IBD Genomics


We are zooming in the 200 plus GWAS peaks that have been identified over the last ten years for Crohn’s disease and/or ulcerative colitis. Our aim is to identify the corresponding causative variants and genes as a way to pinpoint putative drug targets and develop better diagnostic tools.  To that end, we continue to generate various “omic” data in disease relevant cell-types for hundreds of healthy and diseased individuals including for eQTL and microbiome analyses.
