PURPOSE OF REVIEW: The identification of the genetic basis for heritable predisposition to pulmonary arterial hypertension (PAH) has altered the clinical and research landscape for PAH patients and their care providers. This review aims to describe the genetic discoveries and their impact on clinical medicine.
RECENT FINDINGS: Since the landmark discovery that bone morphogenetic protein receptor type II (BMPR2) mutations cause the majority of cases of familial PAH, investigators have discovered mutations in genes that cause PAH in families without BMPR2 mutations, including the type I receptor ACVRL1 and the type III receptor ENG (both associated with hereditary hemorrhagic telangiectasia), caveolin-1 (CAV1), and a gene (KCNK3) encoding a two-pore potassium channel. Mutations in these genes cause an autosomal-dominant predisposition to PAH in which a fraction of mutation carriers develop PAH (incomplete penetrance). In 2014, scientists discovered mutations in eukaryotic initiation factor 2 alpha kinase 4 (EIF2AK4) that cause pulmonary capillary hemangiomatosis and pulmonary veno-occlusive disease, an autosomal recessively inherited disorder.
SUMMARY: The discovery that some forms of pulmonary hypertension are heritable and can be genetically defined adds important opportunities for physicians to educate their patients and their families to understand the potential risks and benefits of genetic testing.
