  • The cystic fibrosis transmembrane conductance regulator (CFTR) is defective in cystic fibrosis (CF). This protein is a channel that sits on the surface of cells and transports chloride and other molecules, such as bicarbonate. The gene that encodes the CFTR protein, which is also called CFTR, is located on chromosome 7. Mutations in this gene lead to CF. Since the discovery of the CFTR gene in 1989, more than 2,500 mutations have been identified.

  • A gene is the basic unit of heredity. Genes are responsible for the physical characteristics that each person has (like eye color, facial features, and many health conditions). Each gene occupies a certain location on a chromosome (a thread-like material that is located in the nucleus of every single cell in the body). Chromosomes come in 23 pairs, and each chromosome carries thousands of genes.

  • Cystic fibrosis (CF) is caused by genetic mutations that affect the cystic fibrosis transmembrane conductance regulator (CFTR) protein. These mutations can impact the synthesis and transfer of the CFTR protein to the apical membrane of epithelial cells, as well as influencing the gating or conductance of chloride and bicarbonate ions through the channel. CFTR dysfunction results in ionic imbalance of epithelial secretions in several organ systems, such as the pancreas, gastrointestinal tract, liver and the respiratory system. Since discovery of the CFTR gene in 1989, research has focussed on targeting the underlying genetic defect to identify a disease-modifying treatment for CF. Investigated management strategies have included gene therapy and the development of small molecules that target CFTR mutations, known as CFTR modulators. CFTR modulators are typically identified by high-throughput screening assays, followed by preclinical validation using cell culture systems. Recently, one such modulator, the CFTR potentiator ivacaftor, was approved as an oral therapy for CF patients with the G551D- CFTR mutation. The clinical development of ivacaftor not only represents a breakthrough in CF care but also serves as a noteworthy example of personalised medicine.

  • May 14, 2015 · Cystic fibrosis is an autosomal recessive disease caused by mutations in the cystic fibrosis transmembrane conductance regulator (CFTR ) gene.

  • Cystic fibrosis is an autosomal recessive, monogenetic disorder caused by mutations in the cystic fibrosis transmembrane conductance regulator (CFTR) gene. The gene defect was first described 25 years ago and much progress has been made since then in our understanding of how CFTR mutations cause disease and how this can be addressed therapeutically. CFTR is a transmembrane protein that transports ions across the surface of epithelial cells. CFTR dysfunction affects many organs; however, lung disease is responsible for the vast majority of morbidity and mortality in patients with cystic fibrosis. Prenatal diagnostics, newborn screening and new treatment algorithms are changing the incidence and the prevalence of the disease. Until recently, the standard of care in cystic fibrosis treatment focused on preventing and treating complications of the disease; now, novel treatment strategies directly targeting the ion channel abnormality are becoming available and it will be important to evaluate how these treatments affect disease progression and the quality of life of patients. In this Primer, we summarize the current knowledge, and provide an outlook on how cystic fibrosis clinical care and research will be affected by new knowledge and therapeutic options in the near future. For an illustrated summary of this Primer, visit: Cystic fibrosis is caused by mutations in cystic fibrosis transmembrane conductance regulator (CFTR), which encodes a transmembrane ion channel on epithelial cells. Here, Ratjen et al. highlight that, although CFTR dysfunction affects many organs, lung disease is responsible for the vast majority of morbidity and mortality.
