Across TCGA pan-cancer cohorts, SLC6A6 mass-spec protein is linked to patient survival in 4 of 34 cancer types, making it a survival-associated SLC6A6 data layer compared with 24 for mass-spec protein and 7 for mutation status.
The strongest signal is observed in clear cell renal cell carcinoma (CCRCC), where higher SLC6A6 mass-spec protein is associated with worse disease-free survival. In most high-consensus cancer types, elevated SLC6A6 expression acts as an unfavorable survival marker.
CCRCC, PDAC, and LSCC are the cancer types where SLC6A6 mass-spec protein most reproducibly stratifies survival.
