Across TCGA pan-cancer cohorts, HMG20A mass-spec protein is linked to patient survival in 6 of 34 cancer types, making it a survival-associated HMG20A data layer compared with 23 for mass-spec protein and 4 for mutation status.
The strongest signal is observed in head and neck squamous cell carcinoma (HNSC), where higher HMG20A mass-spec protein is associated with worse disease-free survival. In most high-consensus cancer types, elevated HMG20A expression acts as an unfavorable survival marker, although some lineages such as CCRCC and GBM show a favorable association.
HNSC, CCRCC, and GBM are the cancer types where HMG20A mass-spec protein most reproducibly stratifies survival.
