ABSTRACT
Background: Recurrent pregnancy loss [RPL] is caused by different factors, including genetics and thrombophilia. Beside Factor V Leiden, another nucleotide change in a factor V [FV] gene [A4070G; His1299Arg] has been identified linking to hereditary thrombophilia. Also, two proposed MTHFR polymorphisms, C677T and A1298C [Glu429A] are linked with RPL
Objective: In this study, the effect of two factors, A4070G in FV and A1298C in MTHFR are evaluated in RPL patients from Mazandaran province, Iran
Materials and Methods: Sample population of 100 women with RPL and 100 controls with Mazandarani ethnics from northern Iran were consist. The factor V [A4070G] and MTHFR [A1298C] polymorphisms were genotyped by PCR-RFLP
Results: Molecular study showed 5 women from patients and 9 women from control group were heterozygous AG for A4070G. Frequency of "A" allele in patient and control groups was 97.5% [0.975] and 95.5% [0.955] respectively, and "G" allele frequency was 2.5% [0.025] and 4.5% [0.045] respectively. No significant association [p=0.05] between FV A4070G genotype and RPL with an OR=1.88, CI 95%=0.6-5.82, was observed [p=0.4]. Also, for A1298C, all patients and control individuals were AA genotype. "A" allele frequency in patients and control was 100% and "C" allele frequency was zero. There was no significant difference for A1298C between groups
Conclusion: Our finding showed that A4070G and A1298C polymorphisms cannot be considered as a cause of PRL in women from Mazandaran province, northern Iran
