Across TCGA pan-cancer cohorts, SCML4 mass-spec protein is linked to patient survival in 1 of 34 cancer types, making it a survival-associated SCML4 data layer compared with 26 for mass-spec protein and 3 for mutation status.
The strongest signal is observed in lung squamous cell carcinoma (LSCC), where higher SCML4 mass-spec protein is associated with worse overall survival. In most high-consensus cancer types, elevated SCML4 expression acts as an unfavorable survival marker.
LSCC are the cancer types where SCML4 mass-spec protein most reproducibly stratifies survival.
