What is Hereditary Angioedema (HAE)? HAE is an inherited condition. If a parent has HAE, there is a 50% chance they will pass it on to their children. Family members who have been tested and who do not have HAE will not pass the disease on to their children. HAE can also occur with no family history as a spontaneous gene mutation. HAE is characterised by huge swelling of the tissues (angioedema) which last from 3 to 5 days.
