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