abstract = {Replication repair deficiency (RRD) leading to
hypermutation is an important driving mechanism of
high-grade glioma (HGG) occurring predominantly in the
context of germline mutations in RRD-associated genes.
Although HGG presents specific patterns of DNA methylation
corresponding to oncogenic mutations, this has not been well
studied in replication repair-deficient tumors. We analyzed
51 HGG arising in the background of gene mutations in RRD
utilizing either 450 k or 850 k methylation arrays. These
were compared with HGG not known to be from patients with
RRD. RRD HGG harboring secondary mutations in glioma genes
such as IDH1 and H3F3A displayed a methylation pattern
corresponding to these methylation subgroups. Strikingly,
RRD HGG lacking these known secondary mutations clustered
together with an incompletely described group of HGG
previously labeled 'Wild type-C' or 'Paediatric RTK 1'.
Independent analysis of two comparator HGG cohorts showed
that other RRD/hypermutant tumors clustered within these
subgroups, suggesting that undiagnosed RRD may be driving
some HGG clustering in this location. RRD HGG displayed a
unique CpG Island Demethylator Phenotype in contrast to the
CpG Island Methylator Phenotype described in other cancers.
Hypomethylation was enriched at gene promoters with
prominent demethylation in genes and pathways critical to
cellular survival including cell cycle, gene expression,
cellular metabolism, and organization. These data suggest
that methylation arrays may provide diagnostic information
for the detection of RRD HGG. Furthermore, our findings
highlight the unique natural selection pressures in these
highly dysregulated, hypermutant cancers and provide the
novel impact of hypermutation and RRD on the cancer
epigenome.},
