Prenatal testing for conditions such as Downs syndrome, Autism and other genetic disorders isn't really about curing them. At best, it gives parents advanced warning so they can work on changing their expectations and child rearing strategies to suit the coming child, plan early intervention strategies to help it, and seek out the resources they need to educate themselves about their childs condition. What actually happens is that the babies are aborted as soon as the test results are confirmed. In the UK there is no foetal age limit on terminations if the foetus is found to have a disability. ANY disability, even mild or non-life threatening ones. The foetus could be a day away from birth when it is aborted and that's ok. Disabled people are percieved as non-people, a burden on their families and a burden on society's resources. At university I did a bioethics course that covered this issue. The class (over 200) voted almost unanimously that selective terminations were a good thing because the resources used to care for the disabled could be used elsewhere and (sic) knowingly allowing the birth of a disabled child (in this case Downs syndrome) would prevent couples having more children as they would have to devote so much time and resources to their disabled children, so the births of the disabled children should be prevented as they infringe the rights of the as of yet unconcieved normal children that the parents possibly could have. Parents are too scared, ignorant or prejudiced to consider rearing a disabled child, and I doubt there is anything that can realistically be done to change this. Prejudice against people who are "other", especially if they are pervieved as defective, is too deeply ingrained in the human psyche.
