Dear OMIM User,

At the request of the NIH and to ensure long-term funding for the OMIM project, we must diversify our revenue stream. We are determined to keep this website freely accessible. Unfortunately, it is not free to produce. Expert curators review the literature and organize it to facilitate your work. Over 90% of the OMIM’s operating expenses go to salary support for MD and PhD science writers and biocurators. Please consider making a donation now and again in the future. We need long-term secure funding to provide you the information that you need at your fingertips.

Thank you in advance for your generous support,
Ada Hamosh, MD, MPH
Scientific Director, OMIM
