title: Thrombophilic genes alterations as risk factor for recurrent pregnancy loss.
abstract: OBJECTIVE
  The important polymorphisms leading to inherited thrombophilia are Factor V Leiden (FVL), Prothrombin G20210A and MTHFR C677T and A1298C. The frequencies also the correlation among these polymorphisms and RPL have been reported controversially in various populations. Our clinic is one of the referral centers in reproductive biomedicine in which patients in all over Iran refer to; thus the results of this study could be considered clinically beneficial. Besides, in the present study, not only the frequency of specific but also multiple thrombophilic gene alterations were compared in Iranian women with RPL and a control group.
  
  
  METHODS
  The patients group comprised 330 women with three or more consecutive RPLs. The control population included 350 women with at least one child and no history of pregnancy loss. FVL, Prothrombin G20210A and MTHFR C677T polymorphisms were analyzed by Strip assay kit. MTHFR A1298C was genotyped by PCR-RFLP.
  
  
  RESULTS
  The frequencies of FVL, Prothrombin G20210A, MTHFR C677T and MTHFR A1298C mutations in patients were 8.48, 4.24, 45.45 and 59.39%, and in controls were 2.86, 2.86, 34.28 and 6%, respectively.
  
  
  CONCLUSIONS
  The present data showed that FVL, MTHFR polymorphisms also combined with thrombophilic gene mutations have a strong association with RPL.
