Across TCGA pan-cancer cohorts, RORA-AS2 RNA differs between tumor and matched normal tissue in 2 of 18 cancer types tested, making tumor–normal expression one of RORA-AS2’s most consistent transcriptional readouts.
The strongest signal is observed in thyroid carcinoma (THCA), where RORA-AS2 RNA is repressed in tumor relative to normal tissue. In most cancer types RORA-AS2 is over-expressed in tumor, although a few such as THCA and LIHC show the opposite, repressed pattern.
THCA, LIHC, and LIHC are the cancer types where RORA-AS2 tumor–normal differential expression is most reproducible.
