Abstract/OtherAbstract:
The primary aim of this study was to gain more insight into maturation arrest of spermatogenesis (MA) and its relationship with mutations in genes essential for meiosis. The study also investigated the possibility that mutations in human meiosis genes cause a milder phenotype and that, in such cases, meiosis could potentially be completed with the production of mature germ cells having an abnormal chromosomal constitution causing miscarriage. Among 40 patients with MA, five changes were observed that also predicted alterations at the amino acid level. However, since these changes were also present in men with normozoospermia in equal frequencies, it was assumed that these changes are single nucleotide polymorphisms. Among 46 patients with recurrent miscarriages, two additional changes were detected predicting an alteration at the amino acid level. One change was detected in controls. However, the second heterozygous change, detected in a conserved functional domain of the SYCP3 gene, was absent in >200 controls. These preliminary results stress the need to further investigate the relationship between abnormalities in meiosis genes and the formation of gametes with abnormal chromosomal constitution. More research is also necessary to determine the impact and frequency of such changes before implementing mutation screening in genetic counselling.
