I have researched this one a bit. 23 and me is pretty easy and convenient but it is incomplete and can be a little misleading. I suggest you get their test and then run your data through promethease for better insights. I'd be happy to help anyone that needs it.

Too right I recently got the result that I have a "32 percent increased chance” of developing Parkinson’s disease. Freaked me out for some time till I learned that means I have a 2% chance of getting the disease.

You don't need to bother with 23andme and their prices (several hundred bucks if I recall). If you are willing to share the data (and let's face it that's gonna happen anyway) you can get a free sequencing from the Personal Genome Project.
