Table 2 Contingency table of samples used for methylation profiling

From: Transcriptomic and epigenetic profiling of ‘diffuse midline gliomas, H3 K27M-mutant’ discriminate two subgroups based on the type of histone H3 mutated and not supratentorial or infratentorial location

Tumor location Histone H3 mutational status PDGFRA subgroup MYCN subgroup Total number of samples
H3.3-G34R H3.1-K27M H3.3-K27M H3.2-K27M
Cortex 10 0 0 0 10 10 30
Pons 0 12 19 1 0 0 32
Thalamic midline 0 1 17 0 0 0 18
  1. Eighty high grade gliomas were analyzed by 450 k and EPIC Illumina bead arrays. Tumor location and histone H3 mutations or PDGFRA and MYCN molecular subgroups were considered for sample stratification
