Gene editing in human embryos takes step closer to reality

Successful correction of genetic problems in mice before birth raises hopes of similar treatments for humansGene editing to correct faulty DNA in human embryos has taken a step closer to becoming a reality, with scientists showing it is possible to correct genetic problems in mice before they are born.Researchers used a form of the gene-editing tool Crispr-Cas9 to introduce a mutation into a gene that would otherwise cause lethal liver failure in mice. While the approach has previously been shown to work in mice after birth, the latest study showed it was also possible to make the all-important tweak before they were born.Continue reading...
