Patients suffering from SCA3 carry an ATXN3 allele with 60–82 CAG repeats,whereas healthy individuals present a non-pathogenic number of repeats, usually between 13and 41 CAGs. The neurological symptoms that become evident in the third or fourth decadeof life include ataxia, dystonia, muscle weakness, spasticity and ocular symptoms. SCA3belongs to the group of polyglutamine diseases caused by the expansion of CAG repeats inthe coding sequence of the respective genes. The polyglutamine disease family comprisesHuntington’s disease (HD), spinal and bulbar muscular atrophy (SBMA), dentatorubralpallidoluysian atrophy (DRPLA) and six spinocerebellar ataxias type 1, 2, 3, 6, 7 and 17.They share many similarities, including a common mutation type, selective neuronalvulnerability and misfolding and aggregation of polyglutamine protein. All polyglutaminediseases are currently incurable}, type={Text}, URL={http://www.rcin.org.pl/Content/208771/PDF/POZN271_245706_doktorat-switonski.pdf}, }
