lizzie's reply to my questions about analyzing for just one gene with links to more information.

Hi Paula,

In terms of the health topics covered in the 23andMe service, this is a growing list that is currently at 109 diseases and other health topics and they are summarized here: https://www.23andme.com/health/all/. I encourage you to take a few minutes to look over the list and read about the distinction between a clinical and a research report. I will note that we're currently a one-stop shop at 23andMe. When you sign up for our service you get everything, including ancestry information. Some people do not realize this. However, everyone can look at as much or as little of the information as they are interested in. If you don't want to look, it's pretty easy not to.

In terms of PD-specific markers, we currently check for the two most common (though still rare) known markers that are associated with PD. A summary of the state of the union on genetics and PD, which goes into a lot more detail on the genes -- particularly those included in the 23andMe service is here: http://spittoon.23andme.com/2009/03/...k-in-progress/

Let me know if you have any questions about this!

Lizzie
