HAE is a rare, life-long condition characterized by attacks of swelling § Rare and potentially life-threatening genetic condition § 1:10,000 to 1:50,000 Individuals affected by HAE globally ‒ At least 6,600 people living with HAE in the U.S. ‒ At least 8,900 people living with HAE in Europe ‒ Globally, under-diagnosed/treated Nordenfelt et al, Acta Derm.
