Description : Epidermolysis bullosa dystrophica is a clinically heterogeneous disorder characterized by blistering and scarring of the skin and mucous membranes in response to mechanical force. Microscopic examination of the skin shows cleavage below the basement membrane within the papillary dermis. All forms are caused by mutation in the COL7A1 gene. Fine et al. (2000) proposed that the Cockayne-Touraine and Pasini subtypes of dystrophic epidermolysis bullosa be combined into 1 category known as 'dominant dystrophic epidermolysis bullosa' (DDEB), since both are caused by mutations in the COL7A1 gene and show overlapping clinical features. Epidermolysis bullosa simplex (see, e.g., 131800) and epidermolysis bullosa junctional (see, e.g., 226700) are clinically and genetically distinct disorders characterized by tissue separation at the levels of the basal keratinocyte layer and lamina lucida, respectively.;

Inheritance : Autosomal dominant;

Molecular basis : Caused by mutation in the collagen type VII, alpha-1 gene (COL7A1, 120120.0002).;

Prefixed ID : #131750;
