Orphanet epidemiological data:

branchio-oculo-facial syndrome:
Inheritance: Autosomal dominant; Prevalence: <1/1000000 (Worldwide); Age of onset: Neonatal


branchiooculofacial syndrome:
Inheritance: autosomal dominant inheritance


Penetrance: bofs has shown almost complete penetrance. careful examination of individuals identified in a family with bofs with a tfap2a pathogenic variant is necessary to reveal subtle findings including premature graying (individuals may have dyed their hair), faint hair on the neck, or heterochromia of the irides...

MalaCards based summary: Branchiooculofacial Syndrome, also known as branchio-oculo-facial syndrome, is related to pulmonic stenosis and microphthalmia, and has symptoms including Array, Array and Array. An important gene associated with Branchiooculofacial Syndrome is TFAP2A (Transcription Factor AP-2 Alpha), and among its related pathways is Transcriptional regulation by the AP-2 (TFAP2) family of transcription factors. Affiliated tissues include skin, eye and thymus, and related mouse phenotype vision/eye.

Disease Ontology:11 An autosomal dominant disease that is characterized by low birth weight and growth retardation, bilateral branchial clefts.

Genetics Home Reference:25 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:48 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

UniProtKB/Swiss-Prot:70 Branchiooculofacial syndrome: A syndrome characterized by growth retardation, bilateral branchial sinus defects with hemangiomatous, scarred skin, cleft lip with or without cleft palate, pseudocleft of the upper lip, nasolacrimal duct obstruction, low set ears with posterior rotation, a malformed, asymmetrical nose with a broad bridge and flattened tip, conductive or sensorineural deafness, ocular and renal anomalies.
