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
Paget's disease of bone percent of people with Paget's disease also have a family member with the disease. In cases where the disease is familial, it is inherited in an autosomal dominant fashion, although not all people that inherit the affected version of the genes will express the disease (incomplete penetrance). The incidence of Paget's disease varies considerably with geographic location. Paget's predominantly affects people of European descent, whereas people of African, Asian, or Indian descent are less commonly affected. Paget's disease is less common in Switzerland and Scandinavia than in the rest of Western Europe. Paget's disease is uncommon in the native populations
