It is very interesting that these mediating genes are more likely cancer type-specific as approximately 97.4% of genes are identified for a single cancer while only 2.6% (i.e., a total of 14 genes, including CD79A, HPN, CBFA2T3, TACC3, KIF18B, RRM2, CIDEC, GNG7, B3GNT8, APOL2, CBX7, APOBEC3G, APOL1, and PEX11G) are shared across distinct cancers (Fig 4F). This evidence concerns the gene GNG7 and cancer.
