               [摘   要] 目的:研究肝细胞核因子(hepatocyte nuclear factor 1,HNF)1A和HNF1B基因遗传变异与乳腺癌遗传易感性之间的
                相关性。方法:采用病例对照研究,选取1 032例经病理组织学确诊的乳腺癌患者以及与之相匹配的1 063例健康女性对照,应
                用Illumina基因分型平台对HNF1A和HNF1B基因多态位点进行基因分型检测;在调整年龄、初潮年龄、绝经状态的基础上,通
                过Logistic回归计算OR值及95%CI,比较不同基因型与乳腺癌发病风险之间的相关性。结果:位于HNF1A基因上的3个位点
                                                                                                                -
                与中国人群乳腺癌发病风险显著相关,其中包括 HNF1A 基因外显子区的 rs2464196(OR=0.80,95%CI:0.71~0.91,P=7.45×10
                4
                ),HNF1A 基因内含子区的 rs1183910(OR=0.87,95% CI:0.77~0.99,P=0.039)和 rs7310409(OR=0.86,95% CI:0.76~0.98,P=
                0.023)。进一步 FDR 校正后,rs2464196 位点与乳腺癌易感性仍然存在着显著的相关性(P=4.47×10 )。结论:肝细胞核因子
                                                                                             -3
                HNF1A基因上的rs2464196多态位点可能是中国人群乳腺癌的易感标志物。

               [Abstract] Objective:We investigated whether genetic variants of HNF1A and HNF1B were associated with the risk of breast
                cancer in a Chinese Han population. Methods:A case⁃control study of 1 032 breast cancer cases and 1 063 cancer⁃free female controls
                was performed,and six single nucleotide polymorphisms(SNPs)in HNF1A and HNF1B were genotyped in Illumina genotyping
                platform. Logistic regression was used to calculate the odds ratios(ORs)and 95% confidence intervals(CIs)for the association between
                a single locus and breast cancer risk with adjustment for age,age at menarche,and menopausal status. Results:Multiple logistic
                regression analysis illustrated that three SNPs within HNF1A gene were associated with significantly decreased risk of breast cancer
               (rs2464196,OR=0.80,95%CI:0.71~0.91,P=7.45×10 ;rs1183910,OR=0.87,95%CI:0.77~0.99,P=0.039;rs7310409,OR=0.86,
                                                        - 4
                95% CI:0.76~0.98,P=0.023). After correction for multiple comparisons(FDR<0.05),rs2464196 was still significantly associated
                                                  -3
                with susceptibility to breast cancer(P=4.47×10 ). Conclusion:The SNP rs2464196 within HNF1A gene may be a candidate marker
                for susceptibility to breast cancer in Chinese Han population.
