Allele frequencies for polymorphisms are as follows: Q192R, Q = 0.359, R = 0.641; −108C/T, C = 0.544, T = 0.456; and L55M, L = 0.972, M = 0.028. No individuals were homozygous for the M allele in this cohort. Data are mean ± SD. Statistical significance between genotypes was analyzed by one-way ANOVA and Scheffe test.
