Therapeutic Strategies in Huntington's Disease: From Genetic Defect to Gene Therapy.

ABSTRACT: Despite the identification of an expanded CAG repeat on exon 1 of the huntingtin gene located on chromosome 1 as the genetic defect causing Huntington's disease almost 30 years ago, currently approved therapies provide only limited symptomatic relief and do not influence the age of onset or disease progression rate. Research has identified various intricate pathogenic cascades which lead to neuronal degeneration, but therapies interfering with these mechanisms have been marked by many failures and remain to be validated. Exciting new opportunities are opened by the emerging techniques which target the mutant protein DNA and RNA, allowing for "gene editing". Although some issues relating to "off-target" effects or immune-mediated side effects need to be solved, these strategies, combined wi
