Yes, thats right, we have a gene that determines if we can smell the scent of asparagus in our pee after we eat it. I guess God does have a sense of humor after all. Anyhow I am positive for that so next time I pee after eating Asparagus I will pay more attention to the smell of my pee . But besides that I wanted to know why I took Methyl B Complex I was getting side effects when everyone else I was recommending it too was sleeping better and having more energy. However, I felt jittery, agitated, and overly anxious over trivial things.
Needless to say, I ordered a 23andme test kit, and I finally got my results back. I learned that I am 45% Italian, and 20% Lithuanian, but I am more prone to Macular Degeneration. I also have a genetic variation that is great for elite athletes. (Wish I would have known this before) But I have a genetic marker in the ACTN3 gene. This marker controls whether muscle cells produce a protein(called alpha-actinin-3) that's found in fast-twitch muscle fibers. While some people don't produce this protein at all, almost all of the elite power athletes who have been studied have a genetic variant that allows them to produce the protein. This suggests that the protein may be beneficial at least at the highest levels of power-based athletic competition.
As cool as this was I found out that I have a COMT SNP and can't metabolize methylcobalamin, and I have a few other variations that explain why I act certain ways in certain situations. I never saw myself as a genetic counselor before, but I can definitely say I am so glad I completed this test and know what supplements I need based on my genetics rather than just taking something because I read it on a blog or magazine article. -sz
