Inflammatory bowel disease (IBD) is a common and chronic gut disorder, with two subtypes: Crohn's disease (CD) and ulcerative colitis (UC), which are challenging to diagnose. The molecular pathology IBD is not well understood, and the underlying gene regulatory regions have not been comprehensively investigated. Relatedly, most IBD-associated SNPs are located in non-coding regions, and may effect gene regulation. Here, we profiled genome-wide promoter and enhancer activity in the descending colon of IBD patients. IBD-induced enhancer and promoters are highly enriched for IBD-associated SNPs, and can predict IBD diagnosis with an accuracy of 85% in an external cohort.
