Across TCGA pan-cancer cohorts, ALDH7A1P2 RNA differs between tumor and matched normal tissue in 2 of 18 cancer types tested, making tumor–normal expression one of ALDH7A1P2’s most consistent transcriptional readouts.
The strongest signal is observed in esophageal carcinoma (ESCA), where ALDH7A1P2 RNA is repressed in tumor relative to normal tissue. In most cancer types ALDH7A1P2 is over-expressed in tumor, although a few such as ESCA and LUSC show the opposite, repressed pattern.
ESCA and LUSC are the cancer types where ALDH7A1P2 tumor–normal differential expression is most reproducible.
