British women could soon become pregnant with a baby containing DNA from three people, as experts approve a breakthrough new treatment for the UK.
The process is called mitochondrial replacement therapy (MRT), and involves replacing DNA of a foetus with some from the mother, father, and a female egg donor.
Women are already queueing up for the procedure, according to scientists from the University of Newcastle, who lead the research.
Up to 25 women a year could undergo the treatment on the NHS.
The world’s first “three-parent” child was born in New York in April, although the insemination had to take place in Mexico, because it was not approved in the US at the time.
