Across TCGA pan-cancer cohorts, C1QTNF1 mass-spec protein is linked to patient survival in 1 of 34 cancer types, making it a survival-associated C1QTNF1 data layer compared with 25 for mass-spec protein and 8 for mutation status.
The strongest signal is observed in glioblastoma multiforme (GBM), where higher C1QTNF1 mass-spec protein is associated with worse overall survival. In most high-consensus cancer types, elevated C1QTNF1 expression acts as an unfavorable survival marker.
GBM are the cancer types where C1QTNF1 mass-spec protein most reproducibly stratifies survival.
