By sorting the results of the CBioPortal database survival data and conducting prognostic survival analysis, it was found that four of the key genes, including ACACB, GDPD3, MZB1, and SCN7A, were significantly associated with overall CRC survival (Figures 4(a), 4(b), 4(c), and 4(d)). The gene discussed is SCN7A; the disease is colorectal carcinoma.
