Summary
Pallister-Killian syndrome was diagnosed in a baby investigated for hearing loss. A skin biopsy proved crucial for identifying this rare genetic disorder.
Area of Science:
- Genetics
- Pediatrics
- Medical Diagnostics
Background:
- Pallister-Killian syndrome (PKS) is a rare genetic disorder characterized by mosaicism for an extra isochromosome 12p.
- Early diagnosis is critical for appropriate management and intervention.
Observation:
- A nine-month-old infant presented with concerns for hearing loss.
- Diagnostic investigations, including a skin biopsy, were performed.
Findings:
- The skin biopsy revealed the genetic abnormality consistent with Pallister-Killian syndrome.
- Hearing loss was a presenting concern that led to the PKS diagnosis.
Implications:
- This case highlights the importance of considering PKS in infants with developmental concerns.
- Skin biopsy is a valuable diagnostic tool for identifying PKS, even when other symptoms are not immediately apparent.
- Timely diagnosis facilitates early intervention and improves patient outcomes.
