Secondly, the GEPIA2 database provided the top 100 correlated genes with CDKN2A under tumor conditions where the correlation plots of the top four true genes are shown in Figure 11C. It is worth mentioning that two proteins, namely E2FA and MCM2, were detected as common genes in the generated lists of the two employed databases (Figure 11B). The gene discussed is MCM2; the disease is neoplasm.
