Across TCGA pan-cancer cohorts, PHEX mass-spec protein is linked to patient survival in 1 of 34 cancer types, making it a survival-associated PHEX data layer compared with 22 for mass-spec protein and 8 for mutation status.
The strongest signal is observed in glioblastoma multiforme (GBM), where higher PHEX mass-spec protein is associated with worse disease-free survival. In most high-consensus cancer types, elevated PHEX expression acts as an unfavorable survival marker.
GBM are the cancer types where PHEX mass-spec protein most reproducibly stratifies survival.
