PIK3CA and posterior cortical atrophy: Common oncogenes and tumour suppressor genes whose CNA statuses were confirmed to have association with the disease stage at a p-value of <0.05 in this study included CCND1, CCNE1, CDKN1B, CDKN2A, CHD1, MYC, PIK3CA, PTEN, RB1, FGFR1, BCL2, and TP53. In addition, the PCa-specific genes confirmed to have significant associations with the disease stage included AR, NCOR1, NCOR2, FOXA1, MED12, ERG, ETV4, ETV6, and TMPRSS2.
