We also observed that the cis-regulatory network of SLC24A4 (Fig. 5g), 46 kb from a risk single nucleotide polymorphism (SNP) rs11626366 (P = 7.4 × 10−3), is specifically dense in the IBD-relevant cell types, which shows the complex regulatory landscape of disease genes across different cell types. This evidence concerns the gene SLC24A4 and inflammatory bowel disease.
