Craniofrontonasal dysplasia is a very rare X-linked malformation syndrome caused by mutations in the ephrin-B1 gene (EFNB1). Phenotypic expression varies. Disease definition. Craniofrontonasal dysplasia is an X-linked malformation syndrome characterized by facial asymmetry (particularly orbital), body asymmetry.

Craniofrontonasal dysostosis with deafness and axillary pterygia. Sax and Flannery reviewed 8 published pedigrees and added a ninth. Orocraniodigital syndrome is thought to be inherited as an cfaniofrontonasal recessive genetic condition.

Some patients have a complete or partial absence of the corpus craniofrontonasla, the band of nerves that connect the two hemispheres of the brain. All 6 patients had documented coronal craniosynostosis and exhibited severe hypertelorism; other features included agenesis of the corpus callosum, bifid nasal tip, longitudinally split nails, cryptorchidism, and mild learning disability.

One male with 2 affected daughters and no other children was judged to be unaffected or to have at the most ‘microsymptoms. Other search option s Alphabetical list.

There are many other rare craniofacial disorders that are characterized by facial abnormalities similar to those of CFND.

In addition, the mother had also previously undergone therapeutic abortion of a female fetus with congenital diaphragmatic hernia. Molecular genetic testing for mutations in the EFNB1 gene is available to confirm the diagnosis. Check this box if you wish to receive a copy of your message.


Alternative names are Craniofrontonasal Dysplasia and Craniofrontonasal Dysostosis. Aarskog syndrome is inherited as an X-linked recessive genetic condition. Long-term surgical outcome for craniofacial deformities of patients with craniofrontonasal dysplasia with proven EFNB1 mutations. Part 2 e symmetrical median clefts. Clinical Synopsis Toggle Dropdown.

Physical characteristics may play a supportive role in establishing the diagnosis. This is due to the large heterogeneity between patients regarding phenotypic expression. The symptoms of CFND vary greatly in craniofrnotonasal and severity among affected individuals.

Craniofrontonasal dysplasia CFND is a very rcaniofrontonasal inherited disorder characterized by body — especially facial – asymmetry, midline defects, skeletal abnormalities, and dermatological abnormalities. These results supported cellular interference as being the cause of the more severe phenotype in CFNS females.

Skull x-rays showed synostosis of the coronal suture, and CT scan showed an enlarged ventricular system without apparent structural malformation. A family with craniofrontonasal dysplasia, and fragile site 12q13 segregating independently.

Diverse clinical and genetic aspects of craniofrontonasal syndrome. However, some cases are thought to run in families. X-linked dominant inheritance works craniofrononasal depending upon whether the mother left image or father right image is the carrier of a gene that causes a disease or disorder.


In most cases, GCPS is inherited as an autosomal dominant trait. Comparisons may be useful for a differential diagnosis:. In the family reported by Kumar et al.

Hurst and Baraitser confirmed the female preponderance in this condition and noted that all of their patients had thick, wiry hair.

Ears were thick and low set, and the neck was short without webbing. For more information on Sprengel deformity, see the Related Disorders section of this report. Oxford University Press, Together we are strong. The skull tends to be short from dyspoasia to back referred to descriptively as Brachycephaly coronal sutures. Each patient needs to be assessed and treated based on their specific presentation in order to restore the aesthetic and functional balance.

Some of the more prominent characteristics are: In addition to the coronal craniosynostosis and facial changes, syndactyly of fingers and toes and longitudinally grooved nails were present. Johnson suggested that dysplasis disorders may show up only cranifrontonasal heterozygotes as a result of adverse interaction of 2 alleles, neither of which occasions abnormality when homozygous or hemizygous.
