  • Genetic architecture of the inflammatory bowel diseases across East Asian and European ancestries - Unknown journal (n.d.) · Unknown authors · PubMed 37156999

    ABSTRACT: Inflammatory bowel diseases (IBD) are chronic disorders of the gastrointestinal tract with two subtypes: Crohn's disease (CD) and ulcerative colitis (UC). To date, most IBD genetic associations were derived from individuals of European ancestries (EUR). Here we report the largest IBD study of individuals of East Asian ancestries (EAS), including 14,393 cases and 15,456 controls. We found 80 IBD loci in EAS alone and 320 when meta-analyzed with ~370,000 EUR individuals (~30,000 cases), among which 81 are novel. EAS enriched coding variants implicate many new IBD genes, including ADAP1 and GIT2. While IBD genetic effects are generally consistent across ancestries, genetics underlying CD appears more ancestry dependent than UC, driven by both allele frequency (NOD2) and effect (TN

  • Association analyses identify 38 susceptibility loci for inflammatory bowel disease and highlight shared genetic risk across populations - Unknown journal (n.d.) · Unknown authors · PubMed 26192919

    ABSTRACT: Ulcerative colitis and Crohn's disease are the two main forms of inflammatory bowel disease (IBD). Here, we report the first trans-ethnic association study of IBD, with genome-wide or Immunochip genotype data from an extended cohort of 86,640 European individuals and Immunochip data from 9,846 individuals of East-Asian, Indian or Iranian descent. We implicate 38 loci in IBD risk for the first time. For the majority of IBD risk loci, the direction and magnitude of effect is consistent in European and non-European cohorts. Nevertheless, we observe genetic heterogeneity between divergent populations at several established risk loci driven by a combination of differences in allele frequencies (NOD2), effect sizes (TNFSF15, ATG16L1) or a combination of both (IL23R, IRGM).
