Prothrombin (Factor II) is the precursor of the serine protease thrombin, a key enzyme in the process of hemostasis and thrombosis, that exhibits procoagulant, anticoagulant and antifibrinolytic activities. One nucleotide change in the prothrombin gene – F2 c.*97G>A (rs1799963; g.46761055G>A; NC_000011.9; NM_000506.3; commonly referred to as 20210G>A), is associated with elevated prothrombin levels, an increased risk of venous thromboembolism and recurrent thromboembolism. Other genetic as well as environmental factors may also influence the risk of thrombosis. Genetic counseling may be indicated.
