Three Parents. One Baby.

Leigh Syndrome is a fatal disorder that affects the developing nervous system in foetuses. This, and other diseases with their origin in the genome often mean a short and difficult life for babies born with the genes that cause them. But remarkable advances in the science of genetic medicine have presented a solution never seen before. By incorporating the healthy DNA from a donor – who becomes a third genetic parent – this controversial technique allows parents carrying rare genetic mutations to have healthy babies and remove undesired genes. The technique has already resulted in the birth of a healthy baby boy. Carte Blanche meets the doctor who has pioneered this remarkable medical breakthrough.
