[1 2] It is one of the craniosynostosis syndrome that is caused by a mutation in the fibroblast growth factor receptor 2 gene (FGFR2). January 2013; Nobel medicus 9(1):110-112 Crouzon syndrome is different from other craniosynostosis syndromes because it does not cause abnormalities in hands and legs. This means that having a change (mutation) in only one copy of the responsible gene in each cell is enough to cause features of the condition.There is nothing that either parent can do, before or during a pregnancy, to cause a child to be born with Crouzon syndrome.

[] Indeed, mutations in the FGFR2 gene have been detected in more than 50% of patients with Crouzon syndrome. Children who have Crouzon syndrome have a range of problems of variable severity, from mild facial symptoms of a mainly cosmetic nature to symptoms affecting breathing, feeding, vision and brain development. The main presenting feature of this syndrome is craniofacial synostosis but multiple physical dysmorphic features have been reported.

Crouzon syndrome is a genetic condition, caused by a mutation (change) on a specific gene. Crouzon syndrome is classified as one of the rare inherited disorders whereby a variety of the sutures (flexible seams) in the skull of a baby fuses or turn into bone too early. In Crouzon syndrome brachycephaly (widened and shortened) is the most common presentation due to bi-coronal suture fusion. Craniosynostosis syndromes are a set of genetic disorders that are characterized by the premature fusion of cranial sutures which can impair proper brain and craniofacial development from irregular bone formation . Crouzon syndrome is a kind of Craniofacial Dysostosis. 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. 3.

Crouzon syndrome is a rare birth defect that causes premature fusion (closing) of several sutures (joints) in a baby’s skull. Primarily characterized by premature closure of the fibrous joints (cranial sutures) between certain bones in the skull (craniosynostosis) and distinctive facial abnormalities. It also causes bones in the face not to grow forward, resulting in malformed eye sockets and a large forehead. (1959) described 3 patients with typical Crouzon disease; 2 of these had a positive family history and one was … Cases of Autosomal recessive inheritances have also been described.

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. Craniosynostosis is a malformation that involves the early closure of a single or multiple sutures of the skull. Infants have sutures between the bones in the face and skull. Common features include hypertelorism, exophthalmos and external strabismus, parrot-beaked nose, short upper lip, hypoplastic maxilla, and a relative mandibular prognathism. It has incidence of approximately 16.5 cases per million live births. The features of the syndrome are distinct and visible.
