Thyroid stimulating hormone receptor(TSHR) is thought to be a significant candidate for genetic susceptibility to Graves’ disease(GD).However,the association between TSHR gene polymorphism and the risk of GD remains controversial.In this study,we investigated the relationship between the two conditions by meta-analysis.We searched all relevant case-control studies in PubMed,Web of Science,CNKI and Wanfang for literature available until May2015,and chose studies on two single nucleotide polymorphisms(SNPs):rs 179247 and rsl2101255,within TSHR intron-1.Bias of heterogeneity test among studies was determined by the fixed or random effect pooled measure,and publication bias was examined by modified Begg’s and Egger’s test.Eight eligible studies with 15 outcomes were involved in this meta-analysis,including 6,976 GD cases and 7,089 controls from China,Japan,Poland,UK and Brazil.Pooled odds ratios(ORs) for allelic comparisons showed that both TSHR rsl79247A/G and rsl2101255T/C polymorphism had significant association with GD(OR=1.422,95%CI=1.353—1.495,P<0.001,P_(heterogeneity)=0.448;OR= 1.502,95%CI:1.410-1.600,P<0.001,P_(heterogeneity)=0.642),and the associations were the same under dominant,recessive and co-dominant models.In subgroup analyses,the conclusions are also consistent with all those in Asian,European and South America subgroups(P<0.001).Our meta-analysis revealed a significant association between TSHR rsl79247A/G and rsl2101255T/C polymorphism with GD in five different populations from Asia,Europe and South America.Further studies are needed in other ethnic backgrounds to independently confirm our findings.
