- Abstract
- Methylenetetrahydrofolate reductase (MTHFR) is a key enzyme involved in folate metabolism, DNA methylation and synthesis. We investigated the association between MTHFR polymorphisms and the risks of acute and chronic leukaemias. MTHFR C677T and A1298C were genotyped in 396 Korean individuals using multiplex polymerase chain reaction/restriction fragment-length polymorphism. They were acute lymphoblastic leukaemia (ALL, n = 89), acute myeloid leukaemia (AML, n = 55), biphenotypic acute leukaemia (n = 12), chronic myelogenous leukaemia (CML, n = 40), and normal controls (n = 200). C677T genotypes were not associated with the risk of each disease. A1298C variants, however, significantly decreased the risks of ALL and CML compared with 1298AA. Odds ratios and 95% confidence intervals of 1298AC and 1298AC + CC were 0.53 (0.31-0.93) and 0.54 (0.31-0.93) in ALL, and 0.34 (0.14-0.80) and 0.40 (0.18-0.89) in CML, respectively, compared with 1298AA. These findings demonstrate that the development of ALL and CML is more dependent on folate status, and more susceptible to DNA instability than that of AML. In addition, A1298C rather than C677T may be a more important genetic risk modifier in leukaemogenesis at least in the Korean population.
