Cftr 508 phenylalanine mutation
WebThe most frequent mutation is the deletion of phenylalanine at position 508 (F508del), which leads to distinct defects in channel gating and cellular processing. In last years, several thiazole containing small molecules, endowed with dual F508del-CFTR modulator activity, proved to be able to target these defects. DeltaF508 (ΔF508), full name CFTRΔF508 or F508del-CFTR (rs113993960), is a specific mutation within the CFTR gene involving deletion of three nucleotides spanning positions 507 and 508 of the CFTR gene on chromosome 7, which ultimately results in the loss of a single codon for the amino acid phenylalanine … See more Cystic fibrosis transmembrane conductance regulator (CFTR) is a membrane protein and anion channel in vertebrates that is encoded by the CFTR gene.

WebThe most common mutation causing CF is the deletion (delta) of a single phenylalanine (F) in position 508 within a putative helix located in NBF1. CF patients bearing this deltaF508 mutation frequently experience chronic lung infections, particularly by Pseudomonas aeruginosa, and have a life span that rarely exceeds the age of 30. Webnevertheless, how CFTR gene mutations cause tissue dam-age. The most common mutation in CF patients corresponds to a deletion of three base pairs, which results in the loss of phenylalanine at amino acid position 508 of the CFTR protein (DF508).10 This mutation is considered to cause misfolding of CFTR protein so that it is retained in the
WebMutations in the CFTR gene cause the CFTR protein to malfunction or not be made at all, leading to a buildup of thick mucus, which in turn leads to persistent lung infections, destruction of the pancreas, and complications in other organs.
