Shared and individual inflammatory bowel disease (IBD) and Asthma susceptibility genes/loci. The outlined genes are grouped according to function. In green color are the genes associated to asthma, in blue color are the genes associated to ulcerative colitis only, in orange color are the genes associated to Crohn’s disease only, in purple color are the genes associated to IBD, in black color are the genes associated to asthma and Crohn’s disease or asthma and IBD, respectively.
