Scientists say the first baby has been born from a controversial new technique that combines DNA from three people — the mother, the father and an egg donor.

The goal was to prevent the child from inheriting a fatal genetic disease from his mother, who had previously lost two children to the illness.

…

Henry Greely, who directs the Center for Law and the Biosciences at Stanford University, said Tuesday he sees nothing wrong with using the technique if it is safe and is aimed at diseases clearly caused by faulty mitochondrial DNA.

But he called the research leading to the newly reported birth “unethical, unwise, immoral.” He said the approach “hasn’t been sufficiently proven safe enough to try to use to make a baby.”
