Across TCGA pan-cancer cohorts, SLC12A9 mass-spec protein is linked to patient survival in 4 of 34 cancer types, making it a survival-associated SLC12A9 data layer compared with 26 for mass-spec protein and 11 for mutation status.
The strongest signal is observed in clear cell renal cell carcinoma (CCRCC), where higher SLC12A9 mass-spec protein is associated with worse disease-free survival. In most high-consensus cancer types, elevated SLC12A9 expression acts as an unfavorable survival marker, although some lineages such as LSCC show a favorable association.
CCRCC, LSCC, and LUAD are the cancer types where SLC12A9 mass-spec protein most reproducibly stratifies survival.
