In Vitro Fertilization with 3 Parents Could Prevent Inherited Disease

In Vitro Fertilization with 3 Parents Could Prevent Inherited Disease: "In Vitro fertilization using DNA from three parents could be newest way to prevent inherited disease.

Britain is considering whether to approve a new fertility treatment that swaps DNA between two fertilized human eggs. British scientists from Newcastle University say they have mastered the technique with cloning technology.

The process involves removing malfunctioning mitochondrial DNA that could lead to a range of conditions. The malfunctioning cells are then replaced with healthy ones from a second 'mother' who donated an egg.

'As doctors we have a duty to treat disease and where possible to prevent disease. With diseases for which there are no treatments the imperative to develop new treatments is even greater,' said Alison Murdoch, the head of Newcastle's department of reproductive medicine."
