Have your family tested for HAE
If you have been diagnosed with HAE, it is important to talk with family members about being tested.
HAE is a genetic condition. If one parent has HAE there is a 50% chance that his or her child will have it, too.
HAE is an autosomal dominant disease, which means one copy of the altered gene in each cell is sufficient to cause the disease. So HAE is usually inherited from a parent, however, about 25% of patients develop HAE as a result of a spontaneous (non-inherited) genetic mutation. Children of these HAE patients can also inherit the disease. There are no skipped generations and no “carriers” of HAE.
Testing is the first step
HAE is a condition that, with support and treatment, can be successfully managed. You can achieve lifelong health and live an active life. Testing is the first step.
