To better understand the role of the variants in conferring NOA risk, we selected four GWAS loci (HLA-DRA rs3129878, PRMT6 rs12097821, SOX5 rs10842262, and PEX10 rs2477686) that were reported before 2014 to investigate their association with NOA and their potential effects on sperm production in 1177 Han males from southwest China, including 545 patients with idiopathic NOA and 632 controls with normozoospermia.
The combined analyses identified significant (P < 5.0 × 10(-8)) associations between NOA risk and common variants near PRMT6 (rs12097821 at 1p13.3: odds ratio (OR) = 1.25, P = 5.7 × 10(-10)), PEX10 (rs2477686 at 1p36.32: OR = 1.39, P = 5.7 × 10(-12)) and SOX5 (rs10842262 at 12p12.1: OR = 1.23, P = 2.3 × 10(-9)).
