RNA repair: a novel approach to gene therapy.
Treatment of genetic disorders by gene therapy has conventionally been attempted through the transfer of a wild type version of a gene to the cells of a patient harboring defective copies of a disease associated gene. Despite significant advances using this paradigm, several technical hurdles must still be overcome before this 'gene replacement' approach will become useful in the treatment of a variety of genetic maladies. Such limitations have led a number of researchers to begin to investigate alternative strategies to genetic therapy. Repair of mutant genetic instructions represents a fundamentally different approach to genetic therapy that may have significant advantages over gene replacement. Herein, we will discuss recent advances using repair of mutant RNAs as a novel means to correct genetic deficiencies.
