Most cancer genomes are highly rearranged. Karyotyping first identified abnormal chromosome morphology as a common feature of cancers 1 – 5 (reviewed in ref. 6 , 7 ), and advances in DNA sequencing and analysis tools 8 , 9 subsequently led to the identification of complex chromosome rearrangements in cancer.
The technological advances summarized in Table 1 have enabled the detection of chromosomal rearrangements in cancer cells. Chromosomal rearrangements in cancer were first identified in the early 50s by karyotype analyses based on Giemsa (G-banding) or reverse Giemsa banding (R-banding). G-banding is a technique that produces a visible display ...
Cancer is clonal in origin and begins from mutations like these within a single cell that provide an environment for abnormal cell growth. As a tumor develops, the genome grows more unstable and ...

Abstract. Cancer genomes frequently harbor structural chromosomal rearrangements that disrupt the linear DNA sequence order and copy number. To date, diverse classes of structural variants have been identified across multiple cancer types. These aberrations span a wide spectrum of complexity, ranging from simple translocations to intricate ...

Recently, however, rearranged cancer fusion genes were discovered in more than half of prostate cancer cases 29 and in lung adenocarcinomas 30. Their late discovery probably reflects the difficulty of identifying them amidst the jumble of passenger rearrangements present in many cancer genomes and hints that there are many more rearranged cancer genes to be found in common cancers.
