Across TCGA pan-cancer cohorts, ST6GALNAC4 mass-spec protein is linked to patient survival in 2 of 34 cancer types, making it a survival-associated ST6GALNAC4 data layer compared with 27 for mass-spec protein and 3 for mutation status.
The strongest signal is observed in lung adenocarcinoma (LUAD), where higher ST6GALNAC4 mass-spec protein is associated with better overall survival. In most high-consensus cancer types, elevated ST6GALNAC4 expression acts as an unfavorable survival marker, although some lineages such as LUAD show a favorable association.
LUAD and LSCC are the cancer types where ST6GALNAC4 mass-spec protein most reproducibly stratifies survival.
