Across TCGA pan-cancer cohorts, SLC2A9 mass-spec protein is linked to patient survival in 3 of 34 cancer types, making it a survival-associated SLC2A9 data layer compared with 26 for mass-spec protein and 7 for mutation status.
The strongest signal is observed in clear cell renal cell carcinoma (CCRCC), where higher SLC2A9 mass-spec protein is associated with better overall survival. In most high-consensus cancer types, elevated SLC2A9 expression acts as an unfavorable survival marker, although some lineages such as CCRCC and LUAD show a favorable association.
CCRCC, LUAD, and HNSC are the cancer types where SLC2A9 mass-spec protein most reproducibly stratifies survival.
