Chromothripsis and beyond: rapid genome evolution from complex chromosomal rearrangements

TLDR
The impact of massive chromosomal change for the development of diseases such as cancer and for evolution more generally is considered and current models for underlying mechanisms are summarized.
Abstract
Recent genome sequencing studies have identified several classes of complex genomic rearrangements that appear to be derived from a single catastrophic event. These discoveries identify ways that genomes can be altered in single large jumps rather than by many incremental steps. Here we compare and contrast these phenomena and examine the evidence that they arise "all at once." We consider the impact of massive chromosomal change for the development of diseases such as cancer and for evolution more generally. Finally, we summarize current models for underlying mechanisms and discuss strategies for testing these models.

Patterns of Somatic Mutation in Human Cancer Genomes

TL;DR: In this paper, the coding exons of the family of 518 protein kinases were sequenced in 210 cancers of diverse histological types to explore the nature of the information that will be derived from cancer genome sequencing.

Spatial and temporal diversity in genomic instability processes defines lung cancer evolution

TL;DR: 25 spatially distinct regions from seven operable NSCLCs were sequenced and found evidence of branched evolution, with driver mutations arising before and after subclonal diversification, and pronounced intratumor heterogeneity in copy number alterations, translocations, and mutations associated with APOBEC cytidine deaminase activity.

Chromothripsis from DNA damage in micronuclei

TL;DR: It is demonstrated that micronucleus formation can indeed generate a spectrum of genomic rearrangements, some of which recapitulate all known features of chromothripsis.

DNA double-strand break repair-pathway choice in somatic mammalian cells.

TL;DR: This Review considers DSB repair-pathway choice in somatic mammalian cells as a series of ‘decision trees’, and explores how defective pathway choice can lead to genomic instability.

Spatial genome organization in the formation of chromosomal translocations

TL;DR: The emerging principles of spatial genome organization are reviewed and the implications of non-random spatial genome organizations for the genesis and specificity of cancerous chromosomal translocations are discussed.

Chromothripsis is a common mechanism driving genomic rearrangements in primary and metastatic colorectal cancer

TL;DR: It is concluded that chromothripsis is a prevalent mechanism driving structural rearrangements in colorectal cancer and a complex interplay between point mutations, simple copy number changes and chromothRIpsis events drive coloreCTal tumor development and metastasis.
