Cftr classes
WebCurrent available treatments for CF include the use of medications that target the various defects in the CFTR protein. One class of drugs is called CFTR modulators. There are three categories of modulators called correctors, potentiators, and amplifiers. 1-3 These modulators can’t cure CF or restore full function of the CFTR protein, but ...

The CFTR gene is approximately 189 kb in length, with 27 exons and 26 introns. CFTR is a glycoprotein and is found on the surface of many epithelial cells in the body. CFTR consists of 5 domains, which include 2 transmembrane or membrane-spanning domains, 2 nucleotide-binding domains and a regulatory domain. The transmembrane domains are each connected to a nucleotide bin… WebExamples of class V mutations are 3849 + 10kb CtoT and 2789 + 5GtoA. 5 . Class VI mutations destabilize the mature CFTR protein at the cell surface. 5 The unstable protein is quickly degraded, so that the number of CFTR channels in the cell membrane is reduced. 4 Examples of class VI mutations are Q1412X, N287Y, and possibly dF508. 5
