Factor II Prothrombin (gene G20210A)

About this test

Factor II Prothrombin mutation G20210A is a common genetic risk factor for thrombosis including deep venous thrombosis, DVT.

This mutation in the gene G20210A encoding the clotting factor prothrombin is found in about 1 in 50 persons in the UK.

A mutation in the gene G20210A raises the risk of thrombosis significantly for both males and females in all age groups.

Testing for prothrombin mutation G20210A is useful in determining a person's predisposition to thrombosis and can assist in determining the need for anticoagulant therapy.

People who have prothrombin mutation G20210A have a 2-to-3 fold increase in the risk of DVT.

Persons who have this mutation plus the Factor V Leiden mutation have a 10-to-20 fold increase in thrombotic risk.

Prothrombin mutations have also been linked with thrombotic events other than DVT, including recurrent miscarriage (repeat spontaneous abortions). In addition, there may be interactions with other risk factors for thrombosis, including pregnancy, the use of oral contraceptives, and immobilisation.
