Abstract

Spinocerebellar ataxia type 8 (SCA8), originally described in a family characterized by pure cerebellar ataxia, is caused by the expansion of combined CTA/CTG repeats on chromosome 13q21. We experienced a 26-year-old man who presented with a 10-years history of slowly progressive gait ataxia, dysarthria and blepharospasm. We performed genetic studies for SCA1, 2, 3, 6, 7 and 8, and detected CTA/CTG repeat expansion in the SCA8 gene. We now report the first Korean familial case of SCA8 confirmed by genetic study.
