Across TCGA pan-cancer cohorts, BTF3L4 Mutation is linked to patient survival in 2 of 34 cancer types, making it a survival-associated BTF3L4 data layer compared with 21 for mass-spec protein and 5 for mass-spec protein.
The strongest signal is observed in sarcoma (SARC), where higher BTF3L4 Mutation is associated with worse disease-free survival. In most high-consensus cancer types, elevated BTF3L4 expression acts as an unfavorable survival marker.
SARC and ACC are the cancer types where BTF3L4 Mutation most reproducibly stratifies survival.
