The 23andMe unique research platform enables a large group of individuals to come together to provide valuable data for scientists studying rare diseases. This research data includes Genetic Information (using DNA from saliva) and Self-Reported Information about each participant's unique experiences (using responses from online surveys). Conducting research using this data may help find treatments for rare diseases. We believe that this study will enhance research into rare diseases by: Bringing together a large group of people to better understand how genes may influence these rare diseases. Expanding the geographic reach of the research study by enabling participation from home. Removing some of the time and cost barriers that can slow progress in other types of studies.
