类风湿关节炎易感基因的全基因组关联分析研究进展

类风湿关节炎(rheumatoid arthritis,RA)是一种炎性侵润关节及其周围结缔组织的系统性自身免疫疾病,也是一种具有复杂遗传模式的多基因遗传病。环境因素和遗传因素共同影响RA的发生、发展。它的易感基因研究给临床的诊断、治疗提供了理论基础。新兴的全基因组关联分析作为寻找易感基因的高通量技术,是发现多基因遗传性疾病包括RA易感基因的强大工具。它不仅能够验证已有的易感基因位点,还能够发现新的候选易感位点。近5年来,用全基因组关联分析研究易感基因取得了很多新的进展,为探明RA的发病机制和治疗RA提供了新的契机。本文就近年来全基因组关联分析技术研究RA易感基因的进展做一综述。

Identifying susceptible genes of rheumatoid arthritis by genome-wide association study:an advance

Rheumatoid arthritis(RA),a systemic,inflammatory autoimmune disorder characterized by inflammation of the lining or synovium of the joints,is a complex polygenic disease with a complicated inheritance mode.Both genetic and environmental factors determine the development and progression of RA.Study on susceptible genes of RA provides a theoretic basis for clinical diagnosis and treatment.As a novel high-throughput screening method,genome-wide association study(GWAS) is a powerful approach for mapping suscept...
