Hajdu Cheney Syndrome

Area of Science:

• Genetics
• Rare Diseases
• Bone Metabolism

Background:

• Hajdu-Cheney Syndrome (HCS) is a rare autosomal dominant disorder.
• Characterized by progressive focal bone destruction, HCS onset is from birth but diagnosis is often delayed.
• Sporadic cases have also been reported, adding complexity to its genetic profile.

Observation:

• A 26-year-old male presented with severe periodontitis and premature tooth loss.
• The patient exhibited characteristic craniofacial dysmorphism, digit abnormalities, and dental anomalies.
• These features prompted further investigation into a potential underlying systemic disorder.

Findings:

• The case confirmed Hajdu-Cheney Syndrome as the underlying diagnosis.
• The presentation underscores the variability in HCS manifestation and delayed diagnosis.
• Severe periodontitis and premature tooth loss can be key indicators in adult patients.

Implications:

• Early recognition of craniofacial and dental abnormalities is crucial for identifying HCS.
• Multidisciplinary specialist evaluation can lead to earlier diagnosis and management.
• Timely diagnosis can prevent advanced disease progression and improve patient outcomes.
