[Dyskeratosis follicularis].

Dyskeratosis follicularis (or Darier's disease) is a genetic skin disease with an autosomal dominant inheritance and a prevalence of 1:100,000-1:35,000. Mutations in the gene ATP2A2 encoding the Ca2+-ATPase SERCA2 in the endoplasmatic reticulum lead to acantholysis and dyskeratosis in the epidermis, nails and mucosal membranes with resultant brown-yellow coloured, often infested skin papules and nail changes. The newly established Danish database for genodermatoses is embarking on an extensive registration of all Danish patients with Darier's disease. Hopefully, the establishment of this database will lead to better research and the formation of a patient association.
