Abstract
AbstractDystrophic epidermolysis bullosa (DEB) is a rare, but severe, subtype of epidermolysis bullosa. It is characterized mainly by blisters and miliary rashes of the skin, while oral mucosa‐dominated cases are extremely rare. Here, we report the characteristics of oral mucosa lesions in a Chinese familial case of DEB with a novel compound heterozygous COL7A1 mutation. We further analyzed the genetic and molecular features of the proband and the two related mutation carriers. Our study further elucidates the genetic and phenotypic heterogeneity of DEB.
