Across TCGA pan-cancer cohorts, BTF3L4 mass-spec protein is linked to patient survival in 5 of 34 cancer types, making it a survival-associated BTF3L4 data layer compared with 21 for mass-spec protein and 2 for mutation status.
The strongest signal is observed in clear cell renal cell carcinoma (CCRCC), where higher BTF3L4 mass-spec protein is associated with worse disease-free survival. In most high-consensus cancer types, elevated BTF3L4 expression acts as an unfavorable survival marker, although some lineages such as LUAD and LSCC show a favorable association.
CCRCC, PDAC, and OV are the cancer types where BTF3L4 mass-spec protein most reproducibly stratifies survival.
