Methylenetetrahydrofolate reductase C677T and A1298C polymorphism and susceptibility to acute lymphoblastic leukemia in a cohort of Egyptian children

Abstract

This case–control study was planned to investigate the possible role of methylenetetrahydrofolate reductase (MTHFR) C677T and A1298C polymorphisms as a risk factor for the development of acute lymphoblastic leukemia (ALL) in a cohort of Egyptian children. Typing of MTHFR C677T and A1298C polymorphisms was done using restriction fragment length polymorphism (RFLP) for 100 children with ALL and 100 age- and sex-matched healthy controls. No significant differences were found between patients with ALL and controls for the frequency of MTHFR C677T and A1298C alleles, genotypes, combined genotypes or haplotypes. The C677T and A1298C genotype frequency was different from that in Korean and Chinese populations (p < 0.5) and was similar to that in British, French-Canadian and German-Caucasian populations (p > 0.5). Our findings suggest that MTHFR C677T and A1298C polymorphisms are unlikely to affect the development of childhood ALL in an Egyptian population from Delta.
