Hereditary angioedema-5 (HAE5) is an autosomal dominant disorder characterized by localized and self-limiting edema of the subcutaneous or submucosal tissue due to an episodic increase in vascular permeability. Affected individuals have onset of episodic swelling of the face, lips, hands, and abdomen in the second decade of life. Treatment with tranexamic acid may be effective in reducing the severity and frequency of the attacks (summary by Bafunno et al., 2018). For a discussion of genetic heterogeneity of hereditary angioedema, see 106100. [from OMIM]

Hereditary angioedema-7 (HAE7) is an autosomal dominant disorder characterized by onset of recurrent episodic swelling of the face, lips, and oral mucosa in the second decade. The disorder is due to abnormal vascular permeability (summary by Ariano et al., 2020). For a discussion of genetic heterogeneity of HAE, see 106100. [from OMIM]
