Method: Using data from the Genome-Wide Association Study (GWAS), mendelian randomization analysis was performed with EPAS1 as an exposure factor and T2DM as an outcome variable. In this paper, Inverse Variance Weighting (IVW) was used as the primary analysis method to pool and combine the causal effect estimates of Single Nucleotide Polymorphisms (SNPs), and MR-Egger regression, weighted median, and weighted model were used as supplementary methods to analyze the potential causal association between the two. Cochran’s Q test, MR-Egger regression intercept, and leave-one-out method were used for sensitivity analysis. Results: IVW analysis showed that EPAS1 and T2DM had a significant positive causal relationship (OR: 1.055, 95% CI: 1.044~1.067, P = 6.96e–22). Sensitivity analysis showed no pleiotropy but significant heterogeneity, and the results were relatively reliable. Conclusion: EPAS1 and T2DM have a significant positive causal relationship, but further verification is needed.展开更多
