Across TCGA pan-cancer cohorts, HBS1L mass-spec protein is linked to patient survival in 4 of 34 cancer types, making it a survival-associated HBS1L data layer compared with 28 for mass-spec protein and 4 for mutation status.
The strongest signal is observed in clear cell renal cell carcinoma (CCRCC), where higher HBS1L mass-spec protein is associated with worse disease-free survival. In most high-consensus cancer types, elevated HBS1L expression acts as an unfavorable survival marker, although some lineages such as LSCC and GBM show a favorable association.
CCRCC, PDAC, and LSCC are the cancer types where HBS1L mass-spec protein most reproducibly stratifies survival.
