IKZF4 and vitiligo: Other polymorphisms found in the GWAS and associated with other autoimmune diseases include ZNF365 (atopic eczema, ankylosing spondylitis, Crohn’s disease, psoriasis, primary sclerosing cholangitis, ulcerative colitis, posterior probability = 1.0), TNFSF4 (eczema, asthma and allergic diseases, posterior probability = 1.0), NAB1 (primary biliary cholangitis r2 = 0.48, rheumatoid arthritis, r2 = 0.15) and IKZF4-ERBB (vitiligo and alopecia areata r2 = 0.36) (see Table Supplementary Data 1 and Supplementary Fig. 2 for functional descriptions and associations).
