Across TCGA pan-cancer cohorts, TOMM22P2 RNA differs between tumor and matched normal tissue in 2 of 18 cancer types tested, making tumor–normal expression one of TOMM22P2’s most consistent transcriptional readouts.
The strongest signal is observed in kidney renal clear cell carcinoma (KIRC), where TOMM22P2 RNA is repressed in tumor relative to normal tissue. In most cancer types TOMM22P2 is over-expressed in tumor, although a few such as KIRC and KICH show the opposite, repressed pattern.
KIRC and KICH are the cancer types where TOMM22P2 tumor–normal differential expression is most reproducible.
