  • Genomic Insights Into Inflammatory Bowel Disease in United States Hispanic Participants: An Ancestry-Focused Study. - Gastroenterology (2026) · Beecham AH, McGovern DPB, Brugger SW, Davis MF, Torres EA, Gomez L, Li D, Lopez-Marte P, Daly MJ, Stevens C, Yang S, Sinha S, Mengesha E, Leavitt J, Damas OM, Quintero MA, Targan SR, Rabizadeh S, Sabic K, Cho JH, Abreu MT, McCauley JL, Haritunians T · PubMed 41661118

    Genetic admixture of United States Hispanic individuals provides a unique opportunity to examine ancestral origins of inflammatory bowel disease (IBD) risk. In ∼7.3K Hispanic participants (1660 IBD cases; 5614 controls), we examined ancestral heterogeneity of IBD clinical phenotypes and sought to identify IBD risk loci that displayed heterogeneity of effect or were ancestry-specific. Association of genetic ancestry with clinical phenotypes was evaluated. We conducted an ancestry-informed genome-wide (GW) association study for IBD, ulcerative colitis, and Crohn's disease (CD) to obtain ancestry-specific effect size estimates for alleles from African (AFR), European (EUR), and Amerindian (AIAN) origin. Ancestry-specific replication was assessed in All of Us Hispanic participants and transf

Discuss with your doctor

  • Genetic IBD risk and family history Moderate

    MTA3 rs111900950-A is associated with 12-fold increased inflammatory bowel disease risk in genome-wide studies

Screening

  • Monitor for inflammatory bowel disease symptoms Moderate

    Genetic predisposition increases IBD risk and warrants heightened awareness of disease symptoms
