When we queried for EGFR expression in GBM subtypes on the GBM module, it could be observed that the mRNA and protein expression of EGFR is significantly higher in the classical subtype of GBM compared to all other subtypes (Fig. 4a shows mRNA expression boxplot, classical vs other subtypes p-value < 0.001). Here, EGFR is linked to glioblastoma.
