Across TCGA pan-cancer cohorts, GRAMD1C mass-spec protein is linked to patient survival in 3 of 34 cancer types, making it a survival-associated GRAMD1C data layer compared with 22 for mass-spec protein and 5 for mutation status.
The strongest signal is observed in clear cell renal cell carcinoma (CCRCC), where higher GRAMD1C mass-spec protein is associated with better overall survival. In most high-consensus cancer types, elevated GRAMD1C expression acts as an unfavorable survival marker, although some lineages such as CCRCC and GBM show a favorable association.
CCRCC, GBM, and LUAD are the cancer types where GRAMD1C mass-spec protein most reproducibly stratifies survival.
