1. Comparison of periodontal parameters in individuals with syndromic craniosynostosis
Craniosynostosis syndromes are characterized by premature closure of one or more cranial sutures, associated with other malformations, the most frequent of which are the Crouzon and Apert syndromes. Few studies in the literature have addressed the oral health of these individuals. The purpose of this study was to compare the periodontal status of individuals

2. "Condições bucais de pacientes com craniossinostoses múltiplas sindrômicas e síndrome de Treacher Collins." / "Oral health status of patients with syndromic craniosynostosis and Treacher Collins syndrome."
Two groups of patients were evaluated in an attempt to achieve more information on the oral health status, association with cleft lip and palate, soft tissue alterations and prevalence of dental anomalies in patients with craniofacial syndromes. One group comprised 19 patients with craniosynostosis syndromes (Apert, Crouzon, Pfeiffer and Saethre-Chotzen synd

3. Variable expression in Pfeiffer syndrome.
A female infant with Pfeiffer syndrome (acrocephalosyndactyly V) is presented. Her mother has no limb malformations, but has craniofacial features with strongly suggest that she is also affected, although more mildly. This family indicates that wide intrafamilial variation of Pfeiffer syndrome is possible and suggests that without detailed investigation mild
4. Pitfalls of genetic counselling in Pfeiffer's syndrome.
A family with Pfeiffer's syndrome is presented in which members of two generations showed only partial but relevant syndactyly before a child was born, in the third generation, with the full acrocephalosyndactyly syndrome.
5. Pfeiffer type cardiocranial syndrome: a third case report.
Pfeiffer-type cardiocranial syndrome is a rare condition reported previously in three patients, two of whom were sibs. All three patients shared features that included growth and developmental retardation, sagittal synostosis, hypertelorism, low set ears, micrognathia with mandibular ankylosis, congenital heart defects, and genital anomalies. The purposes of
6. Pfeiffer's type of acrocephalosyndactyly in two families
Two additional families with Pfeiffer's syndrome are reported in which the wide variability of gene expression is demonstrated.
7. Pfeiffer syndrome: report of a family and review of the literature.
A 5-year-old boy and his father with Pfeiffer syndrome are described. They had acrocephaly, hypertelorism, antimongoloid slant of the palpebral fissures, protrusion of the eyes, large and broad nose, small mandible, irregularly placed teeth, additional upper canine, high-arched palate, partial syndactyly of fingers and toes, brachydactyly of toes, valgus def
8. A splicing switch and gain-of-function mutation in FgfR2-IIIc hemizygotes causes Apert/Pfeiffer-syndrome-like phenotypes
Intercellular signaling by fibroblast growth factors plays vital roles during embryogenesis. Mice deficient for fibroblast growth factor receptors (FgfRs) show abnormalities in early gastrulation and implantation, disruptions in epithelial–mesenchymal interactions, as well as profound defects in membranous and endochondrial bone formation.

9. A family study of craniosynostosis, with probable recognition of a distinct syndrome.
A family study was based on 184 consecutive patients who had undergone surgery for craniosynostosis at The Hospital for Sick Children, London, between 1953 and 1976. Of these, 127 were traced and visited and are the probands for this study. Crouzon syndrome was recognised in 16, Apert in 11, Saethre-Chotzen in nine, and Pfeiffer in two. In addition, two prob
10. Presence of the Apert canonical S252W FGFR2 mutation in a patient without severe syndactyly.
Apert syndrome, characterised by craniosynostosis, craniofacial anomalies, and symmetrical syndactyly of the digits (cutaneous and bony fusion), has been associated with two canonical mutations in the FGFR2 gene (S252W, P253R) in the great majority of cases. Since these two alterations have been observed exclusively among these patients, it has been suggeste
11. Craniosynostosis associated with FGFR3 pro250arg mutation results in a range of clinical presentations including unisutural sporadic craniosynostosis.
Several mutations involving the fibroblast growth factor receptor (FGFR) gene family have been identified in association with phenotypically distinct forms of craniosynostosis. One such point mutation, resulting in the substitution of proline by arginine in a critical region of the linker region between the first and second immunoglobulin-like domains, is as
12. Constitutive receptor activation by Crouzon syndrome mutations in fibroblast growth factor receptor (FGFR)2 and FGFR2/Neu chimeras.
Crouzon syndrome is an autosomal dominant condition primarily characterized by craniosynostosis. This syndrome has been associated with a variety of amino acid point mutations in the extracellular domain of fibroblast growth factor receptor 2 (FGFR2). FGFR2/Neu chimeras were generated by substituting the extracellular domain of Neu with that of FGFR2 contain
