Supplementary Figure 1: MYCN subgroup tumors show recurrent structural variants involving high-level amplification and rearrangement of MYCN, ID2 and KIDINS220 on chromosome 2p.

SNP6.0 copy number profiles of chromosome 2p focal, high-level amplifications in (a) DIPG38, (b) DIPG49, (c) DIPG01 and (d) DIPG29. These amplifications always involve the genes MYCN, ID2 and KIDINS220. Circos plots of structural variants in (e) DIPG01 and (f) DIPG29 as determined from WGS data.
