Across TCGA pan-cancer cohorts, TTC39C mass-spec protein is linked to patient survival in 5 of 34 cancer types, making it a survival-associated TTC39C data layer compared with 26 for mass-spec protein and 7 for mutation status.
The strongest signal is observed in clear cell renal cell carcinoma (CCRCC), where higher TTC39C mass-spec protein is associated with worse disease-free survival. In most high-consensus cancer types, elevated TTC39C expression acts as an unfavorable survival marker, although some lineages such as PDAC and LSCC show a favorable association.
CCRCC, PDAC, and LSCC are the cancer types where TTC39C mass-spec protein most reproducibly stratifies survival.
