NCIt definition : Human ATXN7 wild-type allele is located in the vicinity of 3p14.1 and is approximately
140 kb in length. This allele, which encodes ataxin-7 protein, plays a role in the
positive regulation of gene transcription through histone acetylation and chromatin
remodeling. The expansion of (CAG)n trinucleotide repeats in the gene from the normal
7-17 to 38-130 is associated with spinocerebellar ataxia 7.;
