Thoughts on prenatal testing

Saturday, September 6, 2008 Comments

I've been thinking about this all week, ever since Palin was announced as McCain's running mate. The media has been making a really big deal about the fact that "she knew ahead of time that her baby was going to have Down syndrome, and yet she decided to have the baby anyway." They say this with a sense of awe and/or surprise.

It seemed odd to me, until I learned that 90% of babies diagnosed with Down syndrome during pregnancy are aborted. 90%. I did a little research, and found that there are approximately 5,000 babies born with Down syndrome each year. So, if we assume that roughly 75% of those were diagnosed during pregnancy (just for the sake of estimating the impact), that's around 3,750 babies born with DS each year who were diagnosed during pregnancy. If that represents the 10% that are not aborted, that means there are another ~33,750 babies with Down syndrome that are NOT born each year. I don't want to start a debate on abortion, but that just breaks my heart.


But what happens if a test is developed that will diagnose autism during pregnancy? On the one hand, it would give parents time to research and prepare. But on the other hand, will we see 90% of autistic children aborted? I don’t even want to think about a world like that, and yet it has already happened in the case of Down syndrome and perhaps with other conditions that can be diagnosed prenatally. I don’t want to debate the broader “cure” issue, which I know is a hot-button topic, but I have to ask, is this what some people have in mind when they think of a cure for autism? Will there come a day when people say with amazement in their voices, “she knew her baby would have autism, and yet she decided to have the baby anyway?”
