CFTR modulators address various problems caused by different types of CFTR mutations. (cff.org)
Cystic fibrosis is caused by mutations, or errors, in the cystic fibrosis transmembrane conductance regulator (CFTR) gene, which result in either no CFTR protein being made or a malformed CFTR protein that can't perform its key function in the cell. (cff.org)
Protein production mutations, which include nonsense and splice mutations, interfere with the production of the CFTR protein. (cff.org)
If the CFTR gene has a nonsense mutation, the protein-building instructions contain an early stop signal that causes the production of the CFTR protein to stop prematurely. (cff.org)
Watch this webcast (starting at 3:03) to see how a nonsense mutation affects production of the CFTR protein and how the mutation might be corrected to make normal CFTR protein. (cff.org)
Splice mutations interfere with the ability of the cell to correctly read the instructions for making the CFTR protein. (cff.org)
When a mutation causes an amino acid to be deleted or an incorrect amino acid to be added, the CFTR protein cannot form its correct 3-D shape and function properly. (cff.org)
The F508del mutation removes a single amino acid from the CFTR protein. (cff.org)
The drug combination Trikafta ® (elexacaftor/tezacaftor/ivacaftor) works by enabling CFTR protein with an F508del mutation to fold in a more correct shape, and then activates the protein to allow more chloride to pass through. (cff.org)

All human beings have two copies of the cystic fibrosis transmembrane conductance regulator (CFTR) gene. (apegrade.com)
Therefore, cystic fibrosis is caused by mutations in the gene-producing CFTR protein. (apegrade.com)
CFTR gene mutations can disrupt the normal functioning or production of the CFTR protein present in lung cells and the rest of the body. (apegrade.com)
These include splice and nonsense mutations, and they alter CFTR protein production. (apegrade.com)
Splice mutations interfere with these instructions, making the cell unable to read them, leading to an incorrect CFTR protein building. (apegrade.com)
The most common cystic fibrosis is the F508del which deletes one amino acid from the CFTR protein, and thus it is unable to be in its correct 3-D shape (Naehrig, Chao, and Naehrlich, 2017). (apegrade.com)
Cystic fibrosis can be caused by any of the thousands of identified mutations in the CFTR protein, an ion channel that allows chloride ions to pass through. (wikipedia.org)
These mutations have been classified into Class I to V, with Class III mutations causing defective channel gates in CFTR despite normal expression of the protein. (wikipedia.org)
Negulescu also led the discovery of another cystic fibrosis drug, lumacaftor, which is known as a "corrector" as it acts as a chaperone to help the CFTR protein fold correctly. (wikipedia.org)
Thus, it can be used in patients with Class II mutations, which create misfolded CFTR protein that cannot reaching the cell surface. (wikipedia.org)
