Multiplex PCR-RFLP assay for detection of factor V Leiden and prothrombin G20210A

Factor V Leiden and prothrombin G20210A are clinically relevant genetic risk factors for venous thrombosis. Molecular diagnostic testing for factor V Leiden and prothrombin G20210A is widespread, and laboratories use a variety of technical approaches. Here we introduce a multiplex polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP) based on single (Mn/l) restriction endonuclease digestion. The assay was shown to simultaneously and accurately detect factor V Leiden and prothrombin G20210A mutations.
