Interestingly, the human homologs of eight of these RM Runx3 high-confidence target genes, CD300LF, CFB, IFIH1, IL10, NOS2, PLAU, PRDX5 and TNF, harbored SNPs that are susceptibility loci for IBD, Crohn’s disease (CD) and/or ulcerative colitis (UC) (S1 Table sheet 2). Here, PRDX5 is linked to Crohn disease.
