Thrombocytopenia and absent radius syndrome (TAR) is a rare genetic disorder which is inherited as an autosomal recessive trait. This disorder is characterized by low levels of platelets in blood (thrombocytopenia) resulting in potentially severe bleeding episodes primarily during infancy. Other characteristic findings include bilateral radial aplasia. Other abnormalities may also be present such as defects of hands, structural malfunctions of the heart and kidneys.
