What causes some people to have cystic fibrosis and others to not?

Cystic fibrosis is an example of a recessive disease. That means a person must have a mutation in both copies of the CFTR gene to have CF. If someone has a mutation in only one copy of the CFTR gene and the other copy is normal, he or she does not have CF and is a CF carrier.

Are you born with cystic fibrosis or can you develop it?

In the U.S., because of newborn screening, cystic fibrosis can be diagnosed within the first month of life, before symptoms develop. But people born before newborn screening became available may not be diagnosed until the signs and symptoms of CF show up.

How does a person with cystic fibrosis get it?

Cystic fibrosis, or CF, is a genetic disease. You cannot get it any other way besides inheriting one CF gene from each of your parents. Babies who get two of these defective genes will always develop the disease. A person who has one CF gene does not have cystic fibrosis, but is a carrier.

Why do people with cystic fibrosis cough up mucus?

This imbalance leads to thick, sticky mucus in the lungs, pancreas and other organs. The mucus coughed up from the respiratory tract is called sputum. Mucus that doesn’t clear is a breeding ground for bacteria and leads to these chronic lung infections in CF patients.

What kind of diabetes does cystic fibrosis cause?

There are two types of diabetes in people without cystic fibrosis: type 1 and type 2. Type 1 diabetes is an autoimmune disease that occurs when the body’s immune system attacks and destroys the cells in the pancreas that make insulin A hormone secreted by the pancreas that helps sugar leave the blood and enter the cells, where it is used for fuel.

How does a chronic lung infection affect cystic fibrosis?

Chronic lung infection damages epithelial cells surfaces and leads to inflammation, impairing the lung’s ability to function. It’s estimated over 80% of cystic fibrosis patients are killed by these kinds of chronic lung infections.

What are the risk factors of cystic fibrosis?

The greatest risk factor for cystic fibrosis is a family history of the disease, especially if either parent is a known carrier. The gene that causes cystic fibrosis is recessive. This means that in order to have cystic fibrosis, children must inherit two copies of the gene, one from each parent.

What are some interesting facts about cystic fibrosis?

8 Interesting Facts About Cystic Fibrosis. Cystic Fibrosis [CF] is a genetic disorder. It primarily affects the digestive and respiratory systems of those who have it. CF develops because of a defective gene that is on Chromosome 7 and it stops salt moving in and out of cells effectively. The result is an increased production of mucus and this clogs the airways and digestive systems.

What does cystic fibrosis mean?

Definition of cystic fibrosis. : a common hereditary disease that appears usually in early childhood, involves functional disorder of the exocrine glands, and is marked especially by difficulty in breathing due to mucus accumulation in airways, by faulty digestion due to a deficiency of pancreatic enzymes, and by excessive loss of salt in the sweat.

What does cystic fibrosis do?

Cystic fibrosis is an inherited disorder that causes severe damage to the lungs, digestive system and other organs in the body. Cystic fibrosis affects the cells that produce mucus, sweat and digestive juices. These secreted fluids are normally thin and slippery.
