Across TCGA pan-cancer cohorts, PHF5A mass-spec protein is linked to patient survival in 5 of 34 cancer types, making it a survival-associated PHF5A data layer compared with 27 for mass-spec protein and 3 for mutation status.
The strongest signal is observed in head and neck squamous cell carcinoma (HNSC), where higher PHF5A mass-spec protein is associated with worse overall survival. In most high-consensus cancer types, elevated PHF5A expression acts as an unfavorable survival marker, although some lineages such as COAD and LSCC show a favorable association.
HNSC, COAD, and LSCC are the cancer types where PHF5A mass-spec protein most reproducibly stratifies survival.
