Abstract
The pathogenesis of glioma remains largely unknown now. It has been suggested that the X-ray cross-complementing group 1 (XRCC1) gene may influence the capacity to repair DNA damage leading to an increased gliomas susceptibility. This study aimed to evaluate the relationship between XRCC1 polymorphisms and glioma risk. Genotypes were assessed in 368 Chinese glioma patients and 346 healthy controls. XRCC1 Arg194Trp (rs1799782), Arg280His (rs25489) and Arg399Gln (rs25487) and three additional polymorphisms were directly sequenced. The frequency of Arg280His A allele was significant lower in glioma group than in healthy controls [9.6 vs 16 %, OR = 0.60 (0.46–0.80), P < 0.001]; the frequencies of GA or AA genotypes were different in two groups (16.6 vs 22.8 %, 1.3 vs 4.7 %). The frequency of Arg399Gln A allele was significant higher in glioma group than in healthy controls [38.7 vs 30.1 %, OR = 1.29 (1.11–1.49), P = 0.001]; the frequencies of GA or AA genotypes were different in two groups (45.4 vs 38.2 %, 16 vs 10.9 %). This study demonstrates that the rs25489 (Arg280His) and Arg399Gln (rs25487) polymorphisms in XRCC1 gene might influence the risk of developing glioma in Chinese population.
