BZW2 and inflammatory bowel disease: Among the genes mapped in the suggestive loci, we found genes previously linked to IBD and its subtypes (such as IL23R, JAK2 or genes located in HLA region), as well as genes not previously associated to IBD or its subtypes, including among others, AGT, BZW2 or FSTL1 genes, located on loci where the lead SNP had an OR of 2.0 (95% of confidence interval of 1.5–2.7), 3.2 (2.1–5.1) and 1.5 (1.3–1.8), respectively (Table 2).
