British scientists create babies with three people's DNA

Eight healthy babies have been born in Britain using a novel technique involving DNA from three people, designed to prevent the transmission of mitochondrial diseases. This marks a significant advancement in reproductive medicine. The technique involves transferring genetic material from a mother's egg into a donor egg with healthy mitochondria, effectively replacing the mother's potentially disease-causing mitochondrial DNA. This process has been used on 22 patients, resulting in eight healthy births. The procedure, approved in the UK in 2016, allows couples to avoid passing on rare genetic diseases. While the technique is not permitted in the U.S., it offers hope for families affected by mitochondrial diseases, which can cause severe health issues.
