title: ACE and MTHFR gene polymorphisms in unexplained recurrent pregnancy loss.
abstract: OBJECTIVE
  To assess the association between polymorphisms in angiotensin converting enzyme and methylene tetrahydrofolate reductase genes and recurrent pregnancy loss by a case-control study in South Indian women.
  
  
  METHODS
  DNA was extracted from peripheral blood leukocytes of 104 women with Recurrent Pregnancy Loss (RPL) and 120 controls. Genotyping of ACE Insertion Deletion and MTHFR C677T polymorphism were carried out by PCR and PCR-RFLP, respectively.
  
  
  RESULTS
  No statistically significant difference was observed in the distribution of genotypes between cases and controls for ACE and MTHFR polymorphisms. Further, the combination of MTHFR and ACE genotypes failed to reveal an association.
  
  
  CONCLUSIONS
  In conclusion, the present study reveals lack of association of MTHFR C677T and ACE I/D polymorphisms in RPL in South Indian women. However, we cannot exclude the possibility that other polymorphisms of ACE and MTHFR genes could be associated with the disease and might be clinically useful as a marker to assess risk for RPL.
