Figure 2. Pan-cancer prevalence of HER2 alterations (mutations and amplifications).
Panel A shows ERBB2 alterations seen in 6% of 85,575 patients with diverse cancers as per the cancer genomic data aggregated through AACR Project Genomics Evidence Neoplasia Information Exchange (GENIE) effort (AACR Genie v11.0-public). Only tumor types with ≥ 10 cases and at least 1% prevalence were included. Panel B shows the oncoprint in the same cohort and highlights the type of mutations seen in these patients with limited overlap of mutations and amplifications.
