Across TCGA pan-cancer cohorts, STX12 mass-spec protein is linked to patient survival in 4 of 34 cancer types, making it a survival-associated STX12 data layer compared with 23 for mass-spec protein and 2 for mutation status.
The strongest signal is observed in head and neck squamous cell carcinoma (HNSC), where higher STX12 mass-spec protein is associated with better overall survival. In most high-consensus cancer types, elevated STX12 expression acts as an unfavorable survival marker, although some lineages such as HNSC and UCEC show a favorable association.
HNSC, UCEC, and LSCC are the cancer types where STX12 mass-spec protein most reproducibly stratifies survival.
