These studies identified transmembrane protein 256 and LAMTOR1 (Øverbye et al. 2015), flotillin 2 and Rab3B (Wang et al. 2017), FABP5 (Fujita et al. 2017), among others (Fujita et al. 2017; Sequeiros et al. 2017) as PCa-specific urine biomarkers. The gene discussed is TMEM256; the disease is posterior cortical atrophy.
