Pre-birth genetic modification

First pre-birth genetic modification could be approved soon in the UK to correct faulty mitochondria
Dr Mitalipov, who headed the research, explained: “Using this process, we have shown that mutated DNA from the mitochondria can be replaced with healthy copies in human cells.” Indeed, by using 106 human eggs donated by healthy volunteers, the team demonstrated that although the ST-IVF grants chances of successful in vitro fertilization lower than the standard IVF (50% versus 75%), the viable embryos undergo normal development. More importantly, the rate of success is not impaired by use of cryo-preserved human eggs, a condition that will be critical for clinical applications of ST.
