Across TCGA pan-cancer cohorts, VSTM2B RNA differs between tumor and matched normal tissue in 3 of 18 cancer types tested, making tumor–normal expression one of VSTM2B’s most consistent transcriptional readouts.
The strongest signal is observed in stomach adenocarcinoma (STAD), where VSTM2B RNA is repressed in tumor relative to normal tissue. In most cancer types VSTM2B is over-expressed in tumor, although a few such as STAD and KIRP show the opposite, repressed pattern.
STAD, KIRP, and LIHC are the cancer types where VSTM2B tumor–normal differential expression is most reproducible.
