Aneuploidy has been recognized as a common characteristic of cancer cells for >100 years. Aneuploidy frequently results from errors of the mitotic checkpoint, the major cell cycle control mechanism that acts to prevent chromosome missegregation.
In contrast to normal cells, aneuploidy — alterations in the number of chromosomes — is consistently observed in virtually all cancers. A growing body of evidence suggests that aneuploidy is often caused by a particular type of genetic instability, called chromosomal instability, which may reflect defects in mitotic segregation in cancer cells.
Aneuploidy was anti-correlated with expression of immune signaling genes Aneuploidy. Aneuploidy refers to copy number changes that encompass entire chromosome arms or whole chromosomes. It is the most prevalent genetic aberration in human cancer. Approximately 90% of solid tumours and 75% of blood cancers are aneuploid in nature. As cancer cells are mostly aneuploid and normal cells are almost always euploid in cancer is less clearly understood. Aneuploidy refers to an aberrant chromosome number that deviates from a multiple of the haploid set and was first associated with cancer more than a century ago [1]. As cancer cells are rife with defects in many cellular processes, some have considered aneuploidy to be a benign side effect that accom Mosaic variegated aneuploidy (MVA) is a rare disorder characterized by high levels of mosaic aneuploidy and a significantly increased risk of cancer [15, 16].

Numeric aberrations in chromosomes, referred to as aneuploidy, is commonly observed in human cancer. Whether aneuploidy is a cause or consequence of cancer has long been debated. Three lines of evidence now make a compelling case for aneuploidy being a discrete chromosome mutation event that contributes to malignant transformation and progression process. Aneuploidy is a characteristic of cancer, with greater than 90% of all solid tumors in humans carrying an aberrant karyotype.

There have been attitude changes towards the study of aneuploidy as well. Aneuploidy is the presence of an abnormal number of chromosomes in a cell, for example a human cell having 45 or 47 chromosomes instead of the usual 46. It does not include a difference of one or more complete sets of chromosomes.

As aneuploidy is a hallmark of cancer cells that discriminates healthy cells from cancer cells, such mechanisms make promising targets for cancer therapy, which will be discussed in the context of the consequences of aneuploidy. Figure 2 shows an overview of …
A growing body of evidence suggests that aneuploidy is often caused by a particular type of genetic instability, called chromosomal instability, which may reflect defects in mitotic segregation in cancer cells. Aneuploidy is a very rare and tissue-specific event in normal conditions, occurring in a low number of brain and liver cells.
