Across TCGA pan-cancer cohorts, MTATP6P4 RNA differs between tumor and matched normal tissue in 2 of 18 cancer types tested, making tumor–normal expression one of MTATP6P4’s most consistent transcriptional readouts.
The strongest signal is observed in stomach adenocarcinoma (STAD), where MTATP6P4 RNA is more highly expressed in tumor relative to normal tissue. In most cancer types MTATP6P4 is over-expressed in tumor.
STAD and BRCA are the cancer types where MTATP6P4 tumor–normal differential expression is most reproducible.
