reaction, rectal, skin, syndrome, tumor, and xeloda. The papers identified were reviewed and appropriate references were evaluated. The characteristics of capecitabine-induced adermatoglyphia in 20 oncology patients are reviewed. Most of the patients received either 2000 mg/m2 or 3500 mg, in divided doses, each day. Hand-foot syndrome, varying in severity from grade 1 to grade 4, always preceded the onset of fingerprint loss. The discovery of adermatoglyphia occurred as early as two weeks to as late as 3½ years after starting capecitabine. Patients were often unaware of their fingerprint loss until they experienced delays attempting to enter the United States, were unable to process government documents or obtain a driver’s license, or could not obtain access to their telephone, computer or gym which required fingerprint identification scanning. The loss of fingerprints was reversible for some of the individuals; however, several of the patients did not recover their dermatoglyphics, the functional quality of their fingerprints, or both after discontinuing the drug. The significance of capecitabine-induced adermatoglyphia will continue to increase as fingerprint identification continues to advance not only in scanning technology but also in global utilization. Therefore, it is essential that patients receiving capecitabine are aware of this potential adverse cutaneous sequellae. PMID:28191373

1962-10-20

Cytogenetic and dermatoglyphic features were studied in a family in which the mongoloid propositus inherited a 13-15/21 translocation chromosome from his father. Seven other healthy male carriers scattered throughout the pedigree produced nine chromosomally normal children and five carrier children in addition to the mongoloid propositus. These results show that carrier males do not necessarily produce an unusually large proportion of carrier children as previous reports would indicate. Dermatoglyphic studies showed that translocation carriers in this family have neither significantly more centralized nor less centralized palmar axial triradii than non-carrier relatives. No direct evidence was therefore found for the hypothesis that an allele is present on chromosome 21 which influences the height of the triradius.

Dermatoglyphic features in Prader-Willi syndrome with respect to chromosomal findings

PubMed Central

Reed, Terry; Butler, Merlin G.

2017-01-01

Dermatoglyphic findings were compared in 38 Prader-Willi syndrome (PWS) patients and 270 normal controls. Twenty-one of the PWS patients had an interstitial deletion of the proximal long arm of chromosome 15 and seventeen PWS cases had normal chromosomes. Findings in PWS are not diagnostic but do show some consistent deviations that can be used in the clinical evaluation of PWS patients. These include a displacement of the axial triradius away from the normal proximal position, an excess of whorls primarily on the thumbs, radial termination of the palmar A mainline, and lack of arches on the big toe. Deletion PWS patients were much more homogeneous than non-deletion cases with respect to plantar patterns. The previously reported deficit of plantar pattern intensity was restricted only to deletion PWS and was characterized by a lack of plantar interdigital II–IV patterns with almost exclusively hallucal distal loops.

Dermatoglyphics can be found in the thick skin of both hands and feet which make the identification process possible, however morphological changes throughout life can affect identification in elderly individuals. Considering that dermatoglyphics is an important biometric method, due to it being practical and inexpensive, this longitudinal and retrospective study was aimed to evaluate the morphological variations in fingerprints obtained from men and women (n=20) during their adult and elderly stages of life; the time between obtaining the two fingerprints was 33.5±9.4 years. For the morphometric analysis, an area of 1 cm(2) was selected to quantify the visible friction ridges, minutiae, interpapillary and white lines, and later side-by-side confrontation was used to determine the identity of the individuals. Our results showed a reduction of friction ridges, an increase in the number of white lines for the group (men and women) and a decrease in the number of interpapillary lines in the group of women. It also showed that the selection of compatible fingerprints by the automated AFIS/VRP system allowed the identification of 23 individuals (57.5%), but when the identification was made by the automated AFIS/VRP system, followed by the analysis of archived patterns to eliminate incompatible fingerprints, determination of the identity of 28 individuals (70.0%) was possible. The dermatoglyphics of the elderly suffered morphometric changes that prevented the identification of 30% of them, probably due to the aging process, and pointed to the importance of improving the methods of obtaining fingerprints to clarify issues related to the identification of the elderly.

The article shows the results of a research into 22 quantitative features of the digito-palmar complex, and 2 features of the plantar area in 400 persons. No significant differences were found in the parameters of the observed variables between fathers and sons, nor mothers and daughters. The differences were found, however, between fathers and daughters, and mothers and sons. The analysis of the correlation coefficients within the families showed that only the variables TRC and TPRC have polygenic hereditary model. The correlative analyses have shown close links between parents and children, the link between parents and sons being stronger than the link between parents and daughters. The research has not confirmed the thesis about greater overlap between mother and children, than between father and children, set forth by Knussmann in 1973.

Two sisters and their mother had a syndrome of microcephaly, cleft palate, and variable anomalies such as unusual facial appearance, hypotelorism, abnormal retinal pigmentation, maxillary hypoplasia, goiter, camptodactyly, mild mental retardation, and abnormal dermatoglyphics. This is an evidently dominantly inherited trait, either autosomal or X-linked.

We assessed the genetic rules for the dermatoglyphics of human fingertips. We also evaluated the correlation between spouse selection with the number of whorls on fingertips. Data were collected for the number of whorls from 118 families (couples and their children). Distribution of whorls was analyzed further to investigate the relationship between heredity and spouse selection. Through multiple regression analysis, we found that the number of whorls on fingertips was affected considerably by genetic factors. In a married couple with a moderate number of whorls, the probability of their children having a high number of whorls was 26.5 %, and the probability of their children having a low number of whorls was 23.5. These values were close to the theoretical value (25 %). A significant correlation between whorl count between spouses was observed. These data suggest that whorls are inherited from a single gene or a group of closely linked genes. Our findings provide an initial insight on the potential contribution of biologic characteristics on spouse selection.

Hypohidrotic ectodermal dysplasia: dental, clinical, genetic and dermatoglyphic findings of three cases.

Patients with hypohidrotic ectodermal dysplasia (HED) are characterized by the clinical manifestations of hypodontia, hypohidrosis, hypotrichosis and a highly characteristic facial physiognomy. This disorder is inherited as an X-linked trait. This report presents three cases with HED in which the clinical evaluation (intraoral and radiological), genetic findings and SEM examination of hair. Boys 6 to 14 year old and a 11 year old girl were referred to the Marmara University, Faculty of Dentistry, complaining of oligodontia in the maxillary and mandibular arches and delay in eruption of other teeth. Peg-shaped teeth have been observed. The dermatoglyphs of the patients were striking. SEM examination of hair demonstrated a distinctly abnormal longitudinal grooving along the entire length of each hair and a desquamation of the surface cuticles. The treatment was planned in a multidisciplinary odontological group involving pediatric dentistry, orthodontics, prosthodontics and oral surgery and maxillofacial radiology of future dental habilitation. A specially designed overdenture, a removable prosthesis and osseointegrated implants were constructed. Periodic recall visits were advised, to monitor the dentures and implants during periods of growth and development, and eruption of the permanent teeth.

Piagetian scales and the Bender visual motor gestalt test (BT) were applied to 28 subjects with universal 45,X Turner syndrome (TS), and their respective controls, in order to investigate their cognitive performance. Dermatoglyphics were also analyzed to obtain clues concerning embryological changes that may have appeared during development of the nervous system and could be associated with cognitive performance of TS patients. Dermatoglyphic pattern distribution was similar to that reported in previous studies of TS individuals: ulnar loops in the digital patterns and finger ridge, a-b, and A'-d counts were more frequent, while arch and whorl patterns were less frequent compared to controls. However, we did not find higher frequencies of hypothenar pattern, maximum atd angle, and ulnarity index in our TS subjects, unlike other investigations. Furthermore, we found significant differences between TS and control T line index values. The BT scores were also lower in probands, as has been previously reported, revealing a neurocognitive deficit of visual motor perception in TS individuals, which could be due to an absence of, or deficiency in, cerebral hemispheric lateralization. However, TS subjects seemed to improve their performance on BT with age. Cognitive performance of the TS subjects was not significantly different from that of controls, confirming a previous study in which TS performance was found to be similar to that of the normal Brazilian population. There were significant correlations between BT scores and Piagetian scale levels with dermatoglyphic parameters. This association could be explained by changes in the common ectodermal origin of the epidermis and the central nervous system. TS subjects seem to succeed in compensating their spatial impairments in adapting their cognitive and social contacts. We concluded that genetic counseling should consider cognitive and psychosocial difficulties presented by TS subjects, providing appropriate treatment and orientation for them and their families.

We investigate a mechanical cell-traction mechanism that generates stationary spatial patterns. A linear analysis highlights the model's potential for these heterogeneous solutions. We use multiple-scale perturbation techniques to study the evolution of these solutions and compare our solutions with numerical simulations of the model system. We discuss some potential biological applications among which are the formation of ridge patterns, dermatoglyphs, and wound healing.

Somatotype, finger dermatoglyphic pattern type, emotional stability level and foreign languages learning successfulness have been analyzed in 297 male cadets (aged 17-20 years) of the Military Institute of Physical Training. The cadets studied most frequently belonged to macrosomal and mesosomal somatotypes. In the study of finger patterns, loops were found to be most common (61.5% of all the patterns), while ringlets (33.4%) and arc patterns (5.1%) were less frequent. The amount of ulnar loops increased, while that of ringlets became less in the direction from micro- to macrosomal type. Almost half (46.9%) of the cadets appeared to be ambiverts, 30.8% were intraverts and the rest were extraverts. Loop patterns on all the fingers to a greater extent were found in cadets with high level of neuroticism; the cadets having lower neuroticism level were characterized by a combinations of loops with arcs on the left hand and arcs with ringlets on the right one. The cadets differing in foreign language learning successfulness level were different in their dermatoglyphic patterns and, especially in the prevalence of pattern combinations. So, among the excellent pupils the loop-arc combinations were 2.7 times more common and combinations of all three types of patterns (arcs, loops, ringlets) were 1.4 times more common.

Although the association between the type of idiopathic nephrotic syndrome (INS) and a peculiar pattern of fingerprints digital would suggest the presence of genetic factors related to both, this has not been previously studied. This study aimed to evaluate if there are fingerprints patterns differences between children with steroid-resistant INS (SRNS) and those with steroid-sensitive INS (SSNS). The frequencies distribution of arches, ulnar loops, radial loops, and whorls was studied in 60 children with SRNS, and 60 children with SSNS. Bivariate analysis to detect the relationship between each fingerprint pattern with the study groups was performed by chi-square test and to evaluate its possible association, the odds ratios (OR) were calculated with 95% confidence's intervals (95%CI). The patients with SRNS had a higher frequency of digital whorls compared with that of patients with SSNS (46.7% vs. 30.7%, p = 0.005). Additional comparisons using a "whorls excesses" definition obtained from normative data in our population (≥ 7 whorls in females or ≥ 8 in males) were associated with increased odds for SRNS (OR 2.96, 95% CI 1.15-7.61). Our findings indicate that there are differences between children with SRNS and SSNS at the level of digital dermatoglyphics, but further studies are needed to confirm this association and its possible implications.

Since the original description of cerebral gigantism, about 85 cases have been reported. Four papers comment on familial occurrence but never in parents and their children. This paper describes the syndrome in a mother and her child, which, together with facts pointing towards prenatal etiology, such as excessive birthweight, striking mutual resemblance and abnormal dermatoglyphics, points to a genetic defect. Previous endocrine studies are enlarged by the findings of normal serum somatomedin and serum prolactin.

Eight patients in three families had mental retardation, characteristic facies and hands, and skeletal changes; the clinical features suggested to us that they had a syndrome previously thought to represent two entities described by Lowry and associates and by Coffin and associates, respectively. New findings include skeletal, orodental, and dermatoglyphic abnormalities and histopathologic changes suggesting that the syndrome is a heritable disorder of connective tissue. Severe expression in males and transmission through mildly affected females suggest X-linked or sex-influenced autosomal dominant inheritance.

A family study of dermatoglyphic traits in India: segregation analysis of accessory palmar triradii and the atd angle.

1987-09-01

Accessory triradii and the atd angle were examined via complex segregation analysis in order to evaluate possible genetic effects on these dermatoglyphic traits, measured in an endogamous Brahmin caste of peninsular India. The phenotypes considered included: presence of accessory palmar triradii a' and d', associated with the interdigital areas II and IV, respectively; presence of an accessory axial triradius tt' associated with the proximal margin of the palm; and an arctanh-transformation of the atd angle measurement. For all accessory triradii considered in the present investigation familial resemblance was evident. The most parsimonious model which could account for the observed resemblance was a multifactorial model that includes polygenic effects as well as transmissible environmental effects that are inherited in the same pattern as polygenes. Evidence of familial resemblance was also found for the arctanh-transformed atd angle, which could be attributed, initially, to both a major effect and a multifactorial component. Tests of transmission of a putative major gene were performed which yielded results consistent with Mendelian transmission, although an alternative test of no transmission of the major effect also fit the data. In light of these contrasting results we are precluded from accepting with confidence the notion of a major gene influence on the atd angle. We have concluded that the accessory triradii a', d', and tt', and the atd angle are influenced by multifactorial effects, including additive polygenes and possible environmental factors, such as intrauterine effects.

We report a large consanguineous Saudi-Arabian pedigree containing 11 individuals with the autosomal recessive genodermatosis, Kindler syndrome. Three affected cases died in infancy but the remaining eight had signs of photosensitivity, generalized poikiloderma, webbed fingers, loss of dermatoglyphics and nail dystrophy. The majority also had oral involvement with bleeding gums. Additional features seen in some cases included pseudoainhum of the toes, sclerotic bands on the wrists and hand deformities. The aetiology of Kindler syndrome is not yet known, but the underlying defect leads to both cutaneous and oral inflammation, along with photosensitivity and scarring.

Four individuals from 2 generations of a family had a hidrotic type of ectodermal dysplasia (ED). Males and females were similarly affected. They had trichodysplasia, with absent eyebrows and eyelashes; normal teeth, onychodysplasia; normal sweating; mild retrognathia; abnormal dermatoglyphics; and mental retardation. Additional variable manifestations included irregular menses, high implanted or prominent ears, café-au-lait spot, keratosis pilaris, supernumerary nipple, and mild hearing loss. Their previously undescribed condition could be classified as an ED of 1-3 (trichoonychial) subgroup of group A according to Freire-Maia's classification and is inherited as an autosomal recessive trait.

The morphological diversity of dermatoglyphic patterns on fingers: a simple and objective method for measurement.

PubMed

Buchwald, Wiesław

2015-02-01

The paper contains a proposal for a simple way of measuring the morphological diversity of patterns on fingers. The mono/polymorphism index (Imp) is the sum of 45 mutual absolute differences between the numerical values of the patterns depending on their degree of morphological complexity. Wendt's 7-degree scale was used to quantify the patterns. The value Imp=0 denotes monomorphism, i.e., the presence of the same type of pattern on all the fingers of both hands, while high values denote a mosaic of patterns of diverse morphology (polymorphism). Elements of the individual values of the Imp index comprise mutual homolateral differences (10 differences for the fingers of the left hand and 10 differences for the right), on the basis of which an assessment was made between the sides of the body, and additionally 25 heterolateral differences. Generally, greater degree of morphological diversity in patterns is found in males, and on the fingers of the right hand in both sexes. The arithmetic mean of the Imp index differs significantly between males (55.17) and females (52.08). Its values are not directly related to the degree of morphological complexity of patterns included in the Wendt's index. There were found, however, intra-familial connections for this trait. In light of the values of the indices of correlation and association, it may be concluded that there are relatively weak but statistically significant parents-offspring relations, as well as between siblings. An objective way to determine the values of the Imp index would make it possible to use it both for the morphological characterization of dermatoglyphs in different populations and also in clinical, auxological and genetic research.

2006-01-01

Naegeli-Franceschetti-Jadassohn syndrome (NFJS) and dermatopathia pigmentosa reticularis (DPR) are two closely related autosomal dominant ectodermal dysplasia syndromes that clinically share complete absence of dermatoglyphics (fingerprint lines), a reticulate pattern of skin hyperpigmentation, thickening of the palms and soles (palmoplantar keratoderma), abnormal sweating, and other subtle developmental anomalies of the teeth, hair, and skin. To decipher the molecular basis of these disorders, we studied one family with DPR and four families with NFJS. We initially reassessed linkage of NFJS/DPR to a previously established locus on 17q11.2-q21. Combined multipoint analysis generated a maximal LOD score of 8.3 at marker D17S800 at a recombination fraction of 0. The disease interval was found to harbor 230 genes, including a large cluster of keratin genes. Heterozygous nonsense or frameshift mutations in KRT14 were found to segregate with the disease trait in all five families. In contrast with KRT14 mutations affecting the central α-helical rod domain of keratin 14, which are known to cause epidermolysis bullosa simplex, NFJS/DPR-associated mutations were found in a region of the gene encoding the nonhelical head (E1/V1) domain and are predicted to result in very early termination of translation. These data suggest that KRT14 plays an important role during ontogenesis of dermatoglyphics and sweat glands. Among other functions, the N-terminal part of keratin molecules has been shown to confer protection against proapoptotic signals. Ultrastructural examination of patient skin biopsy specimens provided evidence for increased apoptotic activity in the basal cell layer where KRT14 is expressed, suggesting that apoptosis is an important mechanism in the pathogenesis of NFJS/DPR.

2013-01-01

Introduction: Dermatoglyphics is a collective term for all the integumentary features (skin patterning of the fingers, toes, palms and soles) and it applies to the division of the anatomy which embraces their study. Aims and Objectives: The purpose of this study was to examine the predominant finger tip patterns in the patients of carcinoma breast. An attempt is also being made to devise a score to assess the risk variables. Materials and Methods: The fingerprints of 100 carcinoma breast patients were obtained and they were compared with those of 100 females who were not suffering from any malignancy till date. The different quantitative parameters of each hand of both the cancer patients and the controls were studied. The parameters which were included were the fingertip ridge pattern, the ridge count in the individual fingers, the Total Finger Ridge Count (TFRC) and the Absolute Finger Ridge Count (AFRC). Results: There was a significant increase in the arch pattern and a decrease in the radial loops in the right thumb (p<0.001), the left thumb (p<0.001), the left index finger (p<0.001) and the left middle finger (p<0.001). A comparison of all the five fingers of both the left and right hands of the cancer patients with the controls showed an arch pattern (p<0.001) with the highest frequency. The lower values of the TFRC (below 50) were associated with carcinoma breast .The lower values of the AFRC (below 100) were associated with the cancer patients. Conclusion: This study was able to establish a specific finger tip predominance in the Carcinoma breast patients. PMID:23730629

We report a 14-month-old girl with a symmetrical paralysis from birth, limited to the upper limbs and resembling a severe, complete bilateral brachial plexus palsy. The presence of dimples over the wrists, shoulders and scapulae and abnormal palmar dermatoglyphics suggested an early prenatal onset. Previous reports and the course of the disease in our case suggest this sporadic condition is not progressive. Although no definitive causative factor has been identified in previously reported cases, the affection in our case is possibly related to Debendox (Bendectin) and nitrofurantoin taken in early pregnancy for nausea and renal tract infection, respectively.

This is an attempt to describe a common syndrom of polygonosomy. Medical, psychological and social incidences of XXX, XXY, XYY, genotypes indicate that these chromosomal aberrations share identical features: phenotypic abnormalities (high stature, dermatoglyphes abnormalities), neuropsychic troubles (neurological symptoms and mental fragility) and antisocial tendancy. One can suppose that at least some polygonosomic persons have a minimal brain dysfunction (or damage), which causes more vulnerability to environnement, deprivation and stress. Relational, educational and socio-economical factors appear now to have a marked role in the etiopathogenesis of these psychiatric troubles. Some forensic and ethical problems of human genetic research are reviewed, such as the so-called "criminal chromosome", supplementary Y chromosome, a myth based upon false and premature scientific assertions.

Two cases are reported of familial partial trisomy 6q syndrome due to segregation of ins(5;6) (q33;q15q27) in three generations. The common clinical features include growth and mental retardation, feeding difficulty during infancy, microcephaly with downward slanting palpebral fissures, flattened nasal bridge with anteverted and flared nares, long philtrum, high arched palate, partially opened and protruding mouth with receding chin, deep transverse creases of the ears, three creases on the 4th fingers, clinodactyly of the 5th fingers with a single crease, and other dermatoglyphic findings. These characteristic features of two patients appear to make partial trisomy 6q a clinically recognizable syndrome.

Reticulate acropigmentation of Kitamura (RAK) and Dowling-Degos Disease (DDD) are rare genodermatosis inherited as an autosomal dominant trait with variable penetrance. They are part of a spectrum of diseases with hyperpigmented macules coalescing in a reticular pattern, facial and palmoplantar pits, breaks in dermatoglyphics, comedo-like lesions and epidermoid cysts, and a unique histological picture of hyperpigmented digitate epidermal downgrowths. The authors describe the case of a 45-year-old female with reticulate acropigmentation of the dorsa of the hands and feet, hyperpigmented macules on the axilla and around the mouth, and palmar pitting. Clinical and histological findings, together with a relevant family history, allowed the authors to consider this case an example of the rare event of an overlap RAK-DDD.

Inherited congenital bilateral atresia of the external auditory canal, congenital bilateral vertical talus and increased interocular distance.

Six out of twenty descendants of a reportedly affected grandfather have congenital bilateral symmetrical and isolated subtotal atresia of the external auditory canal. Four of the six affected descendants have bilateral foot anomalies--two affected cousins having congenital vertical talus. All of the three affected boys in the third generation have increased interocular distance. Short fifth fingers, bilateral single transverse palmar creases, pyloric stenosis and congenital exotropia were found infrequently and are considered coincidental features. Apart from the atresia, oto-rhinolaryngologic examination, mental function, dermatoglyphics, IgA, kidney function and heart function of the affected descendants were all normal. The karyotype of four affected descendants examined was normal. An autosomal dominant inheritance with variable expressivity is suggested.

2007-01-01

This paper examined the association between grip type, hand use, and fingerprint patterns in a sample of captive chimpanzees. Grip type for simple reaching was assessed for the left and right hand and classified as thumb-index, middle-index, or single-digit responses. Fingerprint patterns were characterized as whorls, loops, or arches on each finger. The results indicated that chimpanzees exhibit significantly more thumb-index responses for the right compared to the left hand. In addition, thumb-index responses were more prevalent for subjects that had a whorl compared to a loop or arch on their thumb. The results suggest that fingerprint patterns are associated with individual differences in grasping type in chimpanzees as well as some variation in hand use. PMID:15761856

Congenital sensori-neural deafness associated with onycho-osteo dystrophy and mental retardation (D.O.O.R. syndrome).

PubMed

Cantwell, R J

1975-01-01

A characteristic syndrome is described in which congenital sensori-neural deafness is associated not only with onychodystrophy but also with congenital bony anomalies the most characteristic of which are tri-phalangeal thumbs, bi-phalangeal digits of hands and feet, and dystrophic terminal phalanges of some of the fingers and toes. In addition, there is mental retardation and the dermatoglyphics are characterized by the presence of 10 arches and elevation of the atd angles. The syndrome is inherited as an autosomal recessive. It is suggested that this entity be named the D.O.O.R. Syndrome because of the deafness, onychodystrophy, osteodystrophy and retardation. A similar syndrome without retardation as described by Goodman et al. (1969) appears to be inherited as an autosomal dominant.

On the mechanical theory for biological pattern formation

Bentil, D. E.; Murray, J. D.

1993-02-01

We investigate the pattern-forming potential of mechanical models in embryology proposed by Oster, Murray and their coworkers. We show that the presence of source terms in the tissue extracellular matrix and cell density equations give rise to spatio-temporal oscillations. An extension of one such model to include ‘biologically realistic long range effects induces the formation of stationary spatial patterns. Previous attempts to solve the full system were in one dimension only. We obtain solutions in one dimension and extend our simulations to two dimensions. We show that a single mechanical model alone is capable of generating complex but regular spatial patterns rather than the requirement of model interaction as suggested by Nagorcka et al. and Shaw and Murray. We discuss some biological applications of the models among which are would healing and formation of dermatoglyphic (fingerprint) patterns.

107 patients with Itsenko-Cushing disease were examined for heredity: family history was analyzed in 75 cases, dermatoglyphics was assessed in 44 cases, I- and II-class HLA antigens were studied in 68 cases. The patients were found to have hereditary loading both by Itsenko-Cushing and other diseases (hypertension, atherosclerosis, autoimmune disorders). Clinico-genealogical evaluation made it possible to identify forms of the disease which are inherited autosome-recessively and autosome-dominantly. However, in the majority of patients the disease onset had multifactorial nature, as there were HLA-antigen associations by DR4, DR5, DR7, DRw53, DQw3. Pilot experience with genetic study of the disease showed its genetic determination in some forms, its association with hypertension and atherosclerosis, approaches to prevention, prognosis, classification. Practical recommendations on detailed family history collection in patients with Itsenko-Cushing disease have been developed.

We describe 5 Spanish children with Kabuki make-up syndrome (KMS) - 3 females and 2 males - identified in Badajoz, Spain, between 1988 and 1990. All had the characteristic clinical and radiological manifestations of the syndrome. Psychomotor/mental retardation, postnatal growth deficiency, distinctive facial appearance, sagittal vertebral clefts, and dermatoglyphic abnormalities were present in all 5. Congenital heart defects were present in 4 patients. In addition, one had myopia, astigmatism, and bilateral paralysis of the VI cranial nerve. Another had apparent fusion of the hamate and capitate. An additional patient, as well as his mother, had an apparently balanced 15/17 translocation.more » The fact that these patients were ascertained in a catchment area of approximately 250,000 inhabitants and in a relatively limited period of time suggests that the prevalence of the KMS may be higher than previously recognized. 30 refs., 6 figs., 2 tabs.« less

The Wisconsin Twin Research Program comprises multiple longitudinal studies that utilize a panel recruited from statewide birth records for the years 1989 through 2004. Our research foci are the etiology and developmental course of early emotions, temperament, childhood anxiety and impulsivity, autism, sensory over-responsivity, and related topics. A signature feature of this research program is the breadth and depth of assessment during key periods of development. The assessments include extensive home- and laboratory-based behavioral batteries, recorded sibling and caregiver interactions, structured psychiatric interviews with caregivers and adolescents, observer ratings of child behavior, child self-report, cognitive testing, neuroendocrine measures, medical records, dermatoglyphics, genotyping, and neuroimaging. Across the various studies, testing occasions occurred between 3 months and 18 years of age. Data collection for some aspects of the research program has concluded and, for other aspects, longitudinal follow-ups are in progress.

Permutation methods for the structured exploratory data analysis (SEDA) of familial trait values.

PubMed

Karlin, S; Williams, P T

1984-07-01

A collection of functions that contrast familial trait values between and across generations is proposed for studying transmission effects and other collateral influences in nuclear families. Two classes of structured exploratory data analysis (SEDA) statistics are derived from ratios of these functions. SEDA-functionals are the empirical cumulative distributions of the ratio of the two contrasts computed within each family. SEDA-indices are formed by first averaging the numerator and denominator contrasts separately over the population and then forming their ratio. The significance of SEDA results are determined by a spectrum of permutation techniques that selectively shuffle the trait values across families. The process systematically alters certain family structure relationships while keeping other familial relationships intact. The methodology is applied to five data examples of plasma total cholesterol concentrations, reported height values, dermatoglyphic pattern intensity index scores, measurements of dopamine-beta-hydroxylase activity, and psychometric cognitive test results.

We describe a woman with a probable autosomal recessive ectodermal dysplasia with corkscrew hairs and mental retardation in a family with tuberous sclerosis. Other findings included syndactyly, typical facies, dental abnormalities, dermatoglyphic hypoplasia, epidermal ridge sweat pore count slightly below normal, and keratosis pilaris. Clinical studies and genetic analysis excluded the diagnosis of tuberous sclerosis in our patient. We conclude that she has ectodermal dysplasia associated with mental retardation. This association has been described previously; it suggests the possible interrelationship of a community of ectodermal dysplasia syndromes with a distinctive structural hair abnormality (pili torti et canaliculi), variable midfacial malformations, limb defects, and other features such as mental retardation. The similarity of our patient to that described by Whiting et al. and Abramovits-Ackerman et al. suggests the autonomy of this syndrome.

Prenatal sex hormone effects on child and adult sex-typed behavior: methods and findings.

There is now good evidence that human sex-typed behavior is influenced by sex hormones that are present during prenatal development, confirming studies in other mammalian species. Most of the evidence comes from clinical populations, in which prenatal hormone exposure is atypical for a person's sex, but there is increasing evidence from the normal population for the importance of prenatal hormones. In this paper, we briefly review the evidence, focusing attention on the methods used to study behavioral effects of prenatal hormones. We discuss the promises and pitfalls of various types of studies, including those using clinical populations (concentrating on those most commonly studied, congenital adrenal hyperplasia, androgen insensitivity syndrome, ablatio penis, and cloacal exstrophy), direct measures of hormones in the general population (assayed through umbilical cord blood, amniotic fluid, and maternal serum during pregnancy), and indirect measures of hormones in the general population (inferred from intrauterine position and biomarkers such as otoacoustic emissions, finger length ratios, and dermatoglyphic asymmetries). We conclude with suggestions for interpreting and conducting studies of the behavioral effects of prenatal hormones.

To assess the correlation between different cheiloscopic patterns with the terminal planes in deciduous dentition. Three hundred children who are 3-6 years old with complete primary dentition were recruited, and the pattern of molar terminal plane was recorded in the pro forma. Lip prints of these children were recorded with lipstick-cellophane method, and the middle 10 mm of lower lip was analyzed for the lip print pattern as suggested by Sivapathasundharam et al . The pattern was classified based on Tsuchihashi and Suzuki classification. Type II (branched) pattern was the most predominant cheiloscopic pattern. The predominant patterns which related to the terminal planes were as follows: Type IV (reticular) and Type V (irregular) pattern for mesial step, Type IV (reticular) pattern for distal step, and Type I (complete vertical) pattern for flush terminal plane. No significant relationship was obtained on gender comparison. Lip prints can provide an alternative to dermatoglyphics to predict the terminal plane in primary dentition. Further studies with larger sample size are required to provide an insight into its significant correlations.

Abstract To date, the known Chinese fauna of egg-parasitoids of the genus Oxyscelio Kieffer encompasses two species from the mainland – Oxyscelio doumao Burks and Oxyscelio nubbin Burks. Here we record eighteen species of Oxyscelio from collections in mainland China: Oxyscelio arvi Burks, Oxyscelio ceylonensis (Dodd), Oxyscelio convergens Burks, Oxyscelio cordis Burks, Oxyscelio crebritas Burks, Oxyscelio cuculli Burks, Oxyscelio dermatoglyphes Burks, Oxyscelio doumao Burks, Oxyscelio florus Kononova, Oxyscelio granorum Burks, Oxyscelio intermedietas Burks, Oxyscelio jugi Burks, Oxyscelio kramatos Burks, Oxyscelio longiventris Burks, Oxyscelio naraws Kozlov & Lê, Oxyscelio perpensus Kononova, Oxyscelio planocarinae Burks, and Oxyscelio striarum Burks. Oxyscelio is primarily found in the tropics, and most of these species are shared with Taiwan and southeast Asia. Three species previously known only from Japan, Oxyscelio arvi, Oxyscelio florus, Oxyscelio perpensus, are shared. The Chinese species are recorded from Guangdong, Guangxi, Hainan, Hebei, Hunan, Shaanxi, Sichuan, Yunnan and Zhejiang as well as additional material from Taiwan. Heptascelio hamatus Masner & Johnson and Platyscelio pulchricornis Kieffer are both recorded from Hainan and Guangdong, as well as records of Platyscelio pulchricornis from Sarawak and Thailand.

Five phenotypic females in one family had the genotype 46,XY and all had gonadal germ cell tumours. Studies of the family pedigree suggest that this form of XY gonadal dysgenesis is inherited in an X linked recessive manner. G banding of elongated metaphase chromosomes from two subjects with XY gonadal dysgenesis and a female carrier showed no aberrations of the X chromosome. The titres of H-Y antigen in three girls with XY gonadal dysgenesis were in the male control range. Thus it appears that, in the X linked form, XY gonadal dysgenesis may be caused by a point deletion or mutation of a gene on the X chromosome, which controls the gonad specific receptor for the H-Y antigen. Studies of Xg blood groups were uninformative about linkage of Xg with the X borne gene causing the XY gonadal dysgenesis. Dermatoglyphic studies in the girls with XY gonadal dysgenesis and female carriers revealed high a-b palmar ridge counts and a tendency for the A mainline to terminate in the thenar area. Both of these features have been described in patients with Turner's syndrome.

Dermatoglyphics, the study of epidermal ridges on palm, sole, and digits, is considered as most effective and reliable evidence of identification. The fingerprints were studied in 300 Nepalese of known blood groups of different ages and classified into primary patterns and then analyzed statistically. In both sexes, incidence of loops was highest in ABO blood group and Rh +ve blood types, followed by whorls and arches, while the incidence of whorls was highest followed by loops and arches in Rh −ve blood types. Loops were higher in all blood groups except “A –ve” and “B –ve” where whorls were predominant. The fingerprint pattern in Rh blood types of blood group “A” was statistically significant while in others it was insignificant. In middle and little finger, loops were higher whereas in ring finger whorls were higher in all blood groups. Whorls were higher in thumb and index finger except in blood group “O” where loops were predominant. This study concludes that distribution of primary pattern of fingerprint is not related to gender and blood group but is related to individual digits. PMID:29593909

The glabrous skin on the flexor sides of hands and feet, compared to other integument regions, has thicker epidermis and more complex pattern of epidermal ridges, wherefore in microscopy is denominated as thick skin. The epidermis of this skin type has individually unique and permanent superficial patterns, called dermatoglyphics, which are maintained by regenerative potential of deep epidermal rete ridges, that interdigitate with adjacent dermis. Using light microscopy, we analyzed cadaveric big toes thick skin samples, described histology of deep epidermal ridges (intermediate, limiting, and transverse), and quantitatively evidenced their pattern of proliferation by immunohistochemical assessment of Ki67. Immunohistochemical distribution of Ki67 was confined to basal and suprabasal layers, with pattern of distribution specific for intermediate, limiting and transverse ridges that gradually transform within epidermal height. Deep epidermal ridges, interdigitating with dermal papillae, participate in construction of intricate epidermal base, whose possible role in epidermal regeneration was also discussed. Having a prominent morphology, this type of epidermis offers the best morphological insight in complexities of skin organization, and its understanding could challenge and improve currently accepted models of epidermal organization.

Developmental instability and schizotypy.

It has been suggested that evidence of developmental disturbance of cognition and lateralisation in schizophrenia can be best understood from the perspective of developmental stability (DS), an indicator of the extent to which an individual develops according to a specified ontogenic programme in the presence of environmental noise. Higher levels of fluctuating asymmetry (FA; the difference between right and left side of a quantitative morphological trait such as dermatoglyphics) are thought to reflect less DS. We examined this issue for dimensions of schizotypy. Associations between FA, measures of laterality and cognitive function on the one hand, and negative and positive dimensions of schizotypy on the other, were examined in a sample of 260 healthy adolescents aged 11.9-15.6years. FA was measured as a-b ridge count right-left differences. Neuropsychological measures yielded a general cognitive ability score and a frontal function score. Laterality was assessed with the Annett scale. Measures of psychosis proneness were normally distributed. Negative schizotypy was associated with more FA and lower general cognitive ability in a dose-response fashion. The association with FA was more apparent in boys. No associations existed with laterality or frontal function. The negative dimension of schizotypy may be associated with early developmental instability, resembling the pattern seen in the negative symptom dimension of schizophrenia. Measures of fluctuating asymmetry may be more sensitive with regard to the schizotypy phenotype than measures of laterality.

We evaluated placentation effects on behavioral resemblance of 44 pairs of monozygotic (MZ) twin children. Tested at ages 4-6, the twins' zygosity and placental type had been determined at their delivery. The sample included 23 monochorionic (MC) and 21 dichorionic (DC) MZ twin pairs: DC-MZ twins result from separation of blastomeres within 72 h of ovulation; MC-MZ twins arise from later duplication of the inner cell mass. Twins were individually administered the McCarthy Scales of Cognitive Ability, while their mothers separately rated each cotwin on an individualized 280-item form of the Personality Inventory for Children (PIC). Absolute differences between MC-MZ cotwins were smaller than those between DC-MZ cotwins for all 20 PIC scales, significantly so for 3 of 4 factor scales, 8 of 12 clinical scales, and 2 of 4 validity/screening scales from the PIC; in contrast, no consistent differences in intrapair resemblance of mono- and dichorionic MZ twins were found for the McCarthy Scales. The chorion differences found in the PIC data cannot be due to genetic differences, because all pairs are monozygotes; nor are they associated with differences in parity, gestational age, birth weight, maternal education, palmar dermatoglyphic asymmetry, or maternal knowledge of chorion type. We interpret our findings as suggestive evidence that variation in timing of embryological division, with effects on MZ twins' placental vasculature, has significant consequences for some dimensions of their behavioral development, as well.

Parental Dermatoglyphics in Down's Syndrome. A Ten-year Study

Fathers and mothers of Down's syndrome cases show dermal microsymptoms when a large series of parents are compared to the general population. A Walker dermal index score in the overlap range (-2·99 to +3·00) is more likely to occur in fathers of age-dependent Down's syndrome cases (mean paternal age 40, range 25 to 54 years) and in Down's syndrome mothers than in the general population. The relative risk for these fathers to have a dermal index in the overlap range is two times the risk for male controls; the corresponding risk for mothers of Down's syndrome cases is 1·6 times that for female controls. Thus a score in the overlap range may be used to indicate a group of parents at higher risk for recurrence and occurrence of trisomy 21 offspring. This higher risk parent group can be offered cytogenetic studies, including amniocentesis and chromosome analysis on peripheral blood and skin, as dictated by clinical circumstances. From a comparison of dermal indexes in these studies, the contribution of maternal mosaicism to all cases of Down's syndrome is estimated to be about 11% and the contribution of paternal mosaicism about 8%. The contribution from mosaicism in the father but not in the mother appears to increase with parental age. To confirm these estimates, more parents with trisomy 21 mosaicism and trisomy 21 offspring must be diagnosed and studied quantitatively for dermal microsymptoms. PMID:4272738

To study the correlation between fingerprints and body size indicators in adulthood. Samples were composed of twins from two sub-registries of Chinese National Twin Registry (CNTR), including 405 twin pairs in Lishui and 427 twin pairs in Qingdao. All participants were asked to complete the field survey, consisting of questionnaire, physical examination and blood collection. From the 832 twin pairs, those with complete and clear demographic prints were selected as the target population. Information of Fingerprints pixel on the demographic characteristics of these 100 twin pairs and their related adulthood body type indicators were finally chosen to form this research. Descriptive statistics and mixed linear model were used for data analyses. In the mixed linear models adjusted for age and sex, data showed that the body fat percentage of those who had arches was higher than those who did not have the arches (P = 0.002), and those who had radial loops would have higher body fat percentage when compared with ones who did not (P = 0.041). After adjusted for age, there appeared no statistically significant correlation between radial loops and systolic pressure, but the correlations of arches (P = 0.031)and radial loops (P = 0.022) to diastolic pressure still remained statistically significant. Statistically significant correlations were found between fingerprint types and body size indicators, and the fingerprint types showed a useful tool to explore the effects of uterine environment on health status in one's adulthood.

Limbal palisades of Vogt.

PubMed Central

Goldberg, M F; Bron, A J

1982-01-01

The palisades of Vogt are distinctive normal features of the human corneoscleral limbus. Our clinical studies indicate that they are more discrete in younger and in more heavily pigmented individuals, and that they appear more regular and prominent at the lower limbus than at the upper limbus. They are seen only infrequently in the horizontal meridian. There is some symmetry (though it is not exact) from one eye to the other in the same person. The anatomy of the palisades appears to be unique for a given individual. In this respect, as well as in their microscopic anatomy, the palisades of Vogt appear comparable to fingerprints, and the term "conjunctivoglyphics" ("conjunctival carvings") or "limboglyphics" is suggested in analogy with "dermatoglyphics." The palisades of Vogt have a distinct vasculature with narrow, barely visible, arterial and venous components of radially oriented hairpin loops. Angiography reveals that these vessels leak fluorescein relatively late and only to a moderate extent. They respond to inflammation by dilatation and gross breakdown of their physiologic barrier properties. The functions of the palisades of Vogt are not known with certainty, but their interpalisadal epithelial rete ridges may serve as a repository for corneal epithelial cells. They may thus be important in both aging and diseases of the cornea.

Background Kabuki syndrome (KS) is a multiple congenital anomaly syndrome characterized by specific facial features, mild to moderate mental retardation, postnatal growth delay, skeletal abnormalities, and unusual dermatoglyphic patterns with prominent fingertip pads. A 3.5 Mb duplication at 8p23.1-p22 was once reported as a specific alteration in KS but has not been confirmed in other patients. The molecular basis of KS remains unknown. Methods We have studied 16 Spanish patients with a clinical diagnosis of KS or KS-like to search for genomic imbalances using genome-wide array technologies. All putative rearrangements were confirmed by FISH, microsatellite markers and/or MLPA assays, which also determined whether the imbalance was de novo or inherited. Results No duplication at 8p23.1-p22 was observed in our patients. We detected complex rearrangements involving 2q in two patients with Kabuki-like features: 1) a de novo inverted duplication of 11 Mb with a 4.5 Mb terminal deletion, and 2) a de novo 7.2 Mb-terminal deletion in a patient with an additional de novo 0.5 Mb interstitial deletion in 16p. Additional copy number variations (CNV), either inherited or reported in normal controls, were identified and interpreted as polymorphic variants. No specific CNV was significantly increased in the KS group. Conclusion Our results further confirmed that genomic duplications of 8p23 region are not a common cause of KS and failed to detect other recurrent rearrangement causing this disorder. The detection of two patients with 2q37 deletions suggests that there is a phenotypic overlap between the two conditions, and screening this region in the Kabuki-like patients should be considered.

Cri du Chat syndrome

Cerruti Mainardi, Paola

2006-01-01

The Cri du Chat syndrome (CdCS) is a genetic disease resulting from a deletion of variable size occurring on the short arm of chromosome 5 (5p-). The incidence ranges from 1:15,000 to 1:50,000 live-born infants. The main clinical features are a high-pitched monochromatic cry, microcephaly, broad nasal bridge, epicanthal folds, micrognathia, abnormal dermatoglyphics, and severe psychomotor and mental retardation. Malformations, although not very frequent, may be present: cardiac, neurological and renal abnormalities, preauricular tags, syndactyly, hypospadias, and cryptorchidism. Molecular cytogenetic analysis has allowed a cytogenetic and phenotypic map of 5p to be defined, even if results from the studies reported up to now are not completely in agreement. Genotype-phenotype correlation studies showed a clinical and cytogenetic variability. The identification of phenotypic subsets associated with a specific size and type of deletion is of diagnostic and prognostic relevance. Specific growth and psychomotor development charts have been established. Two genes, Semaphorin F (SEMAF) and δ-catenin (CTNND2), which have been mapped to the "critical regions", are potentially involved in cerebral development and their deletion may be associated with mental retardation in CdCS patients. Deletion of the telomerase reverse transcriptase (hTERT) gene, localised to 5p15.33, could contribute to the phenotypic changes in CdCS. The critical regions were recently refined by using array comparative genomic hybridisation. The cat-like cry critical region was further narrowed using quantitative polymerase chain reaction (PCR) and three candidate genes were characterised in this region. The diagnosis is based on typical clinical manifestations. Karyotype analysis and, in doubtful cases, FISH analysis will confirm the diagnosis. There is no specific therapy for CdCS but early rehabilitative and educational interventions improve the prognosis and considerable progress has been made in the social adjustment of CdCS patients.

Ponnudurai, R.; Jayakar, J.

2015-01-01

Summary: Dermatoglyphic traits which are reported to be largely determined by genes could be considered as phenotypic characterestics and if the same are expressed through generations in schizophrenic families it can be speculated to serve as genetic markers for schizophrenia. Another factor that might be influenced by genes is the age of onset of the illness in the offspring and the parent of origin. Objective: This study was aimed to elucidate the occurrence of identical finger patterns in the schizophrenic patients and their affected parents. The other objective was to assess the age of onset of the illness in them. Methods: Forty six schizophrenic patients in whom one of the parents was also affected with schizophrenia or related disorders were recruited. Of these pairs 29 were taken up for finger patterns analysis, with an equal number of control group pairs. 35 proband and parent pairs were investigated for the age of onset of the illness. Results: The frequency of occurrence of identical patterns in the right thumbs of proband and their affected mother pairs was significantly more than between the proband and their affected father pairs. Additionally, the number of identical patterns was also more in the right thumbs of proband and their affected mother pairs compared with the control group. The difference between the mean age of onset of the illness in the probands and their affected fathers was more than between the probands and their affected mothers. Conclusion: The genetic association of schizophrenic patients with the affected maternal side appear to be more stronger than with the paternal side. PMID:25657454

The paper deals with the distribution of genetic markers (systems ABO, MN, Rh (D), Hp, PTC) and a number of demographic (folding of arms, hand clasping, tongue rolling, right- and left-handedness, of the type of ear lobe, of the types of dermatoglyphic patterns) in the inhabitants of 6 villages in the Mezen District of the Archangelsk Region of the RSFSR (river Peosa basin). The data presented in this work were obtained in the course of examination of over 800 persons. Differences in the interpretation of the results of generally adopted methods of statistical analysis of samples from small populations are discussed. Among the systems analysed in one third of all the cases there was a statistically significant deviation from Hardy-Weinberg's ratios. For the MN blood groups and haptoglobins this was caused by the excess of heterozygotes. The test of Hardy--Weinberg's ratios at the level of two-loci phenotypes revealed no statistically significant deviations either in separate villages or in all the villages taken together. The analysis of heterogeneity with respect to markers inherited according to Mendel's law revealed statistically significant differences between villages in all the systems except haptoglobins. A considerable heterogeneity in the distribution of family names, the frequencies of some of them varying from village to village from 0 to 90%. Statistically significant differences between villages were shown for all the anthropogenetic characters except arm folding, hand clasping and right-left-handedness. Considering the uniformity of the environmental pressure in the region examined, the heterogeneity of the population studied is apparently associated with a random genetic differentiation (genetic drift) and, possibly, with the effect of the progenitor.

Background Fetal programming of diabetes might originate in early pregnancy when fingerprints are permanently established. The mean dermatoglyphic ridge count difference between fingertips 1 and 5 (‘Md15’) varies with the early prenatal environment. We hypothesized that Md15 would be associated with adult-onset diabetes. Methods We obtained Md15 from 577 Dutch adults (aged 58.9 years, SD 1.1) whose births in 1943–47 were documented in maternity records and from 260 of their same-sex siblings for whom birth weights were not available. Of these 837 participants, complete anthropometry and diabetes status (from history or glucose tolerance test) were obtained for 819. Results After adjustment for age, sex, parental diabetes and adult anthropometry, fingerprint Md15 was associated with prevalent diabetes [odds ratio (OR) = 1.37 per 1 SD (95% confidence interval 1.02–1.84)]. This relationship held [OR = 1.40 (1.03–1.92)] for diabetic cases restricted to those recently diagnosed (within 7 years). In the birth series restricted to recently diagnosed cases, the mutually adjusted ORs were 1.34 (1.00–1.79) per SD of Md15 and 0.83 (0.62–1.10) per SD of birth weight. Further adjustments for maternal smoking, conception season or prenatal famine exposure in 1944–45 did not alter these estimates. Among 42 sibling pairs discordant for diabetes, the diabetic sibling had higher Md15 by 3.5 (0.6–6.3) after multivariable adjustment. Conclusions Diabetes diagnosed at age 50+ years was associated with a fingerprint marker established in early gestation, irrespective of birth weight. Fingerprints may provide a useful tool to investigate prenatal developmental plasticity. PMID:18684786

Background and Objective: Forensic dentistry plays a vital role in detection and resolution of crime, civil proceedings and personal identification. With ever-increasing demands placed upon law enforcement to provide sufficient physical evidence linking a perpetrator to a crime, it makes sense to utilize any type of physical characteristic to identify a suspect of an offense. The least invasive and cost-effective procedure among all methods of human identification is the study of lip prints and fingerprints. This study is done to determine the predominant pattern of fingerprint and lip print in males and females and to correlate it for gender identification. Materials and Methods: The study sample comprised 100 individuals (50 males and 50 females) aged between 20 and 50 years; dark-colored lipstick was applied uniformly on the lips. The glued portion of cellophane tape was dabbed first in the center and then pressed uniformly over the corner of lips. Cellophane tape was then stuck to a white chart sheet for the purpose of permanent record. Lip print patterns were analyzed following the classification of Suzuki and Tsuchihashi. The imprint of left thumb was taken on a white chart sheet using a blue ink stamp pad and visualized using magnifying lens. Fingerprints were analyzed by following the classification given by Kücken. Correlation of lip print and fingerprint was analyzed using Chi-square test. Results: The overall correlation of lip prints with fingerprints in males revealed branched lip pattern associated with whorl fingerprint and in females as vertical lip print pattern associated with loop fingerprint. Conclusion: We conclude that the study between lip print and fingerprint can aid in gender determination. PMID:29386811

Fingerprints are considered to be one of the most reliable methods of identification. Identification of an individual plays a vital part of any medico-legal investigations. Dermatoglyphics is a branch of science that studies epidermal ridges and ridge patterns. Epidermal ridges are polygenic characteristics that form intrauterine 10-18 weeks and considered fully developed by the sixth month of fetal growth. Fingerprints are permanent morphological characteristics and criminal detection based on fingerprints is based on the principle that no two people can have identical fingerprints. Sex determination from fingerprints has been examined in different population. In this study we aimed to study fingerprint ridge density in Turkish population sample of Baskent University students. Fingerprints were obtained from 118 women, 88 men a total of 206 students aged between 17 and 28 years old by means of simple inking method. Fingerprints from all right and left hands fingers were collected in three different area of each. The ridges on fingerprints were counted diagonally on squares measuring 5 mm × 5 mm on radial, ulnar and inferior areas. The fingerprint ridge density in radial, ulnar and inferior areas and between sexes was compared statistically Mann Whitney U test and Friedman test. The ridge density was significantly greater in women in every region studied and in all fingers when compared to men. The fingerprint ridge density in the ulnar and radial areas of the fingerprints was significantly greater than the lower area. Fingerprint ridge density can be used by medico-legal examination for sex identification. Copyright © 2015 Elsevier Ltd and Faculty of Forensic and Legal Medicine. All rights reserved.

Identical anomalies produced by different causes such as aneuploidy, gene mutation, teratogenic chemicals, and certain surgical procedures are a clear indication that embryonic primordia respond as units in the production of developmental anomalies of anatomic structure. Hence, they must also act as units during normal ontogeny. The presence of identical malformations in different mammalian species identifies developmental and anatomic homology by virtue of descent from a common ancestor. These dys- and orthomorphogenetically reactive units are the equivalents of the classic experimental embryologist's epimorphic fields, which are those units of the embryo in which the development of complex structures appropriate to the species is determined and controlled in a spatially coordinated, temporarily synchronous, and epimorphically hierarchical manner that expresses both species-nonspecific (that is, phylogenetic) and species-specific genetically coded developmental information. Thus, it is as important for pathologists as it is for clinical geneticists to steep themselves in the art and science of phenotype analysis and to be able to do all of those studies, including anthropometry, dermatoglyphics, and growth analysis, that are required to arrive at inferences of cause and pathogenesis from the phenotype. There is probably one other incentive besides the ethical and intellectual ones to do this and to do it as well as possible, namely, the medico-legal consequences. If pathologists fail to illuminate the causal genesis of a given case to aid in preventing recurrence, then, in short order, they might be held equally as liable as clinicians for missing high recurrence risk genetic diagnoses. These depressing considerations aside, it is important to close on a positive note. As at the outset, we want to emphasize once more that, without question, this is the most exciting time to be working in the field of developmental pathology. In this specialty a marriage is occurring of several types of investigational methods, ranging from humble morphologic studies to metabolic analysis to the most sophisticated designs of molecular biology, to produce new interdisciplinary approaches to the solution of the oldest intellectual problem confronting medicine--how does the "fabric of the human body" (in the immortal words of Vesalius) come about?(ABSTRACT TRUNCATED AT 250 WORDS)

In recent times, some studies have explored the forensic application of dermatoglyphic traits such as the epidermal ridge breadth or ridge density (RD) toward the inference of sex and population from fingerprints of unknown origin, as it has been demonstrated that there exist significant differences of fingerprints between sexes and between populations. Part of the population differences found between these studies could be of methodological nature, due both to the lack of standardisation in the position of the counting area, as well as to the differences in the method used for obtaining the fingerprint. Therefore, the aim of this study was to check whether there are differences between the RD of fingerprints depending on where the counting area is placed and how the fingerprints are obtained. Fingerprints of each finger were obtained from 102 adult Spanish subjects (50 females and 52 males), using two methods (plain and rolled). The ridge density of each fingerprint was assessed in five different areas of the dactylogram: two closer to the core area (one on the radial and the other on the ulnar side), two closer to the outermost area of each of the sides (radial and ulnar), and another one in the proximal region of the fingertip. Regardless of the method used and of the position of the counting area, thumbs and forefingers show a higher RD than middle, ring, and little fingers in both sexes, and females present a higher RD than males in all areas and fingers. In both males and females, RD values on the core region are higher than those on the outer region, irrespective of the technique of fingerprinting used (rolled or plain). Regardless of the sex and location of the count area (core or outer), the rolled fingerprints exhibit RD greater than that of the plain ones in both radial and proximal areas, whereas the trend is inverted in the ulnar area, where rolled fingerprints demonstrate RD lesser than that of the plain ones. Therefore, in order for the results of different studies to be comparable, it is necessary to standardise the position of the count area and to use the same method of obtaining the fingerprint, especially when involving a forensic application.

We analysed scale morphology and micro-structure from five different body regions using scanning electron microscopy (SEM) across all nine recognized subgenera of the monitor lizard genus Varanus including 41 different species investigated. As far as we are aware, this qualitative visual technique was applied by us for the first time to most monitor lizard species and probably also to the primary outgroup and sister species Lanthanotus borneensis. A comprehensive list of 20 scalation characters each with up to seven corresponding character states was established and defined for the five body regions sampled. For the phylogenetic approach, parsimony analyses of the resulting morphological data matrix as well as Bremer and bootstrap support calculations were performed with the software TNT. Our results demonstrate that a variety of micro-ornamentations (i.e., ultra- or micro-dermatoglyphics) as seen in various squamate groups is hardly present in monitor lizards. In several species from six out of nine subgenera, however, we found a honeycomb-shaped micro-structure of foveate polygons. Two further samples of Euprepiosaurus Fitzinger, 1843 exhibit each another unique microscopic structure on the scale surface. Notably, the majority of species showing the honeycombed ultra-structure inhabit arid habitats in Australia, Africa and the Middle East. Therefore, it can be inferred that this microscopic scalation feature, which has also been identified in other desert dwelling lizard species, is taxonomically and ecologically correlated with a xeric habitat type in varanids, too. In addition, the systematic affiliation of V. spinulosus, an endemic monitor lizard species from the Solomon Islands with an extraordinary scale shape, is discussed in the light of current hypotheses about its phylogenetic position within the Varanidae. Due to its unique scalation characteristics, in combination with other morphological evidence, a new monotypic subgenus, Solomonsaurus subgen. nov., is erected for this enigmatic monitor lizard species. Furthermore, we propose a taxonomic splitting of the morphologically and ecologically heterogeneous subgenus Euprepiosaurus comprising the Pacific or mangrove and the tree monitor lizards, respectively, again based on the SEM data. Thus, for the members of the highly arboreal V. prasinus species group erection of a new subgenus, Hapturosaurus subgen. nov., is justified based on the autapomorphic scale shape in concert with further morphological, phylogenetic and ecological evidence. In addition, V. reisingeri originally described as a distinct species is considered conspecific with the wide-spread V. prasinus due to joint synapormorphic features in the ventral scale micro-structure. Consequently, V. prasinus is (again) rendered polytypic with the taxon reisingeri being assigned subspecies status here.        In conclusion, the established scalation characters allow discrimination of single species even among closely-related Varanus species, such as the members of the V. indicus species group. Together with a recently published identification key for Southeast Asian monitor lizards based on macroscopic phenotypic characters (Koch et al. 2013), the SEM-pictures of the present study may serve as additional references for the microscopic identification of CITES-relevant monitor lizard skins and products, respectively.

Neotypes are designated for nine species, including the type species O. foveatus Kieffer, Oxyscelio brevinervis (Kieffer), Oxyscelio bifurcatus (Kieffer), Oxyscelio frontalis (Kieffer), Oxyscelio crassicornis (Kieffer), Oxyscelio cupularis (Kieffer), Oxyscelio foveatus Kieffer, Oxyscelio kiefferi Dodd, Oxyscelio magnus (Kieffer) and Oxyscelio marginalis (Kieffer). Oxyscelio bifurcatus (Kieffer) syn. n. and Oxyscelio frontalis (Kieffer) syn. n. are synonymized under Oxyscelio consobrinus (Kieffer). The fauna is divided into 13 species groups, with six species unplaced to a group. A phylogenetic analysis employing 73 morphological characters did not find most of these groups to be monophyletic, but they are retained to aid in specimen identification. Potential biogeographical patterns are discussed, including regional variation in surface sculpture and a morphological link between Sri Lankan and Australian species. PMID:23794863
