We analyzed the circulating mRNAs in 84 urine samples to confirm the clinical utility of HAZIS‐CirR for circulating mRNA‐based PCa diagnosis (Figure S6) using the PCA3 and the TMPRSS2‐ERG gene fusion as the biomarkers and the relative quantification (RQ) values were calculated (Figure 4a,b). The gene discussed is ERG; the disease is posterior cortical atrophy.
