A novel glycine mutation in the COL7A1 gene leading to dominant dystrophic epidermolysis bullosa with intra-familial phenotypical heterogeneity.
Dystrophic epidermolysis bullosa (DEB) represents a group of inherited skin disorders characterized by sublamina densa blister formation. We resent the case of a 16-year old girl with DEB, who had a 10-year-history of recurrent pruritic skin lesions. Despite misleading biopsy results, the correct diagnosis was suspected by examination of other family members. Finally, mutational analysis revealed a novel glycine substitution mutation in the COL7A1 gene in three affected family members.
