There are over 7,000 rare diseases, mostly affecting the nervous system, with 200 new ones identified each year. More than 300 million people worldwide have a rare disease.

A rare disease in the U.S. affects fewer than 200,000 people. Because so few people have each disease, research funding is limited, slowing the discovery of treatments.

At Kennedy Krieger Institute, we work to develop novel and innovative treatments for rare diseases, helping patients live fulfilling lives.
