Across TCGA pan-cancer cohorts, GALNT15 mass-spec protein is linked to patient survival in 1 of 34 cancer types, making it a survival-associated GALNT15 data layer compared with 23 for mass-spec protein and 4 for mutation status.
The strongest signal is observed in glioblastoma multiforme (GBM), where higher GALNT15 mass-spec protein is associated with worse disease-free survival. In most high-consensus cancer types, elevated GALNT15 expression acts as an unfavorable survival marker.
GBM are the cancer types where GALNT15 mass-spec protein most reproducibly stratifies survival.
