Across TCGA pan-cancer cohorts, ARX mass-spec protein is linked to patient survival in 2 of 34 cancer types, making it a survival-associated ARX data layer compared with 24 for mass-spec protein and 4 for mutation status.
The strongest signal is observed in glioblastoma multiforme (GBM), where higher ARX mass-spec protein is associated with worse overall survival. In most high-consensus cancer types, elevated ARX expression acts as an unfavorable survival marker.
GBM and PDAC are the cancer types where ARX mass-spec protein most reproducibly stratifies survival.
