We used bioinformatics to analyze RNA sequencing (RNA-Seq) data from tissue gene expression profiles in the TCGA database, mined new genes closely related to prognosis, analyzed the relation of low AP004608.1 expression and OS and PFS in PCa patients, and assessed the prognostic significance of AP004608.1 expression as an in-dependent biomarker for OS (28–31). The gene discussed is B3GAT1-DT; the disease is posterior cortical atrophy.
