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.

Oxford University Press, Diagnosis A diagnosis of CFND may be suspected after a thorough clinical evaluation and characteristic physical findings. Mechanisms and functions of Eph and ephrin signalling. X-linked dominant inheritance works differently depending upon whether the mother left image or father right image is the carrier of a gene that causes a disease or disorder.
Aarskog syndrome is an extremely rare genetic disorder marked by stunted growth that may not become obvious until the child is about three years of age, broad facial abnormalities, musculoskeletal and genital anomalies, and mild intellectual disability. Dissecting the molecular mechanisms in craniofrontonasal syndrome: In the family reported by Kumar et al. Nine cases were familial, and 29 cases were sporadic. One limb may be shorter than the other.
Rare Disease Database
NORD gratefully caniofrontonasal Prof. Treatment of CFND depends upon the specific malformations and their severity in each individual patient, and the timing of diagnosis. Symptoms of the following disorders can be similar to those of craniofrontonasal dysplasia.
However, this is quite difficult as facial involvement may not be obvious at such an early age, especially in cases with mild phenotypic presentation.
Aarskog syndrome is inherited as an X-linked recessive genetic condition. Summary and related texts. Craniofrontonasal dysplasia is a very rare genetic condition. Skull x-rays showed synostosis of the coronal suture, and CT scan showed an enlarged ventricular system without apparent structural malformation.
Retrieved from ” https: Detailed phenotypic analysis in these families showed that females were more severely affected than males; affected males showed hypertelorism as the only sign, and none had coronal synostosis in contrast to the findings in their female relatives.
Very often the condition is not diagnosed in males unless they are a member of a family known to have the condition or the father of a daughter with the condition. Phenotypic expression varies greatly between individuals with CFND.
Related Disorders Symptoms of the following craniiofrontonasal can be similar to those of craniofrontonasal dysplasia. These results supported cellular interference as being the cause of the more severe phenotype in CFNS females.
Females may have a uterus anomaly that may cause an increased incidence of miscarriages. Color blindness red and green, but not blue Ocular albinism craniofrontpnasal Norrie disease Choroideremia Other: The father displayed hypertelorism and a widow’s peak, and had pectus carinatum that had been surgically corrected, whereas the daughter had hypertelorism, bifid nasal tip, widow’s peak, frontal bossing, and a widened metopic suture. The head typically has an unusual craniofrontonasap due to premature closure of the fibrous joints sutures between certain bones in the skull coronal synostosis resulting in facial asymmetry.
In addition, there was bilateral cryptorchidism. Craniofrontonasal dysostosis with deafness and axillary pterygia. The phenotypically normal mother had normal chromosomes.

Haemophilia A Haemophilia B X-linked sideroblastic anemia. It was first recognised as a distinct condition in by Professor Michael Cohen who worked in Canada. The Birth Defects Encyclopedia. Females have a more severe form of the disorder.
Each patient needs to be assessed and treated based on their specific presentation in order to restore the aesthetic and functional balance. A bonus to all MIMmatch users is the option to sign up for updates on new gene-phenotype relationships. One son of an affected female was considered to be affected because of hypertelorism with an inner canthal distance greater than the 97th centile at 9 years of age. Long-term results after 40 years experience with treatment of rare facial clefts: All affected persons had hypertelorism, bifid or broad nose, and highly arched palate.
Plastic and Reconstructive Surgery. Clinical and genetic aspects of craniofrontonasal syndrome: Comparisons may be useful for a differential diagnosis: They concluded that the segregation does not fit autosomal dominant, autosomal recessive, X-linked dominant, or X-linked recessive inheritance.
