Circular diagrams showing the genes shared between nine autoimmune diseases. The nine diseases are shown on the outer circle in colored bands, with their abbreviated names. The ribbons depicting the shared genes are colored according to the number of disease phenotypes they are shared by (grey, two AIDs; blue, three AIDs; red, four AIDs; black, five AIDs). (A) lncRNA genes and (B) protein-coding genes shown in this figure include genes specific to Crohn's disease (CD), celiac disease (CeD), inflammatory bowel disease, shared by Crohn's disease and ulcerative colitis (IBD shared), juvenile idiopathic arthritis (JIA), primary biliary cirrhosis (PBC), psoriasis (PS), primary sclerosing cholangitis (PsCh), rheumatoid arthritis (RA), and ulcerative colitis specific (UC) genes. These two plots are presented at higher resolution in Additional files 8 and 9).
