CACNA2D2 and desmoplastic small round cell tumor: Moreover, both bulk‐ and sc‐derived CACNA2D2 signatures precisely distinguished DSRCT cell clusters from non‐tumor cells in single‐cell RNA‐sequencing (scRNA‐seq) data from four DSRCT patients (n = 11 samples) [9] (Figure 1I, Supplementary Figure S3E).
