Using a public NB dataset from the R2 Genomics Analysis and Visualization Platform containing 649 samples, we found that MYCN expression does weakly negatively correlate with CD8A gene expression levels when MYCN is WT (Fig. 1D), while ARID1A loss shows a highly significant correlation with a decrease in CD8A levels when MYCN is WT. Here, CD8A is linked to neuroblastoma.
