What is Cystic Fibrosis?

Cystic Fibrosis is a chronic disease that affects the lungs and digestive system of about 30,000 children and adults in the United State (70,000 worldwide). A defective gene and its protein product cause the body to produce unusually thick, sticky mucus that clogs the lungs and leads to life-threatening lung infections. The mucus also obstructs the pancreas and stops natural enzymes from helping the body break down and absorb food.
