Normal karyotype and cryptic reciprocal translocations in infertility

https://doi.org/10.25557/2073-7998.2025.10.106-110

Abstract

An examination of two families with reproductive dysfunction was conducted. In both families, the spouses had a normal karyotype based on the results of cytogenetic analysis. The study of the karyotypes of embryos during preimplantation genetic testing revealed the presence of partial aneuploidies in the terminal regions of chromosomes. A molecular cytogenetic analysis was performed using specific DNA probes for candidate subtelomeric regions of chromosomes. The women were found to have a balanced translocation: in the first case, between the terminal regions of chromosomes 1 and 10, and in the second case, between chromosomes 7 and 17.
