Wonder what impact that could eventually have on people with Sickle Cell or Beta thalassemia (or the rare case that hits the genetic jackpot and has both).
I don't follow medical tech religiously but read the original article and thought it relevant (I have a friend that actually has both conditions and the treatment for it is brutal).
I think gene therapy is going to solve that well before an approach like this. Those two are some of the lower hanging fruit to go after (well defined, clear mutation in a single gene, etc) and theres a bunch of therapies already in the pipeline to cure them.
