Congenital antithrombin III deficiency is mainly due to the inheritance of the defective genes in the blood of the patient. This defective gene is passed on from the genes of the affect parent. The presence of this defective gene may lead to production of low levels of antithrombin III in the blood of the patient. The deficiency of the antithrombin III factor is also due to less production of certain enzymes that may directly affect the production of antithrombin III in the blood of the patient. Liver disease, intake of certain medicines, such as L-asparaginase, etc, may also lead to this disease.
