Across TCGA pan-cancer cohorts, BCL2L1 mass-spec protein is linked to patient survival in 4 of 34 cancer types, making it a survival-associated BCL2L1 data layer compared with 23 for mass-spec protein and 2 for mutation status.
The strongest signal is observed in clear cell renal cell carcinoma (CCRCC), where higher BCL2L1 mass-spec protein is associated with worse disease-free survival. In most high-consensus cancer types, elevated BCL2L1 expression acts as an unfavorable survival marker, although some lineages such as HNSC show a favorable association.
CCRCC, HNSC, and PDAC are the cancer types where BCL2L1 mass-spec protein most reproducibly stratifies survival.
