... One of these tricks they can do is to serve as a sort of stop sign for the cell. When the machinery that normally reads DNA arrives at the mutant HD gene, appropriately designed genome editing tools can call them off - telling them not to do their work at that precise gene.

DNA vaccination
DNA vaccination is a technique for protecting an animal against disease by injecting it with genetically engineered DNA so cells directly produce an antigen, resulting in a protective immunological response. Several DNA vaccines have been released for veterinary use, and there has been promising research using the vaccines for viral, bacterial and parasitic diseases, as well as to several tumour types. Although only one DNA vaccine has been approved for human use, DNA vaccines may have a number of potential advantages over conventional vaccines, including the ability to induce a wider range of immune response types.
