Gene editing now poses such low risks that it can be used in human embryos, according to an analysis by Kevin Smith, a bioethicist at the University of Abertai in Scotland, published last week in the journal Bioethics.
Proponents like Smith want to change the genetic makeup of embryos to prevent the transmission of gene-related diseases.
However, the practice is extremely controversial for fear that it may be used to create "designer babies" whose genes have been edited for non-therapeutic purposes.
But Smith says creating them is ethically justified and would offer hope for parents at risk of transmitting a serious genetic disease to their offspring, according to a statement.
