Cystic fibrosis is  an inherited disorder that damages your lungs, digestive tract and other organs . Genetics: Autosomal recessive defect in CFTR gene on chromosome 7, commonly a deletion of Phe508. Most common lethal genetic disease in Caucasian population. Pathophysiology: CFTR encodes an ATP-gated Cl− channel that secretes Cl− in lungs and GI tract, and reabsorbs Cl− in sweat glands. Most common mutation is misfolded protein  leading to protein retained in RER and not transported to cell membrane, causing decreased  Cl− (and H2O) secretion, increased intracellular Cl− results in compensatory increase in Na+ reabsorption via epithelial Na+ channels (ENaC)  leading to H2O reabsorption , hence abnormally thick mucus is secreted into
