Cystic fibrosis (CF) is a genetic disease affecting approximately 30,000 children and adults in the United States. A defective gene causes the body to produce an abnormally thick, sticky mucus that clogs the lungs and leads to life-threatening lung infections. These thick secretions also obstruct the pancreas, preventing digestive enzymes from reaching the intestines to help break down and absorb food.

More than 10 million Americans are unknowing, symptomless carriers of the defective CF gene. An individual must inherit two defective CF genes -- one from each parent -- to have CF. Each time two carriers conceive, there is a 25 percent chance that their child will have CF; a 50 percent chance that the child will be a carrier of the CF gene; and a 25 percent chance that the child will be a non-carrier.

CF occurs in approximately one of every 3,200 live Caucasian births (in one of every 3,900 live births of all Americans). About 1,000 new cases of CF are diagnosed each year. More than 80 percent of patients are diagnosed by age three; however, nearly 10 percent of newly diagnosed cases are age 18 or older.

People with CF have a variety of symptoms including: very salty-tasting skin; persistent coughing, at times with phlegm; wheezing or shortness of breath; an excessive appetite but poor weight gain; and greasy, bulky stools. Symptoms vary from person to person due, in part, to the more than 1,000 mutations of the CF gene.

According to the CF Foundation's National Patient Registry (PDF), the median age of survival for a person with CF is 33.4 years. As more advances have been made in the treatment of CF, the number of adults with CF has steadily grown. Today, nearly 40 percent of the CF population is age 18 and older. Adults, however, may experience additional health challenges including CF-related diabetes and osteoporosis. CF also can cause reproductive problems - more than 95 percent of men with CF are sterile. But, with new technologies, some are becoming fathers. Although many women with CF are able to conceive, limited lung function and other health factors may make it difficult to carry a child to term.

The mission of the CF Foundation is to assure the development of the means to cure and control CF and to improve the quality of life for those with the disease. It funds medical research and care programs which are improving the length and quality of life for people with CF.
