Across TCGA pan-cancer cohorts, PRKAA1 mass-spec protein is linked to patient survival in 4 of 34 cancer types, making it a survival-associated PRKAA1 data layer compared with 22 for mass-spec protein and 5 for mutation status.
The strongest signal is observed in head and neck squamous cell carcinoma (HNSC), where higher PRKAA1 mass-spec protein is associated with worse disease-free survival. In most high-consensus cancer types, elevated PRKAA1 expression acts as an unfavorable survival marker.
HNSC, PDAC, and CCRCC are the cancer types where PRKAA1 mass-spec protein most reproducibly stratifies survival.
