Analysis of trinucleotide repetitive sequences for Korean patients with spinocerebellar ataxia types 8, 12, and 17

autosomal recessive, X-linked, and mitochondrial SCAs according to the mode of inheritance. Among these, autosomal dominant SCAs is the most common subtype, and more than 30 autosomal dominant SCAs have been identified to date. The causative genes associated with SCAs include SCA1 (ATXN1), SCA2 (ATXN2), SCA3 (ATXN3), SCA5 (SPTBN), SCA6 (CACNA1A), SCA7 (ATXN7), SCA8 Analysis of trinucleotide repetitive sequences for Korean patients with spinocerebellar ataxia types 8, 12, and 17
