I find all the CRISPR news really fascinating. I guess scientists were recently able to edit someone’s DNA without removing it.
In this new experiment, doctors at the Casey Eye Institute in Portland, Ore., injected (into the eye of a patient who is nearly blind from a condition called Leber congenital amaurosis) microscopic droplets carrying a harmless virus that had been engineered to deliver the instructions to manufacture the CRISPR gene-editing machinery.
Francis Collins, director of the National Institutes of Health, calls the advance “a significant moment.”
“All of us dream that a time might be coming where we could apply this approach for thousands of diseases,” Collins tells NPR. “This is the first time that’s being tried in a human being. And it gives us hope that we could extend that to lots of other diseases — if it works and if it’s safe.”
