DNA editing in human embryos reveals role of fertility 'master gene'

In a first for the UK, genome editing has been used to understand embryo development, and could help uncover the causes of recurrent miscarriages

Scientists in Britain have revealed the role of a fertility "master gene" in one of the world's first demonstrations of DNA editing in human embryos.

The study, which marks a first for the UK, could help uncover the cause of recurrent miscarriages and lead to more effective fertility treatments. It also raises ethical questions about the prospect of controversial gene editing techniques being used clinically to correct defects in, or even enhance, human embryos in the future.
