Cystic fibrosis is a progressive, genetic disease that causes persistent lung infections and limits the ability to breathe over time. In people with cystic fibrosis, a defective gene causes a thick buildup of mucus in the lungs, pancreas and other organs. In the lungs, mucus clogs the airways and traps bacteria, leading to infections, extensive lung damage and respiratory failure.

The mission of the Cystic Fibrosis Foundation is to cure cystic fibrosis and to provide all people with CF the opportunity to lead long, fulfilling lives by funding research and drug development, partnering with the CF community, and advancing high-quality, specialized care.
