Across TCGA pan-cancer cohorts, GFRA3 mass-spec protein differs between tumor and matched normal tissue in 2 of 18 cancer types tested, making tumor–normal expression one of GFRA3’s most consistent transcriptional readouts.
The strongest signal is observed in lung adenocarcinoma (LUAD), where GFRA3 mass-spec protein is more highly expressed in tumor relative to normal tissue. In most cancer types GFRA3 is over-expressed in tumor, although a few such as COAD show the opposite, repressed pattern.
LUAD and COAD are the cancer types where GFRA3 tumor–normal differential expression is most reproducible.
