Service of Genetic Tests: Do You Want to Know or Not?

Most of my friends and colleagues present themselves for medical tests and checkups when they should while I drag my feet attending to only the most essential. My philosophy: Who wants to know?

So it would be very unlikely for me to send away to 23andMe at any time in my life to learn whether one or more of the 10 diseases the company tests for, such as late-onset Alzheimer’s or Parkinson’s, will afflict me.

There are many chomping at the bit to find out and now the FDA says that they can: No more need to pass by a genetic counselor or through a doctor for the privilege. Spit into a receptacle to provide a sample of saliva; send $199 and voila—you’ll soon know about how or if you relate to any of the 10.

Jessica Boddy, NPR summarized info on an FDA press release: “The testsBlood pressure test assess genetic risk for the conditions but don’t diagnose them, the FDA says. The agency urges consumers to use their results to ‘help to make decisions about lifestyle choices or to inform discussions with a health care professional.’”

The FDA’s Center for Devices and Radiological Health director Jeffrey Shuren said “‘it is important that people understand that genetic risk is just one piece of the bigger puzzle, it does not mean they will or won’t ultimately develop a disease.’ Other known factors that can play into the development of disease include diet, environment and tobacco use.”

We already know about the importance of a healthy diet and the risks of tobacco use as they relate to all sorts of diseases–so nothing new here–and I can’t do much about my environment. Loosening regulations on power plants and reducing fuel efficiency standards for cars is going to impact everyone in a bad way. I wonder if people in 45′s administration realize that they, their children and grandchildren might suffer as a result?

Referring to test results Boddy quoted a Harvard Medical School professor who warned that the “information is complicated.”

Nobody in the article spoke up for those who don’t want to know. Do you want to learn what your genetic makeup indicates might happen? Would you be irritated if at 68 you sold your house and all your belongings to move into an adult care facility and found yourself at 95 in great form still with no signs of late-onset Alzheimer’s? Would knowing spoil what’s left of your life be it 20 or 70 years? Would you cancel your marriage plans if you wanted to have children and you learned that both you and your intended had similar genetic indicators for a nasty disease?
