  1. aC/C, C/R, and R/R represent homozygotes for common allele (C/C), heterozygotes (C/R) and homozygotes for rare allele (R/R). Genotype and haplotype distributions, means and standard deviations (SD) of Log (total IgE), and P values of codominant models for regression analyses were shown. Log (total IgE) was highly associated with age, gender, and atopy among bronchial asthma patients (P<0.0001). Male, atopic, and younger patient were showing higher levels of Log (total IgE). Smoking (categorized as nonsmoker, ex-smoker, and smoker) was not added in analysis because it had no significant association with Log (total IgE) (P=0.07)
