Pfeiffer's syndrome (Rudolf Arthur Pfeiffer)

Related people

A congenital syndrome characterized by craniostenosis resulting from premature cranialseam-synostosis, abnormal skull shape, antimongoloid palpebrae, small nose, narrow maxillae, gothic palate, syndactyly of hands and feet, and broad thumbs and great toes. Normal intelligence. The synonym is variously classified as acrocephalosyndactyly IV (Spranger, Langer, and Wiedemann), acrocephalosyndactyly V (McKusick), and, occasionally, acrocephalosyndactyly VI. Inheritance is autosomal dominant. Variable expresssivity and a high portion of new mutations.

Rudolf A. Pfeiffer in 1964 described a family. The family previously described by Noack in 1959 was erroneously classified as Apert’s syndrome.
