Expression of the NKAIN1 gene is higher in the urinary sediment of PCa patients than in normal controls, and among PCa patients, NKAIN1 expression is higher in patients with Gleason scores ≥7 than in patients with Gleason scores ≤6, which suggests its utility as an early diagnostic marker of PCa [31]. This evidence concerns the gene NKAIN1 and posterior cortical atrophy.
