To select genes relevant to primary NB tumors, we overlapped the differentially expressed genes in SHEP cells (absolute fold change ≥ 1.25; FDR < 0.1) with CHAF1A‐correlated genes (FDR < 0.1) in two NB patient cohorts (cohort 1: TARGET, n = 249; cohort 2: GSE45547, n = 648). Here, CHAF1A is linked to neuroblastoma.
