Idiopathic pulmonary arterial hypertension (formerly primary pulmonary hypertension) can affect more than one member of the same family. In the past 25 years scientists have exposed the inheritance pattern and a major element of the molecular basis for inherited pulmonary arterial hypertension. Familial pulmonary arterial hypertension is inherited as an autosomal dominant trait with incomplete penetrance (i.e., several individuals inherit a predisposition to the disease, but never express it). Mutations in the gene that codes for bone morphogenetic protein receptor type II (BMPR-II) are a major predisposition for the development of pulmonary arterial hypertension. These mutations are present in at least half of familial cases of pulmonary arterial hypertension and 10 to 25% of idiopathic pulmonary arterial hypertension patients. Mutations in the gene that codes for activin receptor-like kinase (ALK 1), another transforming growth factor beta (TGF-beta) cell surface receptor, appear responsible for the rare occurrence of pulmonary arterial hypertension in patients with hereditary hemorrhagic telangiectasia. These discoveries coupled with other basic investigations offer opportunities for advances in the management of pulmonary arterial hypertension.
