HLA-C and irritable bowel syndrome: Similarly, we found 24 GWS (Pgene-diverticular-disease < 2.62 × 10−6) genes for diverticular disease, two for IBS (Pgene-IBS < 2.62 × 10−6, HLA-C and PITPNM2), and 26 for IBD (Pgene-IBD < 2.62 × 10−6) that were associated with T2D (Pgene-T2D < 0.05) [Supplementary Data 25–27].
