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