RESUMO

Various studies have investigated the risk of preeclampsia with the forkhead box protein P3 (FOXP3) gene rs2232365 and rs3761548 polymorphisms. However, the results remained contradictory. A comprehensive literature search was conducted using the Cochrane Library, PubMed, and Web of Science (up to Oct 11, 2021). Meta-analysis was carried out in the R language environment for statistical computing and graphics. A fixed-effect or random-effects model was used according to the statistical significance of heterogeneity among included studies. The pooled odds ratios and corresponding 95% confidence intervals were calculated to estimate the strength of the effect. For the rs2232365 polymorphism, statistical significance was detected neither in the overall population nor among the East Asian and West Asian subgroups. However, for rs3761548, the summarized statistics revealed a significant association between the C allele carriage and preeclampsia risk in the homozygote, heterozygote, and dominant models. The further stratified analysis found this effect might be specific to West-South Asian ethnic subgroups. To sum up, this meta-analysis showed that the FOXP3 rs3761548 polymorphism was significantly associated with preeclampsia susceptibility, and it had a deleterious effect especially in the West-South Asian population. In contrast, rs2232365 may serve as neither a protective nor a risk factor for preeclampsia onset.

RESUMO

BACKGROUND: Many published studies attempted to elucidate the implication of glucokinase regulator gene (GCKR) polymorphisms in the susceptibility to non-alcoholic fatty liver disease (NAFLD), but the results among them were still controversial. OBJECTIVE: This meta-analysis aims to precisely assess the relationship between the GCKR polymorphisms and the risk of NAFLD. METHODS: Systematic computerized searches in six databases were performed and updated on April 6, 2020. Meta-analyses were conducted by calling the R programs based on accumulated epidemiological data. Odds ratio (OR) and 95% confidential interval (CI) were calculated to summarize the effect estimates. RESULTS: In total, 25 studies including 6,598 cases and 19,954 controls were included. The pooled estimates indicated that the T allele carrier of the GCKR rs780094 polymorphism has predisposition to NAFLD (allele model: OR: 1.20, 95% CI: 1.11~1.29; homozygote model: OR: 1.38, 95% CI: 1.15~1.67; heterozygote model: OR: 1.25, 95% CI: 1.12~1.39; dominant model: OR: 1.29, 95% CI: 1.13~1.47; recessive model: OR: 1.18, 95% CI: 1.06~1.31), and the same as the rs1260326 polymorphism (allele model: OR: 1.32, 95% CI: 1.22~1.42; homozygote model: OR: 1.65, 95% CI: 1.40~1.94; heterozygote model: OR: 1.24, 95% CI: 1.07~1.43; dominant model: OR: 1.39, 95% CI: 1.21~1.59; recessive model: OR: 1.44, 95% CI: 1.28~1.62). Further stratified analyses according to age and ethnicity confirmed the statistical existence in most subgroups. CONCLUSION: This meta-analysis suggested that both of the GCKR rs780094 and rs1260326 polymorphisms are significantly associated with the increased risk of NAFLD.
