When I did 23&me I was most excited to learn about my ancestry. My 23&me results were somewhat disappointing. Both sides of my family claim some Native American ancestors, but 23&me says that I am 98.4% European and of that 79% Northern European with the rest being non-specific European. I am only 0.8% Native American, which is enough to show that there might be something in my past, but not as recent as some family members would like to say. I have a small amount of German/French ancestry (3.4%), but the cool part about that is that it is all located together on one of my two second chromosomes. So I have almost an entire chromosome that is from German/French ancestry. The 0.8% Native American is also together in one piece indicating that it came from one place, which is pretty cool. I could be possible that the genes from my Native American ancestor were lost during crossing over events in my parents, grandparents, great-grandparents, etc. So there still could be more Native American ancestry than what shows up. So I now know a lot more about my extended heritage, but nothing ground breaking or exciting was found.
Probably one of the coolest ancestry things I found is that I am 3% Neanderthal putting me into the 88th percentile. That is pretty cool, and makes sense with my Northern European ancestry.
When it came to my health results, there was only one thing that was major for me: I have two copies of the APOE ε4 variant. This increases my risk for Alzheimer's to 39.9%. If you have a family history, you can assume that this is correct or even raised. My grandmother and two of her siblings are currently suffering from the disease. My risk factor for this is extremely high, and this is pretty scary. I'm not really sure what all there is that I can do about this. There are no confirmed ways to prevent it. I'm not guaranteed to get the disease, but with my family history, I have to admit that it is extremely likely.
There really wasn't anything else significant that I found. It knew my hair color, and eye color. One other thing I found interesting is that I am "likely a sprinter." I've never been much for exercising, but running has always been my preferred thing to do if I am going to exercise regularly. Maybe I should start running more often.
