摘要

Cl inhibitor (Cl-INH) deficiency (hereditary or acquired angioedema; HAE [OMIM106100] or AAE) is characterized by recurring episodes of subcutaneous or submucosal swellings, typically involving the face, limbs, tongue, bowels or upper airways [1]. Laryngeal attack can cause airway obstruction which may be fatal. Therefore, prompt diagnosis and treatment are essential. Two classical types of HAE, type 1 and 2, are autosomal dominant disorders due to heterozygous deficiencies of the Cl-INH gene (SERPING1). Type 1 shows decreased antigenic and functional levels of Cl-INH and type 2 shows normal levels of antigenic Cl-INH but low levels of functional Cl-INH [2].
