Cystic fibrosis. Cystic fibrosis (CF) is caused by a recessive allele. You need to inherit two copies of the faulty allele to have CF. If you just have one copy of the faulty allele, you are a carrier but have no symptoms. If two carriers have a child between them, there is a one in four chance of that child having the disorder.
What Is Cystic Fibrosis? Cystic fibrosis (SIS-tik fi-BRO-sis), or CF, is an inherited disease of the secretory (see-KREH-tor-ee) glands. Secretory glands include glands that make mucus and sweat. Inherited means the disease is passed from parents to children through genes. People who have CF inherit two faulty genes for the diseaseâone from each parent. The parents likely don't have the disease themselves.
