What Is HAE?

Hereditary Angioedema (HAE) is a rare genetic disorder characterized by recurrent episodes of severe swelling (angioedema) in various parts of the body, including the face, extremities, gastrointestinal tract, and airway. This condition is caused by a deficiency or dysfunction of a protein called C1 inhibitor, which plays a crucial role in regulating the immune system and blood clotting. When this protein is not functioning properly, it leads to an overproduction of certain proteins that cause inflammation and swelling.

HAE is classified into two main types:

• Type I HAE: This is the most common form, accounting for about 85% of cases. It is caused by low levels of C1 inhibitor.
• Type II HAE: This type is less common and results from normal or elevated levels of C1 inhibitor that are dysfunctional.

HAE is inherited in an autosomal dominant pattern, meaning that only one copy of the mutated gene from an affected parent can cause the disorder in their offspring. This genetic aspect makes it essential for families with a history of HAE to seek genetic counseling and testing.

Understanding the Genetics of HAE

The genetic mutation responsible for HAE occurs in the SERPING1 gene, which encodes the C1 inhibitor protein. Individuals with a family history of HAE have a 50% chance of passing the condition to their children. Understanding this genetic link is vital for early diagnosis and management of the disorder.

Why Awareness of HAE Is Important

Despite being a rare condition, awareness of HAE is crucial for timely diagnosis and treatment. Many individuals with HAE may experience misdiagnosis or delayed treatment due to the rarity of the condition. Increased awareness can lead to better management strategies and improved quality of life for those affected.

HAE Symptoms

The symptoms of HAE can vary significantly from person to person, and they often occur without warning. The most common symptoms include:

• Swelling: The hallmark symptom of HAE is recurrent swelling, which can occur in various parts of the body. This swelling can be painful and may last for several days.
• Abdominal Pain: Swelling in the gastrointestinal tract can lead to severe abdominal pain, nausea, and vomiting, often mimicking other gastrointestinal disorders.
• Respiratory Issues: Swelling in the throat or airway can be life-threatening, leading to difficulty breathing and requiring immediate medical attention.
• Facial Swelling: Many individuals experience swelling in the face, particularly around the eyes and lips, which can be distressing and impact self-esteem.
