The analysis of genes related to glioblastoma, ALT or TERT transcription: EGFR amplification; mutations in EGFR, TP53, PTEN, BRAF, PI3K, MYC, DAXX, SMARCA, and ATRX; CNV of CDKN2A/B; and RNA expression of the LncRNA TERC showed no differences in the distribution of these alterations depending on the TERTp mutation status (Table 3). Here, PIK3CG is linked to glioblastoma.
