TAR patients are missing one of the two bones from each lower arm. The missing bone is called the radius, and it runs from the elbow to the wrist on the side of the thumb. The thumbs are not missing, as they are in some of the other bone marrow failure disorders (see Fanconi anemia, Diamond-Blackfan anemia).

Aim:? Thrombocytopenia-absent radius (TAR) syndrome is characterised by bilateral absence of the radii in the presence of both thumbs and hypomegakaryocytic thrombocytopenia. We report our experience of three patients affected by TAR syndrome presenting with different clinical manifestations focusing on the ...

BackgroundThrombocytopenia and absent radius syndrome (TAR) is a rare genetic disorder. It is an autosomal recessive disorder characterised by radial aplasia and thrombocytopenia that may have additional anomalies. We report a case of TAR syndrome with crossed fused renal ectopia. This anomaly has not been previously reported in ...

Transverse Aeolian Ridges (TARs), 10 m scale, ripple-like aeolian bedforms with simple morphology, are widespread on Mars but it is unknown what role they play in Mars� wider sediment cycle. We present the results of a survey of all Mars Global Surveyor Narrow angle images in a pole-to-pole study area, 45� longitude wide.Following on from the classification scheme and ...
