Prothrombin thrombophilia is an inherited disorder of blood clotting. Thrombophilia is an increased tendency to form abnormal blood clots in blood vessels. People who have prothrombin thrombophilia are at somewhat higher than average risk for a type of clot called a deep venous thrombosis, which typically occur in the deep veins of the legs. Affected people also have an increased risk of developing a pulmonary embolism. However, most people with prothrombin thrombophilia never develop abnormal blood clots. Prothrombin thrombophilia is the second most common inherited form of thrombophilia after factor V Leiden thrombophilia. It is more common in Caucasian populations. This condition is caused by a particular mutation (written G20210A or 20210G>A) in the F2 gene. People can inherit one or two copies of the gene mutation from their parents.[1]
