A 3 mm wide circular CSD was created in two murine models of Crouzon syndrome: (i) surgical control (CSDs without TNT/Ti or any protein, n=6) and (ii) experimental groups with TNT/Ti loaded with GPC3, further subdivided into the presence or absence of chitosan coating (on nanotubes) (n=12 in each group).
All affected offspring were shown to be carriers of a partial trisomy of chromosome 14 including the FGFR2 gene, which is associated with various dominant inherited craniofacial dysostosis syndromes in man, and partial monosomy of chromosome 8 containing MSX1 known to be associated with tooth agenesis and orofacial clefts in other species.

From June 2013 to February 2015, a total of nine children with Crouzon syndrome underwent Le Fort III distraction osteogenesis with a rigid external distraction device (RED device, KLS Martin, Tuttlingen, Germany).

Despite long axial lengths, shallow anterior chambers with occluded angles are possible in Crouzon syndrome and are most likely caused by FGFR2-related anterior segment dysgenesis.
Fibroblast growth factor receptor 2 (FGFR2) <sup>C342Y/+</sup> mutation is a known cause of Crouzon syndrome that is characterised by craniosynostosis and midfacial hypoplasia.
These findings expand the mutation spectrum of FGFR2, and are valuable for genetic counseling in addition to prenatal diagnosis in patients with Crouzon syndrome.
The craniofacial features in this case were in keeping with a diagnosis of Crouzon syndrome which was confirmed by molecular testing of the FGFR2 gene.
In this study, we analyzed FGFR1-3 genes in four patients with Crouzon syndrome (CS), four patients with Pfeiffer syndrome type 2 (PS-2), one patient with Jackson-Weiss syndrome (JWS), and two patients (sisters) with Muenke syndrome (MS).
The purpose of the present study was to investigate the fibroblast growth factor receptor 2 (FGFR 2) gene in two Chinese families with Crouzon syndrome and to characterize the associated clinical features.
We measured the foramen magnum area (FMA) and its sagittal and transversal components: the right, left, and mean area of the jugular foramen; the posterior fossa volume; and the cerebellar volume on preoperative millimetric computed tomography scan slices in 31 children with an FGFR2 mutation (14 with Crouzon syndrome, 11 with Apert syndrome, and 6 with Pfeiffer syndrome).
