Across TCGA pan-cancer cohorts, ACTR3B Mutation is linked to patient survival in 4 of 34 cancer types, making it a survival-associated ACTR3B data layer compared with 22 for mass-spec protein and 6 for mass-spec protein.
The strongest signal is observed in liver hepatocellular carcinoma (LIHC), where higher ACTR3B Mutation is associated with worse disease-free survival. In most high-consensus cancer types, elevated ACTR3B expression acts as an unfavorable survival marker, although some lineages such as UCEC show a favorable association.
LIHC, ESCA, and LUAD are the cancer types where ACTR3B Mutation most reproducibly stratifies survival.
