Across TCGA pan-cancer cohorts, CACNG2 RNA differs between tumor and matched normal tissue in 4 of 18 cancer types tested, making tumor–normal expression one of CACNG2’s most consistent transcriptional readouts.
The strongest signal is observed in thyroid carcinoma (THCA), where CACNG2 RNA is repressed in tumor relative to normal tissue. In most cancer types CACNG2 is over-expressed in tumor, although a few such as THCA and BRCA show the opposite, repressed pattern.
THCA, LUAD, and LUSC are the cancer types where CACNG2 tumor–normal differential expression is most reproducible.
