Cftr 508 phenylalanine mutation
WebDeletion of phenylalanine-508 appears to cause disease by abrogating normal biosynthetic processing and thereby resulting in retention and degradation of the mutant protein within the endoplasmic reticulum. ...

WebThe deletion of Phenylalanine in position 508 of the Cystic Fibrosis Transmembrane conductance Regulator (F508del-CFTR) is the most common mutation in CF patients: the deleted protein, not properly folded, is degraded. To date no commercial drugs are available.

WebMay 1, 2000 · CFTR is an epithelial chloride channel, mutations in which cause cystic fibrosis (Riordan et al. 1989). The predicted topology of CFTR includes two repeats of six membrane-spanning segments, two … WebSep 25, 2007 · The most common mutation, a deletion of the phenylalanine at position 508 (ΔF508), disrupts processing of the protein. Nearly all human CFTR-ΔF508 is retained in the endoplasmic reticulum and degraded, preventing maturation to the plasma membrane. In addition, the F508 deletion reduces the activity of single CFTR channels.
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. WebDifferences in severity are directly due to CFTR function which is based on the severity of CFTR mutation. This knowledge has proven useful for designing therapy for individual mutations and mutation classes. The discovery and US Food and Drug Administration approval of Kalydeco® (ivacaftor) in early 2011 marked the beginning of a new era of ...

This mutation leads to the loss of phenylalanine-508 (F508) and a silent codon change (SCC) for isoleucine-507 (I507-ATC¡ATT). F508 CFTR is misfolded and degraded by endoplasmic re-ticulum-associated degradation (ERAD). We have dem-onstrated that …
WebMar 3, 2004 · In individuals with cystic fibrosis (CF; 219700), Kerem et al. (1989) identified deletion of 3 basepairs in exon 10 of the CFTR gene, leading to deletion of phenylalanine at codon 508 (delta-F508). The exon in which the delta-F508 mutation occurs has been corrected to exon 11; see, e.g., Sharma et al. (2014).
