Primer-engineered multiplex PCR-RFLP for detection of MTHFR C677T, prothrombin G20210A and factor V Leiden mutations

Abstract

Single-nucleotide polymorphisms in the genes that code for coagulation factors V (factor V Leiden) and II (prothrombin, G20210A), as well as the methylenetetrahydrofolate reductase (MTHFR, C677T) gene, have been implicated in the majority of cases of hereditary thrombophilia. We have developed a multiplex PCR-RFLP assay based on MnlI endonuclease digestion for the simultaneous detection of mutations in the FV, FII, and MTHFR genes. Digested amplification products were analyzed by gel electrophoresis in a single gel lane and visualized by ethidium bromide. This approach is a rapid and convenient method, hence economic, that alternate to others described for the detection of FVL, G20210A and C677T mutations.
