Gene transcripts encoding ion channels and receptors with high neural specificity included the calcium signaling modulator SIGMAR1 and cannabinoid receptor CNR1. Both had considerably lower patient specificity than oncogenic RTKs EGFR and PDGFRA, despite similar detection levels (Fig. 3c and Supplementary Table 3), highlighting consistent pan-patient expression of NAD targets in glioblastoma. This evidence concerns the gene EGFR and glioblastoma.
