Very early onset inflammatory bowel disease hand, other types of primary immunodeficiency can often manifest with IBD-like symptoms, too. These include the IPEX syndrome, Wiskott-Aldrich syndrome, XIAP syndrome or chronic granulomatous disease. Inflammatory bowel diseases (IBDs), such as Crohn Disease (CD) or Ulcerative Colitis (UC), are chronic inflammatory conditions of the gastrointestinal tract. Up-to-date findings show that the pathogenesis is influenced by both environmental and genetic factors. A considerable number of monogenic disorders can be found especially among patients with VEOIBD. Causal mutations can be found in genes involved in epithelial barrier formation (COL7A1, FERMT1), innate (CYBB, G6PC3), as well as the specific immune response and
Pancreatic disease due to a lack of digestive enzymes made by the pancreas. EPI is found in humans afflicted with cystic fibrosis and Shwachman–Diamond syndrome. It is caused by a progressive loss of the pancreatic cells that make digestive enzymes. Chronic pancreatitis is the most common cause of EPI in humans. Loss of digestive enzymes leads to maldigestion and malabsorption of nutrients. Cystic fibrosis, is a hereditary disease that affects the entire body, causing progressive disability and early death. It is caused by a mutation in the cystic fibrosis transmembrane conductance regulator (CFTR) gene. The product of this gene helps create sweat,
