Crouzon syndrome is a rare genetic disorder that may be evident at birth (congenital) or during infancy. The disorder is characterized by distinctive malformations of the skull and facial (craniofacial) region. Such abnormalities may vary greatly in range and severity from case to case, including among affected family members. However, in most infants with Crouzon syndrome, the fibrous joints between certain bones of the skull (cranial sutures) close prematurely (craniosynostosis). In addition, facial abnormalities typically include unusual bulging or protrusion of the eyeballs (proptosis) due to shallow eye cavities (orbits); outward deviation of one of the eyes (divergent strabismus or exotropia); widely spaced eyes (ocular hypertelorism); and a small, underdeveloped upper jaw (hypoplastic maxilla), with protrusion of the lower jaw (relative mandibular prognathism).
In some instances, Crouzon syndrome is inherited as an autosomal dominant trait. In other cases, affected individuals have no family history of the disease. In such instances, Crouzon syndrome is thought to result from new genetic changes (mutations) that occur randomly for unknown reasons (sporadically).
