Dystrophic epidermolysis bullosa is caused by mutations of the type vii collagen gene epidermolysis bullosa is a lifelong disease some subtypes, especially the milder forms, improve with age.

Background recessive dystrophic epidermolysis bullosa (rdeb) is an incurable disease caused by mutations in the gene encoding type vii collagen, the major component of anchoring fibrils (af) we previously demonstrated that gentamicin produced functional type vii collagen in rdeb cells harboring . In the absence of mutations of the col7a1 gene, an autoimmune response against type vii collagen can result in an acquired form of epidermolysis bullosa called epidermolysis bullosa acquisita. The blisters are caused by abnormalities of the anchoring fibrils, which are made up of type vii collagen, that attach the epidermis to the underlying dermis mutations in the col7a1 gene can be autosomal dominant or recessive, and the blisters leave scars.

Mutations in the gene col7a1 encoding type vii collagen cause dystrophic epidermolysis bullosa, a clinically heterogeneous autosomal dominant or recessive blistering disorder of the skin and mucous membranes. 1 department of medicine, division of dermatology, university of southern california, crl 204, 1303 mission road, los angeles, california 90033, usa 2 departments of pathology and biochemistry . Deb is derived from mutations in the type vii collagen gene (col7a1), encoding a large collagenous protein that is the predominant, if not exclusive, component of the anchoring fibrils at the dermal–epidermal junction.

Recessive dystrophic epidermolysis bullosa (rdeb) is a devastating inherited skin blistering disease caused by mutations in the col7a1 gene that encodes type vii collagen (c7), a major structural component of anchoring fibrils at the dermal‐epidermal junction (dej). Dystrophic epidermolysis bullosa is due to mutation involving collagen vii understanding the molecular basis of the disease has a significant impact in diagnosis, counselling, prenatal and preimplantation testing, and opens up the possibility of gene therapy.
