Overview
Objective:
To present the results of molecular genetics analysis in men with reproductive disorders focusing on the DNA segments and genes which affect spermatogenesis.
Design:
Original article.
Setting:
Institute of Biology and Medical Genetics of the First Faculty of Medicine and General Teaching Hospital, Prague.
Methods:
One hundred and twenty-three patients identified with a fertility disorder were screened for mutations of the CFTR gene. In all patients were performed cytogenic analysis and assessment of Y-chromosome microdeletions. In 107 patients where the fertility was not detected by routine examination we performed an analysis for X-chromosome microdeletions (CNV64, CNV67, CNV69) and in certain genes necessary for normal spermatogenesis (AGFG1, CAPZA3, CNTROB, HOOK1, GOPC, SPATA16).
Results:
Our results did not reveal any negative efffects of X-chromosome microdeletion on spermatogenesis. Analysis of six genes showed in two patients in gene SPATA16 a homozygotic haplotype [1526C>T + 1577T>C] which can be most probably responsible for the fertility in two examined patients.
Conclusion:
According to our results we do not recommend introduction of X-chromosome microdeletions assays in areas CNV64 , CNV67 and CNV69 into routine diagnostic. Regarding the selected genes affecting spermatogenesis, our results showed that homozygotic haplotype [ 1526C>T + 1577T>C] in SPATA16 gene is very likely responsible for infertility in two of our patients. The above mentioned haplotype deserves attention in the investigation of male infertility.
