    Abstract:
    OBJECTIVE: To study the relationship between polymorphism of genes XPA, XPC, XPD, XRCC1 and susceptibility to acute lymphoblastic leukemia (ALL) in a Chinese population. METHODS: Polymorphism were determined by a case-control study through matrix-assisted laser desorption/ionization tandem time-of-flight mass spectrometry method of Mass-ASSAY platform in 114 confirmed ALL cases and 169 age- and sex-matched controls, so as to compare the relationship between different genotypes and ALL risk. RESULTS: Multivariate logistic regression analysis revealed that individuals carrying at least one 23G variant allele (AG/GG genotypes) had a significantly increased risk for ALL (adjusted OR 2.02; 95%CI 1.08 - 3.78) compared with the wild-type genotype (23AA), and evidence that positive interactions between the polymorphisms in XPC C499T and XPA A23G might occur. Furthermore, individuals with both putative risk genotypes had a significantly higher risk (adjusted OR 5.60; 95%CI 1.57 - 19.90), compared with those with both wild-genotypes. By contrast, no significant association was observed between the XPD T751G, XRCC1 G399A, C194T polymorphism and ALL risk. CONCLUSIONS: XPA A23G and XPC C499T polymorphism may contribute to the risk of developing ALL. There are significant combinations between XPC C499T and XPA A23G.
