Concomitant heterozygous factor V Leiden mutation and homozygous prothrombin gene variant (G20210A) in patient with cerebral venous thrombosis.

Background: Factor V Leiden mutation represents the most common genetic risk factor of venous thrombosis in Caucasian population. A common mutation in prothrombin gene, which is due to G-->A transition at position 20210, is also associated with elevated prothrombin concentration and thrombosis. Both this mutations may constitute concomitant risk factors for deep venous thrombosis.
