Case report. Novel and recurrent COL7A1 mutations in Chinese patients with dystrophic epidermolysis bullosa pruriginosa.
Dystrophic epidermolysis bullosa pruriginosa (DEB-Pr) is a rare subtype of dystrophic epidermolysis bullosa (DEB). This disease is characterized by severe itching, lichenoid nodules or prurigo-like lesions, and linear scarring with a predilection for the extensor limbs. Pathogenic mutations in the type VII collagen alpha 1 (COL7A1) gene have been identified. We analyzed mutations in the COL7A1 ...
متن کاملPretibial dystrophic epidermolysis bullosa*
Epidermolysis bullosa is a group of mechano-bullous genetic disorders caused by mutations in the genes encoding structural proteins of the skin. Dystrophic epidermolysis bullosa is caused by mutations in the COL7A1 gene encoding collagen VII, the main constituent of anchoring fibrils. In this group, there are autosomal dominant and recessive inheritances. The pre-tibial form is characterized by...
متن کاملIdentification of mutations in the COL7A1 gene in a proband with mild recessive dystrophic epidermolysis bullosa and aortic insufficiency.
We report the clinical and molecular findings in a patient with a mild form of recessive dystrophic epidermolysis bullosa and aortic insufficiency. To our knowledge, this is the first report of association between dystrophic epidermolysis bullosa and abnormalities of the aortic valve. Analysis of the COL7A1 gene has revealed two new mutations, a 20-bp duplication and a splice site mutation.
متن کاملUse of type VII collagen gene (COL7A1) markers in prenatal diagnosis of recessive dystrophic epidermolysis bullosa.
Generalised recessive dystrophic epidermolysis bullosa (EB) is a severe inherited disease in which patients suffer from blistering and scarring of the skin and mucous membranes after minor mechanical trauma. Tight genetic linkage has been established to the type VII collagen gene (COL7A1) at 3p21, with no evidence of locus heterogeneity. Several COL7A1 mutations have now been identified in rece...
متن کاملJunctional and Dystrophic Epidermolysis Bullosa
Epidermolysis bullosa (EB) is a congenital genodermatosis, which affects mainly skin and occasionally other organs [1]. Lifelong blistering and erosion of the skin and mucous membrane, caused by mechanical trauma, threaten EB patients [1]. The most common cause of death is metastasizing squamous cell carcinoma [2]. EB is subdivided into mainly three categories by the location of tissue separati...
