بررسی ارتباط چند شکلیهاي فاکتور (G1691A ( V و فاکتور(G20210A (II با سندرم سقط مکرر جنین در بیماران ایرانی

Background: The pathogenesis of recurrent pregnancy loss includes complex interaction of several genetic and environmental factors. Changes in blood coagulation factors during pregnancy may play an important role in the occurrence of recurrent abortions (RA). Recently, inherited thrombophilia has been considered as a possible cause. Therefore, in this study we have investigated association of factor V (G1691A) and factor II (G20210A) polymorphisms in Iranian patients with recurrent abortions. Materials and Methods: A total of 203 women participated in this study: 105 women with two or more consecutive unexplained miscarriage as cases and 98 women with at least two healthy children as control group. Total genomic DNA was isolated from Peripheral blood leukocytes. The presence or absence of mutation in the FV (G1691A) and FII (G20210A) polymorphisms were assessed by PCR-RFLP, using Mnl1 and HindIII digestion enzymes, respectively. Finally, data was analyzed using Chi-Square(χ 2 ) test. Results: The results showed no statistical significant differences in the prevalence of FV (G1691A) and FII (G20210A) polymorphisms between patients and control group. Conclusion: considering the results of this study, these polymorphisms Seem to have no role in etiology of recurrent pregnancy loss in the studied population. [ABSTRACT FROM AUTHOR]
