Etiology

Prothrombin, also known as Factor II (FII), is a protein involved in the blood clotting mechanism. The autosomal recessive G20210A mutation present in the 3'-untranslated region of FII leads to increased translation of the protein and thus increased risk of hypercoagulability disorders or thrombophilia1-4.

Factor V Leiden (FVL) is the most common hereditary factor V (FV) variant of coagulation, which prevents FV inactivation by protein C, thus increasing the risk of blood thrombus formation1-4.

Methylenetetrahydrofolate reductase (MTHFR) is involved in amino acid metabolism. Mutations (C677T and A1298C) leading to reduced activity of this enzyme are associated with increased levels of homocysteine in the blood. It is believed that this may be associated with the onset of several diseases, including vascular occlusive disease and homocystinuria1-4.

Epidemiology

The G20210A mutation of FII is the second most frequent variant implicated in hypercoagulability disorders in the Caucasian population with a prevalence of 1% to 4%, while FV Leiden is the most common variant with a frequency of 3-5% and 20-40% in patients with venous thromboembolic disease. Heterozygosity and homozygous mutation of FV increase the probability of thrombosis up to 10- and 100-fold, respectively1-4.
