Abstract
|
|
|
|
Spinocerebellar ataxia type-2 (SCA2) is an autosomal dominant cerebellar ataxia that occurs due to expanded CAG trinucleotide repeats in the ATXN2 gene. Clinical features of parkinsonism in SCA2 vary from phenotypes of levodopa-responsive parkinsonism to multiple system atrophy. We described a patient with SCA2 presenting typical clinical manifestations of multiple system atrophy-c type with levodopa responsive parkinsonism whose dopamine transporter (DAT) image showed atypically reduced DAT uptake in in the striatum.
