In August of 2017 Scientists finally had figured out how to successfully edited genes in human embryos in order to treat serious disease-causing mutation using advanced CRISPER/Cas9. This is a major milestone as it brings scientists closer to the reality of being able to genetically engineer babies in order to re
pair faulty genes. This concept has always been feared due to the lack of success and safety of previous genetic tests, however, this study proves that scientists can now successfully edit genes.“We’ve always said in the past gene editing shouldn’t be done, mostly because it couldn’t be done safely,” said Richard Hynes, a cancer researcher at the MassachusettsInstitute of Technology who co-led the committee. “That’s still true, but now it looks like it’s going to be done safely soon,” he said, adding that the research is “a big breakthrough.” Genetic testing has also been regarded as unethical due to the possibility of eugenics, in which wealthy families would pay to have their embryos adjusted to get enhanced cosmetic traits such as height and muscle mass. “What our report said was, once the technical hurdles are cleared, then there will be societal issues that have to be considered and discussions that are going to have to happen. Now’s the time.” This successful study has come out only months after a national scientific committee recommended new guidelines for modifying embryos in which they strongly urge gene editing be used solely for severe hereditary medical conditions.
