CACNA2D2 and neoplasm: Indeed, ssGSEA of our single‐cell data showed highly significant correlation between the NES of our generated EWSR1::WT1 and CACNA2D2 signatures (Figure 1G), regardless of tumor location, implying that CACNA2D2‐associated genes are also characteristic features of metastasized DSRCT cells (Supplementary Figure S3B).
