General Discussion
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 common abnormalities are often present including additional skeletal defects such as absence or underdevelopment of the other bones of the forearm (ulnae), structural malformations of the heart (congenital heart defects), kidney (renal) defects. Affected individuals may be abnormally short for their age (short stature) and exhibit cow’s milk intolerance. TAR syndrome is believed to be inherited as an autosomal recessive trait. However, evidence suggests that inheritance in TAR syndrome may be more complex than simple recessive inheritance in some cases.
