Cystic fibrosis (CF; OMIM # 219700) is a genetic autosomal recessive disease, caused by a defect in the cystic fibrosis transmembrane conductance regulator (CFTR) protein, an anionic channel present in the apical membrane of various epithelial cells, where it regulates electrolytic exchanges [1,2]. Here, CFTR is linked to cystic fibrosis.
