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
Caroli disease an autosomal recessive trait. Females are more prone to Caroli disease than males. Family history may include kidney and liver disease due to the link between Caroli disease and ARPKD. "PKHD1", the gene linked to ARPKD, has been found mutated in patients with Caroli syndrome. "PKHD1" is expressed primarily in the kidneys with lower levels in the liver, pancreas, and lungs, a pattern consistent with phenotype of the disease, which primarily affects the liver and kidneys. The genetic basis for the difference between Caroli disease and Caroli syndrome has not been defined. Modern imaging techniques allow the diagnosis to be
