Britain Becomes First Country to Allow So-Called "Three-Person Babies"

The Guardian: Britain's House of Lords approves conception of three person babies, by Hannah Devlin:

Britain has become the first country in the world to permit the use of “three-person IVF” to prevent incurable genetic diseases.

The House of Lords voted by 280 votes to 48 on Tuesday evening to approve changes to the law allowing fertility clinics to carry out mitochondrial donation. Babies conceived through this IVF technique would have biological material from three different people – a mother, father and a female donor. . . . 

Technically the baby would have three biological parents, with 99.8% of genetic material coming from the mother and father and 0.2% coming from the mitochondrial donor. . . .

PBS: Why the term 'three-person baby' makes doctors wince, by Rebecca Johnson: 

MELAS is one of about 200 known mitochondrial diseases, a subject that has featured prominently in the news since the British Parliament’s House of Commons on Feb. 3 approved further testing and research on mitochondrial replacement IVF. The procedure has beencommonly referred to in news stories as “three-person babies” or “three-parent babies.”

But it’s a term that makes doctors wince. . . .
