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. This evidence concerns the gene TMEM38B and posterior cortical atrophy.
