IGHE and asthma: No significant difference was observed when individually comparing the median log IgE (according to 1.99) among patients with the CC, CT, TT genotypes of the CD14C-159 T polymorphism (p = 0.08); in the asthma group, presence of the C allele (CC + CT) was more frequent among those with low IgE levels, but no statistically significant difference was detected (p = 0.09, Figure 1A).
