Familial Behcet-like autoinflammatory disease-3 (AIFBL3) is an autosomal dominant disorder characterized predominantly by chronic mucocutaneous ulceration (summary by Lecerf et al., 2023). For a general phenotypic description and a discussion of genetic heterogeneity of AIFBL, see AIFBL1 (616744).

Inflammatory bowel disease-30 (IBD30) is characterized by abdominal pain and watery or bloody diarrhea, with changes in the intestinal tract consistent with Crohn disease (Mao et al., 2018). For a general description and a discussion of genetic heterogeneity of inflammatory bowel disease, including Crohn disease (CD) and ulcerative colitis (UC), see IBD1 (266600).
