Across TCGA pan-cancer cohorts, APOL5 mass-spec protein is linked to patient survival in 3 of 34 cancer types, making it a survival-associated APOL5 data layer compared with 29 for mass-spec protein and 5 for mutation status.
The strongest signal is observed in lung adenocarcinoma (LUAD), where higher APOL5 mass-spec protein is associated with worse disease-free survival. In most high-consensus cancer types, elevated APOL5 expression acts as an unfavorable survival marker.
LUAD, PDAC, and GBM are the cancer types where APOL5 mass-spec protein most reproducibly stratifies survival.
