Question: What is (are) Chorea-acanthocytosis ?
Answer: Chorea-acanthocytosis is one of a group of conditions called the neuroacanthocytoses that involve neurological problems and abnormal red blood cells. The condition is characterized by involuntary jerking movements (chorea), abnormal star-shaped red blood cells (acanthocytosis), and involuntary tensing of various muscles (dystonia), such as those in the limbs, face, mouth, tongue, and throat. Chorea-acanthocytosis is caused by mutations in the VPS13A gene and is inherited in an autosomal recessive manner. There are currently no treatments to prevent or slow the progression of chorea-acanthocytosis; treatment is symptomatic and supportive.
