title: [Detection of CFTR gene mutations in azoospermia patients with congenital unilateral absence of the vas deferens].
abstract: OBJECTIVE
  To discuss the results and significance of the detection of the CFTR gene mutation in azoospermia patients with congenital unilateral absence of the vas deferens (CUAVD).
  
  
  METHODS
  We collected peripheral blood samples from 6 azoospermia patients with CUAVD for detection of the CFTR gene mutations and single nucleotide polymorphisms. We analyzed the genome sequences of the CFTR gene in comparison with the website of the UCSC Genome Browser on Human Dec. 2013 Assembly.
  
  
  RESULTS
  Missense mutation of c. 592G > C in exon 6 was found in 1 of the 6 azoospermia patients with CUAVD and splicing mutation of c. 1210-12T[5] was observed in the noncoding region before exon 10 in 2 of the patients, both with the V470 haplotype in exon 11.
  
  
  CONCLUSIONS
  Mutations of the CFTR gene can be detected in azoospermia patients with CUAVD and the detection of the CFTR gene mutation is necessary for these patients.
