Across TCGA pan-cancer cohorts, HERC4 mass-spec protein is linked to patient survival in 5 of 34 cancer types, making it a survival-associated HERC4 data layer compared with 26 for mass-spec protein and 3 for mutation status.
The strongest signal is observed in lung adenocarcinoma (LUAD), where higher HERC4 mass-spec protein is associated with worse disease-free survival. In most high-consensus cancer types, elevated HERC4 expression acts as an unfavorable survival marker, although some lineages such as UCEC and HNSC show a favorable association.
LUAD, UCEC, and LSCC are the cancer types where HERC4 mass-spec protein most reproducibly stratifies survival.
