Why cystic fibrosis is common?
It's an inherited condition. A child needs to inherit one copy of the mutated gene from each parent to develop cystic fibrosis. If they only inherit one copy from one parent, they won't develop it. However, they will be a carrier of that mutated gene, so they could pass it along to their own children in the future.
Is cystic fibrosis very common?
Cystic fibrosis is a common genetic disease within the white population in the United States. The disease occurs in 1 in 2,500 to 3,500 white newborns. Cystic fibrosis is less common in other ethnic groups, affecting about 1 in 17,000 African Americans and 1 in 31,000 Asian Americans.
What is the root cause of cystic fibrosis?
Cystic fibrosis is caused by a change, or mutation, in a gene called CFTR (cystic fibrosis transmembrane conductance regulator). This gene controls the flow of salt and fluids in and out of your cells. If the CFTR gene doesn't work the way it should, a sticky mucus builds up in your body.

Why can't people with cystic fibrosis be near each other?
For people with CF, being close to others with the disease puts them at greater risk of getting and spreading dangerous germs and bacteria. This is called cross‐infection. Not only are these dangerous germs difficult to treat, but they can also lead to worsening symptoms and faster decline in lung function.

Can a child have cystic fibrosis if parents are not carriers?
A person with one non-functional copy of the gene is a carrier. Carriers for CF have no symptoms, but can pass the non-functioning gene on to their children. An individual must inherit two non-functioning CF genes – one from each parent – to have CF.
How common is it to carry cystic fibrosis?

How common is cystic fibrosis around the world?
There are close to 40,000 children and adults living with cystic fibrosis in the United States (and an estimated 105,000 people have been diagnosed with CF across 94 countries). Approximately 1,000 new cases of CF are diagnosed each year.
Who gets cystic fibrosis?
People with CF have inherited two copies of a mutated CF gene, meaning each parent was a carrier for CF. In the U.S., one in every 31 carries a mutation of the CF gene. 5 Called the cystic fibrosis transmembrane conductance regulator (CFTR) gene, this mutation prevents the CFTR protein from working properly. There are more than 1,700 known mutations of the disease. 6
How common is cystic fibrosis in white people?
Cystic fibrosis is one of the most common genetic disorders in white people in the United States, occurring in one of every 3,200 live births. It is less common in African Americans (1 in 17,000), Asian Americans (1 in 31,000) and Native Americans.
