Insights
This study reports the first Indian family with choreo-acanthocytosis syndrome. Even seemingly healthy members exhibited acanthocytosis, indicating a multisystem disorder affecting cell membranes.
Area of Science:
- Neurogenetics
- Hematology
- Cell Biology
Background:
- Choreo-acanthocytosis syndrome is a rare, inherited neurodegenerative disorder.
- It is characterized by involuntary movements (chorea) and abnormal red blood cell morphology (acanthocytosis).
- Limited data exists on its prevalence and presentation in India.
Observation:
- A family in India with 4 sisters and 3 brothers was investigated.
- The proband presented with a complete form of choreo-acanthocytosis syndrome.
- Two deceased brothers had a history of the disease but no blood examination records.
Findings:
- The proband displayed classic symptoms of choreo-acanthocytosis.
- Apparently healthy family members also showed acanthocytosis in their blood.
- This suggests acanthocytosis is a consistent marker in affected families.
Implications:
- This is the first documented case of choreo-acanthocytosis in India.
- The presence of acanthocytosis in healthy relatives suggests a broader impact on cell membranes.
- This finding highlights choreo-acanthocytosis as a multisystem disorder with potential for subclinical manifestations.
Abstract:
This is the first report from India of a family of 4 sisters and 3 brothers in whom the proband showed a complete form of the choreo-acanthocytosis syndrome, whereas the 2 brothers who had died earlier of this disease had no examination of their blood. The apparently healthy members of this family also showed acanthocytosis, suggesting that this is a multisystem disorder affecting cell membranes.
