Whereas the mRNA levels of other H2As were not robustly different (Figure S2A–C), the mRNA levels of H2AFJ were significantly (p < 0.001) higher in GBM with wild-type IDH1, MGMT promoter unmethylation or non-CIMP, respectively, than in GBM with IDH1 mutations, MGMT promoter methylation or CIMP (Figure 1E). The gene discussed is IDH1; the disease is glioblastoma.
