Uproar over gene editing

Country

China

A Chinese scientist’s reported use of the Crispr gene editing tool to alter a gene in two  embryos which were implanted into a mother’s womb has created an uproar in the scientific community. The edit was performed when the embryos were just a day old and involved alterations to the CCR5 gene in order to prevent the offspring from contracting HIV. They were reported on YouTube videos, rather in a scientific journal, after twin girls bearing the DNA changes were born.
