One Child, Three Biological Parents – End of Diseases?

Last week, The Telegraph announced that within three years, it will be possible to have three biological parents for any one embryo using in-vitro fertilization.  Why would anyone pursue such a technique?  To “eradicate hereditary disease.”  You can read the full artcle below:

This controversial method proposes that transferring a tiny fraction of DNA from a different donor than only the parents will result in a child without mitochondria-related diseases.  (Mitochondrial diseases are often severe and incurable, including muscular dystrophy and ataxia).  Researchers believe they can wipe out such diseases within a generation.  Children would also retain DNA from both their mother and their father.  The genetic implant of a third person is described as being “as minimal as changing the batteries in a camera.”

Researchers are also placing great emphasis on needing public support, before current laws (which would prevent such an operation) become changed.  Strong opposition comes from “groups who oppose embryo research and claim genetic engineering can result in serious defects.”

What is perhaps equally interesting to the article itself is the poll available on the website.  The Telegraph asks: “Should scientists be allowed to develop treatment that would result in babies with three parents?”  Three possible answers are provided: “No – this kind of genetic interference is unethical” ; “Yes – this could stop diseases completely” ; and “Only if there are very tight restrictions covering the circumstances in which this treatment could be used.”

One questions how far is “too far” in assessing possible “diseases.”  It is interesting that a strong majority (close to 50% of pollers) feel that such a procedure is beneficial and a blanket solution, (choosing “Yes” as an answer”) over either “No” (26%) or “Only with tight restrictions.”  (24%)
