Doctors Are Attempting the First Case of Gene Editing Inside the Body of a Living Human

November 15, 2017

(Quartz) – But Madeux’s life might be about to change. He is the first patient to receive an experimental gene therapy as part of a clinical trial. Earlier this week, Sangamo Therapeutics injected Madeux with viruses containing a package of gene-editing material, according to the AP. The hope is that these viruses will enter Madeux’s cells, specifically liver cells, inject the missing gene at the right place in his DNA. Only about 1% of the liver’s cells need to be fixed, and give his liver the ability to produce the enzyme he has been missing all his life.
