Across TCGA pan-cancer cohorts, SYT4 mass-spec protein is linked to patient survival in 1 of 34 cancer types, making it a survival-associated SYT4 data layer compared with 20 for mass-spec protein and 6 for mutation status.
The strongest signal is observed in glioblastoma multiforme (GBM), where higher SYT4 mass-spec protein is associated with worse overall survival. In most high-consensus cancer types, elevated SYT4 expression acts as an unfavorable survival marker.
GBM are the cancer types where SYT4 mass-spec protein most reproducibly stratifies survival.
