In the UKB data, the IBD risk allele of rs3024493 is the top cis pQTL for IL-10 and associates with lower plasma level of IL-10 (P = 1.4 × 10−52, effect = −0.14 s.d., PP = 0.98), but not with any other protein measured using Olink (Fig. 4). This evidence concerns the gene IL10 and inflammatory bowel disease.
