title: Determination of Methylenetetrahydrofolate Reductase (MTHFR) gene polymorphism in Turkish patients with nonsyndromic cleft lip and palate.
abstract: OBJECTIVE
  To investigate the association between MTHFR C677T polymorphism and Turkish patients with nonsyndromic cleft lip and/or palate (nsCL/P) and to determine the prevalence of the Turkish population.
  
  
  METHODS
  Molecular analysis of gene polymorphisms were carried out using polymerase chain reactions and restriction enzyme digestions. In our study, 80 patients with nsCL/P and 125 unrelated individuals from Turkey were studied.
  
  
  RESULTS
  We found that MTHFR C677T polymorphism is a significant risk factor for nsCL/P in Turkey (p=0.0004). These results support the impact of MTHFR C677T polymorphism and importance of folic acid intake in the etiology of nsCL/P.
  
  
  CONCLUSIONS
  MTHFR gene which is localized in the relevant region of chromosome 1p36.3 not been studied Turkish patients with nsCL/P and the prevalence of our country not to be determined. We revealed statistically association between the MTHFR C677T gene polymorphism and nonsyndromic cleft lip and/or palate in the Turkish population.
