Abstract

Summary We report a Japanese case of dominant dystrophic epidermolysis bullosa with a de novo mutation in the triple-helical domain of the type VII collagen. Mutation detection revealed a glycine → aspartic acid substitution at amino acid position 2012 in exon 73 (G2012D). This previously unreported mutation underlies a clinical phenotype of moderately severe, localized skin blistering.
