Abstract
Chromosome abnormalities play a crucial role in reproductive failure. The presence of numerical or structural aberrations may induce recurrent pregnancy loss or primary infertility. The main purpose of our study was to determine the types and frequency of chromosomal aberrations in infertile patients and to compare the frequency of structural aberrations to a control group. Karyotyping was performed in 1489 men and 780 women diagnosed with reproductive failure between 2010 and 2020. The control group included 869 male and 1160 female patients having cytogenetic evaluations for reasons other than infertility. Sex chromosomal aberrations were detected in 33/1489 (2.22%) infertile men and 3/780 (0.38%) infertile women. Structural abnormalities (e.g., translocation, inversion) were observed in 89/1489 (5.98%) infertile men and 58/780 (7.44%) infertile women. The control population showed structural chromosomal abnormalities in 27/869 (3.11%) men and 39/1160 (3.36%) women. There were significant differences in the prevalence of single-cell translocations between infertile individuals (males: 3.5%; females: 3.46%) and control patients (males: 0.46%; females: 0.7%). In summary, this is the first report of cytogenetic alterations in infertile patients in Hungary. The types of chromosomal abnormalities were comparable to previously published data. The prevalence of less-studied single-cell translocations was significantly higher in infertile patients than in the control population, supporting an earlier suggestion that these aberrations may be causally related to infertility.

Self-reported effects of perceived social support on marital quality in balanced translocation patients and their spouses undergoing preimplantation genetic testing in China: actor-partner interdependence model.

Abstract
This study aimed to analyse the relationship between perceived social support and marital quality in balanced translocation patients and their spouses undergoing a preimplantation genetic testing (PGT) treatment cycle in China. The authors assessed the actor and partner effects of perceived social support on marital quality in patient-spouse dyads using a dyadic analysis approach. In total, 59 couples were assessed using self-report questionnaires for marital quality and perceived social support. There were significant differences in marital quality between patients and their spouses (p=.0025) based on the APIM (actor-partner interdependence model) analyses. The perceived social support of both patients (p=.0076) and spouses (p<.001) had a significant effect on individual marital quality for actor effects. Partner effects showed that patients' perceived social support had a significant effect on spouses' marital quality (p=.0156) and the spouses' perceived social support had a significant effect on patients' marital quality (p=.0084). The findings indicate that the level of perceived social support affected both his/her own marital quality and that of his/her spouse.Impact StatementWhat is already known on this subject? Infertility and reproductive treatments affect both partners, that is, the couple as a unit and have a negative impact on an individual's marital satisfaction and social relationships.What do the results of this study add? There are significant differences in marital quality between balanced translocation patients and their spouses. Perceived social support significantly correlated with marital quality in both the actor and partner effects.What are the implications of these findings for clinical practice and/or further research? Health professionals should provide couple-based interventions involving both patients and spouses throughout the PGT treatment to improve perceived social support, thereby improving their marital quality.

A Novel Chromosomal Translocation Identified due to Complex Genetic Instability in iPSC Generated for Choroideremia. Cells 2019; 8:cells8091068. [PMID: 31514470 PMCID: PMC6770680 DOI: 10.3390/cells8091068] [Citation(s) in RCA: 4] [Impact Index Per Article: 0.8] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/13/2019] [Revised: 08/28/2019] [Accepted: 09/07/2019] [Indexed: 12/19/2022] Open
Abstract
Induced pluripotent stem cells (iPSCs) have revolutionized the study of human diseases as they can renew indefinitely, undergo multi-lineage differentiation, and generate disease-specific models. However, the difficulty of working with iPSCs is that they are prone to genetic instability. Furthermore, genetically unstable iPSCs are often discarded, as they can have unforeseen consequences on pathophysiological or therapeutic read-outs. We generated iPSCs from two brothers of a previously unstudied family affected with the inherited retinal dystrophy choroideremia. We detected complex rearrangements involving chromosomes 12, 20 and/or 5 in the generated iPSCs. Suspecting an underlying chromosomal aberration, we performed karyotype analysis of the original fibroblasts, and of blood cells from additional family members. We identified a novel chromosomal translocation t(12;20)(q24.3;q11.2) segregating in this family. We determined that the translocation was balanced and did not impact subsequent retinal differentiation. We show for the first time that an undetected genetic instability in somatic cells can breed further instability upon reprogramming. Therefore, the detection of chromosomal aberrations in iPSCs should not be disregarded, as they may reveal rearrangements segregating in families. Furthermore, as such rearrangements are often associated with reproductive failure or birth defects, this in turn has important consequences for genetic counseling of family members.
