Predisposition to Aneuploidy in the Oocyte
Cytogenetic and Genome Research, 2011While the incidence of predisposition to aneuploidy in the oocyte increases with age, there is also evidence of increased incidence in young women with recurrent miscarriage, recurrent aneuploidy, or recurrent implantation failure after in vitro fertilization. There is evidence from mouse models and from observations in humans that follicle-stimulating

Aneuploidy in the driving seat
Nature Reviews Genetics, 2021Attempts to understand the role of aneuploidy in tumorigenesis have been hampered by conflicting results. Now, two new mouse models described in Genes and Development provide evidence that chromosome instability-induced aneuploidy drives T cell lymphomagenesis.

Analyses of ploidy levels in progenies from 2x x 2x, 2x x 4x, 4x x 2x, 4x X 4x, and 4x x OP crosses during embryogenesis and seed germination indicate that the progenies include an array of aneuploids. The occurrence of some of the aneuploids was previously unreported.

Antenatal screening for aneuploidy
Current Opinion in Obstetrics and Gynaecology, 1998There are several methods of antenatal screening for aneuploidy. Most are aimed at the identification of women at increased risk of Down syndrome, the most common abnormal karyotype conferring a significant risk of serious long-term morbidity. Traditional maternal-age-based screening has largely been replaced by programmes based on biochemical markers ...

Aneuploidy and tumorigenesis in Drosophila
Seminars in Cell & Developmental Biology, 2014Aneuploidy, described as an abnormal number of whole chromosomes or parts of them, has been observed in the majority of sporadic carcinomas, the most common type of cancer occurring in humans and derived from putative epithelial cells. However, the causal relationship between aneuploidy and tumorigenesis remains highly debated.

The Origin of Aneuploidy in Humans [PDF]
, 1985 Aneuploidy is the most common class of chromosome abnormality in humans and is considered by some to be the most important genetic hazard facing man (2). No less than 0.3% of all newborns are aneuploid (12), most with significant physical, intellectual, and behavioral abnormalities. Furthermore, these individuals are the least affected of all aneuploid

An extra chromosome slows yeast cell proliferation, suggesting that aneuploid human cells must overcome this effect during carcinogenesis.

Sex chromosome aneuploidies comprise a relatively common group of chromosome disorders characterized by the loss or gain of one or more sex chromosomes. We discuss five of the better-known sex aneuploidies: Turner syndrome (XO), Klinefelter syndrome (XXY), trisomy X (XXX), XYY, and XXYY.

The low reproductive potential of the human species is mainly caused by aneuploidies affecting embryo o fetal development. Although some of these aneuploidies may be paternally inherited or generated mitotically during preimplantation development, the vast majority of aneuploid karyotypes are generated at fertilization as an effect of meiotic errors ...
