C677T and A1298C methylenetetrahydrofolate reductase (MTHFR) polymorphisms have been suggested to affect susceptibility to malignant lymphoma, possibly by altering DNA methylation. The DNA repair gene O6-methylguanine DNA methyltransferase (MGMT) is transcriptionally silenced by promoter hypermethylation in diffuse large B-cell lymphomas (DLBCL). We analyzed the MTHFR677 and MTHFR1298 genotypes in 111 DLBCL patients and 465 controls. No significant difference in the frequency of MTHFR polymorphisms between patients and controls and no significant association between MTHFR677 or MTHFR1298 genotypes and methylation of MGMT promoter were observed. These results indicate that MTHFR variants are not related to DLBCL development and MGMT hypermethylation.
