Across TCGA pan-cancer cohorts, IGHV3-21 Mutation is linked to patient survival in 3 of 34 cancer types, making it a survival-associated IGHV3-21 data layer compared with 24 for mass-spec protein and 5 for mass-spec protein.
The strongest signal is observed in colon adenocarcinoma (COAD), where higher IGHV3-21 Mutation is associated with worse disease-free survival. In most high-consensus cancer types, elevated IGHV3-21 expression acts as an unfavorable survival marker.
COAD, LIHC, and SKCM are the cancer types where IGHV3-21 Mutation most reproducibly stratifies survival.
