We retrospectively evaluated the association of the MTHFR 677C>T and 1298A>C polymorphisms with pediatric ALL by genotyping a study sample of 443 ALL patients consecutively enrolled onto the German multicenter trial ALL-BFM 2000 and 379 healthy controls.
These results do not support the suggestion that populations carrying different genotypes of the two MTHFR polymorphisms, C677T and A1298C, have a different susceptibility to ALL, at least in the Mediterranean area.
In a case-control study, we evaluated whether four common polymorphisms in methylenetetrahydrofolate reductase (MTHFR C677T and A1298C), methionine synthase (MS A2756G), and methionine synthase reductase (MTRR A66G) genes may have a role in altering susceptibility to adult acute lymphoblastic leukemia (ALL) and non-Hodgkin's lymphoma (NHL).
We previously reported that 2 polymorphisms in the 5,10-methylenetetrahydrofolate reductase (MTHFR) gene at positions C677T and A1298C were associated with lower risk of adult acute lymphocytic leukemia (ALL).
