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.

# data[].attributes.body
In people with CF, mutations in the CFTR gene can disrupt the normal production or functioning of the CFTR protein found in the cells of the lungs and other parts of the body ...

People can be tested to see if they carry the CF gene, but because there are hundreds of specific CF gene mutations (not all of which are known), genetic testing for CF won't detect everyone who is carrying a CF gene.

People with CF get frequent lung infections that can damage their lungs over time and require strong antibiotics along with stays in the hospital. They may have trouble growing or gaining weight because of digestive problems.Adults with CF may also develop other illnesses, such as diabetes (when blood sugar is too high) or osteoporosis (a weakening of the bones).
