The craniosynostosis syndromes are a group of disorders sharing the premature fusion of one or more sutures of the skull. Often additional anomalies are associated. There are eight craniosynostosis disorders caused by mutations in three fibroblast growth factor receptor genes: FGFR1, FGFR2 and FGFR3. All are autosomal dominant. Penetrance varies with the specific craniosynostosis type. Many FGFR mutations are associated with advanced paternal age.
