title: Hereditary angioedema: polymorphism.
abstract: Four patients with hereditary angioedema were studied. All had low values of C4, C1 INH, (CH 50) complement activity and circulating immune complexes. This report takes into account the different aspects that this disease can present, often quite different from the classical description of hereditary angioedema.
