Transcriptional dysregulation is now thought to be a common feature of polyglutamine disorders, including the spinocerebellar ataxias (SCAs). However, the precise causes of transcriptional alterations and how they relate to the observed phenotype remain elusive. Transcriptional impairment differs in different diseases, possibly reflecting the specific functions of the disease-causing proteins. The SCA7 gene product, ataxin-7, is a subunit of a transcriptional coactivator complex (called STAGA… CONTINUE READING
