In detail, the EGFR oncogene whose amplification defines a subset of GBM [3], [38], [39], was the only gene coded in the 7p11.2 amplicon for which a significantly high correlation between DNA CN values and gene expression levels was detected; although this amplicon contained other bystander genes that may be co-amplified with EGFR (e.g. LANCL2 and GASP) due to their genomic proximity [14], amplification of all such genes showed limited impact on gene expression levels. This evidence concerns the gene LANCL2 and glioblastoma.
