Cystic Fibrosis Overview
Cystic Fibrosis is a fatal genetic disease that occurs in children and young adults. There are around 30,000 people in the United States with cystic fibrosis. White newborns are more commonly affected, with 1 in 2,500-3,500 born with the condition. CF is not as prevalent in other ethnic groups. 
Thick mucus that clogs the airway and secreting glands characterizes cystic fibrosis. This condition affects just about every function of the body, including the lungs, pancreas, liver, intestines, sinuses, and sex organs. Medications like Ventolin inhaler can help with respiratory symptoms of this condition, but cystic fibrosis is a complicated disease, so read on to learn more.
A mutation of chromosome 7 on the CF gene causes the production of an abnormal protein (CFTR), which disrupts the chloride channels in cells. The defect in the chloride channels also causes sweat to become abnormally salty. There are over a thousand known defects that result from the abnormalities in the CFTR gene. The mutated gene prevents the regular flow of chloride ions and water across cell membranes in the lungs, pancreas, and other organs that produce mucus. This irregular flow creates the sticky mucus that causes problems all over the body.

A person with cystic fibrosis inherits two CFTR genes from their parents. If a child inherits one faulty CFTR gene, and one normal CFTR gene then the child is a “CF carrier.” If both the CFTR genes inherited by the parents are faulty, then the child will most likely have cystic fibrosis.
