Autosomal dominant hypodontia with nail dysplasia – http://id.who.int/icd/entity/317823248

Hypodontia-nail dysplasia syndrome is a form of ectodermal dysplasia characterised by usually normal primary teeth with permanent teeth that often fail to erupt. The mandibular incisors, second molars, and maxillary canines are frequently absent and the crowns may be small and conical. Lip eversion may be present. Nails are usually small, thin and brittle with longitudinal ridges, pitting and koilonychias. Congenital absence of the nail plate has also been reported. Toenails are usually more severely affected than fingernails.
