RAB3A

Across TCGA pan-cancer cohorts, RAB3A Mutation is linked to patient survival in 3 of 34 cancer types, making it a survival-associated RAB3A data layer compared with 23 for mass-spec protein and 6 for mass-spec protein.

The strongest signal is observed in skin cutaneous melanoma (SKCM), where higher RAB3A Mutation is associated with worse disease-free survival. In most high-consensus cancer types, elevated RAB3A expression acts as an unfavorable survival marker.

SKCM, PRAD, and UCEC are the cancer types where RAB3A 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.
