    Inflammatory bowel disease (IBD) includes Crohn’s disease (CD) and ulcerative colitis (UC), which exhibit clinical heterogeneity despite shared genetic backgrounds.

  • 2

    Strong genetic correlations were found among overall IBD, CD, and UC, indicating significant shared genetic liability across these conditions.

  • 3

    MAGMA and PoPS analyses identified immune-inflammatory candidates such as IL23R, JAK2, and NOD2 as prioritized genes linked to IBD susceptibility.

  • 4

    Adult disease-tissue spatial mapping revealed significant enrichment of IBD genetic signals in immune-rich and epithelial-inflammatory lesion contexts.

  • 5

    The study emphasizes the importance of spatially resolved genetic mapping to understand how inherited IBD susceptibility manifests in adult lesions.
