Across TCGA pan-cancer cohorts, ATM RNA differs between tumor and matched normal tissue in 10 of 18 cancer types tested, making tumor–normal expression one of ATM’s most consistent transcriptional readouts.
The strongest signal is observed in kidney renal clear cell carcinoma (KIRC), where ATM RNA is more highly expressed in tumor relative to normal tissue. In most cancer types ATM is over-expressed in tumor, although a few such as THCA and UCEC show the opposite, repressed pattern.
KIRC, HNSC, and THCA are the cancer types where ATM 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 ATM RNA (log2); positive values indicate higher expression in tumor. p-values are from the differential-expression test.
