Effects of polymorphisms in nucleotide excision repair genes on glioma risk in a Chinese population.

We performed a case-control study to assess the relationship between six single nucleotide polymorphisms (SNPs) of xeroderma pigmentosum complementation group F (XPF) on glioma risk in a Chinese population. The six SNPs were genotyped in 330 glioma cases and 652 cancer-free controls using a 384-well plate format on the Sequenom MassARRAY platform (Sequenom, San Diego, USA). Rs1800067 did not follow the Hardy-Weinberg equilibrium in the control group, and the genotype distributions differed significantly between the two groups for SNPs rs1800067 and rs2276466. For rs1800067, the variant genotype T/T was strongly associated with an increased risk of glioma when compared with the A/A genotype (OR=3.77, 95% CI=2.38-6.01). Individuals with the rs1800067 G allele had a relatively high risk of glioma in a dominant model (OR=3.47, 95% CI=2.26-5.37). The rs2276466 G/G genotype was significantly associated with a moderate increased risk of glioma (OR=1.82, 95% CI=1.10-3.02) in a codominant model, and variation of rs25489 was associated with a 1.31- and 1.78-fold glioma risk in dominant and recessive models, respectively. Our study is the first to identify polymorphisms in rs1800067 and rs2276466 as correlated with glioma susceptibility.
