Thrombocytopenia Absent Radius Syndrome
National Organization for Rare Disorders, Inc.
It is possible that the main title of the report Thrombocytopenia Absent Radius Syndrome is not the name you expected.
Thrombocytopenia-absent radius (TAR) syndrome is a rare disorder that is present at birth (congenital). It is characterized by low levels of platelets in the blood (thrombocytopenia) and absence (aplasia) of the long, thin bones of the forearms (radii). Other abnormalities are often present including additional skeletal defects such as absence or underdevelopment of the other bone of the forearm (ulna), structural malformations of the heart (congenital heart defects), and kidney (renal) defects. Affected individuals may be abnormally short for their age (short stature) and exhibit cow's milk intolerance. TAR syndrome is inherited as an autosomal recessive genetic disorder and caused by deletion and/or mutations in the RBM8A gene.
