UK doctors birthed healthy babies using three-person DNA

Eight healthy babies have been born in the UK using a novel in-vitro fertilization (IVF) technique involving DNA from three people, marking a medical first. This procedure aims to prevent the transmission of rare genetic diseases. The new IVF method transfers genetic material from the mother's egg or embryo into a donor egg with healthy mitochondria, avoiding harmful mutations. The resulting embryos have DNA from the mother, father, and the donor. This breakthrough, requiring legislative changes, offers hope for couples at risk of passing on mitochondrial diseases. While one baby showed slightly elevated mitochondrial levels, the overall results are promising.
