Across TCGA pan-cancer cohorts, H2BC1 mass-spec protein is linked to patient survival in 2 of 34 cancer types, making it a survival-associated H2BC1 data layer compared with 14 for mass-spec protein and 1 for mutation status.
The strongest signal is observed in pancreatic ductal adenocarcinoma (PDAC), where higher H2BC1 mass-spec protein is associated with worse disease-free survival. In most high-consensus cancer types, elevated H2BC1 expression acts as an unfavorable survival marker, although some lineages such as LUAD show a favorable association.
PDAC and LUAD are the cancer types where H2BC1 mass-spec protein most reproducibly stratifies survival.
