Genes, Chromosomes & Cancer is a monthly peer-reviewed academic journal published by Wiley-Blackwell. According to the Journal Citation Reports , the journal has a 2014 impact factor of 4.041. [ 1 ]
The Atlas of Genetics and Cytogenetics in Oncology and Haematology, created in 1997 by Jean-Loup Huret (with bioinformatics by Philippe Dessen) is a collection of resources on genes, chromosomes anomalies, leukemias, solid tumours, and cancer-prone diseases.
HeLa cells are rapidly dividing cancer cells, and the number of chromosomes varies during cancer formation and cell culture. The current estimate (excluding very tiny fragments) is a "hypertriploid chromosome number (3n+)", which means 76 to 80 total chromosomes (rather than the normal diploid number of 46) with 22–25 clonally abnormal ...
A cancer syndrome or family cancer syndrome is a genetic disorder in which inherited genetic mutations in one or more genes predisposes the affected individuals to the development of cancers and may also cause the early onset of these cancers. Although cancer syndromes exhibit an increased risk of cancer, the risk varies.
The first fusion gene [1] was described in cancer cells in the early 1980s. The finding was based on the discovery in 1960 by Peter Nowell and David Hungerford in Philadelphia of a small abnormal marker chromosome in patients with chronic myeloid leukemia—the first consistent chromosome abnormality detected in a human malignancy, later designated the Philadelphia chromosome.

In UPD, a person receives two copies of a chromosome, or part of a chromosome, from one parent and no copies from the other parent due to errors in meiosis I or meiosis II. This acquired homozygosity could lead to development of cancer if the individual inherited a non-functional allele of a tumor suppressor gene.
Visit Gene Alterations and Cancer to learn more about epigenetic alterations. Chromosomal rearrangement: Every living creature has chromosomes, which are substantial strands of DNA that contain the genes for a cell. A chromosome's DNA sequence may alter each time a cell divides.
An extensive cancer database search found that about 1.4% of all cases are positive for DMs, and out of cancer types, neuroblastoma has the highest frequency of DMs at 31.7%. [10] The amplification of specific genes that support the growth of tumor cells, such as oncogenes or drug-resistant genes, is critical to the cell adoption of malignancy ...
