MYC and posterior cortical atrophy: Good correlations between the new and existing gene set scores over all PCa samples were observed (r = 0.62 and r = 0.88 for ESC/ESC_New and MYC+/MYC_New, respectively), despite poor overlap of genes both from the new and the existing gene sets (only 28 of 189 for ESC and 18 of 355 for MYC).
