Across TCGA pan-cancer cohorts, FXYD4 mass-spec protein is linked to patient survival in 1 of 34 cancer types, making it a survival-associated FXYD4 data layer compared with 16 for mass-spec protein and 3 for mutation status.
The strongest signal is observed in clear cell renal cell carcinoma (CCRCC), where higher FXYD4 mass-spec protein is associated with worse disease-free survival. In most high-consensus cancer types, elevated FXYD4 expression acts as an unfavorable survival marker.
CCRCC are the cancer types where FXYD4 mass-spec protein most reproducibly stratifies survival.
