The kids are all right: Children with 3-way DNA are healthy

One of the emerging therapies in advanced reproductive techniques involves combining the parts of a healthy egg donor to rejuvenate or correct deficiencies in a woman’s own egg. When a sperm is then added, the resulting person can actually contain the DNA of three people rather than two. Although this technology is currently not available for use in the USA–the first babies have been born in England through this technique. Interestingly, there were 17 babies born in the USA using this technique more than a decade and a half ago. This procedure was then banned due to potential health concerns in the children that resulted. We now have a follow up report on these original children who are now teenagers. Most importantly, this update is reassuring that although caution is recommended, this procedure does seem safe and reasonable for continued investigation.
