Gene expression levels measured relative to the adjacent normal cortex sample revealed numerous oncogenic driver genes with >2-fold higher expression in the tumour and clone samples, including genes encoding AURKA/B, CDK4/6, FGFR1, AKT1/2, MTOR, MET, PIK3C2A, WNT5A, SFRP4, and MYC (Figure 5B and Figure S3C). Here, SFRP4 is linked to neoplasm.
