Across TCGA pan-cancer cohorts, H2BC9 Mutation is linked to patient survival in 2 of 34 cancer types, making it a survival-associated H2BC9 data layer compared with 23 for mass-spec protein.
The strongest signal is observed in ovarian serous cystadenocarcinoma (OV), where higher H2BC9 Mutation is associated with worse disease-free survival. In most high-consensus cancer types, elevated H2BC9 expression acts as an unfavorable survival marker.
OV and ESCA are the cancer types where H2BC9 Mutation most reproducibly stratifies survival.
