Collectively, except for the five genes (COL5A2, ACPP, FOSB, SH3BGRL, and ST7) that function as important biomarkers in PCa, the significant role of another five genes (IFRD1, TUBA1A, CFAP69, TMEM38B, and MANEA) in PCa is still not demonstrated, which needs further investigation. The gene discussed is ST7; the disease is posterior cortical atrophy.
