[Review] Therapies targeting DNA and RNA in Huntington's disease

No disease-slowing treatment exists for Huntington's disease, but its monogenic inheritance makes it an appealing candidate for the development of therapies targeting processes close to its genetic cause. Huntington's disease is caused by CAG repeat expansions in the HTT gene, which encodes the huntingtin protein; development of therapies to target HTT transcription and the translation of its mRNA is therefore an area of intense investigation. Huntingtin-lowering strategies include antisense oligonucleotides and RNA interference targeting mRNA, and zinc finger transcriptional repressors and CRISPR-Cas9 methods aiming to reduce transcription by targeting DNA.
