GBM methylCIBERSORT analysis of a cohort of 435 glioma samples we previously profiled (Capper et al., 2018) further revealed prominent CD14 monocytic and neutrophilic DNA methylation and low CD8+ T-cell methylation signatures in MES patients, and low CD14 monocytic and neutrophilic DNA methylation and high CD8+ T-cell methylation in PN (RTK_I) patients (Figure 1C). Here, CD8A is linked to Meckel syndrome, type 1.
