Across TCGA pan-cancer cohorts, SDHDP5 RNA differs between tumor and matched normal tissue in 2 of 18 cancer types tested, making tumor–normal expression one of SDHDP5’s most consistent transcriptional readouts.
The strongest signal is observed in thyroid carcinoma (THCA), where SDHDP5 RNA is repressed in tumor relative to normal tissue. In most cancer types SDHDP5 is over-expressed in tumor, although a few such as THCA show the opposite, repressed pattern.
THCA and KIRP are the cancer types where SDHDP5 tumor–normal differential expression is most reproducible.
