ABSTRACT
Objective To investigate the associations between the polymorphisms in CD40‐1C/T polymorphism(rs1883832) and Graves′disease by Meta‐analysis .Methods We searched Pubmed ,CBM ,VIP ,CNKI ,Cochrane library and Wanfang ,covering and selecting literatures according to criterions .Statistical analysis was performed by using Revman5 .2 and Stata12 .0 .Results A total of 18 eligible literatures were included(5 198 cases and 4 417 controls) ,The pooling results suggested that significant differ‐ence in allele C/T frequency and genotype frequency were observed between patients with and control subjects (P0 .05) .Conclusion This Meta analysis indicated that the polymorphisms in the CD40 gene(rs1883832) was related with Graves′disease ,but had nothing to do with family history and Graves′disease with ophthalmopathy .
