沈阳汉族群体HLAⅠ类基因座PCR-序列特异性寡核苷酸探针分型研究

目的检测和分析沈阳汉族HLA-A、-B、-Cw位点等位基因的多态性。方法采用聚合酶链反应．寡核苷酸探针杂交分型方法对108名沈阳籍健康献血员进行HLA-A、-B、-Cw等位基因分型。结果检出等位基因HLA-A位点21个，B位点43个，Cw位点23个；所有位点的等位基因频率分布符合Hardy—Weinberg平衡。结论从基因水平分析了HLA Ⅰ类基因的群体分布特征，提供了沈阳汉族群体HLA Ⅰ类基因座更准确的基因频率。

High resolution DNA typing for HLA-A, B, Cw genes by polymerase chain reaction-sequence specific oligonucleotide probes method in the Shenyang Han population

OBJECTIVE: To investigate, at the DNA level, the polymorphism of HLA-A, -B, -Cw genes in the Chinese of Han ethnicity in Shenyang. METHODS: Hybridization with polymerase chain reaction-sequence specific oligonucleotide probes (PCR-SSOP) was used to determine HLA-A, -B and -Cw genotypes of 108 unrelated healthy individuals from a Chinese Han population. These Hans were born and living in the Shenyang area. RESULTS: The numbers of alleles identified were 21 for HLA-A, 43 for HLA-B, and 23 for HLA-Cw. All the allele frequency distributions were consistent with the Hardy-Weinberg equilibrium. CONCLUSION: Using molecular method, the present authors have analyzed the characteristic of HLA I distribution in a group of indigenous Hans in Shenyang and thus have provided more accurate gene data for use in related researches.
