Across TCGA pan-cancer cohorts, DAOA RNA differs between tumor and matched normal tissue in 1 of 18 cancer types tested, making tumor–normal expression one of DAOA’s most consistent transcriptional readouts.
The strongest signal is observed in thyroid carcinoma (THCA), where DAOA RNA is repressed in tumor relative to normal tissue. In most cancer types DAOA is over-expressed in tumor, although a few such as THCA show the opposite, repressed pattern.
THCA are the cancer types where DAOA tumor–normal differential expression is most reproducible.
