Interestingly, there is a 2020 case report of a 62-year-old man with long-standing cerebellar ataxia and cervical dystonia who was found to have a novel mutation in CACNA1A. He had a 40-year history of slowly progressive gait instability and a 15-year history of cervical dystonia; he had begun requiring unilateral support 5 years prior to presentation. The gene discussed is CACNA1A; the disease is aceruloplasminemia.
