(BBC) – Precise “chemical surgery” has been performed on human embryos to remove disease in a world first, Chinese researchers have told the BBC. The team at Sun Yat-sen University used a technique called base editing to correct a single error out of the three billion “letters” of our genetic code. They altered lab-made embryos to remove the disease beta-thalassemia. The embryos were not implanted.┬áThe team says the approach may one day treat a range of inherited diseases.
