CI: confidence interval; odds ratio (OR) between groups was determined by logistic regression. : value calculated by chi-squared test or Fisher’s exact test for difference in allele and genotype frequency between cases and controls. * value after Bonferroni’s correction. The allele frequency statistically significant is shown in italic. Significant values are shown in boldface ( value <0.05).
