title: The methionine synthase polymorphism c.2756A>G alters susceptibility to glioblastoma multiforme.
abstract: Genetic polymorphisms of methionine metabolism, in particular methionine synthase (MTR) c.2756A>G (D919G) and methylenetetrahydrofolate reductase (MTHFR) c.677C>T (A222V), have been associated with various human cancers. We investigated MTR c.2756A>G, MTHFR c.677C>T, and a third polymorphism, transcobalamin 2 c.776C>G (P259R), for a potential association with the formation of glioblastoma multiforme. The MTR c.2756G allele was significantly underrepresented among 328 glioblastoma multiforme patients of Caucasian origin when compared with 400 population controls [patients AA/AG/GG: 0.72/0.26/0.02 and controls AA/AG/GG: 0.57/0.38/0.05, degrees of freedom = 2; chi(2) = 17.86 (Pearson); P < 0.001]. No association between glioblastoma multiforme and the two other polymorphisms was observed.
