Across TCGA pan-cancer cohorts, TTC21A RNA is linked to patient survival in 27 of 34 cancer types, making it the most broadly survival-associated TTC21A data layer compared with 11 for mutation status and 1 for mass-spec protein.
The strongest signal is observed in head and neck squamous cell carcinoma (HNSC), where higher TTC21A RNA is associated with better overall survival. In most high-consensus cancer types, elevated TTC21A expression acts as an unfavorable survival marker, although some lineages such as HNSC and BRCA show a favorable association.
HNSC, KIRC, and BRCA are the cancer types where TTC21A RNA most reproducibly stratifies survival.
RNA survival associations by lineage
Ranked by sampling consensus. AUC1 and AUC2 indicate survival in the high- and low-expression groups, respectively; the lower AUC marks the poorer-surviving group. p-values are from the log-rank test.
