Across TCGA pan-cancer cohorts, FUT3 Mutation is linked to patient survival in 5 of 34 cancer types, making it a survival-associated FUT3 data layer compared with 20 for mass-spec protein and 2 for mass-spec protein.
The strongest signal is observed in sarcoma (SARC), where higher FUT3 Mutation is associated with worse overall survival. In most high-consensus cancer types, elevated FUT3 expression acts as an unfavorable survival marker, although some lineages such as UCEC and SKCM show a favorable association.
SARC, UCEC, and STAD are the cancer types where FUT3 Mutation most reproducibly stratifies survival.
