چکیده

Craniofrontonasal syndrome (CFNS) is a rare X-linked disorder that shows greater severity in females and is largely attributed to mutations in EFNB1. A 7-year-old boy presented with hypertelorism, broad nasal root, midfacial hypoplasia, mandibular prognathia, ptosis, and scaphocephaly was clinically diagnosed with CFNS. Three-dimensional computed tomographic scans confirmed the isolated sagittal synostosis. His mother also showed clinical features of CFNS, but less severe. Genetic tests uncovered a novel C to T mutation at nucleotide 466 (c.466C>T) in exon 1 of EFNB1 for both. To the best of our knowledge, this is the only reported incident of CFNS in a male child exhibiting isolated sagittal synostosis.

A novel EFNB1 mutation in a patient with craniofrontonasal syndrome and right hallux duplication.

Craniofrontonasal syndrome (CFNS, MIM #304110) is a rare X-linked dominant developmental disorder that shows paradoxically greater severity in affected females than in affected males. Our female patient with frontonasal dysplasia, craniosynostosis and additional malformations was consistent with CFNS. EFNB1, which encodes a member of the ephrin family of transmembrane ligands for Eph receptor t...

Identification and expression analysis of a novel intragenic EFNB1 mutation causing craniofrontonasal syndrome☆

Craniofrontonasal syndrome (CFNS) is an X-linked disorder caused by mutations in the EFNB1 gene and characterized by distinctive craniofacial and digital malformations. In contrast with most X-linked traits, female patients with CFNS display a more severe phenotype than males. In this report, the clinical, molecular and RNA expression analyses of a female subject with CFNS are described. A nove...

Craniofrontonasal syndrome in a male due to chromosomal mosaicism involving EFNB1: further insights into a genetic paradox.

Craniofrontonasal syndrome (CFNS) is an X-linked disorder caused by inactivating mutations in the gene for ephrin-B1 (EFNB1). Paradoxically it shows a more severe phenotype in females than in males. As a result of X inactivation cell populations with and without EFNB1 expression are found in EFNB1+/- females. This is thought to initiate a process termed cellular interference which may be respon...

A Novel De Novo EFNB1 Gene Mutation in a Mexican Patient with Craniofrontonasal Syndrome

Craniofrontonasal syndrome (CNFS) is an X-linked disorder caused by mutations in the EFNB1 gene in which, paradoxically, heterozygous females are more severely affected than hemizygous males. In this paper, the clinical and molecular studies of a female subject with CFNS are described. A novel de novo c.473T>C (p.M158T) mutation in exon 3 of EFNB1 was demonstrated in this patient. The M158 resi...

Genetic Syndromes Associated with Craniosynostosis

Craniosynostosis is defined as the premature fusion of one or more of the cranial sutures. It leads not only to secondary distortion of skull shape but to various complications including neurologic, ophthalmic and respiratory dysfunction. Craniosynostosis is very heterogeneous in terms of its causes, presentation, and management. Both environmental factors and genetic factors are associated wit...
