Increasingly, unborn children undergo screening for genetic conditions that may impact their life outside of their mother's womb. The implications of this are immense: the ability to plan for the arrival of a special needs child, or the ability to somehow intervene to prevent the onset of such conditions are just two examples. However, the ability to screen unborn children also gives rise to many other options, such as the choice of termination of a pregnancy based on the knowledge of a child (potentially?) having a genetic condition. Some alternatives are more difficult to classify as 'right or wrong' (if that is indeed at all possible), such as the favourable selection of embryos during the process of in-vitro fertilisation (IVF). Clearly, there is a moral and ethical dilemma.
Should genetic screening be encouraged and used more often, or even made mandatory?
What actions are in/appropriate as a consequence of genetic screening on the unborn?
The principal medical justification for screening is as a tool to find the incidence of disease. Only with this knowledge can prevention and therapy take place. Clearly, genetic screening has the potential to improve the lives of many, by avoiding or relieving suffering. As science advances, many previously 'untreatable' conditions now have cures. Without screening, such medical advances would be for naught.
Screening, therefore, has an important place in medicine. Screens grant information that can fundamentally change important decisions. Such as whether to terminate a pregnancy that otherwise would have been continued. I want to narrow this thread to discussion of prenatal screening, rather than general genetic screening (such as screening for recessive genes for traits such as cystic fibrosis, which is important in it's own right, as potential partners who both hold this recessive gene have a 25% probability of passing this on as a dominant trait, and a 75% probability as a recessive gene), as it presents a larger and more important dilemma.
Genetic screening can open decisions that I find objectively wrong, and implications that can be considered morally reprehensible by many. There is a noticeable and growing link between genetic testing and selective abortion. As a Catholic, I find abortion wrong in it's own right. But there is the question of whether it is 'acceptable' as a response to information gained from prenatal screening. Is it appropriate, for instance, if one knows that their child will have a short/difficult/painful/humiliating existence, to terminate the pregnancy?
At an extreme - yet entirely possible - future, genetic screening grants the ability to draw distinctions among people based on genetic makeup, over which they have no control (except in the case of prenatal selection of genes, which is a completely related issue). Government and society, driven by utopianism, social Darwinism, racism, sexism, pragmatism and rationalism have proven the capacity for this - in the past and present. Once groups of people with certain characteristics (genetic traits) are isolated and granted fewer rights (such as the right to life) (by society or authority), we have significant issues. In history, we have the example of explicit black subjugation in the United States and elsewhere. More recently, China's 'one child policy' has created a societal ethos that discriminates against female children. Are we seeing a new-yet-similar phenomenon with disabled children? If all people are entitled to dignity, does prenatal genetic screening erode some of this?
What if we began to accept screening and subsequent selection for intelligence, blue eyes and blond hair? Are we taking the baby steps toward such an end?
As screenings become more widespread - or even mandatory - we are faced with more issues. Who has the right to genetic information? Surely an individual would benefit from, or at least be entitled to, the knowledge that they will develop a condition such as Huntington's disease, which does not reveal itself at birth. But do insurance agencies have the right to this information? Employers? Government? We do not choose our genes, and we certainly do not choose to have genetic disease, but if the information about us is revealed, the flood gates are thrust open. The systematic denial of insurance to people with late-stage genetic conditions is a potential eventuality, among others.
The notion of 'normalcy' is entirely subjective; for example, how can we be sure who is truly insane in an asylum? The patient or the doctor? 'Normalcy', however, is what is sought after by many when they choose prenatal screening. Are we searching for a world where people are without genetic 'flaws'? What would such a world be like?
To me, it would be a much different world, a worse world. It sounds nice to imagine a world where there are no sufferers of autism, Down's syndrome, cystic fybrosis, etc., etc.. But this is such an idealistic vision. We will never be without these conditions. My own brother is severly autistic (note that this is from the measles, mumps and rubella (MMR) vaccination*, not a genetic condition, but the principle of disabled rights still applies). Had his condition been genetic, and we had screened for it, and terminated the pregnancy as a result, I would be a completely different person. I'm sure anyone with a disabled sibling/child would say the same thing. He is responsible for teaching me tolerance, courage in the face of adversity, true beauty, and many other principles which I hold dear - all this without even speaking a single word to me.
My girlfriend told me something last night that relates to this. She asked (rhetorically) whether disabled people are here for a reason. While their form of existence may be difficult for themselves and those around them, they are still capable of joy, sadness, and love - attributes which make them just as human as anyone else. However, she also asked me if I, given the choice, would cure my brother's autism and have him as a 'normal' (whatever that is) brother. I said that I didn't know. Would my brother be any happier as a 'normal' child? It seems easy to say 'yes', such as if you were given the option of catching influenza, or not. However genetic conditions are so much more fundamental than influenza. They define an entire being. Far more than gender, race and age will ever. It sounds almost mean, then, to say that I love my brother as he is, and if forced the choice, I would say 'no'. If I could give him the choice, I would think he would choose to become 'normal'. This is strange in itself, but until you have lived my life, I doubt anyone would understand my reasoning.
More than anything mentioned thus far, I am personally concerned with the message that prenatal screening and subsequent abortion sends to those already living with the relevant genetic conditions. If given the choice between a disabled child and an 'ordinary' child, I doubt anyone would choose a disabled child. This is one of the most important promises of prenatal screening. So, if you have two embryos in front of you, one with autism, and one without autism, and you are deciding which to implant, I would expect you to pick the non-disabled one. If my brother could understand you when you spoke to him, how would you rationalise your decision? Would it be that you don't want another person to go through the same existence as my brother? But how do you have knowledge of that existence? Sure, you can tell that the disabled embryo will develop into a child that will never write a single word in their entire life, but you have no idea of the positive transformations that this child could cause, or the people they will learn to mutually love and respect. If you chose the non-disabled embryo, is it because the life of a disabled person is 'less equal'? Are they any less of a person because of their disability?
* Do not accept the claims made that MMR does not cause autism. There is no other explanation why my brother was an advanced learner immediately before his MMR vaccination, and then unable to function mentally immediately after it.
