MeSH definition : A family of predominantly nuclear proteins that regulate gene transcription and protein
degradation. The expansion of CAG trinucleotide repeats in genes that encode Ataxins
is associated with SPINOCEREBELLAR ATAXIAS (SCA). In SCA patients, the number of CAG
repeats correlates with the severity of disease and inversely correlates with the
age of disease onset.;
