Homozygosity of the cystic fibrosis (CF) gene allele IVS8-(5T) in a Tamil male with congenital bilateral absence of the vas deferens (CBAVD)

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...

Mutations in the cystic fibrosis gene in patients with congenital absence of the vas deferens.

BACKGROUND Congenital bilateral absence of the vas deferens (CBAVD) is a form of male infertility in which mutations in the cystic fibrosis transmembrane conductance regulator (CFTR) gene have been identified. The molecular basis of CBAVD is not completely understood. Although patients with cystic fibrosis have mutations in both copies of the CFTR gene, most patients with CBAVD have mutations i...

The genetic basis of congenital bilateral absence of the vas deferens and cystic fibrosis.

Congenital bilateral absence of the vas deferens (CBAVD) has long been thought to be a rare and distinct clinical and genetic entity. However, it occurs in 1-2% of the infertile male population (Jequier et al, 1985). Recently, this disorder has been shown to represent a mild (reproductive) form of cystic fibrosis (CF) (Anguiano et al, 1992). This finding mandates that proper genetic counseling ...

Potential role of cystic fibrosis genetic modifier factors in congenital bilateral absence of the vas deferens

Cystic fibrosis mutation screening in CBAVD patients and men with obstructive azoospermia or severe oligozoospermia.

Congenital bilateral absence of the vas deferens (CBAVD) found in otherwise healthy infertile males, is associated with a high incidence of mutated cystic fibrosis transmembrane conductance regulator (CFTR) alleles, and is considered a genital form of cystic fibrosis (CF). The CF gene may also be involved in the aetiology of male infertility in cases other than CBAVD. The present study was unde...
