Pfeiffer syndrome is caused by mutations in the fibroblast growth factor receptors FGFR1 and FGFR2. The syndrome is grouped into three types: type 1 (classic Pfeiffer syndrome) is milder and caused by mutations in either gene; types 2 and 3 are more severe, often leading to death in infancy, caused by mutations in FGFR2 .
FGFR2 mutations are the cause of several craniosynostosis syndromes: Acrocephalosyndactyly type 1 (Apert syndrome) Beare-Stevenson cutis gyrata syndrome; Crouzon syndrome; Jackson-Weiss syndrome; Pfeiffer syndrome; Cancer
Currently, Noack syndrome (ACPS type I) is now classified as Pfeiffer syndrome (ACS type V); Goodman syndrome (ACPS type IV) is classified as a variation of Carpenter syndrome (ACPS type II); and different researchers have combined Apert (ASC type I), Crouzon (ASC type II), and Pfeiffer (ASC type V) syndrome into Apert-Crouzon and Crouzon ...
The syndrome is caused by a mutation in a gene on chromosome 10 that controls the body's production of fibroblast growth factor receptor 2 (FGFR2). Crouzon syndrome is named for Octave Crouzon, a French physician who first described this disorder.
Carpenter syndrome, also called acrocephalopolysyndactyly type II, is an extremely rare autosomal recessive congenital disorder characterized by craniofacial malformations, obesity, syndactyly, and polydactyly.
Marfan syndrome is caused by mutations in the FBN1 gene on chromosome 15, which encodes fibrillin 1, a glycoprotein component of the extracellular matrix. Fibrillin-1 is essential for the proper formation of the extracellular matrix, including the biogenesis and maintenance of elastic fibers.
An activating mutation in FGFR1 viz., P232R (proline-to-arginine substitution in the protein's 232nd amino acid), is responsible for the Type 1 or classic form of Pfeiffer syndrome, a disease characterized by craniosynostosis and mid-face deformities. A tyrosine-to-cysteine substitution mutation in the 372nd amino acid of FGFR1 (Y372C) is ...
Atelosteogenesis type I is a rare autosomal dominant condition. This condition is evident at birth and is associated with a very poor prognosis for the baby. It may be diagnosed antenatally.
Cardiocranial syndrome, Pfeiffer type is a rare multiple disorder syndrome characterized by congenital heart defects, sagittal craniosynostosis, and severe developmental delay. The condition has been reported in less than 10 patients worldwide.
Timothy syndrome has an autosomal-dominant pattern of inheritance. There are two recognized types of Timothy syndrome, classical (type-1) and a second type (type-2). They are both caused by mutations in CACNA1C, the gene encoding the calcium channel Ca v 1.2 α subunit.
