Across TCGA pan-cancer cohorts, WNT4 mass-spec protein is linked to patient survival in 3 of 34 cancer types, making it a survival-associated WNT4 data layer compared with 19 for mass-spec protein and 3 for mutation status.
The strongest signal is observed in lung squamous cell carcinoma (LSCC), where higher WNT4 mass-spec protein is associated with worse disease-free survival. In most high-consensus cancer types, elevated WNT4 expression acts as an unfavorable survival marker, although some lineages such as HNSC and PDAC show a favorable association.
LSCC, HNSC, and PDAC are the cancer types where WNT4 mass-spec protein most reproducibly stratifies survival.
