Cystic+Fibrosis

The production of a protein in the lungs, pancreas, or other organs stops. This causes the cell to be unable to transport chloride ions, which leads to mucus build up and bacterial infections in the lungs.
 * Causes**


 * Symptoms**
 * Persistent diarrhea
 * Smelly or greasy stool
 * Frequent pneumonia
 * Chronic coughing
 * Salty skin
 * Poor growth

This disease occurs in both males and females equally, in about 1 in 2,500 births in the United States. Some people can be born with this disease but grow up completely unaffected. It is most common in Caucasians (1 in 3,300)
 * Incidence**

You have to receive two copies of the mutated gene to get Cystic Fibrosis. This is because the disorder is recessive.
 * Inheritance**

People with Cystic Fibrosis tend to have saltier sweat, so a test can be done to measure the amount of salt in a person's sweat. Another test that can be done is DNA testing, but this test is not as effective. It is only accurate 80%-85% of the time.
 * Testing and Screening**

Since nutritional problems can result from Cystic Fibrosis, enzyme supplements can be used to treat the problems. The build up of mucus in the lungs is the most prevalent of the symptoms, and although there is no cure for this, chest percussions and drugs can be used to relieve this symptom. When the lungs no longer work, a lung transplant can be done to extend life, but it will not eradicate the disease completely.
