Basic and Clinical Application of Adeno-Associated Virus-Mediated Genome Editing.

Traditional gene therapy (gene replacement) has made a breakthrough in treating inherited diseases. Adeno-associated virus (AAV) has emerged as a highly promising vector with innate ability, boosting the development of gene replacement and gene targeting. With the recent advance of engineered nucleases that work efficiently in human cells, AAV mediated-genome editing with nucleases has raised hopes for in situ gene therapy of inherited and non-inherited diseases. Here, the applications of AAV-mediated genome editing are highlighted, and the prospect of AAV and nucleases that will render extension of such success in clinical gene therapy is discussed.
