Transient bullous dermolysis of the newborn: a novel de novo mutation in the COL7A1 gene

摘要

BackgroundBullous dermolysis of the newborn (BDN), an extremely rare clinical type of dystrophic epidermolysis bullosa (DEB), is characterized by subepidermal blistering at birth or shortly thereafter, followed by rapid improvement with minimal scarring or pigmentation. A total of 38 cases have been reported in the literature since the disease was initially described in 1985, but only 14 mutations in COL7A1, the gene responsible for the disease, have been detected in families with BDN.
