In pooled analyses, NKX3‐1 rs2228013 (GA vs. AA, OR = 1.18, 95% CI = 1.00–1.38, Pheterogeneity = 0.565, p = 0.047, Figure 4), CASP9 rs1052571 (GG + GA vs. AA, OR = 1.19, 95% CI = 1.01–1.40, Pheterogeneity = 0.850, p = 0.037, Figure 5), and CASP9 rs4645982 (GG vs. GA + AA, OR = 1.41, 95% CI = 1.03–1.93, Pheterogeneity = 0.431, p = 0.032, Figure 6) were associated with an elevated risk of PCa when evaluated using different genetic models. The gene discussed is CASP9; the disease is posterior cortical atrophy.
