(*)
This disease is caused by the same mutation that, on a different gene, causes spinocerebellar ataxia. The protein associated with this disease helps mediate endocytosis by interacting with clathrin-binding proteins. A high-penetrance, early-onset form of this disease is called its akinetic rigid or (*) Westphal type. Excess glutamine residues called a polyQ sequence result from a series of CAG repeats that leads to buildup of this autosomal dominant disease's namesake misfolded protein. For 10 points, name this disease whose symptom of uncontrollable, jerky movements led it to be dubbed its namesake's "chorea."
