However, we found weak evidence for colocalization between eQTL and GWAS signals for CTRB1/2 loci (rs7202877; posterior probability = 35.2%) in both diseases, and SH2B3 loci (rs3184504; posterior probability = 34.7%) in T1D (Supplementary Table S8). This evidence concerns the gene CTRB1 and type 1 diabetes mellitus.
