Across TCGA pan-cancer cohorts, NCAM1-AS1 RNA differs between tumor and matched normal tissue in 10 of 18 cancer types tested, making tumor–normal expression one of NCAM1-AS1’s most consistent transcriptional readouts.
The strongest signal is observed in thyroid carcinoma (THCA), where NCAM1-AS1 RNA is repressed in tumor relative to normal tissue. In most cancer types NCAM1-AS1 is over-expressed in tumor, although a few such as THCA and BLCA show the opposite, repressed pattern.
THCA, BLCA, and COAD are the cancer types where NCAM1-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 NCAM1-AS1 RNA (log2); positive values indicate higher expression in tumor. p-values are from the differential-expression test.
