British MPs (国会议员) have voted in favour of the creation of babies with DNA from two women and one man, in a historic move. The UK is now set to become the first country to introduce laws to allow the creation of babies from three people. In a free vote in the Commons, 382 MPs were in favour and 128 against the technique that stops genetic diseases being passed from mother to child. During the debate, ministers said the technique was “light at the end of a dark tunnel” for families.

A further vote is required in the House of Lords. If everything goes ahead then the first such baby could be born next year. Supporters said it was “good news for progressive medicine” but critics say they will continue to fight against the technique that they say raises too many ethical (伦理的) and safety concerns. Estimates suggest 150 three-person babies could be born each year.

Prime Minister David Cameron said: “We're not playing god here; we're just making sure that two parents who want a healthy baby can have one.” The method, which was developed in Newcastle, should help women like Sharon Bernadi, from Sunderland, who lost all seven of her children to mitochondrial (线粒体的) disease. Ms Bernadi said she was “overwhelmed” by the decision.

Mitochondria are the tiny compartments (隔间) inside nearly every cell of the body that transform food into useable energy. They have their own DNA, which does not affect characteristics such as appearance. Defective mitochondria are passed down only from the mother. They can lead to brain damage, muscle wasting, heart failure and blindness. The technique uses a modified version to combine the DNA of the two parents with the healthy mitochondria of a donor woman. It results in babies with 0.1% of their DNA from the second woman and is a permanent change that would be passed down through the generations.
