IGHE and asthma: In another report, among aspirin-intolerant chronic urticaria (AICU) and aspirin-intolerant asthma (AIA) patients, those who have −344T allele not only indicated a higher atopy rate (among AIA patients, those who had −344T allele were 59.46%; among AICU patients, those who had −344T allele were 84.1%) but also total serum IgE concentrations compared to those with the homozygous −344C/C genotype [66,69].
