The article present the results of retrospectively analyzed children (4424 boys) with mental and psychomotor retardation, congenital malformations and/or developmental micro anomalies. 23 children had various forms of Y chromosome dysomy syndrome. The frequency of this syndrome in the studied cohort was 0.52%; and in this connection the authors discussed the role of Y-chromosome in the origin of mental retardation. Besides, the chromosome instability in sex and somatic cells is supposed to be a common mechanism of different chromosomal anomalies. The authors discussed the possibility of cytogenetic and molecular cytogenetic diagnosis, and also clinical polymorphism of the syndrome. The authors established the necessity of molecular cytogenetic technologies in the diagnosis of different forms of the syndrome, including mosaic forms and isodicentric chromosomes-connected forms. The severity of clinical symptoms doesn’t depend on presence of regular or mosaic forms of the syndrome. The study assumes a possible connection of clinical polymorphism with mosaisism, associated with the presence of abnormal cells (cell lines) in different tissues, together with the role of Y chromosome in the origin of mental retardation in children with Y- chromosome disomy syndrome and other chromosomal anomalies. The authors underline the necessity of molecular cytogenetic diagnosis of different forms of the syndrome for correct medical and genetic consultation.

Cytogenetic Analyses

The Talpidae family has a highly stable karyotype. Most of the chromosome studies in this mammal group, however, employed classical cytogenetic techniques. Molecular cytogenetic analyses are still scarce and, for example, no repeated DNA sequences have been described to date. In this work, we used sequence analysis, chromosomal mapping of a LINE1 retroelement sequence, as well as chromosome painting with a whole Y chromosome probe of T. occidentalis to compare the karyotypes of 3 species of the genus Talpa (T. occidentalis, T. romana, and T. aquitania). Our results demonstrate that in Talpa genomes LINE1 sequences are widely distributed on all chromosomes but are enriched in pericentromeric C-band-positive regions. In addition, these LINE1 accumulate on the Y chromosomes of the 3 Talpa species regardless of their euchromatic or heterochromatic condition. Chromosome painting shows that the Y chromosomes in these 3 species are highly conserved. Interestingly, they share sequences with heterochromatic blocks on chromosome pairs 14 and 16 and, to a lesser degree, with the pericentromeric regions of other autosomes. Together, our analyses demonstrate that the repetitive DNA content of chromosomes from Talpa species is highly conserved.
