WebChromothripsis is a mitotic catastrophe that arises from multiple double strand breaks and incorrect re-joining of one or a few chromosomes. We report on incidence, distribution, and features of chromothriptic events in T-cell acute lymphoblastic leukemias (T-ALL). WebMar 19, 2014 · Background: Chromothripsis, a newly discovered type of complex genomic rearrangement, has been implicated in the evolution of several types of cancers.

WebApr 1, 2024 · Chromothripsis is defined as the mechanism by which tens to hundreds of locally clustered DNA rearrangements are formed, typically in one or a few chromosomes, caused by a single event sometimes accompanied by double-minute chromosomes [ 1 ].
WebLongitudinal analysis of chromothriptic patterns in 24 matched tumour pairs reveals novel insights in the clonal evolution ... (Show More) Chromothripsis is a recently identified mutational phenomenon, by which a presumably single catastrophic event generates extensive genomic rearrangements of one or a few chromosome(s).
