摘要
Objective. Accumulating Studies indicate that HPV E6/E7 oncoproteins interacting genes, TP53, BRCA1 and BARD1, play a critical role in cervical carcinogenesis. We hypothesized that potentially functional polymorphisms in TP53, BRCA1 and BRAD1 may individually and/or jointly contribute to cervical cancer risk. Methods. We genotyped 4 single nucleotide polymorphisms (SNPs) with amino acid changes, TP53 Pro72Arg (rs1042522), BRCA1 Pro871Leu (rs799917), BARD1 Pro24Ser (rs1048108) and Arg378Ser (rs2229571), in a case-control study of 404 cervical cancer cases and 404 cancer-free controls in Chinese women. Results. Logistic regression analysis showed that the BRCA1 variant rs799917 TT genotype was associated with a significantly decreased risk of cervical cancer in a recessive genetic model (adjusted OR = 0.62, 95% CI=0.40-0.95), compared with the genotypes CT/CC. However, no significant associations with cervical cancer were observed for other 3 SNPs (adjusted OR = 1.01, 95% CI = 0.68-1.50 for rs1048108 TT vs CT/CC; adjusted OR = 1.04, 95% CI = 0.67-1.64 for rs2229571 CC vs GG/GC: adjusted OR = 0.84, 95% CI = 0.59-1.20 for rs1042522 CC vs GG/GC). Conclusion. These findings indicate that BRCA1 rs799917 polymorphism may contribute to the risk of cervical cancer in this Chinese population, and further validation in other Populations are warranted.
