Across TCGA pan-cancer cohorts, FGD3 mass-spec protein differs between tumor and matched normal tissue in 4 of 18 cancer types tested, making tumor–normal expression one of FGD3’s most consistent transcriptional readouts.
The strongest signal is observed in lung adenocarcinoma (LUAD), where FGD3 mass-spec protein is repressed in tumor relative to normal tissue. In most cancer types FGD3 is over-expressed in tumor, although a few such as LUAD and LSCC show the opposite, repressed pattern.
LUAD, LSCC, and CCRCC are the cancer types where FGD3 tumor–normal differential expression is most reproducible.
