One indication of this disease is a low level of CREB binding proteins. When the mutation that causes this disease is present on a different gene, it can cause spinocerebellar ataxia. One drug approved to treat this disease is tetrabenazine, and the cause of this disease is a creation of a polyglutamine tract, due to an overproduction of CAG repeats. This disease is caused by an autosomal dominant mutation, and it normally appears at the beginning of middle age. For 10 points, name this genetic disease whose symptoms includes involuntary movements known as its namesake chorea.
