LY9 and inflammatory bowel disease: Thus, GWAS-identified IBD-associated SNPs are located within ITLN1 and its flanking regions, and these SNPs are in LD with SNPs in CD244 and Ly9, which are genes located 3’ to ITLN1. Data in the GTEx browser revealed that quantitative trait loci (QTL) for expression (eQTL) in blood for ITLN1 and CD244 are both affected by several disease risk SNPs, including rs1333062, rs2274907 and rs2297559 (Supplemental Table 3)36.
