The bone morphogenic protein receptor 2 (BMPR2) is a member of the transforming growth factor beta (TGFβ) receptor family that has been found to play a significant role in pulmonary arterial hypertension (PAH), obesity, and insulin resistance (Schleinitz et al., 2011; West et al., 2013, 2014; Viales et al., 2015). This evidence concerns the gene BMPR2 and pulmonary arterial hypertension.
