Description : Pfeiffer syndrome is an autosomal dominant craniosynostosis syndrome with characteristic
anomalies of the hands and feet. Three clinical subtypes, which have important diagnostic
and prognostic implications, have been identified (Cohen, 1993). Type 1, the classic
syndrome, is compatible with life and consists of craniosynostosis, midface deficiency,
broad thumbs, broad great toes, brachydactyly, and variable syndactyly. Type 2 consists
of cloverleaf skull with Pfeiffer hands and feet, together with ankylosis of the elbows.
Type 3 is similar to type 2 but without cloverleaf skull. Ocular proptosis is severe,
and the anterior cranial base is markedly short. Various visceral malformations have
been found in association with type 3. Early demise is characteristic of types 2 and
3. Cohen and Barone (1994) further tabulated the findings in the 3 types of Pfeiffer
syndrome.;
