A group of dominantly inherited, predominately late-onset, cerebellar ataxias which have been divided into multiple subtypes based on clinical features and genetic mapping. Progressive ataxia is a central feature of these conditions, and in certain subtypes POLYNEUROPATHY; DYSARTHRIA; visual loss; and other disorders may develop.

Ataxin-3. : Autophagy and neurodegeneration / David Rubinsztein
A deubiquitinating enzyme of the ATAXINS family. It functions in protein homeostasis, GENETIC TRANSCRIPTION; CYTOSKELETON regulation, and MYOGENESIS. CAG TRINUCLEOTIDE REPEAT EXPANSION in the Ataxin-3 gene coding region is associated with spinocerebellar ataxia-3 (MACHADO-JOSEPH DISEASE)
