Implications of mutations of activin receptor-like kinase 1 gene (ALK1) in addition to bone morphogenetic protein receptor II gene (BMPR2) in children with pulmonary arterial hypertension.

Abstract excerpt

BACKGROUND: Mutations of the bone morphogenetic protein receptor II gene (BMPR2), and 1 mutation of the activin receptor-like kinase 1 gene (ALK1) have been reported in patients with pulmonary arterial hypertension (PAH). METHODS AND RESULTS: A genomic study of ALK1 and BMPR2 was conducted in 21 PAH probands under 16 years of age to study the relationship between the clinical features of the patients and these...
