New gene therapy could cure a deadly disease that stops the heart from beating

Scientists have successfully tweaked the DNA in human heart cells to correct mutations that cause a deadly disease. If the gene-editing technique is proven safe, it could permanently cure children with a genetic disorder that leaves them wheelchair-bound by their early teens.
The genetic disease targeted in this study is called Duchenne muscular dystrophy (DMD), a disorder that affects about one in 5,000 males and causes the progressive wasting away of skeletal and heart muscles. Researchers to
