TTN-AS1

Across TCGA pan-cancer cohorts, TTN-AS1 RNA differs between tumor and matched normal tissue in 7 of 18 cancer types tested, making tumor–normal expression one of TTN-AS1’s most consistent transcriptional readouts.

The strongest signal is observed in head and neck squamous cell carcinoma (HNSC), where TTN-AS1 RNA is more highly expressed in tumor relative to normal tissue. In most cancer types TTN-AS1 is over-expressed in tumor, although a few such as KICH and BRCA show the opposite, repressed pattern.

HNSC, KICH, and BRCA are the cancer types where TTN-AS1 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 TTN-AS1 RNA (log₂); positive values indicate higher expression in tumor. p-values are from the differential-expression test.
