Across TCGA pan-cancer cohorts, BTC Mutation is linked to patient survival in 2 of 34 cancer types, making it a survival-associated BTC data layer compared with 24 for mass-spec protein and 1 for mass-spec protein.
The strongest signal is observed in liver hepatocellular carcinoma (LIHC), where higher BTC Mutation is associated with worse overall survival. In most high-consensus cancer types, elevated BTC expression acts as an unfavorable survival marker.
LIHC and CESC are the cancer types where BTC Mutation most reproducibly stratifies survival.
