For hereditary angioedema type III, genetic testing should only be considered when there is a documented family history of angioedema that does not respond to chronic, high-dose antihistamine therapy, normal complement studies, normal C1 inhibitor level and function, and no exposure to medications that could cause angioedema, such as . The term "angio" is derived from the Greek word for "vessel," in this case . The key to what goes wrong in hereditary angioedema is in the name of the disorder. Clinical definition. 3. Acquired angioedema (AAE) is a rare disorder that causes recurrent episodes of swelling (edema) of the face or body, lasting several days. Other forms of Hereditary Angioedema HAE with normal C1-INH is generally diagnosed by clinical presentation, although now testing for FXII involvement is available. 1. In contrast to acquired angioedema, which is a secondary process, HAE is associated with genetic variations. A new, highly sensitive genetic test that screens the entire SERPING1 gene is better than conventional genetic testing for diagnosing type 1 and type 2 hereditary angioedema, new research shows.. Because of the rarity of HAE, a diagnosis is often delayed. Hereditary angioedema, initially described by Osler in 1888, is an autosomal dominant disease caused by a deficiency in functional C1 inhibitor. Patients most commonly present with swelling of the lips, tongue, or face, although another presentation is episodic abdominal pain due to intestinal angioedema.

Hereditary angioedema (HAE) is a disease characterized by recurrent episodes (also called attacks) of severe swelling of the skin and mucous membranes. Hereditary angioedema (HAE) is caused by a gene defect you inherit or develop at conception. During acute attacks of the disease, complement factors C 4 and C 2 can be markedly reduced, but C 1 and C 3 are normal. Because HAE shares many symptoms in common with other conditions, it is often misdiagnosed. The estimated frequency of HAE is 1:50,000 persons. Hereditary angioedema due to C1 inhibitor deficiency (C1-INH-HAE) is an autosomal dominant disease resulting in random and unpredictable attacks of swelling.
