Across TCGA pan-cancer cohorts, SPAG11A RNA differs between tumor and matched normal tissue in 2 of 18 cancer types tested, making tumor–normal expression one of SPAG11A’s most consistent transcriptional readouts.
The strongest signal is observed in breast invasive carcinoma (BRCA), where SPAG11A RNA is repressed in tumor relative to normal tissue. In most cancer types SPAG11A is over-expressed in tumor, although a few such as BRCA show the opposite, repressed pattern.
BRCA and THCA are the cancer types where SPAG11A tumor–normal differential expression is most reproducible.
