Mutations of the CFTR gene in Turkish patients with congenital bilateral absence of the vas deferens.
Hum Reprod. 2004 May;19(5):1094-100. Epub 2004 Apr 7., [PMID:15070876]
Abstract [show]
BACKGROUND: Mutations of the Cystic Fibrosis Transmembrane Conductance Regulator (CFTR) can cause congenital bilateral absence of the vas deferens (CBAVD) as a primarily genital form of cystic fibrosis. The spectrum and frequency of CFTR mutations in Turkish males with CBAVD is largely unknown. METHODS: We investigated 51 Turkish males who had been diagnosed with CBAVD at the Hacettepe University, Ankara, for the presence of CFTR gene mutations by direct sequencing of the coding region and exon/intron boundaries. RESULTS: We identified 27 different mutations on 72.5% of the investigated alleles. Two-thirds of the patients harboured CFTR gene mutations on both chromosomes. Two predominant mutations, IVS8-5T and D1152H, accounted for more than one-third of the alleles. Five mutations are described for the first time. With one exception, all identified patients harboured at least one mutation of the missense or splicing type. Presently available mutation panels would have uncovered only 7-12% of CFTR alleles in this population cohort. CONCLUSIONS: Although cystic fibrosis is relatively rare in Turkey, CFTR mutations are responsible for the majority of CBAVD in Turkish males. Because of a specific mutation profile, a population-specific panel should be recommended for targeted populations such as CBAVD in Turkey or elsewhere.

Association of cystic fibrosis genetic modifiers with congenital bilateral absence of the vas deferens.

Abstract [show]
OBJECTIVE: To investigate whether genetic modifiers of cystic fibrosis (CF) lung disease also predispose to congenital bilateral absence of the vas deferens (CBAVD) in association with cystic fibrosis transmembrane conductance regulator (CFTR) mutations. We tested the hypothesis that polymorphisms of transforming growth factor (TGF)-beta1 (rs 1982073, rs 1800471) and endothelin receptor type A (EDNRA) (rs 5335, rs 1801708) are associated with the CBAVD phenotype. DESIGN: Genotyping of subjects with clinical CBAVD. SETTING: Outpatient and hospital-based clinical evaluation. PATIENT(S): DNA samples from 80 subjects with CBAVD and 51 healthy male controls from various regions of Europe. This is one of the largest genetic studies of this disease to date. INTERVENTION(S): None. MAIN OUTCOME MEASURE(S): Genotype analysis. RESULT(S): For single nucleotide polymorphism (SNP) rs 5335, we found increased frequency of the CC genotype among subjects with CBAVD. The difference was significant among Turkish patients versus controls (45.2% vs. 19.4%), and between all cases versus controls (36% vs. 15.7%). No associations between CBAVD penetrance and polymorphisms rs 1982073, rs 1800471, or rs 1801708 were observed. CONCLUSION(S): Our findings indicate that endothelin receptor type A polymorphism rs 5335 may be associated with CBAVD penetrance. To our knowledge, this is the first study to investigate genetic modifiers relevant to CBAVD.
