Multiple resources were used to identify previously reported associations of our 30 significant SNPs with other phenotypes. We used the IEU open gwas project92, PheWAS analysis of gwasATLAS52, the NHGRI-EBI GWAS Catalog91, and identified credible SNPs through causaldb90. Causaldb estimates causal probabilities of all genetic variants in GWAS significant loci using three state-of-the-art fine-mapping tools including PAINTOR, CAVIARBF and FINEMAP108–111. We used default settings for our causaldb queries.
