MYCN and neuroblastoma: This variant was found to be located in open chromatin regions identified in 29 ATAC‐seq and 5 H3K27ac ChIP‐seq experiments in various neuroblastoma cell lines (Figure 1B, Table S1, and Figure S1, Supporting Information), but also showed the highest enrichment of TF binding sites, including MYCN, LMO1, GATA3, HAND2, ISL1, PHOX2B, and TBX2 (Table S1 and Figure S1, Supporting Information).
