Across TCGA pan-cancer cohorts, SAMD4A RNA differs between tumor and matched normal tissue in 13 of 18 cancer types tested, making tumor–normal expression one of SAMD4A’s most consistent transcriptional readouts.
The strongest signal is observed in bladder urothelial carcinoma (BLCA), where SAMD4A RNA is repressed in tumor relative to normal tissue. In most cancer types SAMD4A is over-expressed in tumor, although a few such as BLCA and LUAD show the opposite, repressed pattern.
BLCA, THCA, and LUAD are the cancer types where SAMD4A tumor–normal differential expression is most reproducible.
RNA tumor vs normal associations by lineage
Ranked by sampling consensus. Fold-change is the tumor-versus-normal difference in SAMD4A RNA (log2); positive values indicate higher expression in tumor. p-values are from the differential-expression test.
