Many people have genetic disorders and don't know it. I did not know of a inherited condition I have, abbreviated 'MTHFR' (methylenetetrahydrafolate reductase) until I had genetic testing done.
Now I'm starting to understand the effect this condition may have had on my life, and I recommend to anyone to have themselves tested, it's easy and they send you everything in the mail to collect a few drops of your blood. Cost me $300.
