MST1R and inflammatory bowel disease: Genes such as PARK7, CD40, NUCKS1, MST1R and SLC22A4, known to be associated with IBD (CD or UC) showed higher-end densities (Fig. 3).The number of SNPs mapped to a respective gene varied from 140 SNPs for the HLA-K gene to 2 SNPs for genes such as ZNF7 and TRPT1. The majority of genes had less than 20 SNPs, distance-wise mapped to them (Fig. 4b).
