According to the analysis of the expression of AD000684.2 positively regulated genes (SLC23A3, CPT1B, MSH5, KAT2A, and LYG1) of PCa in the TCGA database, these five genes were highly expressed in PCa tissue (Figure 3C), and survival curve analysis showed that these five genes had a certain prognostic value (Figure 3D). The gene discussed is KAT2A; the disease is posterior cortical atrophy.
