We previously tested whether genes coregulated by the “Th17 core” (RORC, STAT3, BATF, IRF4, and MAF) were enriched for gene sets from GWAS of nine autoimmune diseases and three “negative controls” (Alzheimer's, schizophrenia, and type 2 diabetes) (Ciofani et al. 2012). The gene discussed is RORC; the disease is autoimmune disease.
