干扰素调节因子5基因rs2004640多态性与系统性红斑狼疮遗传易感性的荟萃分析

目的:系统评价干扰素调节因子5基因(IRF5)rs2004640单核苷酸多态性与系统性红斑狼疮的遗传易感性在不同种族的相关关系。方法:检索Pubmed数据库、万方数据库、CNKI数据库发表的有关IRF5 rs2004640单核苷酸多态性与SLE病例对照研究的文献,应用review manager5软件,采用Mantel-Haenszel-Peto法荟萃分析IRF5 rs2004640单核苷酸多态性在不同种族中的研究。结果:荟萃分析包括亚洲、欧洲-美洲高加索人群、墨西哥印欧混血、美国黑人等不同人群的IRF5 rs2004640单核苷酸多态性14个研究,共11 725例样本。亚洲人群IRF5 rs2004640 T等位基因频率26.3%~45.5%,高加索人群IRF5rs2004640 T等位基因频率44%~56%。分别荟萃分析亚洲和高加索人群与该多态性位点关联,均提示这两种人群IRF5rs2004640 T等位基因与狼疮发病密切相关(亚洲人群OR值1.35,95%CI 1.22~1.50;高加索人群OR值1.42,95%CI 1.32~1.54;P<10-6)。荟萃分析总的结果表明IRF5 rs2004640 T等位基因与狼疮发病密切相关(OR=1.42,P<10-6)。结论:IRF5rs2004640基因多态性在不同种族人群中的荟萃分析肯定了IRF5 rs2004640 T等位基因和系统性红斑狼疮发病相关。

Association between the rs2004640 polymorphism of interferon regulatory factor 5 and systemic lupus erythematosus:a meta-analysis

Objective:The aim of this study is to determine whether the functional interferon regulatory factor 5(IRF5) polymorphism,rs2004640,confers susceptibility to systemic lupus erythematosus(SLE) in multiple ethic populations.Methods:A meta-analysis was conducted on the T allele of the IRF5 rs2004640 polymorphism,and 14 studies with different ethinic populations retrieved from Pubmed database,Wanfang database and CNKI database were included in the meta-analysis.The meta-analysis was performed according to the Ma...
