Overall, the presence of this fusion transcript represents a highly significant novel association with the SHIP1-deficient phenotype, with a conservatively estimated odds ratio (OR) of 153.0 (95% CI: 5.562–4209, P < 0.0001) compared to the healthy 13 controls, and an OR of 606.3 (95% CI: 22.76–16,150, P < 0.0001) compared to all available SHIP1-sufficient IBD and healthy control subjects (n = 53). This evidence concerns the gene INPP5D and inflammatory bowel disease.
