Popis: Base excision repair (BER) is the main mechanism to repair endogenous DNA lesions caused by reactive oxygen species. BER deficiency is linked with cancer susceptibility and premature aging. Single nucleotide polymorphisms (SNPs) within BER genes have been implicated in various human malignancies. Nevertheless, a comprehensive investigation of their association with Wilms tumor susceptibility is lacking. In this study, 145 cases and 531 sex and age-matched healthy controls were recruited. We systematically genotyped 18 potentially functional SNPs in six core BER pathway genes, using a candidate SNP approach. Logistic regression was employed to evaluate odds ratio (OR) and 95% confidence interval (CI) adjusted for age and gender. Several SNPs showed protective effects against Wilms tumor. Significant associations with Wilms tumor susceptibility were shown for hOGG1 rs1052133 (dominant: adjusted OR = 0.66, 95% CI = 0.45–0.96, P = .030), FEN1 rs174538 (dominant: adjusted OR = 0.66, 95% CI = 0.45–0.95, P = .027; recessive: adjusted OR = 0.54, 95% CI = 0.32–0.93 P = .027), and FEN1 rs4246215 (dominant: adjusted OR = 0.55, 95% CI = 0.38–0.80, P = .002) polymorphisms. Stratified analysis was performed by age, gender, and clinical stage. Moreover, there was evidence of functional implication of these significant SNPs suggested by online expression quantitative trait locus (eQTL) analysis. Our findings indicate that common SNPs in BER genes modify susceptibility to Wilms tumor.
Highlights • Numerous studies demonstrated association between BER gene SNPs and cancer susceptibility. However, the linkage between BER SNPs and Wilms tumor susceptibility has not been reported. We investigated 18 BER gene SNPs in 145 Wilms tumor cases and 531 healthy controls. Significant associations with decreased Wilms tumor susceptibility were observed for the hOGG1 rs1052133, FEN1 rs174538, and rs4246215 polymorphisms. eQTL analysis suggested potential functional implications for the significant polymorphisms. This is the most comprehensive investigations on the association between the BER polymorphisms and Wilms tumor susceptibility. Our findings support the potential protective role of these SNPs in Wilms tumor.
