A new CRISPR gene-editing technique prevented a genetic liver disease known to be driven by hundreds of different mutations and improved clinical symptoms in mice, Penn Medicine researchers reported in new proof-of-concept study published online in Science Advances. The findings suggest a promising CRISPR tool that could potentially treat patients with a rare metabolic urea-cycle disorder caused by a deficiency the enzyme, ornithine transcarbamylase (OTC), as well as other hereditary diseases triggered by different mutations on the same gene.
