First, gene-level differential analysis of the stromal component of KIRC against the other eight tumor types revealed 941 differentially expressed (DE) genes (q< 0.05, BH adjusted), including the Mcf2l, Exoc3l2, Olfr558, and Chrm2 (Table S4) listed as the top-ranked genes. Here, EXOC3L2 is linked to neoplasm.
