From Bioedge, a bioethicist named Arthur Caplan of the University of Pennsylvania stated:
“Few will argue that finding out early in a pregnancy if a male fetus has a fatal form of muscular dystrophy or Rett Syndrome -- a nervous disorder that causes males to die in utero -- would be beneficial to many families. But outside of that kind of testing, everything about the early testing of fetal genes for sex identification spells ethical trouble. And, as the techniques for the analysis of fetal DNA become more and more accurate and affordable, it is likely to reshape the debate over abortion.” ~ New York Times, Aug 10; MSNBC, Aug 9
I hope that Caplan isn't hinting in his first sentence that abortion should be an option if the baby is found to have Rett Syndrome. It is evil and immoral to kill an innocent human being. I hope that instead he is indicating that it is better for the parents to know that their baby may have an awful disease so that they can prepare.
I believe that in most cases this test is going to be used unethically.
