Across TCGA pan-cancer cohorts, SLC22A2 mass-spec protein is linked to patient survival in 1 of 34 cancer types, making it a survival-associated SLC22A2 data layer compared with 20 for mass-spec protein and 5 for mutation status.
The strongest signal is observed in clear cell renal cell carcinoma (CCRCC), where higher SLC22A2 mass-spec protein is associated with worse disease-free survival. In most high-consensus cancer types, elevated SLC22A2 expression acts as an unfavorable survival marker.
CCRCC are the cancer types where SLC22A2 mass-spec protein most reproducibly stratifies survival.
