DDAH1

Across TCGA pan-cancer cohorts, DDAH1 Mutation is linked to patient survival in 5 of 34 cancer types, making it a survival-associated DDAH1 data layer compared with 27 for mass-spec protein and 7 for mass-spec protein.

The strongest signal is observed in head and neck squamous cell carcinoma (HNSC), where higher DDAH1 Mutation is associated with worse disease-free survival. In most high-consensus cancer types, elevated DDAH1 expression acts as an unfavorable survival marker, although some lineages such as BLCA show a favorable association.

HNSC, LUAD, and UCEC are the cancer types where DDAH1 Mutation most reproducibly stratifies survival.

Mutation 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.
