Again, in the study of Diler and Öden[13] conducted in the Turkish population, they showedthat the genotype and allele frequencies of theeNOS T786C polymorphism in PCa patients werestatistically significant, and their findings suggestedthat the eNOS T786C polymorphism might be associatedwith PCa sensitivity in the Turkish population.Another study found that the CC genotype for theeNOS T786C polymorphism increased the risk ofPCa and was associated with an increased rate ofhigh-grade and advanced disease [14]. This evidence concerns the gene NOS3 and posterior cortical atrophy.
