Across TCGA pan-cancer cohorts, TNNI3K mass-spec protein is linked to patient survival in 6 of 34 cancer types, making it a survival-associated TNNI3K data layer compared with 20 for mass-spec protein and 8 for mutation status.
The strongest signal is observed in head and neck squamous cell carcinoma (HNSC), where higher TNNI3K mass-spec protein is associated with worse disease-free survival. In most high-consensus cancer types, elevated TNNI3K expression acts as an unfavorable survival marker, although some lineages such as LUAD and LSCC show a favorable association.
HNSC, LUAD, and LSCC are the cancer types where TNNI3K mass-spec protein most reproducibly stratifies survival.
