Powerful Gene Editing Approach Offers the Promise of Correcting a Range of Rare Diseases
CRISPR is a powerful editing tool, but it works best as a way to knock out genes rather than correct them. New approaches to gene editing, though, are providing the promise of more effective tools for addressing the underlying drivers of monogenic diseases. A recent study in Nature of an approach known as base editing in a mouse model of the ultra-rare genetic condition progeria, a disease that causes premature aging, demonstrated the powerful potential of the approach. While CRISPR has been likened to scissors, base editing has been compared to the find-and-replace function of a word processor. We spoke to study leader David Liu, director of the Merkin Institute for Transformative Technologies at the Broad Institute, about base editing, how it works, and why it may offer the potential to treat a wide range of rare diseases. This episode is part of an occasional series on innovations in gene editing and gene therapy.
