Only occasionally will it become clinically manifest like through an anaphylactic reaction to a NMBA, through the referral of patients to allergy clinics for elevated IgE and IgE antibodies of unclear etiology and questionable clinical consequence, or through the odd patient with severe allergic bronchial asthma who is excluded from the treatment option with anti-IgE because the IgE apparently unexplained has become too high and out of range for the capacity of this treatments. The gene discussed is IGHE; the disease is Allergy.
