About 30,000 Americans, and 70,000 people worldwide, are living with cystic fibrosis, caused by inheriting a flawed CF gene from each parent. The disease causes a sticky mucus to build up in the lungs, clogging them and leading to life-threatening infections.
Cystic fibrosis is a hereditary disease that causes the body to produce thick and sticky mucus that can clog the lungs and obstruct the pancreas. This genetic disease can be life threatening, and affects an estimated 30,000 children and adults in the US, with around 1,000 new cases diagnosed each year. Cystic fibrosis is most commonly diagnosed via a sweat test. 2  There are over 1,900 known mutations of the cystic fibrosis gene. 3  Even people with the same gene variation can have vastly different phenotypes, causing significant differences in symptoms and prognosis. 4  There is currently no absolute cure for cystic fibrosis.
