Background: Predisposition to hyperthyroidism may be influenced by functional gene polymorphisms in tumor necrosis factor-α (TNF-α), interleukin-1 (IL-1), interleukin-4 (IL-4), interleukin-6 (IL-6), and interleukin-10 (IL-10). However, the results of the studies published so far remain discrepant, so we conducted a meta-analysis to more robustly investigate relationships between TNF-α/IL-1/IL-4/IL-6/IL-10 polymorphisms and predisposition to hyperthyroidism. Methods: A comprehensive literature retrieval from PubMed, Embase, Web of Science, WanFang, VIP, and CNKI was endorsed by the authors, and 38 studies were found to be eligible for pooled meta-analyses. Results: We found that genotypic frequencies of TNF-α −308 G/A, IL-1A −889 C/T, IL-6 −174 G/C, IL-6 −572 G/C, IL-10 −819 C/T, and IL-10 −1082 A/G polymorphisms among cases were significantly different from those among controls. Moreover, we also found that genotypic frequencies of TNF-α −308 G/A and IL-6 −174 G/C polymorphisms among cases of Caucasian origin were significantly different from those among Caucasian controls, and genotypic frequencies of IL-1A −889 C/T, IL-1B −511 C/T, IL-6 −174 G/C, IL-6 −572 G/C, and IL-10 −1,082 A/G polymorphisms among cases of Asian origin were also significantly different from those among Asian controls. Conclusions: This meta-analysis suggests that TNF-α −308 G/A, IL-1A −889 C/T, IL-1B −511 C/T, IL-6 −174 G/C, IL-6 −572 G/C, IL-10 −819 C/T, and IL-10 −1,082 A/G polymorphisms may influence predisposition to hyperthyroidism in certain ethnic groups.
