Across TCGA pan-cancer cohorts, ERCC4 mass-spec protein is linked to patient survival in 5 of 34 cancer types, making it a survival-associated ERCC4 data layer compared with 26 for mass-spec protein and 4 for mutation status.
The strongest signal is observed in glioblastoma multiforme (GBM), where higher ERCC4 mass-spec protein is associated with better overall survival. In most high-consensus cancer types, elevated ERCC4 expression acts as an unfavorable survival marker, although some lineages such as GBM and HNSC show a favorable association.
GBM, HNSC, and PDAC are the cancer types where ERCC4 mass-spec protein most reproducibly stratifies survival.
