【摘要】 目的研究广西地区汉族人群HLA-B15和HLA-B40组抗原的等位基因和特异性的分布情况,探讨其可能对临床供者选择的影响。方法采用多聚酶链式反应-基于测序的分型技术(PCR-SBT)对广西地区1 644名汉族人进行HLA-B基因分型,采用直接计算法计算每个等位基因的频率,分析各等位基因的抗原特异性,将HLA-B15和HLA-B40组的基因频率和与其他人群比较。结果 1 644名广西地区汉族人HLA-B位点基因频率不符合Hardy-Weinberg遗传平衡(P<0.05)。HLA-B15组共检出14个等位基因,分属5种抗原特异性;HLA-B40组共检出6个等位基因,分属2种抗原特异性。结论广西地区汉族人群HLA-B15和HLA-B40组抗原多态性比较接近中国南方汉族人群,但也有广西地区特点。更多还原

【Abstract】 Objective To investigate the allele and specificity distribution situation of HLA-B15 group and HLA-B40 group antigens among Han population in Guangxi area and to explore their possible influence on transplantation donors selection in clinic.Methods The blood samples of 1 644 Han donors in Guangxi region were performed the HLA-B genotyping by PCR-SBT,the frequencies of each allele were calculated by the direct computing method.The antigen specificity of various alleles were analyzed,then the gene frequencies of HLA-B15 and HLA-B40 groups were compared with those from other populations.Results The gene frequency at HLA-B locus in 1 644 Han persons was inconsistent with the Hardy-Weinberg equilibrium(P<0.05).Fourteen alleles in HLA-B15 group were detected out,which belonged to 5kinds of antigen specificity.In the HLA-B40 group,6alleles were detected out,which belonged to two kinds of antigen specificity.Conclusion The antigen polymorphism of HLA-B15 and HLA-B40 groups among Han population in Guangxi area is close to that in southern Chinese Han populations,but which still keeps its characteristics of Guangxi area.更多还原
