Table 2 shows the overlap between the reference signature behavior from database 1 and the behavior of genes in database 2. The overlap amounts to 28 genes (29 probes with two probes for gene SMC4), which is 71.8% of the original signature, evidencing the effectiveness of the method. Table 2 also summarizes evidence found in the literature to support the genes' potential biomarking role in cervix cancer or in other types of cancer. This evidence concerns the gene SMC4 and cancer.
