craniosynostoses/arginine

Identical proline-->arginine gain-of-function mutations in fibroblast growth factor receptor (FGFR) 1 (Pro252Arg), FGFR2 (Pro253Arg) and FGFR3 (Pro250Arg), result in type I Pfeiffer, Apert and Muenke craniosynostosis syndromes, respectively. Here, we characterize the effects of proline-->arginine

A recurrent point mutation in the fibroblast growth factor receptor 3 (FGFR3) gene that converts proline 250 into arginine is commonly associated with coronal craniosynostosis and has allowed definition of a new syndrome on a molecular basis. Sixty-two patients with sporadic or familial forms of

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

Recently, the substitution of proline 250 by arginine in the fibroblast growth factor receptor 3 (FGFR3) gene, has been identified in patients with craniosynostosis and defines a new syndrome on a molecular basis. We report a 1-year-1-month-old female with bilateral coronal craniosynostosis who had

The causative relationship between several of the syndromic forms of craniosynostosis and mutations in the fibroblast growth factor receptor (FGFR) loci is now well established. However, within the group of patients with craniosynostosis, there are several families and sporadic cases whose clinical

Premature closure of the sutures that connect the cranial bones during development of the mammalian skull results in a phenotype called craniosynostosis. Recently, several craniosynostosis patients with missense mutations within the gene encoding the interleukin-11 receptor (IL-11R) have been

Jackson-Weiss syndrome is a rare skeletal disorder characterized by craniosynostosis associated with foot malformations. This condition is inherited as an autosomal dominant trait with complete penetrance and wide phenotypic heterogeneity. Mutations in the fibroblast growth factor receptor 2 (FGFR2)

Pfeiffer syndrome is a classic form of craniosynostosis that is caused by a proline-->arginine substitution at amino acid 252 (Pro252Arg) in fibroblast growth factor receptor 1 (FGFR1). Here we show that mice carrying a Pro250Arg mutation in Fgfr1, which is orthologous to the Pfeiffer syndrome

BACKGROUND Muenke syndrome is a fibroblast growth factor receptor 3 (FGFR-3)-associated coronal craniosynostosis syndrome, which was first described in 1997. METHODS We report an infant girl who was born to a 29-year-old primapara at 38 weeks' gestation. When evaluated at 3 days old, physical

OBJECTIVE A recurrent point mutation in the fibroblast growth factor receptor 3 gene that converts proline 250 into arginine has been reported recently in cases of apparently nonsyndromic coronal craniosynostosis. The goal of the present study was to examine the phenotype of patients in whom this

Pfeiffer syndrome (PS) is an autosomal dominant skeletal disorder which affects the bones of the skull, hands and feet. Previously, we have mapped PS in a subset of families to chromosome 8cen by linkage analysis and demonstrated a common mutation in the fibroblast growth factor receptor-1 (FGFR1)

The bHLH transcription factor TWIST1 plays a key role in the embryonic development and in tumorigenesis. Some loss-of-function mutations of the TWIST1 gene have been shown to cause an autosomal dominant craniosynostosis, known as the Saethre-Chotzen syndrome (SCS). Although the functional impacts of

Pfeiffer syndrome (PS) is one of the classic autosomal dominant craniosynostosis syndromes with craniofacial anomalies and characteristic broad thumbs and big toes. We have previously mapped one of the genes for PS to the centromeric region of chromosome 8 by linkage analysis. Here we present
