A deficiency of functionally active C1-INH may lead to life threatening angioedema. Two major forms of C1-INH deficiency have been reported: congenital and acquired. The acquired form is associated with a variety of diseases including lymphoid malignancies. Due to the variable nature of the symptoms over the course of disease, definitive diagnosis should be made through the demonstration of marked reduction in functional C1-INH levels. There are two types of hereditary angioedema. Low levels of functional C1-INH as well as low levels of antigen are seen in 85% of patients; low levels of functional C1-INH, but increased or normal levels of C1-INH antigen are seen in 15% of patients.
