Across TCGA pan-cancer cohorts, SEC22B mass-spec protein is linked to patient survival in 6 of 34 cancer types, making it a survival-associated SEC22B data layer compared with 26 for mass-spec protein and 1 for mutation status.
The strongest signal is observed in clear cell renal cell carcinoma (CCRCC), where higher SEC22B mass-spec protein is associated with worse overall survival. In most high-consensus cancer types, elevated SEC22B expression acts as an unfavorable survival marker, although some lineages such as COAD and HNSC show a favorable association.
CCRCC, COAD, and HNSC are the cancer types where SEC22B mass-spec protein most reproducibly stratifies survival.
