On the other hand, our findings do not support the hypothesis for increased PCa incidences in HLA-A2+ patients: among 187 PCa patients, the HLA-A*02:01 phenotype frequency was decreased compared to the general Greek population (36.36% vs. ≈43%), whereby the HLA-A*24:02 was overrepresented (36.36% vs. ≈22%) (unpublished data including the 56 de novo mPCa patients of the current study), thus disputing the hypothesis of HLA-A2 as a risk factor for PCa. The gene discussed is HLA-A; the disease is posterior cortical atrophy.
