HWE: Hardy-Weinberg equilibrium; Call-rate: rate of successful genotyping. All variants passed initial quality-control criteria with a call-rate ≥95% and genotype distribution were in Hardy-Weinberg equilibrium (P>0.05). The genotype distribution and effect allele frequencies varied from 17.7% for rs987237 to 83.7% for rs654238), which were in consistency with previous reports.
