NCIt definition : Human ATXN3 wild-type allele is located in the vicinity of 14q32.12 and is approximately
62 kb in length. This allele, which encodes ataxin-3 protein, is involved in the regulation
of protein homeostasis, gene transcription, cytoskeletal modeling, myogenesis and
degradation of misfolded chaperone substrates. The expansion of (CAG)n trinucleotide
repeats in the gene from the normal 12-44 to 52-86 is associated with spinocerebellar
ataxia 3 (Machado-Joseph disease).;
