Our Survey Is Now Closed
The RDCRN research survey for rare disease patients and their families about impacts of COVID‑19 is now closed. If you completed our survey, thank you for your participation. If you chose to share your contact information, we may follow up with you in the future with additional study opportunities and to learn more about the ongoing impact of COVID-19 on your life. We are working to compile survey results and will share those on this website when available.
