Introduction: Heterozygous germline mutations of the bone morphogenetic protein type II receptor (BMPR 2) gene BMPR2 are the most important predisposing factors for heritable pulmonary arterial hypertension. BMPR2 mutation was occasionally reported in pulmonary veno-occlusive disease, appetite suppressant-related pulmonary arterial hypertension (PAH), and PAH with congenital heart disease. Materials and Methods: In this study we identified a missense mutation (c.2296A > G) located in BMPR2 exon 12 in a patient with chronic thromboembolic pulmonary hypertension (CTEPH). Conclusion: It is the first report of a BMPR2 mutation in CTEPH. Our study provides innovative insight into etiology of CTEPH. The genetic predisposing factor is an important component in the process of this CTEPH patient.

    For more than 60 years, researchers have sought to understand the molecular basis of idiopathic pulmonary arterial hypertension (PAH). Recognition of the heritable form of the disease led to the creation of patient registries in the 1980s and 1990s, and discovery of BMPR2 as the cause of roughly...
