Crouzon syndrome is an autosomal dominant disorder characterized by craniosynostosis that causes secondary alterations of the facial bones and facial structure. [1 2] It is one of the craniosynostosis syndrome that is caused by a mutation in the fibroblast growth factor receptor 2 gene (FGFR2). See our Privacy Policy and User Agreement for details. Crouzon syndrome was first discovered in 1912 as one of the types of craniofacial dysotosis. It is intended to provide a clearer understanding of the condition for patients, parents and others. This early fusion prevents the skull from growing normally and affects the shape of the head and face. Surgery to correct deficiencies can not only help your child achieve a more normal appearance, but can also prevent an unusual closing of the skull that could hamper brain development. CROUZON syndrome is an inherited syndrome of Craniofacial Dysmorphology or abnormal craniofacial appearance, which was originally described in 1912 and is now well recognised. Research has identified the affected genes as the Fibroblast Growth Factor Receptor 2 (FGFR2) gene and FRGR3. Crouzon syndrome is a rare disorder, which affects about 1.6 per 100,000 persons, and about 4.5% among the subjects of craniosynostosis disorder. You can change your ad preferences anytime.

Crouzon syndrome is a genetic disorder characterized by the premature fusion of certain skull bones (craniosynostosis). Crouzon Syndrome is a rare genetic disorder resulting from a mutation of the Fibroblast Growth Factor Receptor 2 Gene. Specifically, this syndrome affects the first branchial (or pharyngeal) arch, which is the precursor of the maxilla and mandible.Since the branchial arches are important developmental features in a growing embryo, disturbances in their development create lasting and widespread effects. • Approximately 30% of individuals with Crouzon syndrome develop hydrocephalus, • Sensorineural hearing loss • Crouzon syndrome is also associated with patent ductus arteriosus (PDA) and aortic coarctation.
