Across TCGA pan-cancer cohorts, SNRPB mass-spec protein is linked to patient survival in 2 of 34 cancer types, making it a survival-associated SNRPB data layer compared with 28 for mass-spec protein and 5 for mutation status.
The strongest signal is observed in lung squamous cell carcinoma (LSCC), where higher SNRPB mass-spec protein is associated with worse disease-free survival. In most high-consensus cancer types, elevated SNRPB expression acts as an unfavorable survival marker.
LSCC and HNSC are the cancer types where SNRPB mass-spec protein most reproducibly stratifies survival.
