Allele and genotype frequencies of the SNPs in the candidate genes

AIU, ASA-intolerant urticaria; AIA, ASA-intolerant asthma; NC, normal controls; n, number of patients; q, minor allele frequency. R, arginine; H, histidine; NS, not significant. ^*Each p value was calculated with co-dominant, dominant and recessive models.
