Across TCGA pan-cancer cohorts, RRAGC mass-spec protein is linked to patient survival in 4 of 34 cancer types, making it a survival-associated RRAGC data layer compared with 23 for mass-spec protein and 1 for mutation status.
The strongest signal is observed in head and neck squamous cell carcinoma (HNSC), where higher RRAGC mass-spec protein is associated with better disease-free survival. In most high-consensus cancer types, elevated RRAGC expression acts as an unfavorable survival marker, although some lineages such as HNSC and PDAC show a favorable association.
HNSC, CCRCC, and GBM are the cancer types where RRAGC mass-spec protein most reproducibly stratifies survival.
