Ectodermal dysplasia-skin fragility syndrome: a novel mutation in the PKP1 gene

Summary Ectodermal dysplasia–skin fragility syndrome (EDSFS) is an autosomal recessive genodermatosis characterized by skin fragility, palmoplantar hyperkeratosis, onichodystrophy, perioral fissuring and noncicatricial alopecia. It is caused by plakophilin‐1 (PKP1) deficiency, which results in desmosomal abnormality and poor intercellular cohesion between the epidermal cells. We report a case with a novel PKP1 mutation in intron 6.
