Across TCGA pan-cancer cohorts, EIF1AX mass-spec protein is linked to patient survival in 6 of 34 cancer types, making it a survival-associated EIF1AX data layer compared with 28 for mass-spec protein and 6 for mutation status.
The strongest signal is observed in clear cell renal cell carcinoma (CCRCC), where higher EIF1AX mass-spec protein is associated with worse disease-free survival. In most high-consensus cancer types, elevated EIF1AX expression acts as an unfavorable survival marker, although some lineages such as LSCC and UCEC show a favorable association.
CCRCC, HNSC, and LSCC are the cancer types where EIF1AX mass-spec protein most reproducibly stratifies survival.
