This manuscript reviews the frequencies, symptoms, testing, and reporting of genotypes with the 5T polythymidine tract which reduces splicing efficiency in the cystic fibrosis transmembrane conductance regulator (CFTR) gene in congenital bilateral absence of the vas deferens (CBAVD) patients and in patients and fetuses with cystic fibrosis-like symptoms.

The frequencies of both CFTR gene alterations and polymorphisms did not differ significantly between the control group and men with idiopathic nonobstructive azoospermia and subfertility, but were significantly increased in men with CBAVD (DeltaF508, p = 0.039; IVS8-5T, p = 0.006).

As the vas deferens seems to be one of the tissues most susceptible to a reduction in the normal CFTR transcripts levels, and as two mild mutations are sufficient to induce CBAVD phenotype, these findings raise the possibility that these uncommon variants may be a novel cause of CBAVD.

In monosymptomatic forms of cystic fibrosis such as congenital bilateral absence of vas deferens, variations in the TG(m) and T(n) polymorphic repeats at the 3' end of intron 8 of the cystic fibrosis transmembrane regulator (CFTR) gene are associated with the alternative splicing of exon 9, which results in a nonfunctional CFTR protein.
