In the International IBD Genetics Consortium meta-analysis for CD and UC, no associated SNPs in IL-33 were reported, while the rs10758669 variant (position 4971602) of JAK2 was identified as a CD and UC risk locus (CDmetaP = 1.00×10−13, UCmetaP = 8.52×10−13) [36]. This evidence concerns the gene JAK2 and inflammatory bowel disease.
