Across TCGA pan-cancer cohorts, HDAC2 mass-spec protein is linked to patient survival in 4 of 34 cancer types, making it a survival-associated HDAC2 data layer compared with 22 for mass-spec protein and 5 for mutation status.
The strongest signal is observed in head and neck squamous cell carcinoma (HNSC), where higher HDAC2 mass-spec protein is associated with worse overall survival. In most high-consensus cancer types, elevated HDAC2 expression acts as an unfavorable survival marker, although some lineages such as LSCC and PDAC show a favorable association.
HNSC, LSCC, and COAD are the cancer types where HDAC2 mass-spec protein most reproducibly stratifies survival.
