This article describes ataxin-1, the protein mutated in the autosomal dominant cerebellar disorder, spinocerebellar ataxia type 1 (SCA1). The specific mutation in SCA1 is a CAG trinucleotide repeat expansion within the coding region of the gene. Thus, SCA1 belongs to the growing family of polyglutamine diseases, all of which affect the nervous system.
