CRISPR/Cas9 gene-editing: Research technologies, clinical applications and ethical considerations

Gene therapy carries the potential to treat more than 10,000 human monogenic diseases and benefit an even greater number of complex polygenic conditions. The repurposing of CRISPR/Cas9, an ancient bacterial immune defense system, into a gene-editing technology has armed researchers with a revolutionary tool for gene therapy. However, as the breadth of research and clinical applications of this technology continues to expand, outstanding...
