Across TCGA pan-cancer cohorts, HECTD4 mass-spec protein is linked to patient survival in 6 of 34 cancer types, making it a survival-associated HECTD4 data layer compared with 22 for mass-spec protein and 12 for mutation status.
The strongest signal is observed in pancreatic ductal adenocarcinoma (PDAC), where higher HECTD4 mass-spec protein is associated with worse overall survival. In most high-consensus cancer types, elevated HECTD4 expression acts as an unfavorable survival marker, although some lineages such as LSCC and GBM show a favorable association.
PDAC, LSCC, and LUAD are the cancer types where HECTD4 mass-spec protein most reproducibly stratifies survival.
