In A 1st, Doctors In U.S. Use CRISPR Tool To Treat Patient With Genetic Disorder

For the first time, doctors in the U.S. have used the powerful gene-editing technique CRISPR to try to treat a patient with a genetic disorder.

"It is just amazing how far things have come," says Victoria Gray, 34, of Forest, Miss. "It is wonderful," she told NPR in an exclusive interview after undergoing the landmark treatment for sickle cell disease.

Gray is the first patient ever to be publicly identified as being involved in a study testing the use of CRISPR for a genetic disease.
