Across TCGA pan-cancer cohorts, SCNN1G mass-spec protein differs between tumor and matched normal tissue in 1 of 18 cancer types tested, making tumor–normal expression one of SCNN1G’s most consistent transcriptional readouts.
The strongest signal is observed in clear cell renal cell carcinoma (CCRCC), where SCNN1G mass-spec protein is repressed in tumor relative to normal tissue. In most cancer types SCNN1G is over-expressed in tumor, although a few such as CCRCC show the opposite, repressed pattern.
CCRCC are the cancer types where SCNN1G tumor–normal differential expression is most reproducible.
