First U.S. Patients Treated With CRISPR As Gene-Editing Human Trials Get Underway

CRISPR-CAS9 gene editing technology allows scientists to make highly precise modifications to DNA. The technology is now starting to be used in human trials to treat several diseases in the U.S.

This could be a crucial year for the powerful gene-editing technique CRISPR as researchers start testing it in patients to treat diseases such as cancer, blindness, and sickle cell disease.
