Across TCGA pan-cancer cohorts, STX1A Mutation is linked to patient survival in 4 of 34 cancer types, making it a survival-associated STX1A data layer compared with 25 for mass-spec protein and 3 for mass-spec protein.
The strongest signal is observed in liver hepatocellular carcinoma (LIHC), where higher STX1A Mutation is associated with worse overall survival. In most high-consensus cancer types, elevated STX1A expression acts as an unfavorable survival marker.
LIHC, PRAD, and UCEC are the cancer types where STX1A Mutation most reproducibly stratifies survival.
