Cystic fibrosis (CF) is an autosomal recessive disorder of Cl − and Na + transport. The vast majority of CF patients have deleterious mutations in an epithelial Cl − channel called the CF transmembrane conductance regulator (CFTR). In contrast, defects in the epithelial Na + channel (SCNN1) have been associated with phenotypes …
