What can be done to prevent the disease?

The gene for cystic fibrosis has been found on chromosome 7. There are many different abnormalities in this gene that can result in cystic fibrosis. Genetic testing can now identify more than 80% of people with an abnormal gene. People who come from families where someone has cystic fibrosis may choose to be tested for an abnormal gene. Testing for the abnormal gene can also be done on fetuses. In either case, couples can receive genetic counseling to decide how best to proceed with any family planning decisions.

What are the long-term effects of the disease?

People with cystic fibrosis have an increased risk of lung infections. Many of them will have repeated bouts of pneumonia. These usually lead to worsening lung disease. This, in turn, can result in respiratory failure and arrest.

Men and women with cystic fibrosis are often unable to have children because of abnormalities in their reproductive systems.

What are the risks to others?

Cystic fibrosis is not contagious but is passed genetically to children.
