A meta-analysis of fifteen GWAS and additional Immunochip data revealed 163 loci related to European lineage IBD (30 loci specific for CD, 23 loci specific for UC, and 110 loci for both diseases), including genes, such as NOD2 and ATG16L1 that were correlated with CD only, extracellular matrix protein 1 (ECM1) and IL10 that were correlated with UC only, and IL23R that correlated with both diseases [32]. This evidence concerns the gene ECM1 and inflammatory bowel disease.
