Across TCGA pan-cancer cohorts, CD55 Mutation is linked to patient survival in 2 of 34 cancer types, making it a survival-associated CD55 data layer compared with 23 for mass-spec protein and 5 for mass-spec protein.

The strongest signal is observed in lung squamous cell carcinoma (LUSC), where higher CD55 Mutation is associated with worse overall survival. In most high-consensus cancer types, elevated CD55 expression acts as an unfavorable survival marker.

LUSC and BRCA are the cancer types where CD55 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.
