Huntington's disease or chorea is a neurogenerative and hereditary pathology. This disease is inherited in an autosomal dominant manner, so only one copy of the altered gene is required for its development. Huntington's chorea is caused by a mutation in the HTT gene, a gene located on the short arm of chromosome 4.
The disease is named after the physician who discovered it, Dr. George Huntington. The most characteristic clinical manifestation of people with Huntington's disease is rapid involuntary movements with no apparent cause. In addition, this disease causes progressive degeneration of neurons in several areas of the brain.
