We have identified all known sufferers of cystic fibrosis (CF) alive in the Grampian region, north east Scotland, on 1 January 1989. DNA samples were obtained for a prevalence study of the common mutations with near to complete ascertainment. A relatively high prevalence of the delta F508 mutation was found (82%), with one of four mutations being present on 92% of CF chromosomes. The high preva...

CFTR is a PKA activated Cl(-) channel expressed in the apical membrane of fluid transporting epithelia. We previously demonstrated that c-Cbl decreases CFTR stability in the plasma membrane by facilitating its endocytosis and lysosomal degradation in human airway epithelium. The most common mutation associated with cystic fibrosis, deletion of Phe508 (∆F508), leads to a temperature sensitive bi...

In this paper the fitness of the ∆F508 heterozygote is assessed and the age of the ∆F508 mutation in the cystic fibrosis locus is estimated. Data from three microsatellite loci are applied. The analysis is performed conditional on the present-day frequency of the ∆F508 mutation and based on assumptions about the demographic history of the European population and the mutation rate in the three m...

BACKGROUND Cystic fibrosis is usually diagnosed in childhood, but a number of patients are not diagnosed until adulthood. The aim of this study was to investigate whether patients diagnosed at an older age had a different genetic constitution, manifestations of disease, and prognosis from those diagnosed at an early age. METHODS Clinical data and results of lung function tests and DNA analysi...

A male 14 months old had deferential abnormalities during orchidopexy. The genetic study demonstrate cystic fibrosis (∆F508 / ∆F508). A literature review of the genetic alterations observed in patients with congenital unilateral and bilateral absence of the vas deferens was underwent as well as the role of cystic fibrosis trans membrane conductance regulator gene on fertility.
