Deadly gene mutations removed from human embryos in landmark study

Scientists have modified human embryos to remove genetic mutations that cause heart failure in otherwise healthy young people in a landmark demonstration of the controversial procedure.

It is the first time that human embryos have had their genomes edited outside China, where researchers have performed a handful of small studies to see whether the approach could prevent inherited diseases from being passed on from one generation to the next.

While none of the research so far has created babies from modified embryos, a move that would be illegal in many countries, the work represents a milestone in scientists’ efforts to master the technique and brings the prospect of human clinical trials one step closer.

The work focused on an inherited form of heart disease, but scientists believe the same approach could work for other conditions caused by single gene mutations, such as cystic fibrosis and certain kinds of breast cancer.
