Across TCGA pan-cancer cohorts, FAM221B Mutation is linked to patient survival in 1 of 34 cancer types, making it a survival-associated FAM221B data layer compared with 20 for mass-spec protein.

The strongest signal is observed in uterine corpus endometrial carcinoma (UCEC), where higher FAM221B Mutation is associated with worse overall survival. In most high-consensus cancer types, elevated FAM221B expression acts as an unfavorable survival marker.

UCEC are the cancer types where FAM221B 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.
