Crohn's disease the risk of developing Crohn disease are ATG16L1, IL23R, IRGM, and SLC11A1. There is considerable overlap between susceptibility loci for IBD and mycobacterial infections. Recent genome-wide association studies have shown that Crohn's disease is genetically linked to coeliac disease. Crohn's has been linked to the gene LRRK2 with one variant potentially increasing the risk of developing the disease by 70%, while another lowers it by 25%. The gene is responsible for making a protein, which collects and eliminates waste product in cells, and is also associated with Parkinson's disease. There was a prevailing view that Crohn's disease is a primary
