Among the four DPP4 loci, we observed that PCa patients who carried at least one minor allele (AG and GG) of rs7608798 had a significantly higher risk of developing advanced cT stages (cT3 + 4) (OR: 1.680‐fold; 95% CI: 1.062–2.659; p = 0.025) compared to patients carrying the wild‐type (WT) homozygotes (AA) (Table 3). This evidence concerns the gene DPP4 and posterior cortical atrophy.
