Just a note: Chromosomal mutations usually lead to sterility.(Klinefelter's Syndrome, Turner Syndrome are the big ones)
Can you explain what the issue is here ?
@sigfried Bioethics. Some people I know are raising the issue of consent to have your genes modified. And while I do think making changes to an unborn person's genes is unethical, I don't think that it is the same thing as treating a chromosomal mutation.
So this is the genetic modification of Sperm and Eggs in order to prevent certain traits from being passed into prospective offspring. That is perfectly ethical to me.
