摘要: 目的 通过调查江苏地区汉族人群人类白细胞抗原-E( HLA-E) 等位基因多态性分布情况,为探讨HLA -E 基因多态性与疾病关联奠定基础。方法 采用聚合酶链反应–序列特异性引物( PCR-SSP) 方法,调查217例江苏地区汉族献血人群HLA-E的表达。结果 检测到HLA-E 的2个等位基因,分别是HLA-E*01:01和HLA-E*01:03,分布频率为41.47%和58.53%;基因型HLA-E*01:01/01:01、01:01/01:03和01:03/01:03的频率分别为14.74%、53.46%和31.80%,分布符合Hardy-weinberg 平衡定律。结论 江苏地区汉族人群HLA-E高度保守,仅有2种基因型。

Abstract: Objective To investigate the genetic polymorphisms of HLA-E locus in Han population of Jiangsu region.Methods The genomic DNA extracted from 217 unrelated healthy blood donors were amplified by using HLA-E specific PCR primers.Results Two alleles including HLA-E* 01:01 and HLA-E* 01:03 were identified,the frequencies were 41.47% and 58.53%,respectively.The frequencies of the three HLA-E genotypes(HLA-E*01:01/01:01,01:01/01:03 and 01:03/01:03)were 14.74%,53.46% and 31.80%,respectively,and they were in accordance with Hardy-Weinberg Equilibrium.Conclusion The polymorphism of HLA-E in the Han population of Jiangsu province was highly conserved,suggesting a role of HLA-E in disease association and clinical transplantation.
