What is Cystic Fibrosis

Cystic fibrosis (CF) is a life-limiting, autosomal recessive genetic disorder caused by mutations in the CFTR gene, which encodes a chloride channel critical for salt and water transport across epithelial surfaces. The most common mutation is F508del, but more than 2,000 variants are known. Defective or absent CFTR protein disrupts chloride and bicarbonate movement, resulting in thick, sticky secretions in organs such as the lungs, pancreas, gastrointestinal tract, and reproductive system. This leads to impaired mucociliary clearance, persistent infection, inflammation, and progressive tissue damage, especially in the respiratory and digestive systems. Clinically, CF presents with chronic respiratory infections, persistent cough, progressive lung damage, pancreatic insufficiency, malnutrition, and male infertility. Diagnosis relies on clinical features, elevated sweat chloride testing, newborn screening with immunoreactive trypsinogen, and genetic analysis for CFTR mutations. Ancillary tests, such as nasal potential difference measurements, may support diagnosis in atypical cases. Treatment includes CFTR modulator therapies (e.g., elexacaftor/tezacaftor/ivacaftor), mucolytics like dornase alfa, inhaled antibiotics (such as aztreonam), and supportive care to manage infections and improve nutrition. Advances in therapy have significantly improved life expectancy and quality of life, but CF remains a serious, chronic disease requiring lifelong multidisciplinary management.

Cystic fibrosis (CF) is fundamentally driven by dysfunction of the Cystic Fibrosis Transmembrane Conductance Regulator (CFTR), a chloride and bicarbonate channel whose genetic mutations impair epithelial ion transport. This leads to dehydrated, viscous secretions in the airways and other organs, setting the stage for chronic infection and tissue damage. Additional molecular targets implicated in CF pathogenesis include Peptidase Inhibitor 3 (PI3), which regulates the protease-antiprotease balance and modulates airway inflammation; Deoxyribonuclease 1 (DNASE1), which degrades extracellular DNA to reduce mucus viscosity; and Retinoic Acid Receptor Gamma (RARG), a nuclear receptor involved in epithelial differentiation and repair. Together, these targets represent key mechanistic nodes in the complex molecular network underpinning CF.
