The OGG1 326 GG and BRCA1 871 TT genotypes were associated with a decreased risk for NHL (OROGG1 GG = 0.70, p = 0.008; ORBRCA1 TT = 0.71, p = 0.048), DLBCL (OROGG1 GG = 0.68, p = 0.02; ORBRCA1 TT = 0.62, p = 0.04), and T-cell lymphoma (OROGG1 GG = 0.59, p = 0.04; ORBRCA1 TT = 0.42, p = 0.04). This evidence concerns the gene OGG1 and non-Hodgkin lymphoma.
