This is in clear contrast to the genomic profile of the tumor seen in Figure 2B where the 1p/19q deletion is absent whereas a strong amplification of chromosome 7 (with a high peak corresponding to the epidermal growth factor receptor), deletion of chromosome 10 and homozygous deletion on chromosome 9 are seen; all highly characteristic of a glioblastoma. Here, EGFR is linked to neoplasm.
