Across TCGA pan-cancer cohorts, ZFY mass-spec protein is linked to patient survival in 1 of 34 cancer types, making it a survival-associated ZFY data layer compared with 25 for mass-spec protein and 2 for mutation status.
The strongest signal is observed in glioblastoma multiforme (GBM), where higher ZFY mass-spec protein is associated with better overall survival. In most high-consensus cancer types, elevated ZFY expression acts as an unfavorable survival marker, although some lineages such as GBM show a favorable association.
GBM are the cancer types where ZFY mass-spec protein most reproducibly stratifies survival.
