I also have PD in my immediate family; my father died from PD two years ago, my mother also has PD, and last year I was diagnosed with PD. I have also offered to be a test subject along with my Mom when I was at UCSF last summer. Haven't heard anything about the test as of yet but would be very interested in the results if any of yours (worried about my children and grandchildren). Thanks Sherry 48/47
