Detailed Description:

23andMe has created a web-based Parkinson's Research Community to examine how genes and environment are related to risk for Parkinson's. Conducting the study online can significantly accelerate the pace of this research, which seeks to enroll 10,000 people with Parkinson's. The online study design allows people diagnosed with Parkinson's to participate from any location ( It's free to participate, and anyone that has been diagnosed with Parkinson's by a physician is eligible. Enrollment is on-going and participants can sign up at any time. Participants provide a saliva sample for DNA testing and fill out surveys online about their symptoms, experiences and environmental exposures. 23andMe uses this information to conduct Genome Wide Association Studies to find genes that are significantly correlated with Parkinson's. In return, participants can see their own genetic information, including whether they carry certain mutations associated with Parkinson's, but they can also choose not to view their results. 23andMe provides materials and support to explain what the results mean, through online tutorials, videos and the patient liaison ( Additionally, participants are kept informed of research discoveries made in the project and how this relates to them.
