UK Govt Backs Three-person IVF

The UK looks set to become the first country to allow the creation of babies using DNA from three people, after the government backed the IVF technique.

It will produce draft regulations later this year and the procedure could be offered within two years.

Experts say three-person IVF could eliminate debilitating and potentially fatal mitochondrial diseases that are passed on from mother to child, reports the BBC.

Opponents say it is unethical and could set the UK on a "slippery slope".

They also argue that affected couples could adopt or use egg donors instead.

Mitochondria are the tiny, biological "power stations" that give the body energy. They are passed from a mother, through the egg, to her child.

Defective mitochondria affect one in every 6,500 babies. It can leave them starved of energy, resulting in muscle weakness, blindness, heart failure and death in the most extreme cases.

Research suggests that using mitochondria from a donor egg can prevent the diseases.

It is envisaged that up to 10 couples a year would benefit from the treatment.

However, it would result in babies having DNA from two parents and a tiny amount from a third donor as the mitochondria themselves have their own DNA.

Earlier this year, a public consultation by the Human Fertilisation and Embryology Authority (HFEA) concluded there was "general support" for the idea and that there was no evidence that the advanced form of IVF was unsafe.

The chief medical officer for England, Prof Dame Sally Davies, said: "Scientists have developed ground-breaking new procedures which could stop these disease being passed on, bringing hope to many families seeking to prevent their future children inheriting them.

"It's only right that we look to introduce this life-saving treatment as soon as we can."

She said there were "clearly some sensitive issues here" but said she was "personally very comfortable" with altering mitochondria.

Scientists have devised two techniques that allow them to take the genetic information from the mother and place it into the egg of a donor with healthy mitochondria.
