At-Home Genetic Testing–What Information Should Companies Be Able to Provide?

When asked about your origins, do you tell others you’re 50% German and 20% Irish and a little bit Polish, Dutch, and French? Have you ever wondered exactly where your family is from? For around $200 you can unlock the secrets of your own genetics. Many online services including 23andMe, Ancestry.com, Orig3n, and others offer kits to test your genes. Simply spit in a tube and send it off with the fee and they’ll send back stats about your roots. Pretty cool, right? But what about the other information they can provide? Your risks for certain cancers, diseases, and other disorders could be given to you in hard numbers. But what do you do with that information?

When these tests first came out, they handed you an armload of information, but no means to interpret it. The FDA realized that this information was causing people unessescary panic, so they froze the ability to provide information about genetic predisposition to diseases, only allowing companies to provide the public with their family history of origin. This past April (2017) the FDA partially lifted this ban, allowing 23andMe to provide you with your risk for 10 diseases. According to CNN, these diseases are: “Parkinson’s; late-onset Alzheimer’s; celiac disease; a movement disorder called early-onset primary dystonia; a disorder that elevates your risk for lung and liver disease called Alpha-1 antitrypsin deficiency; a blood clotting disorder Factor XI deficiency; an organ and tissue disorder called Gaucher disease type 1; a red blood cell condition known as G6PD; hereditary hemochromatosis, an iron overload disorder; and hereditary thrombophilia, a blood clot disorder.”

While it’s amazing that this information is available to you at a low cost, what do you do with it? So you find out you have a 90% of developing Alzheimer’s. There is no cure, no treatment, nothing you can do about it. I would highly recommend talking to a genetic counselor. They can discuss with you what these numbers mean, and what you can do about it. Always keep in mind that your results are not a diagnosis. Even a high risk of a disorder does not guarantee that you will develop it.

Genetic testing is an amazing scientific advancement. If you can afford it, I would recommend getting your genes tested. You can learn so much about your family history and yourself. Just be aware of the accuracy of the tests and what to do with the information you receive. Happy learning!
