Access to information about our DNA is now easily available. This genetic information is wonderful and daunting for all of us, and perhaps especially valuable for adoptees, whether US or international.
It’s relatively inexpensive ($99) now to find out what percent of your DNA comes from what population (Sub-Saharan Africa, Europe, South America, etc.). Adopted people of mixed background can get an accurate breakdown of information that they may never have received nor otherwise could find out. A friend of mine, adopted from Colombia, found out she is Mayan, Middle Eastern, and Spanish/French.
You can also find out about medical matters, such as whether you are a carrier for cystic fibrosis, Tay-Sachs disease, sickle cell anemia, and many more. You can learn your genetic risk for diabetes, macular degeneration, Parkinson’s, and other serious conditions. You can discover how your genetic makeup could impact sensitivity to certain medications and drugs, such as Plavix and Coumadin.
Because the DNA results are all part of a global database, it is possible to find previously unknown relatives, from close family to distant cousins. In terms of search, for adopted people, this is huge.
I drew the information above largely from the website of one of the most popular sites, www.23andme.com. The “23” refers to the number of pairs of chromosomes we humans have.
The testing is done via saliva, about a half teaspoon’s worth. Young children can be tested; the kit is modified for folks who can produce saliva but not spit.
Adoptees are often missing their own medical histories. Every visit to a doctor’s office can be a reminder of loss, guesswork, and uncertainty. Writing “Adopted” and crossing out the Family History section can be frustrating. DNA testing eliminates some of the mystery, and fills in some of the blanks.
Of course, this genetic information opens a lot of potentially complex new doors. Finding out about potential future medical conditions could be frightening.
I still will say, though, that information is power. These days, we all have to be really strong advocates for our physical and mental health. Genetic testing gives us more information to work with, and allows us to engage our health care providers more effectively.
I’ve offered to get the testing kits for each of my (young adult) adopted children. They are considering it, and I can understand the need to take some time to decide. I’m going to get the testing done on myself. I’m not adopted, and I feel pretty confident that my ethnicity will be fully Irish. My mom died at 74 from cancer; she suffered with interstitial cystitis for years. Dad, now 83, is in great physical health, and also in the early stages of Alzheimer’s. So I have some sense for the possibilities, and, at this point in my life, would rather have the information than wonder about it.
Everyone should have that option.
Here are some interesting sites to explore and consider:
