Across TCGA pan-cancer cohorts, HMGB2 Mutation is linked to patient survival in 1 of 34 cancer types, making it a survival-associated HMGB2 data layer compared with 23 for mass-spec protein and 7 for mass-spec protein.
The strongest signal is observed in kidney chromophobe (KICH), where higher HMGB2 Mutation is associated with worse disease-free survival. In most high-consensus cancer types, elevated HMGB2 expression acts as an unfavorable survival marker.
KICH are the cancer types where HMGB2 Mutation most reproducibly stratifies survival.
