The technique, known as 'mitochondrial donation', is said by some experts to help prevent deadly genetic diseases. The process works by removing defective mitochondria – which are passed only from mother to child – and replacing them with the healthy mitochondria of another woman. The nuclear DNA, which contains 99.9% of genetic material from the mother and father, remains unchanged, but as mitochondria have a tiny amount of their own DNA, any child as a result of the treatment would have genetic information from three people.
While experts have said the process could prevent the transmission of serious mitochondrial disease in a foetus, others have questioned the safety, not to mention the ethics, of such a method.
If the change to the Human Fertilisation and Embryology Act (1990) is approved, it would mean the UK would become the first country to approve the treatment. It is thought the process could benefit up to 150 couples in the UK each year; and if a 'yes' vote is made in the House of Commons, it is thought the first three-person baby could be born as early as next year.
