Inflammatory Bowel Diseases: the genetic revolution

Gastroenterol Clin Biol. 2009 Jun:33 Suppl 3:S123-30. doi: 10.1016/S0399-8320(09)73147-1.

Abstract

The genetic component of Inflammatory Bowel Diseases is among the best known for complex genetic disorders. If the functional candidate gene approach was rarely fruitful in the past, genome-wide scans allowed finding several susceptibility genes for Crohn disease including NOD2, IL23R, ATG16L1, IRGM, TNFSF15, a region close to PTGER4, PTPN2, PTPN22, NKX2-3 and many others. Only one gene, ECM1, has been reported for ulcerative colitis alone. We now need to further explore these new genes before to understand their biological role. However they clearly demonstrate the importance of innate immunity and autophagy for Crohn's disease and of the TH-17 differentiation for ulcerative colitis, Crohn's disease and other inflammatory disorders.
