Several GWAS loci were found in this region for T1D (rs3842753, rs689), T2D (rs3842770, rs571342427), severe autoimmune type 2 diabetes (rs3842753), glucose levels (rs3842753, rs3842752), and IGF1 levels (rs3842752) based on the GWAS catalog (Figure 1C, red text) [8,50,51,52,53,54,55,56,57,58,59,60]. Here, IGF1 is linked to type 2 diabetes mellitus.
