Important monogenic cause of VEOIBD (recognised criteria for the R15 panel). In a retrospective case series, 9 of 57 (16%) children with recessive DEBP had diarrhoea with macroscopic/microscopic features of colitis (PMID: 18363753). There is additionally a recognised association between Epidermolysis Bullosa Acquisita (an autoimmune condition directed against Type VII Collagen (the COL7A1 protein product) (PMID: 23517353). Included on a monogenic IBD gene panel proposed by The Paediatric IBD Porto Group of ESPGHAN (PMID: 33346580). Not a recognised cause of immunodeficiency.
