摘 要:目的分析重庆地区汉族人群HLA-A、B、DRB1在高分辨基因分型水平上多态性及分布特征。方法采用聚合酶链反应-序列特异性寡核苷酸探针(PCR-SSOP)基因分型以及基因序列分型(SBT)技术,对重庆地区2 067例无关供者的HLA-A、B、DRB1位点上的等位基因进行高分辨分型,直接计数法计算等位基因频率,应用Arlerquin3.1软件进行Hardy-Weinberg平衡检验。结果共检出了168种HLA高分辨等位基因。其中HLA-A位点42种,频率大于0.05有A*11:01,A*24:02,A*02:07,A*02:01,A*33:03;HLA-B位点81种,频率大于0.05有B*46:01,B*40:01,B*58:01,B*13:01,B*15:02;HLA-DR位点45种,频率大于0.05有DRB1*09:01,DRB1*15:01,DRB1*12:02,DRB1*08:03,DRB1*11:01。结论获得了重庆地区汉族人群HLA-A、B、DRB1高分辨等位基因频率数据,为人类学、法医学、移植配型及疾病相关性等研究提供可靠的参考数据。Objective To analyze the HLA-A ,B and DRB1 alleles high-resolution polymorphism in Chongqing Han population . Methods The PCR-SSOP and PCR-SBT methods were applied for the HLA high-resolution genotyping of 2 067 unrelated healthy donors in the registry of Chongqing branch of Chinese National Marrow Donor Program (CMDP) .The allele frequencies of HLA-A , B and DRB1 were estimated by the direct counting method and the Hardy-Weinberg equilibrium inspection was performed by using the Arlequin software 3 .1 .Results 168 high-resolution alleles were detected out ,in which 42 alleles of A*11 :01 ,A*24:02 ,A*02:07 ,A*02 :01 and A*33:03 at the HLA-A locus were observed with the frequencies greater than 0 .05 ;81 alleles were detected at HLA-B locus ,including B*46 :01 ,B*40:01 ,B*58 :01 ,B*13 :01 and B*15 :02 with the frequencies greater than 0 .05 ;45 al-leles of DRB1*09:01 ,DRB1*15 :01 ,DRB1*12 :02 ,DRB1*08 :03 and DRB1*11 :01 at the HLA-DR locus were observed with the frequencies greater than 0 .05 .Conclusion The data of the HLA-A ,B and DRB1allelic frequencies at high-resolution level in Chongqing Han population are obtained ,which provides the reliable reference data for the studies of anthropology ,forensic medi-cine ,transplantation matching and disease association .
