UK Government Backs Three-Person IVF 132

Posted by Soulskill from the US-republicans-introduce-defense-of-test-tubes-act dept.
Dupple writes "The U.K. looks set to become the first country to allow the creation of babies using DNA from three people, after the government backed the in vitro fertilization technique. It will produce draft regulations later this year and the procedure could be offered within two years. Experts say three-person IVF could eliminate debilitating and potentially fatal mitochondrial diseases that are passed on from mother to child. Opponents say it is unethical and could set the UK on a 'slippery slope.' They also argue that affected couples could adopt or use egg donors instead. Mitochondria are the tiny, biological 'power stations' that give the body energy. They are passed from a mother, through the egg, to her child. Defective mitochondria affect one in every 6,500 babies. This can leave them starved of energy, resulting in muscle weakness, blindness, heart failure and death in the most extreme cases."

              • Pray tell, why is denying an existence to a healthy child that could have been born instead of a partially or fully disabled child a better option?

                It's not an either or situation. If you have a disabled child, you are not denying a healthy child. Prior to conception there are zero children. At conception there is one child. That child is either healthy or disabled, but like Schroedinger’s cat, we don't know until we look. (That is true even if the mother or father have a predisposition for a genetic abnormality, at least for most abnormalities).

                You seem to be insinuating a line of reasoning that borders on fallacy. We don't know the full extent to which ALS is caused by the individual contributing factors. We don't even know if the genetic factors that seem to be partly responsible for it in many cases in any way contributed to his mental prowess. The same Stephen Hawking might have never developed ALS if his early life had been different. Given a slightly different prenatal and childhood development, genetically the same Stephen Hawking could have developed ALS without getting the brilliance in exchange. And many other people grew into brilliant minds without suffering from ALS.

                There's no reason to assume that a yet-unborn child that to your knowledge will get born disabled or preconditioned for disability with certainty will have an offsetting factor (such as scientific brilliance) with any higher probability than that a healthy child would be gifted.

                There is a genetic marker for ALS on chromosome 21 (I think) and a specific test for it. Although it does not run in families, it can be tested for in utero. As such, it would qualify in this discussion would it not? Even if a child born today is predestined to have ALS, just because they will not have the scientific brilliance of Hawking, are you stating that they should not be allowed to live? That sounds like an argument to kill them off unless they have some benefit for society.

                They matter. But show me one parent that would willingly choose a disabled child upon conception instead of a healthy one if given an option. Go on, just try.

                Again, that is an impossible argument, of course every parent would want their children to be healthy. However, if the mother and father have the dominate genetic traits that will lead to disabilities, it really doesn't matter how many tries they get, their children will have those traits. If only one does, then it is still better than a 50/50 chance the child will, depending on the marker. Even if neither do, there is still a 10% likelihood that there will be a disability.

                But, what your question really should be is of asking parents that have had a disabled child and what their views are about it. Would they have preferred their child had never been born? And while there are those that would agree with that sentiment, there are those that would not. Which comes back to the original question of
