Across TCGA pan-cancer cohorts, DDAH2 Mutation is linked to patient survival in 4 of 34 cancer types, making it a survival-associated DDAH2 data layer compared with 23 for mass-spec protein and 6 for mass-spec protein.

The strongest signal is observed in small cell lung cancer (SCLC), where higher DDAH2 Mutation is associated with worse overall survival. In most high-consensus cancer types, elevated DDAH2 expression acts as an unfavorable survival marker, although some lineages such as UCEC show a favorable association.

SCLC, SKCM, and KIRC are the cancer types where DDAH2 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.
