Across TCGA pan-cancer cohorts, ARL6 mass-spec protein is linked to patient survival in 5 of 34 cancer types, making it a survival-associated ARL6 data layer compared with 24 for mass-spec protein and 6 for mutation status.
The strongest signal is observed in head and neck squamous cell carcinoma (HNSC), where higher ARL6 mass-spec protein is associated with worse disease-free survival. In most high-consensus cancer types, elevated ARL6 expression acts as an unfavorable survival marker, although some lineages such as PDAC and CCRCC show a favorable association.
HNSC, PDAC, and LSCC are the cancer types where ARL6 mass-spec protein most reproducibly stratifies survival.
