The CFTR gene is made up of 27 exons that encode its gene makeup and is found on the long (q) arm of chromosome 7 at locus 31.2. Exons are DNA fragments that provide the code for a protein structure. CFTR functions as phosphorylation and ATP-gated anion channel, increasing the conductance for certain anions (e.g. Cl ) to flow down their electrochemical gradient.

WebThe CFTR gene is a protein that functions as a chloride channel. A chloride channel helps maintain the proper balance of salt and water within a cell. A mutation in CFTR causes a dysfunction of the salt and water balance. This causes dehydration of the secretions (thick mucous) and excessive loss of salt in sweat.
