First child born with DNA from three parents

A five-month-old baby was the first to be born using a new technique that allows parents with severe genetic mutations to have healthy children.

In this case, the mother carries genes for Leigh syndrome, which is a fatal disorder that affects the development of the nervous system. Around a quarter of the mother’s mitochondria have the disease-causing mutation in them, yet the mother is healthy.
