Cystic fibrosis is an autosomal recessive genetic disorder characterised by a mutation in the cystic fibrosis transmembrane conductance regulator (cftr) protein which acts as a chlorine channel that regulates water and ion levels across the epithelia. Causative mutations cf is caused by a mutation in the gene “cystic fibrosis transmembrane conductance regulator” (cftr) on chromosome seven 70% of all mutations in the gene involve the deletion of 3 nucleotides resulting in loosing the amino acid phenylalanine in position 508 , naming this mutation ∆f508 there are over 1500 other. Cystic fibrosis cystic fibrosis, is a genetic disorder of the exocrine glands, affecting children and young people median survival is 25 years in females and 30 years in males it is caused by a genetic abnormality in the cf transmembrane conductance regulator (cftr) gene that results in the disruption of chloride transfer across cell membranes.

Cystic fibrosis transmembrane conductance regulator (cftr) is a membrane protein and chloride channel in vertebrates that is encoded by the cftr gene [3] [4] the cftr gene codes for an abc transporter -class ion channel protein that conducts chloride [5] and thiocyanate [6] ions across epithelial cell membranes. The cftr gene provides instructions for making a protein called the cystic fibrosis transmembrane conductance regulator this protein functions as a channel across the membrane of cells that produce mucus, sweat, saliva, tears, and digestive enzymes. Rationale: cystic fibrosis (cf) transmembrane conductance regulator (cftr) modulators are a new class of medications targeting the underlying defect in cf ivacaftor (iva) and iva combined with lumacaftor (lum iva/lum) have been approved by the us food and drug administration (fda) for use in patients with cf. Dysfunction of the cystic fibrosis transmembrane conductance regulator (cftr) chloride channel causes cystic fibrosis, while inappropriate activity of this channel occurs in secretory diarrhea and polycystic kidney disease drugs that interact directly with cftr are therefore of interest in the.

Two cystic fibrosis transmembrane conductance regulator mutations have different effects on both pulmonary phenotype and regulation of outwardly rectifying chloride currents proceedings of the national academy of sciences, usa , 81: 1063-1073. Cystic fibrosis is found on the seventh chromosome and the mutation that leads to cystic fibrosis is called the cystic fibrosis transmembrane conductance regulator or cftr, which serves an important function in creating sweat, mucus and digestive juices. The cystic fibrosis transmembrane conductance regulator (cftr) expression core assists cystic fibrosis (cf) center investigators with the complex technology necessary to efficiently express cftr in experimental systems the core maintains a repository of reagents for studying cftr, including over 50. The cystic fibrosis transmembrane conductance regulator (cftr) gene was identified as the cause of cystic fibrosis (cf) 20 years ago since that time, over 1,500 mutations have been identified in the gene, although only a small fraction account for most of the cf-causing alleles.
