As shown in Figures S1A, B, the EUH subset includes (i) MYC-driven neuroblastoma expressing high MYC and/or MYCN protein (8), (ii) Neuroblastoma with TERT overexpression due to genomic rearrangements (9–11), and (iii) Neuroblastoma of the ALT group due to ATRX loss (12, 13). This evidence concerns the gene ATRX and neuroblastoma.
