title: Association of the 5,10-methylenetetrahydrofolate reductase (MTHFR C677T and A1298C) polymorphisms in Korean patients with adult acute lymphoblastic leukemia.
abstract: BACKGROUND
  Methylenetetrahydrofolate reductase (MTHFR) plays a central role in converting folate to methyl donor for DNA methylation. Because MTHFR is a key enzyme in folate metabolism, changes in its activity resulting from polymorphisms in the MTHFR gene could modify the susceptibility to cancer. Recently, the C677T and A1298C mutations of MTHFR were discovered to be associated with susceptibility in acute lymphoblastic leukemia (ALL).
  
  
  METHODS
  The association between MTHFR polymorphisms and susceptibility and clinical outcome in ALL was studied in 118 adult ALL patients and matched healthy controls (n =427). DNA samples taken from patients with ALL and controls were analyzed using polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP) assays to detect the MTHFR C677T and A1298C mutations.
  
  
  RESULTS
  No significant difference was found in the development of adult ALL among those with different MTHFR genotypes of the C677T or A1298C polymorphisms. However, the MTHFR 677CT+TT genotype showed a tendency to be associated with adult ALL [crude odds ratio (OR), 0.67; 95% confidence interval (CI), 0.44-1.02; adjusted OR, 0.74 95% CI, 0.47-1.14].
  
  
  CONCLUSIONS
  The MTHFR C677T and A1298C polymorphisms are not significant risk factors in adult acute leukemia in the Korean population.
