Cystic Fibrosis Transmembrane Conductance Regulator Gene Variations in Coding and Noncoding Regions in Congenital Bilateral Absence of the Vas Deferens Dependent Infertility

Cystic fibrosis transmembrane conductance regulator gene mutations in infertile males with congenital bilateral absence of the vas deferens.

Congenital bilateral absence of the vas deferens (CBAVD) is characterized by azoospermia and male infertility. Mutations in the cystic fibrosis transmembrane conductance regulator (CFTR) gene are associated with cystic fibrosis (CF), the most common autosomal recessive disorder in Caucasians. Recent publications on CBAVD raised the question whether CFTR gene mutations are responsible for CBAVD ...

Cystic fibrosis transmembrane conductance regulator (CFTR) gene abnormalities in Indian males with congenital bilateral absence of vas deferens & renal anomalies

BACKGROUND & OBJECTIVES The role of cystic fibrosis transmembrane conductance regulator (CFTR) gene mutations in congenital bilateral absence of vas deferens and unilateral renal agenesis (CBAVD-URA) has been controversial. Here, we report the cases of five Indian males with CBAVD-URA. The objective was to evaluate the presence or absence of CFTR gene mutations and variants in CBAVD-URA. The fe...

Detection of cystic fibrosis transmembrane conductance regulator (CFTR) gene rearrangements enriches the mutation spectrum in congenital bilateral absence of the vas deferens and impacts on genetic counselling.

BACKGROUND Mutations in the cystic fibrosis (CF) transmembrane conductance regulator (CFTR) gene have been widely detected in infertile men with congenital bilateral absence of the vas deferens (CBAVD). Despite extensive analysis of the CFTR gene using varied screening methods, a number of cases remain unsolved and could be attributable to the presence of large gene rearrangements, as recently ...

Comprehensive and rapid genotyping of mutations and haplotypes in congenital bilateral absence of the vas deferens and other cystic fibrosis transmembrane conductance regulator-related disorders.

Available commercial kits only screen for the most common cystic fibrosis transmembrane conductance regulator (CFTR) mutations causing classic cystic fibrosis and for the Tn variant in IVS8. However, full scanning of CFTR is needed for the diagnosis of patients with cystic fibrosis or CFTR-related disorders (including congenital bilateral absence of the vas deferens) bearing rare mutations. Sta...
