摘要
自身免疫性甲状腺疾病(autoimmune thyroid disease,AITD)是一种主要由T细胞介导的器官特异性自身免疫性疾病,包括格雷夫斯病(Graves disease,GD)和桥本甲状腺炎(Hashimoto thyroiditis,HT),其发病率与遗传因素紧密相关。本研究旨在确定与AITD相关的易感基因及位点。本研究通过对100例AITD(51例HT和49例GD)患者和50例健康体检者的基因组进行目标区域测序,并对基因多态性与AITD之间的相关性进行了统计学分析,进一步进行连锁分析找到易感基因及相关位点。本研究发现了BACH2基因的5个单核苷酸多态性(single nucleotide polymorphism,SNP)位点(rs12205059、rs62408219、rs7742121、rs7756574、rs12204886)完全连锁,ARID5B基因10个SNP位点(rs12778514、rs3740354、rs3740353、rs9633555、rs9633557、rs9633534、rs3740352、rs2393730、rs2393729、rs2393728)连锁程度较高,NFKB1基因7个SNP位点(rs230528、rs230526、rs230521、rs230517、rs230512、rs4648011、rs230505)连锁程度较高,它们显示与GD显著相关;BACH2基因24个SNP位点(rs77175037、rs16882370、rs77758469、rs78777913、rs117721419、rs78336372、rs76671310、rs76587383、rs75249386、rs79815784、rs57765055、rs75199762、rs75340880、rs9444735、rs61246723、rs9451336、rs78318422、rs117023048、rs74639869、rs75487886、rs80029445、rs78252829、rs60148132、rs58745003)完全连锁,以及4个SNP位点(rs60519986、rs56835438、rs58205153、rs9451298)连锁程度较高,显示与HT显著相关;BACH2基因4个SNP位点(rs12205059、rs7742121、rs7756574、rs12204886)连锁程度较高,ARID5B基因5个SNP位点(rs9633555、rs9633556、rs2393730、rs2393729、rs2393728)连锁程度较高,它们与GD和HT易感性均显著相关。本研究揭示了BACH2、ARID5B和NFKB1基因的多态性与AITD易感性有关,它们可能参与了AITD的发病机制。
Autoimmune thyroid disease(AITD)is an organ-specific autoimmune disease mainly mediated by T cells,including Graves disease(GD)and Hashimoto thyroiditis(HT).The incidence of AITD is closely related to genetic factors.The aim of this study is identifying susceptibility genes and loci associated with AITD.In this study,the genomes of 100 patients with AITD(51 HT and 49 GD)and 50 healthy subjects were sequenced in targeted regions,and the correlation between gene polymorphisms and AITD was statistically analyzed,and further linkage analysis was performed to find susceptibility genes and associated loci in genes.In this study,five SNP loci(rs12205059,rs62408219,rs7742121,rs7756574,rs12204886)in BACH2 gene were found to be completely linked,ten SNP loci(rs12778514,rs3740354,rs3740353,rs9633555,rs9633557,rs9633534,rs3740352,rs2393730,rs2393729,rs2393728)in ARID5B gene were highly linked,seven SNP loci(rs230528,rs230526,rs230521,rs230517,rs230512,rs4648011,rs230505)in NFKB1 gene were highly linked,and they showed significant correlation with GD;twenty-four SNP loci(rs77175037,rs16882370,rs77758469,rs78777913,rs117721419,rs78336372,rs76671310,rs76587383,rs75249386,rs79815784,rs57765055,rs75199762,rs75340880,rs9444735,rs61246723,rs9451336,rs78318422,rs117023048,rs74639869,rs75487886,rs80029445,rs78252829,rs60148132,rs58745003)in BACH2 gene were completely linked,and four SNP loci(rs60519986,rs56835438,rs58205153,rs9451298)were highly linked,showing significant correlation with HT;four SNP loci(rs12205059,rs7742121,rs7756574,rs12204886)in BACH2 gene were highly linked,and five SNP loci(rs9633555,rs9633556,rs2393730,rs2393729,rs2393728)in ARID5B gene were highly linked,and they all showed significant association with GD and HT susceptibility.This study reveals that the polymorphisms of BACH2,ARID5B and NFKB1 genes are associated with AITD susceptibility,and they may be involved in the pathogenesis of AITD.
