Further delineation of complex chromosomal rearrangements in fertile male using multicolor banding

Molecular Cytogenetics, 2008
Background Complex chromosomal rearrangements (CCRs) are defined as structural chromosomal rearrangements with at least three breakpoints and exchange of genetic material between two or more chromosomes. Complex chromosomal translocations are rarely seen

Clinical and Molecular Characterization of 46 Patients With Beckwith–Wiedemann Spectrum and Uniparental Disomy of 11p15

American Journal of Medical Genetics Part A, EarlyView.
ABSTRACT Beckwith–Wiedemann spectrum (BWSp) is an overgrowth disorder characterized by its main clinical features macrosomia, macroglossia, and abdominal wall defects. BWSp is caused by (epi)genetic chromosome 11p15 alterations with approximately 20%–27% of patients exhibiting mosaic paternal uniparental disomy of chromosome 11p15 (pUPD11p15).

Replicative and non-replicative mechanisms in the formation of clustered CNVs are indicated by whole genome characterization.

PLoS Genetics, 2018
Clustered copy number variants (CNVs) as detected by chromosomal microarray analysis (CMA) are often reported as germline chromothripsis. However, such cases might need further investigations by massive parallel whole genome sequencing (WGS) in order to ...

Animal models for human contiguous gene syndromes and other genomic disorders

Genetics and Molecular Biology, 2004
Genomic disorders refer to a group of syndromes caused by DNA rearrangements, such as deletions and duplications, which result in an alteration of normal gene dosage.

Systematic Review of Females With Intellectual Disability and MECP2 Duplication

American Journal of Medical Genetics Part A, EarlyView.
ABSTRACT MECP2 Duplication Syndrome (MDS) is a rare, X‐linked neurodevelopmental disorder typically affecting males. Females with MDS have been reported and are compiled here. We conducted a systematic review (PROSPERO CRD420250652426) of PubMed, EMBASE, and Google Scholar extracting individual participant data.

UBE3A Dosage Imbalance as a Molecular Framework Linking Angelman Syndrome and Dup15q‐Associated Autism Phenotypes

American Journal of Medical Genetics Part B: Neuropsychiatric Genetics, EarlyView.
ABSTRACT UBE3A is a dosage‐sensitive HECT E3 ubiquitin ligase whose neuronal expression is shaped by genomic imprinting at the 15q11.2‐q13 locus. Opposite directions of UBE3A dosage imbalance contribute to distinct neurodevelopmental phenotypes: loss of maternal UBE3A underlies Angelman syndrome, whereas maternally derived 15q11.2‐q13 copy‐number gains,

Genome‐wide network analysis identifies the lncRNA‐92467/miR‐205‐5p/PTPRM/CAMs axis in a rat model of hypoxic pulmonary hypertension

Animal Models and Experimental Medicine, EarlyView.
The pathogenesis of hypoxic pulmonary hypertension (HPH) remains unclear. In this study, we explored its key regulatory mechanisms using animal models, RNA sequencing, and cellular assays. We found that lncRNA‐92467 functions as a ceRNA, binding miR‐205‐5p, and thereby upregulating PTPRM, inhibiting abnormal proliferation and migration of endothelial ...

A Novel Chromosomal Translocation Identified due to Complex Genetic Instability in iPSC Generated for Choroideremia

Cells, 2019
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
