Across TCGA pan-cancer cohorts, SLC6A15 mass-spec protein is linked to patient survival in 1 of 34 cancer types, making it a survival-associated SLC6A15 data layer compared with 27 for mass-spec protein and 8 for mutation status.
The strongest signal is observed in glioblastoma multiforme (GBM), where higher SLC6A15 mass-spec protein is associated with worse disease-free survival. In most high-consensus cancer types, elevated SLC6A15 expression acts as an unfavorable survival marker.
GBM are the cancer types where SLC6A15 mass-spec protein most reproducibly stratifies survival.
