Our Impact on Rare Diseases

NCATS is the heart of rare diseases research at NIH. We speed the development of new rare disease treatments by focusing on approaches that can address more than one disease at a time.

Delivering Hope for Rare Diseases

There are more than 10,000 known rare diseases and only a few hundred have safe, effective treatments. In the United States, rare diseases affect about 1 in 10 people. 

We are working hard to address the significant and often unmet needs of those affected by rare diseases. Through our research programs and other activities, we partner with patients, advocates, clinicians and researchers. Together, we have moved promising therapies into clinical trials, advanced therapeutic development tools and technologies, created widely used informational resources, and raised awareness of the rare disease public health challenge. 

Our research priorities include shortening the time to diagnosis, spurring multiple treatments at a time, and making it easier and more efficient for scientists to discover and develop rare disease therapies. Because most rare diseases are genetic, we are especially focused on developing gene-targeted approaches for treating groups of rare diseases. We are also leveraging newer approaches, such as genetic analysis and machine learning, to help health care providers diagnose people with rare diseases and help people with rare diseases access the most current and reliable information.
