We genotyped families of cystic fibrosis sib pairs homozygous for F508del-CFTR who represent extreme clinical phenotypes at informative microsatellite markers spanning a 38 Mb region between CFTR and 7qtel.
In an international, multicenter, cross-sectional study, we collected data on CFTR genotype and cardiopulmonary exercise tests in patients with cystic fibrosis who were ages 8 years and older.
Since targeting all the myriad defects individually could be quite challenging, it will be prudent to identify a process which controls almost all disease-promoting processes in the CF airways including underlying CFTR dysfunction.
Cystic fibrosis (CF) lung disease severity is largely independent on the CF transmembrane conductance regulator (CFTR) genotype, indicating the contribution of genetic modifiers.
This study expands the mutation spectrum of CFTR in patients of Chinese origin and further emphasizes the necessity of MLPA analysis in mutation screening for CF patients.
These in vivo results, consistent with prior in vitro findings, indicate that the drug treatments restore near-normal function to S945L-CFTR, and support the use of ivacaftor as a treatment for CF patients who carry this allele.
A conservative assessment of the major genetic causes of idiopathic chronic pancreatitis: data from a comprehensive analysis of PRSS1, SPINK1, CTRC and CFTR genes in 253 young French patients.
Cystic fibrosis (CF) is an autosomal recessive disease caused by the loss of function of the cystic fibrosis transmembrane conductance regulator (CFTR) protein which primarily acts as a chloride channel.
A 3-bp deletion in the CFTR gene (F508del, the most prevalent mutation involved in cystic fibrosis) was used as a model, in a single-tube procedure for each nucleotide to be tested.
A screening approach based on single-strand conformation analysis and direct sequencing of genomic polymerase chain reaction products has allowed us to detect the molecular defects on 95.4% of the CF chromosomes within the coding region and splice sites of the cystic fibrosis transmembrane conductance regulator (CFTR) gene.
The cystic fibrosisDeltaF508 mutation is commonly found in the general population and has been shown to result in a reduced number of CFTR molecules at the surface of epithelial cells.
