Summary
Branchio-oculo-facial (BOF) syndrome, a rare disorder, is detailed in a Chinese boy with characteristic features. Investigating the EYA1 gene may clarify its relationship with Branchio-oto-renal (BOR) syndrome.
Area of Science:
- Genetics
- Pediatrics
- Ophthalmology
Background:
- Branchio-oculo-facial (BOF) syndrome is a rare autosomal dominant disorder with fewer than 50 reported cases globally.
- Understanding the genetic basis and phenotypic overlap with similar syndromes is crucial for diagnosis and management.
Observation:
- A 7-year-old Chinese boy presented with classic BOF syndrome features: bilateral branchial cleft cysts, cleft palate, lacrimal duct obstruction, and low-set ears.
- The patient exhibited normal intelligence and growth, highlighting variability in BOF syndrome presentation.
Findings:
- This case represents the first reported instance of BOF syndrome in Taiwan.
- Phenotypic overlap with Branchio-oto-renal (BOR) syndrome includes external ear anomalies, hearing loss, lacrimal duct obstruction, and potential renal abnormalities.
Implications:
- The precise relationship between BOF and BOR syndromes remains unclear, with proposed mechanisms including gene deletion or mutations in the EYA1 gene.
- Detecting EYA1 gene mutations in BOF patients could be pivotal in differentiating these syndromes and advancing research.
