A CRISPR Future New Form of Eugenics?

Story at-a-glance -

  • Using CRISPR, researchers successfully altered DNA in human embryos in a way that would eliminate or correct the genes causing certain inherited diseases
  • If the embryos were implanted into a womb and allowed to grow, the process, which is known as germline engineering, would result in the first genetically modified children — and any engineered changes would be passed on to their own children
  • In Iceland, Down syndrome births are becoming increasingly rare as women choose to have prenatal testing for chromosome abnormalities, and nearly 100 percent terminate pregnancies with a positive result
  • As CRISPR moves ahead, access to accurate and neutral data will be essential and difficult questions relating to eugenics must be asked

Progress is being made in tackling genetic diseases such as sickle-cell anemia and certain forms of blindness and muscular dystrophy.
