摘要
目的从基因水平探讨HLA-DRB1、DQB1等位基因多态性与流行性出血热的相关性,以阐述其免疫遗传学特征。方法应用序列特异性引物聚合酶链反应技术检测流行性出血热患者和正常对照组各50例的HLA-DRB1、DQB1等位基因。结果流行性出血热患者与正常对照组比较,HLA-DRB1*16等位基因分布频率明显增高(Pc=0.010 6),两组间其余HLA-DRB1-、DQB1等位基因分布频率差异无统计学意义(Pc>0.05)。结论HLA-DRB1*16等位基因与流行性出血热呈正相关,可能为流行性出血热易感基因之一。
Objective To explore the hereditary susceptibility of HLA-DRB1 and -DQB1 alleles of epidemic hemorrhagic fever （EHF） at gene level and to further the features of their immunogenetics. Methods The polymorphisms of HLA-DRBI and -DQB1 alleles were typed by sequence specific primer based on polymerase chain reaction in 50 patients with EHF and 50 normal control subjects. Results The allele frequency of HLA-DRBI ＊ 16 allele was significantly higher in patients than that in normal controls （Pc =0.010 6）. There was no significantly difference between the rested alleles of HLA-DRB1 and -DQBI in two groups （Pc 〉0.05）. Conclusions HLA-DRB1 ＊ 16 allele was initially be determined predisposing gene of EHF.
