Craniosynostosis refers to the early fusion of one or many cranial sutures, causing craniofacial abnormalities observed in 1:2,500 births worldwide. In most cases (85%), craniosynostosis is presented as sporadic anomaly (nonsyndromic craniosynostosis), while in other cases (15%) as part of syndromes (syndromic craniosynostosis). Patients with syndromic disorder usually have more severe symptoms compared to those with single suture synostosis. Most common syndromes of craniosynostosis include Pfeiffer, Apert, Crouzon, Jackson-Weiss, Muenke and Boston type MSX2-related syndrome. The main gene mutations in craniosynostosis involve FGFR1, FGFR2, FGFR3, TWIST1 and MSX2, which encode key factors influencing cranial bone morphogenesis. The main therapeutic approaches are surgical as discussed in this review, and the type of therapy depends on the graveness of the incident.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
