Cystic fibrosis (CF) is an autosomal recessive disease caused by several mutations involving the cystic fibrosis transmembrane conductance regulator (CFTR), a gene encoding for a chloride/bicarbonate channel expressed on the apical side of epithelial cells of different organs, including lungs, pancreas, and testis [1,2]. This evidence concerns the gene CFTR and cystic fibrosis.
