Britain considers allowing 3-parent IVF technique

Britain is considering whether to approve a fertility treatment designed to prevent some incurable inherited diseases under which babies would be conceived from three biological parents. The method, developed by scientists at Newcastle University, swaps DNA between two fertilized human eggs. It involves intervening in the fertilisation process to remove malfunctioning mitochondrial DNA, which can lead to a range of conditions including fatal heart problems, liver failure, brain disorders, blindness and muscular weakness.
