Chromothripsis | Chromoplexy | Chromoanasynthesis | |
Origin | ‘chromo’ for chromosomes and ‘thripsis’ for shattering into pieces | ‘chromo’ for chromosomes and ‘pleko’ for braid or weave together | ‘chromo’ for chromosomes and ‘anasynthesis’ for reconstitution |
Definition | A single event of local chromosome shattering that produces tens to hundreds of fragments, followed by random restitching driven by NHEJ | Co-occurrence of multiple inter- and intra-chromosomal translocations and (to a lesser extent) deletions, frequently involving five or more chromosomes | A replication-based process with local rearrangements and altered gene copy numbers due to serial fork stalling or template switching, or microhomology-mediated break-induced replication |
