Project description:Pouchitis is a common complication for ulcerative colitis (UC) patients with ileal pouch-anal anastomosis (IPAA) surgery. Similarly to IBD, both innate host factors such as genetics, and environmental stimuli including the tissue-associated microbiome have been implicated in the pathogenesis. In this study, we make use of the IPAA model of inflammatory bowel disease (IBD) to carry out a study associating mucosal host gene expression with the microbiome and corresponding clinical outcomes.
Project description:2000 ulcerative colitis cases drawn from the UKIBD Genetics
Consortium cohort and whole-genome sequenced at 2X depth. A case
control association study using control samples whole-genome sequenced
by UK10K will be undertaken to identify common, low-frequency and rare
variants associated with ulcerative colitis. Data will be combined
with similar data across 3000 Crohn's disease cases from the same
cohort to identify inflammatory bowel disease (IBD) loci and better
understand the genetic differences and similarities of the two common
forms of IBD.
