Chorea-acanthocytosis (ChAc) is a rare neurodegenerative disorder most commonly referred to by its clinical name or the abbreviation ChAc. While it is sometimes historically labeled as a form of "neuroacanthocytosis," it is now recognized as a distinct clinical entity characterized by chorea and abnormally shaped red blood cells known as acanthocytes. What are the common synonyms and historical names for Chorea-acanthocytosis? In medical literature, Chorea-acanthocytosis is frequently categorized under the broader umbrella of neuroacanthocytosis syndromes.

Chorea-acanthocytosis (ChAc) is a rare neurodegenerative disorder most commonly referred to by its clinical name or the abbreviation ChAc. While it is sometimes historically labeled as a form of "neuroacanthocytosis," it is now recognized as a distinct clinical entity characterized by chorea and abnormally shaped red blood cells known as acanthocytes.
What are the common synonyms and historical names for Chorea-acanthocytosis?
In medical literature, Chorea-acanthocytosis is frequently categorized under the broader umbrella of neuroacanthocytosis syndromes. Older texts may use the term "Levine-Critchley syndrome," named after the researchers who first described the association between chorea and acanthocytosis in the 1960s. Because Chorea-acanthocytosis involves complex neurological and hematological features, you may occasionally see it referred to as "choreoacanthocytosis" (a minor spelling variation) or by its OMIM identifier, #200150.
Why does Chorea-acanthocytosis have multiple names?
The nomenclature for Chorea-acanthocytosis has evolved as genetic research has advanced. Initially, clinicians grouped various conditions featuring movement disorders and red blood cell abnormalities together under the term "neuroacanthocytosis." As the specific genetic mutation in the VPS13A gene was identified, Chorea-acanthocytosis was reclassified as a distinct autosomal recessive disorder. This shift from descriptive, symptom-based naming to genotype-based classification explains why older medical records may reflect broader, less specific terminology.
What is the current preferred medical terminology for Chorea-acanthocytosis?
Medical professionals and major health organizations now standardize the name to Chorea-acanthocytosis (often abbreviated as ChAc) to ensure clarity in clinical settings and research. This term is preferred because it explicitly describes the two hallmark features of the condition:
- Chorea: Involuntary, jerky, dance-like movements.
- Acanthocytosis: The presence of spiky-appearing red blood cells (acanthocytes) in a peripheral blood smear.
Next steps
- Consult a neurologist specializing in movement disorders to confirm a diagnosis through genetic testing for the VPS13A gene.
- Connect with the DiseaseMaps.org community, where 6 individuals living with Chorea-acanthocytosis share their experiences and navigation strategies.
- Request that your medical records use the official term Chorea-acanthocytosis (ICD-10: G10) to avoid confusion during specialist referrals.
