    Abstract:
    The present study investigated the association between genetic polymorphisms of selected thrombophilic factors with recurrent miscarriage (RM). The genetic polymorphisms for plasminogen activator inhibitor-1 4G/5G (PAI-1), Factor V Leiden (FVL), Factor II G20210A (FII) and methylenetetrahydrofolate reductase MTHFR C677T were determined in 186 RM women and 129 healthy women. In RM women, the frequency of heterozygosity for PAI-1 5G/4G (31%) was significantly higher than in controls (5G/4G: 22%) whereas no difference was found in the case of homozygosity 4G/4G and 5G/5G. The frequencies of genotype G/A for FVL and FII were significantly higher in RM women (FVL, 10%; FII, 8%) than in controls (FVL, 3%; FII, 2%). No difference was found in the case of MTHFR C677T. The polymorphisms of FVL and FII should be screened in RM women, whereas PAI-1 seems to be weakly associated with RM. The role of MTHFR C677T polymorphisms without hyperhomocysteinemia appears negligible.
