Cytotoxic T lymphocyte-associated antigen-4 (CTLA-4) plays an important role in the initiation and development of Graves' disease (GD), especially CTLA-4 +49A/G polymorphism and genetic susceptibility to GD. However, the current conclusions are consistent. Therefore, this study adopted meta-analysis method to assess the exact correlation between this polymorphism and GD risk.
Methods: Literature searches were performed in PubMed, Embase, Web of Science, China National Knowledge Infrastructure, China Wanfang, and other databases for data on the correlation between polymorphisms of CTLA-4 +49A/G and GD risk. The end date for publications was May 2020. Stata 15.0 software was used for data analysis.
Results: A total of 33 papers were included, covering 8,555 cases and 9,533 controls. The results showed that the CTLA-4 +49 allele G compared to allele A, odds ratio (OR) = 1.62, 95% CI [1.56, 2.09]. In the dominant, recessive, homozygous, and heterozygous genetic models, comparing the GD group and the control group, the combined OR was 1.81, 95% CI [1.56, 2.09]; 1.91, 95% CI [1.66, 2.21]; 2.75, 95% CI, [2.21, 3.41]; and 1.49, 95% CI [1.29, 1.71], respectively. When it was analyzed by dividing genetic models into subgroups according to ethnicity and published year, the data the of genetic model in each subgroup were also statistically significant.
Conclusion: The CTLA-4 +49A/G polymorphism was strongly associated with genetic susceptibility to GD. Allele G, genotypes GG, GG + GA, and GA are correlated with an increase in the risk of GD.
