Hereditary Angioedema (HAE) Type III
Hereditary angioedema type III is characterized primarily by skin swellings (predominantly facial) and abdominal attacks. Additional symptoms that may occur are tongue swellings, laryngeal edemas and swellings of the soft palate. Affected individuals are predominantly women, though men can be affected, typically at a later age of onset and with less frequency and severity of […]
