Genome Sequencing of Pediatric Medulloblastoma Links Catastrophic DNA Rearrangements with TP53 Mutations

Abstract: SUMMARY Genomic rearrangements are thought to occur progressively during tumor development. Recent findings, however, suggest an alternative mechanism, involving massive chromosome rearrangements in a one-step catastrophic event termed chromothripsis. We report the whole-genome sequencing-based analysis of a Sonic-Hedgehog medulloblastoma (SHH-MB) brain tumor from a patient with a germline TP53 mutation (Li-Fraumeni syndrome), uncovering massive, complex chromosome rearrangements. Integrating TP53 status with … Show more

“…18,37 To infer chromothripsis with array-based copy number profiling data, various criteria have been applied, the central common part of which is to identify oscillating copy number states on a single chromosome. [38][39][40][41] On the basis of copy number profiling, chromothripsis was present in an estimated 1-3% of human cancers. 18,42 By contrast, 19% (3/16) of cases (and 38% of the 'S' group) in the current series presented copy number profiles suggesting chromothripsis, a phenomenon unprecedented in adenosarcoma.…”

“…It has been implied that chromothripsis causes amplifications in the form of double minutes. 18,38 The chromosome painting analysis suggested that amplification of chromosome 12 in cases S1 and S6 might have resulted from chromothripsis through double minute formation, whereas amplifications in chromosomes without chromothripsis might have been caused by other mechanisms. 44 Indeed, the mixed chromosome 12 painting and MDM2 FISH in Figure 5d might give a hint of homogeneously staining region as the mechanism of amplification.…”

“…For this test, we analyzed whole-genome sequence data from another mantle cell lymphoma sample (M003) and a sample from a pediatric form of a medulloblastoma (MB1), both known to present complex landscapes of chromosomal rearrangements 12,13 . Because these representative examples corresponded to a hematological and a solid tumor, each sequenced in a different sequencing facility, this analysis also measured SMUFIN's consistency across different types of data.…”
