DefinitionThis section has been translated automatically.
The Cooks syndrome, an autosomal dominant malformation syndrome (ORPHA1487) has only been described in about 20 patients.
The nail abnormalities range from onychodystrophy (dystrophic nails) to anonychia (missing nails). At the same time there is brachydactyly (shortening) of the little finger and digitalization (triphalangia) of the thumb. The end phalanges of the fingers and toes are either hypoplastic or missing completely.
