Heritable pulmonary arterial hypertension

Abstract

Heritable pulmonary arterial hypertension (PAH) can be triggered by at least 18genes. The most frequently altered gene is the bone morphogenetic protein receptor2 (BMPR2). Further genes from the same pathway are also well known PAH-causing genes. Genetic testing can aid to confirm differential diagnoses such as apulmonary veno-occlusive disease. It also enables the testing of healthy family members. In addition to the PAH patient population particularly served by genetic testing, this article touches on the mode of inheritance and provides insights into the first treatments soon on the market that rebalance the BMPR2 signaling pathway.
