Across TCGA pan-cancer cohorts, FAM234A mass-spec protein differs between tumor and matched normal tissue in 3 of 18 cancer types tested, making tumor–normal expression one of FAM234A’s most consistent transcriptional readouts.
The strongest signal is observed in colon adenocarcinoma (COAD), where FAM234A mass-spec protein is repressed in tumor relative to normal tissue. In most cancer types FAM234A is over-expressed in tumor, although a few such as COAD and CCRCC show the opposite, repressed pattern.
COAD, CCRCC, and PDAC are the cancer types where FAM234A tumor–normal differential expression is most reproducible.
