Cystic fibrosis is a genetic disorder that affects the respiratory and digestive systems. People with cystic fibrosis inherit a defective gene on chromosome 7 called CFTR (cystic fibrosis transmembrane conductance regulator).
Cystic fibrosis is a complex, chronic disease that primarily affects the lungs and digestive system. More than 30,000 children and adults in the United States have CF (70,000 worldwide). People with CF inherit two copies of a defective gene -- one copy from each parent -- that produces a faulty protein, causing a buildup of thick mucus in the lungs, pancreas and other organs. When mucus clogs the lungs, it can become very difficult for a person to breathe.
