Plasminogen activator inhibitor 1 and methylenetetrahydrofolate reductase gene mutations in iranian women with polycystic ovary syndrome.
Abstract
Problem
Mutations in genes related to thrombophilia and hypofibrinolysis have been associated with recurrent pregnancy loss (RPL) and polycystic ovary syndrome (PCOS).
Methods
Using PCR-RFLP, we investigated the frequencies of MTHFR (A1298C and C677T) as well as PAI-1 (-675 4G/5G) gene polymorphisms in 177 RPL and 100 control women. RPL women were stratified into 38 women with PCOS (RPL-PCOS), 33 with ovarian PCO (RPL-ovarian PCO), and 106 without PCOS (RPL).
Results
RPL, RPL-PCOS, and RPL-ovarian PCO groups showed significantly higher frequencies of MTHFR A1298C (P < 0.001) and PAI-1 4G/5G (P < 0.001) mutations than the controls. No significant differences were found between the RPL groups. The respective odds ratios (OR) for bearing MTHFR (A1298C, C677T) and PAI-1 (4G/5G) gene mutations were 33.9-, 2.2-, and 5.2-fold higher in RPL, 66.3-, 6.7-, and 2.8-fold higher in RPL-PCOS, and 27.3-, 1.9-, and 3.9-fold higher in RPL-ovarian PCO women than those in controls.
Conclusion
Our results showed the significance of MTHFR A1298C and PAI-1 4G/5G mutations in Iranian women suffering from RPL with and without PCOS.
