If you’re like me, you could find out at age 38 who your true biological father is, and contact him for the first time. It may spiral you into an identity crisis, wondering if you should change your name and the name of your children. Here’s the thing though, my biological dad didn’t share his DNA. His first cousin did, and I contacted him.
As others have said, because you share your DNA with all of your relatives, it’s already not 100% private. One or more of your relatives has already tested their DNA. The most genetic privacy you can get would be for nobody to know who you’re related to. How tightly do you protect that information? Changing your name would be a good first step.
There's enough DNA registered to find almost literally anyone in the US that way now. It's how they caught the golden state killer. A partial DNA match will narrow down 350,000,000 people to less than 100. Then it's just a matter of gettin' a box of jelly donuts and gettin' down to some good old fashioned police work with a game of Guess Who.
If you're related to anyone that has done a DNA test ever, you're already in the system.
