Mutation spectrum of NOD2 in inflammatory bowel disease (IBD) patients. NOD2 variation identified in patients with pediatric early onset IBD (upper) and adult IBD cohort from the RGC-GHS DiscovEHR collaboration (lower). Variants in blue were observed in both cohorts; variants in red are predicted loss-of-function that result in nonsense mediated decay. The three “common” low-frequency Crohn’s Disease risk variants are highlighted: R702W (purple), G908R (brown), and L1007fs (green). Also depicted are the NOD2 protein structural domains: two caspase activation and recruitment domains (CARD), a nucleotide binding and oligomerization (NOD) domain, and leucine rich repeat domains in yellow.
