Episode 26 – HAE and plasminogen mutation

What are the clinical signs, symptoms, and pathomechanisms of HAE caused by a plasminogen mutation, a recently identified cause of HAE with normal C1 inhibitor activity? Dr Thomas Buttgereit and Dr Andreas Recke discuss this rare type of recurrent HAE, which can manifest for the first time in older adults, and note how “this is atypical for a genetic disease – normally, genetic diseases are hard-wired”.
