FCER1A is involved in inducing the inflammatory and immediate hypersensitivity responses in allergic disorders such as hay fever, asthma, and chronic idiopathic urticaria (Bleehen et al., 1987; Bruhn, 2011; Chandrashekhar et al., 2011; Rueff et al., 2011). This evidence concerns the gene FCER1A and chronic idiopathic urticaria.
