A new pathogenic keratin 5 mutation in a Hindoestan family with localized epidermolysis bullosa simplex.
Epidermolysis bullosa simplex is an autosomal dominant inherited skin blistering disorder caused by mutations in the genes KRT5 or KRT14 coding for the basal epidermal keratins 5 and 14, respectively. We describe a novel heterozygous pathogenic missense mutation (KRT5:c.596A>T, p.Lys199Met) in a Hindoestan male with early onset localized epidermolysis bullosa simplex that segregated with the phenotype in the family. We also found a new heterozygous amino acid substitution polymorphism in the variable keratin 14 N-terminal head domain (KRT14:c.88C>T, p.Arg30Cys), that did not segregate with the phenotype.
