Expanding the Toolbox and Targets for Gene Editing

Genome editing holds great promise for treating a range of human genetic diseases. While emerging clustered regularly interspaced short-palindromic repeats (CRISPR) technologies allow editing of the nuclear genome, it is still not possible to precisely manipulate mitochondrial DNA (mtDNA). Here, we summarize past developments and recent advances in nuclear and mitochondrial genome editing. Genome editing holds great promise for treating a range of human genetic diseases.
