Dystrophic epidermolysis bullosa is caused by mutations in the COL7A1 gene. The disease characterized clinical heterogeneity. To date, scientific findings allow to evaluate correlations between severity of manifestations and genetic defects underlying development disease. A systematic literature search was performed using PubMed RSCI, keywords including dystrophic bullosa, collagen VII, COL7A1....

Epidermolysis bullosa (EB) is a genetically and clinically variable disease characterized by blis‐ ter formation and erosions of the skin and mucous membranes after minor trauma [1]. The in‐ heritance of the affected genes can occur in a dominant or recessive way depending on the subform of the disease. In general, epidermolysis bullosa is caused by mutations in genes en‐ coding structural prot...

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.

Dominant-negative interference by glycine substitution mutations in the COL7A1 gene causes dominant dystrophic epidermolysis bullosa (DDEB), a skin fragility disorder with mechanically induced blistering. Although qualitative and quantitative alterations of the COL7A1 gene product, collagen VII, underlie DDEB, the lack of direct correlation between mutations and the clinical phenotype has rende...

Patients with the genetic skin blistering disease recessive dystrophic epidermolysis bullosa (RDEB) develop aggressive cutaneous squamous cell carcinoma (cSCC). Metastasis leading to mortality is greater in RDEB than in other patient groups with cSCC. Here we investigate the dermal component in RDEB using mRNA expression profiling to compare cultured fibroblasts isolated from individuals withou...

Epidermolysis bullosa pruriginosa (EBP) is a rare subtype of dystrophic epidermolysis bullosa (DEB) characterized by intense pruritus, nodular or lichenoid lesions, and violaceous linear scarring, most prominently on the extensor extremities. Remarkably, identical mutations in COL7A1, which encodes an anchoring fibril protein present at the dermal-epidermal junction, can cause both DEB and EBP ...

Dystrophic epidermolysis bullosa (DEB) pruriginosa (DEB-Pr) is a rare variant of DEB due to COL7A1 dominant and recessive mutations, which is characterized by severe itching and lichenoid or nodular prurigo-like lesions, mainly involving the extremities. Less than 30 patients have been described showing variable disease expression, and frequently, delayed age of onset. We report the clinical an...

Functional impairment or complete loss of type VII collagen, caused by mutations within COL7A1, lead to the severe recessive form of the skin blistering disease dystrophic epidermolysis bullosa (RDEB). Here, we successfully demonstrate RNA trans-splicing as an auspicious repair option for mutations located in a wide range of exons by fully converting an RDEB phenotype in an ex vivo pre-clinical...

ISSN 0001-5555 Dystrophic epidermolysis bullosa (DEB) is a group of hereditary bullous dermatoses caused by mutations in the COL7A1 gene (reviewed in (1)). In autosomal recessive DEB (RDEB) with severe generalised phenotypes, non-sense, frame-shift, indels or splice-site mutations predicting bi...

BACKGROUND One of the unique characteristics of the female genital tract is the extensive tissue remodeling observed throughout the menstrual cycle. Multiple components of the extracellular matrix take part in this tissue rebuilding; however, the individual components involved have not been identified. METHODS In the present study, the expression of extracellular matrix proteins and selected ...
