KCNAB1-AS1

Across TCGA pan-cancer cohorts, KCNAB1-AS1 RNA differs between tumor and matched normal tissue in 3 of 18 cancer types tested, making tumor–normal expression one of KCNAB1-AS1’s most consistent transcriptional readouts.

The strongest signal is observed in breast invasive carcinoma (BRCA), where KCNAB1-AS1 RNA is repressed in tumor relative to normal tissue. In most cancer types KCNAB1-AS1 is over-expressed in tumor, although a few such as BRCA and THCA show the opposite, repressed pattern.

BRCA, THCA, and LUAD are the cancer types where KCNAB1-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 KCNAB1-AS1 RNA (log₂); positive values indicate higher expression in tumor. p-values are from the differential-expression test.
