Question

Quizplus · Accepted Answer

HAE is a rare, life-threatening complement disorder that results from deficiency of C1-inhibitor (HAE-C1-INH). It is an inherited autosomal dominant trait that causesmutation in the 11th chromosome. Deficiencies in C1-INH result in uncontrolled release of vasoactive substances that promote vascular permeability. The net result is the development of swelling in the subcutaneous tissues of the extremities, face/torso, or upper airway and GI tract. Laryngeal edema is a life-threatening manifestation that can lead to complete airway obstruction and death without interventions.
