Clinical Significance
Prothrombin (Factor II) 20210G>A Mutation Analysis - Factor II Mutation (G20210A) is one of the most common causes of venous thrombosis. 2.3% of the general population is heterozygous in contrast with 6.2% of patients with venous thrombosis and 18% with familial venous thrombosis. Other risk factors compound the risk for venous thrombosis.
