What kind of pattern inheritance cystic fibrosis?
A person who has only one mutated copy of the CFTR gene is called a carrier. Carriers do not have cystic fibrosis themselves, but they can pass the mutated gene on to their children.
If both parents are carriers, there is a 1 in 4 chance that each of their children will have cystic fibrosis. There is also a 1 in 2 chance that each of their children will be a carrier.
Cystic fibrosis is the most common life-threatening genetic disorder in the United States. It affects about 30,000 people in the United States and about 70,000 people worldwide.
