Earlier this week, the media was again abuzz with the long-debated question of ethics when it comes to genetics and babies. The spark? 30-year-old Amanda Kalinsky—a woman diagnosed with Gerstmann-Straussler-Scheinker disease, a rare genetic neurological disorder that will lead to a slow, painful (and by all predictions) premature death. Though immediately after her diagnosis four years ago she vowed never to have children in order to cut off the head of the GSS snake, The New York Times reported that Amanda and her husband Bradley now have three children thanks to genetic testing and in-vitro fertilization.
The Kalinsky’s doctors created 18 embryos, tested all of them for the GSS gene, and implanted only the 12 without it. My first reaction is that this is an amazing breakthrough. A woman who wanted very badly to be a mother without passing on a terrible fate is now Mommy to three kids. Thanks to the availability of testing, she didn’t have to play Russian roulette and hope that a naturally-conceived child would be born without the gene —or have to debate aborting a fetus who tested positive for GSS during prenatal tests. She also didn’t have to forego motherhood (and her husband didn’t have to forego fatherhood). Not to mention, if doctors were able to do this for GSS—a rare disease—this could mean that we may be able to avoid passing along so many other diseases to future generations.
At the same time, this is not an equal-opportunity solution. The procedure cost the Kalinksys $20,000 for the first round—which they paid out of pocket because many insurers don’t cover this. So are we saying that only wealthy folk get to eliminate their diseases? What about people who can’t afford this? Are they subjected to the choice of taking their chances versus no children, at all?
But questions of who can take advantage of this aside, there is one huge question we need to ask ourselves: Should we be doing this at all? Will we continue to use this technology to prevent disease, or will it evolve into so much more? I am all for giving every child the best shot we can at a healthy, happy life. But is that really what’s going on? As of a recent international survey, 2 percent of over 27,000 uses of preimplantation diagnosis were actually to choose a child’s sex. Clearly, not a life and death matter.

I have a hard time believing that we will be able to keep the uses of this technology limited to “the right reasons.” And even if we do manage to pass laws and regulations about this technology (to keep it preventing diseases rather than brunettes), something tells me we may be drunk with power—believing that eliminating embryos of one gene means there are no unknown or other harmful genes lurking inside. But I have to say that in my opinion, if we have to put up with some people choosing girls over boys or blue-eyed kids over brown-eyed kids so that others can (to the best of their knowledge) choose healthy kids, then that’s the bullet we bite.
Yet, all this talk of genetic diagnosis reminds me of the other side of the genetics debate: genetic engineering. Last year Intelligence Squared sponsored a debate about whether or not we should prohibit the genetic engineering of babies. The most striking point was that genes do not occur in a vacuum. Genes interact with each other to create traits such as brown hair, fair skin, genius intelligence, or disease. By removing or altering a disease-causing gene, scientists cannot automatically declare victory. Disrupting the natural order could invent a new disease. It could cause the original gene to mutate and become alteration-resistant. Bottom line: We do not yet know the consequences of this.
When it comes down to it, here’s where I fall (for now): Genetic testing, yes. Genetic engineering, no.
