In addition, several of these genes are acknowledged IBD-susceptibility genes or are localized at replicated risk loci identified by GWAS (eg. ATG16L1, IL10, IL12B, JAK2, ARPC2, PTGER4, ZNF365, NKX2-3, PTPN2, PTPN22, C11orf30, ORMDL3, STAT3 (Table S8). Here, PTGER4 is linked to inflammatory bowel disease.
