This paper reports a new type of syndromic craniosynostosis that was diagnosed by DNA analysis of the patient’s fibroblast growth factor receptor (FGFR) genes. At birth, a male infant had ocular proptosis, a pseudotail, and obstructed respiration. He developed craniosynostosis, craniofacial dysmorphism, hydrocephalus, and bilateral contracture of his elbow joints. His treatment included fronto-orbital advancements and a ventriculoperitoneal shunt. Genetic analysis revealed that he was heterozygous for a missense mutation in exon 9 of the FGFR2 gene that resulted in an amino acid substitution of cysteine for serine at residue 351 (Ser351Cys). Seven cases with this mutation had previously been reported. All had severe craniosynostosis with midface hypoplasia, elbow joint contracture, developmental retardation, and early death.
