CFTR Mutations in Congenital Absence of Vas Deferens
A qualitative diagnosis of infertility requires attention to female and male physical abnormalities, endocrine anomalies and genetic conditions that interfere with reproduction. Many genes are likely to be involved in the complex process of reproduction. Cystic fibrosis (CF) incidence varies in different White people populations (a higher incidence of CF is observed in northern–western European...
متن کاملCFTR mutations altering CFTR fragmentation
Most CF (cystic fibrosis) results from deletion of a phenylalanine (F508) in the CFTR {CF transmembrane-conductance regulator; ABCC7 [ABC (ATP-binding cassette) sub-family C member 7]} which causes ER (endoplasmic reticulum) degradation of the mutant. Using stably CFTR-expressing BHK (baby-hamster kidney) cell lines we demonstrated that wild-type CTFR and the F508delCFTR mutant are cleaved into...
متن کاملCFTR Gene Mutations
Objectives: CF, caused due to abnormal transport of chloride, sodium and bicarbonate ions across epithelial cell membranes, is a multi-organ disorder. More than 1000 mutations causing CF, have been identified in the CFtR gene, of which AF508 is the most severe, predominant mutation. However, data on CF in India is limited. Also, facilities for CF diagnosis are not available at all diagnostic ce...
متن کاملScreening of two closed mutations in CFTR gene of Iranian infertile men with non-obstructive azoospermia
Background The genetic association between cystic fibrosis transmembrane conductance regulator (CFTR) gene mutations and male infertility due to congenital bilateral absence of vas deferens (CBAVD) is well established. Mutant CFTR, however may also be involved in the etiology of male infertility in non-CBAVD cases. The present study was conducted to estimate the frequency of ΔI507 and ΔF508 CFT...
متن کاملTransmembrane helical interactions in the CFTR channel pore
Mutations in the Cystic Fibrosis Transmembrane Conductance Regulator (CFTR) gene affect CFTR protein biogenesis or its function as a chloride channel, resulting in dysregulation of epithelial fluid transport in the lung, pancreas and other organs in cystic fibrosis (CF). Development of pharmaceutical strategies to treat CF requires understanding of the mechanisms underlying channel function. Ho...
