Familial hyperaldosteronism (FHPA) is an inherited type of primary aldosteronism (PA). With the rapid development of genomics and molecular biology, the pathogenesis, genetic background and clinical management strategies of FHPA have been deeply studied. However, there is relatively little understanding of this disease in China. This article introduces the genetic characteristics, diagnosis and treatment methods of patients with FHPA. Its purpose is to enhance the awareness and diagnostic and treatment capabilities of domestic medical personnel towards this rare disease.
