Cystic fibrosis is a genetic disease and individual must inherit two non-functioning CF genes that is one from each parent to have CF. Both parents must have at least one copy of the defective gene and people who have only one copy of the defective CF gene are called carriers but they do not have the disease. Many couples who have a child with CF have no family history of cystic fibrosis

Cystic fibrosis affects cells that produce mucus, sweat, and digestive juices and also it causes these fluids to become thick and sticky. They block tubes, ducts, and passageways.

Symptoms include cough, repeated lung infections, inability to gain weight, and fatty stools. Treatments for this disease may ease symptoms and reduce complications.
