- Introduction: Cystic fibrosis (CF) is the most prevalent, recessively inherited, disease in the western world. It is characterized by gene mutations in CF transmembrane conductance regulator (CFTR), a transmembrane ion channel that is responsible for chloride secretion in the airway passages. Althou
