Have we seen a breakthrough in preventing genetic diseases?

The Inquiry

The creation of a landmark gene editing drug used to treat a baby with a rare genetic mutation which could help transform personalized medicine. Blood tests showed baby KJ had sky-high levels of ammonia, a toxic substance the body usually expels. The root cause was his genes - or more particularly a specific gene mutation. The race was on to try and treat him before his condition took a firm hold. His doctors came up with a radical solution - for the first time ever, they designed and applied a gene-editing drug in record time, specifically for him. Have we seen breakthrough in preventing genetic diseases?
