Across TCGA pan-cancer cohorts, APBA1 mass-spec protein is linked to patient survival in 5 of 34 cancer types, making it a survival-associated APBA1 data layer compared with 20 for mass-spec protein and 5 for mutation status.
The strongest signal is observed in lung squamous cell carcinoma (LSCC), where higher APBA1 mass-spec protein is associated with worse overall survival. In most high-consensus cancer types, elevated APBA1 expression acts as an unfavorable survival marker, although some lineages such as LUAD and HNSC show a favorable association.
LSCC, UCEC, and LUAD are the cancer types where APBA1 mass-spec protein most reproducibly stratifies survival.
