<div class="c-text">
<p>Best vitelliform macular degeneration, or Best disease, is an inherited eye condition that typically leads to blindness over the course of a few decades. The disease can be caused by more than two hundred mutations in the <em>BEST1</em> gene.</p><p>The researchers were able to correct the disease in stem cells from patients with <em>BEST1</em> mutations by overwhelming broken copies of the gene with many functional copies of <em>BEST1</em>. This approach worked for most, but not all, of the <em>BEST1</em> mutations that they tested. As an alternative approach for mutations that did not respond to this gene augmentation method, the team used CRISPR-Cas9 gene editing to target and correct the mutations.</p>
