Hereditary Angioedema Clinical Trials

HAE is a rare genetic condition characterized by spontaneous swelling that can be life-threatening by blocking airways and preventing breathing. The main type of HAE is caused by mutations in the SERPING1 gene. This gene encodes a protein called C1-INH which plays an important role in controlling certain types of swelling in the body. When C1-INH is missing or not working correctly, sudden, unexpected swelling events can occur.
