Gene expression was further verified using qRT-PCR and together with statistical analysis, yielded a panel of seven genes (CTAM, CXCR3(CD183), FCRL3, KIAA1143, KLF12, TMEM204, SAMSN1) that could distinguish between aggressive PCa and healthy patients with a high sensitivity and specificity rate (83% and 80% respectively). This evidence concerns the gene CXCR3 and posterior cortical atrophy.
