摘　　要：Hereditary angioedema(HAE)is an uncommon genetic disorder characterized by recurrent episodes of edema involving subcutaneous tissue and submucosa.The pathogenesis of HAE reflects an intricate coordinated regulation of components of complement,kinin and hemostatic pathway.Till date,mutations in 4 different genes have been identified to cause HAE which includes serine protease inhibitor G1(SERPING1),factor XII(F12),plasminogen(PLG)and angiopoietin 1(ANGPT 1).These mutations lead to increased bradykinin 2 receptor mediated signalling via increased production of bradykinin except mutations in ANGPT1 gene that disturbs the cytoskeletal assembly of vascular endothelial cells.In this review we aim to summarize the recent advances in the pathogenesis and genetics of HAE.We also provide an overview of possible future prospects in the identification of new genetic defects in HAE.
