Eye movement abnormalities in spinocerebellar ataxia type 17 (SCA 17)

Spinocerebellar ataxia type 17 (SCA17) is associated with an expansion of CAG/CAA trinucleotide repeats in the gene encoding TATA-binding protein (TBP). The aim of this study was to characterize eye movements in SCA17 and to localize oculomotor deficits.
