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 dominated by renal disease (systemic pseudohypoaldosteronism type I and Liddle syndrome). We report two non-classic CF patients without CFTR mutations who have novel deleterious mutations in the β-subunits of SCNN1 in the absence of overt renal disease.
