Fig. 4: Somatic mutations, clonal composition, and copy number variation profiles of primary PBTs and matched PDTs.

Heatmap depicting somatic alterations and cancer cell fractions in primary tumors of pediatric low-grade gliomas (LGGs), pediatric high-grade gliomas (HGGs), an ependymoma (EPM), and a medulloblastoma (MB_02) and their matched PDTs. HGG_04 and BCOR_02 molecular profile was not determined using the OCCRA panel but through PCR and Sanger sequencing analysis (Fig. S1, S2 and Table S3). Cases are shown in columns, and genes are in rows. Mutations and cancer cell fractions are color-coded according to the legend.
