We found that the well-known GLIS3 GWAS locus associated with FG and T1D-risk67,68 colocalized with a fetal-like iPSC-PPC-unique singleton egQTL for the lncRNA CDC37L1 divergent transcript (CDC37L1-DT; effect size = 1.46; PP.H4 for FG and T1D = 92.4% and 91.2%, respectively, Fig. 6b, Supplementary Fig. 14B, Supplementary Data 13). This evidence concerns the gene GLIS3 and type 1 diabetes mellitus.
