title: Spinocerebellar ataxia type 2 presenting as familial levodopa-responsive parkinsonism.
abstract: A genetic analysis identified 2 patients, approximately one-tenth of our patients with familial parkinsonism, who had expanded trinucleotide repeats in SCA2 genes. The reduction of 18F-dopa distribution in both the putamen and caudate nuclei confirmed that the nigrostriatal dopaminergic system was involved in parkinsonian patients with SCA2 mutation.
