PNA-based gene editing technique can advance gene discovery In an article published in the April 8 issue of Nature, the National Institutes of Health's Somatic Cell Gene Editing Consortium provided a detailed update on the progress of their nationwide effort to develop safer and more effective methods to edit the genomes of disease-relevant somatic cells and reduce the burden of disease caused by genetic changes. Gene editing allows scientists to modify sections of an organism's DNA and is considered a promising treatment for a number of genetic diseases. There have been numerous advances in the laboratory over the last few decades, but there are still many challenges to overcome before gene editing can be widely used in the patient population.
