Across TCGA pan-cancer cohorts, FXYD5 mass-spec protein is linked to patient survival in 4 of 34 cancer types, making it a survival-associated FXYD5 data layer compared with 28 for mass-spec protein and 4 for mutation status.
The strongest signal is observed in head and neck squamous cell carcinoma (HNSC), where higher FXYD5 mass-spec protein is associated with better overall survival. In most high-consensus cancer types, elevated FXYD5 expression acts as an unfavorable survival marker, although some lineages such as HNSC and CCRCC show a favorable association.
HNSC, GBM, and PDAC are the cancer types where FXYD5 mass-spec protein most reproducibly stratifies survival.
