The Factor II (Prothrombin) G20210A mutation is the second most common genetic abnormality of the coagulation system, after Factor V Leiden, and is associated with elevated plasma prothrombin levels and increased risk of venous thrombosis. This mutation is present in 18% of patients with family history of venous thrombosis and more than 6% of patients with deep venous thrombosis. Heterozygous individuals with this mutation have an approximately 3-fold increased risk of venous thrombosis. Other predisposing factors include pregnancy related venous thrombosis, intrauterine growth retardation, preeclampsia, and unexplained fetal loss (N Engl J Med. 2001 Apr 19;344(16):1222-31). Homozygosity for this mutation is very rare and the increased risk for these individuals is not known.
