Chromosomal phenotypes and submicroscopic abnormalities

open access: yesHuman Genomics, 2004
The finding, during the last decade, that several common, clinically delineated syndromes are caused by submicroscopic deletions or, more rarely, by duplications, has provided a powerful tool in the annotation of the human genome.

Controlled ovarian hyperstimulation parameters are not associated with de novo chromosomal abnormality rates and clinical pregnancy outcomes in preimplantation genetic testing

open access: yesFrontiers in Endocrinology, 2023
ObjectiveThis study aimed to determine whether controlled ovarian hyperstimulation (COH) parameters influence the incidence of de novo chromosomal abnormalities (> 4 Mb) in blastocysts and, thus, clinical pregnancy outcomes in preimplantation genetic ...

Diagnostic and prognostic role of soft ultrasound markers in prenatal detection and assessment of foetal abnormalities

open access: yesMenopause Review
Various soft markers can be detected in the ultrasonography of foetuses, which can be related to chromosomal abnormalities and increases the risk of abnormalities, or they can be considered as normal variations that can disappear due to the pregnancy ...

The two sides of chromosomal instability: drivers and brakes in cancer

open access: yesSignal Transduction and Targeted Therapy
Chromosomal instability (CIN) is a hallmark of cancer and is associated with tumor cell malignancy. CIN triggers a chain reaction in cells leading to chromosomal abnormalities, including deviations from the normal chromosome number or structural changes ...

Chromosomal Abnormalities in Hypoprolific Boars [PDF]

open access: yesHereditas, 2004
Four new chromosomal rearrangements are reported in the domestic pig: 3 reciprocal translocations, rcp(4;12)(p13;q13) in a crossbred boar, rcp(1;7)(q17;q26) in a Large White purebred boar, rcp(1;6)(q17;q35) in a purebred synthetic paternal line boar, and a pericentric inversion inv(2)(p13q11) in a crossbred boar.

The multifaceted role of chromosomal instability in cancer and its microenvironment

open access: yesCell, 2018
Chromosomal instability (CIN) is a hallmark of human cancer and it is associated with poor prognosis, metastasis, and therapeutic resistance. CIN results from errors in chromosome segregation during mitosis leading to structural and numerical chromosomal

Sequencing chromosomal abnormalities reveals neurodevelopmental loci that confer risk across diagnostic boundaries

open access: yesCell, 2012
SUMMARY Balanced chromosomal abnormalities (BCAs) represent a reservoir of single gene disruptions in neurodevelopmental disorders (NDD). We sequenced BCAs in autism and related NDDs, revealing disruption of 33 loci in four general categories: 1) genes ...
