Cystic fibrosis is caused by a change, or mutation, in a gene called CFTR (cystic fibrosis transmembrane conductance regulator). The protein in this gene controls the flow of salt and fluids in and out of your cells. If the CFTR gene doesn’t work properly, a sticky mucus builds up in ...
Are there signs you’re a cystic fibrosis carrier? You won’t have any symptoms if you are only a carrier, which means that one of your two CFTR genes has a CF mutation. You may pass CF on to a child if your partner is also a carrier. The only evidence that you’re a carrier w...
Approximately one in every 25 people of European descent is a carrier for the cystic fibrosis gene, having one normal gene and one CF gene. Since cystic fibrosis is recessive, both copies of the gene have to be CF genes to cause the symptoms that occur in about 1 in every 2500 children....
Cystic fibrosis is caused by defects in the cystic fibrosis gene, which codes for a protein transmembrane conductance regulator (CFTR) that functions as a chloride channel and is regulated by cyclic adenosine monophosphate (cAMP). Mutations in theCFTRgene result in abnormalities of cAMP-regulated chl...
There are many gene defects that can cause cystic fibrosis and, depending on their severity, worsen the condition as well. Cystic fibrosis can be inherited, but only if both parents are carriers. If only one of the parents is a carrier, the child is unlikely to develop it even though that...
Cystic fibrosis (CF) is an autosomal recessive disorder that is common in individuals of European descent. It is caused by mutations in the CFTR gene, which encodes the CF transmembrane conductance regulator (CFTR) protein. These mutations result in defective chloride (Cl-) channels. Mandated new...

Cystic fibrosis is a progressive, genetic disorder that affects the lungs, pancreas and other organs. This lifelong condition is caused by mutations in the cystic fibrosis transmembrane conductance regulator (CFTR) gene. To have CF, a person must inherit two copies of the mutated CFTR gene, getti...
What causes cystic fibrosis? People with CFinheritedtwo copies of a defective or mutated CF gene, meaning each parent was a carrier for CF. Called the cystic fibrosis transmembrane conductance regulator (CFTR) gene, this mutation prevents the CFTR protein from working properly. ...
The variability of cystic fibrosis lung disease and the variable expressivity of mild CFTR alleles complicate genetic counseling for this autosomal recessive disorder. Widespread implementation of newborn screening programs among populations with significant cystic fibrosis mutation carrier frequencies is ...
