MalaCards based summary: Branchiooculofacial Syndrome, also known as branchio-oculo-facial syndrome, is related to burn-mckeown syndrome and polydactyly, and has symptoms including low posterior hairline, low-set, posteriorly rotated ears and overfolded helix. An important gene associated with Branchiooculofacial Syndrome is TFAP2A (transcription factor AP-2 alpha (activating enhancer binding protein 2 alpha)). Affiliated tissues include skin, eye and kidney, and related mouse phenotypes are hearing/vestibular/ear and mortality/aging.

Disease Ontology:8 An autosomal dominant disease that is characterized by low birth weight and growth retardation, bilateral branchial clefts.

Genetics Home Reference:21 Branchio-oculo-facial syndrome is a condition that affects development before birth, particularly of structures in the face and neck. Its characteristic features include skin anomalies on the neck, malformations of the eyes and ears, and distinctive facial features.

NIH Rare Diseases:42 Branchiooculofacial syndrome (bofs) is a very rare genetic disorder that is apparent at birth. only about 50 cases of bofs had been reported in the medical literature. like its name implies, bofs is characterized by skin defects, eye abnormalities, and distinctive facial features. among the reported cases thus far, the symptoms may vary from mild to severe. bofs is caused by mutations in the tfap2a gene and inherited as an autosomal dominant trait. last updated: 6/23/2011
