Description : In a review of ectodermal dysplasia syndromes characterized by palmoplantar keratoderma
(PPK) and congenital alopecia, Castori et al. (2010) suggested that there are 2 main
types of unclassified syndromes that combine these 2 features. A more severe recessive
disorder shows progressive hyperkeratosis resulting in sclerosis, severe contractures
and tapering of the digits, and pseudoainhum formation. The less severe autosomal
dominant disorder (104100) does not have significant hand complications, although
keratosis is present.;
