SAMD4B

RNA & survival
SurvivalRNAKaplan–Meier · TCGA cohorts

Across TCGA pan-cancer cohorts, SAMD4B RNA is linked to patient survival in 29 of 34 cancer types, making it the most broadly survival-associated SAMD4B data layer compared with 6 for mutation status and 3 for mass-spec protein.

The strongest signal is observed in adrenocortical carcinoma (ACC), where higher SAMD4B RNA is associated with worse disease-free survival. In most high-consensus cancer types, elevated SAMD4B expression acts as an unfavorable survival marker, although some lineages such as SCLC and UCS show a favorable association.

ACC, SCLC, and BLCA are the cancer types where SAMD4B 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.
