Noun[edit]

chromothripsis

  1. (genetics, pathology) A multiple of chromosomal rearrangements that is associated with some cancers.

      But for 2—3% of cancers, particularly bone cancer (up to 25%), recent evidence suggests that a single event of chromothripsis involving one or a few chromosomes leads to multiple gene rearrangements (in some cases tens to hundreds) that can disrupt tumor suppressor genes and/or produce oncogenic fusion genes.

      Another new phenomenon described by Stephens et al.[86] is called “chromothripsis”. Chromothripsis describes a massive genomic rearrangement in one or more chromosomes in a single catastrophic event during the cells' history,

      Some of the characteristics of chromothripsis are oscillating copy number changes, clustering of breakpoints, localized rearrangements involving one or a part of a chromosome, and complex rearrangements.
