Abstract

Genetic association studies have identified 215 risk loci for inflammatory bowel disease, thereby uncovering fundamental aspects of its molecular biology. We performed a genome-wide association study of 25,305 individuals and conducted a meta-analysis with published summary statistics, yielding a total sample size of 59,957 subjects. We identified 25 new susceptibility loci, 3 of which contain integrin genes that encode proteins in pathways that have been identified as important therapeutic targets in inflammatory bowel disease. The associated variants are correlated with expression changes in response to immune stimulus at two of these genes (ITGA4 and ITGB8) and at previously implicated loci (ITGAL and ICAM1). In all four cases, the expression-increasing allele also increases disease risk. We also identified likely causal missense variants in a gene implicated in primary immune deficiency, PLCG2, and a negative regulator of inflammation, SLAMF8. Our results demonstrate that new associations at common variants continue to identify genes relevant to therapeutic target identification and prioritization.

  • PLCG2 GOF polymorphisms have been recently associated with other disorders, such as inflammatory bowel disease and resistance of chronic lymphocytic leukaemia cells to the BTK inhibitor ibrutinib.

    “PLCG2 GOF polymorphisms have also been recently associated with other disorders, such as inflammatory bowel disease [114] and resistance of chronic lymphocytic leukaemia cells to the BTK inhibitor ibrutinib [99, 115]”

    From TREM2/PLCγ2 signalling in immune cells: function, structural insight, and potential therapeutic modulation (2021) · cites this paper as [114]

    The paper reports two likely functional PLCG2 missense variants associated with inflammatory bowel disease (section labelled Abstract; page unavailable). It does not establish that those IBD-associated variants are gain-of-function. The ibrutinib-resistance clause has separate citations and is not attributed to this paper. (LLM, conf=0.88)

  • This convergence and enrichment provides reassurance that genetic associations will coalesce around molecular and cellular processes with a core role in pathogenesis.

    “This provides reassurance that, even as the number of association signals for a given disease proliferates, the genetic associations uncovered will coalesce around molecular and cellular processes with a core role in pathogenesis62,63.”

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
