Cystic fibrosis (CF) is the most common fatal genetic disorder, arising due to mutations within the cystic fibrosis transmembrane conductance regulator (CFTR) gene, which alters ion fluxes in mucosal membranes, including the lung airways (Riordan et al. 1989; Cant et al. 2014). Here, CFTR is linked to cystic fibrosis.
