Ostrowski et al. identified a group of 15 genes (ANOS1, ANXA3, ATP9A, CACNA1E, COX6B2, FCGR1B, GALNT14, IL18R1, ITGB4, KLRF1, MMP9, OPLA, PFKFB3, S100A12, and UTS2R) in peripheral blood with the potential to discriminate between children with clinically active IBD and healthy donors, but not between adults with IBD and healthy donors [110]. This evidence concerns the gene S100A12 and inflammatory bowel disease.
