Methods. BMPR2 gene mutations were determined using nucleic acid sequencing in 24 patients with pulmonary arterial hypertension and scleroderma spectrum of disease and in 2 control groups, 96 healthy North American individuals and 100 Israeli Ashkenazi Jews. The patients also had antinuclear antibody determinations and underwent right heart catheterization. RESULTS: One BMPR2 guanine to adenine (G to A) mutation in exon 13 was found in a 59-year-old Ashkenazi Jewish woman with the limited cutaneous variant, a normal chest radiograph, and positive anticentromere and rheumatoid factor autoantibodies. However, this mutation is thought to be a polymorphism because the same mutation was also found in an ethnically matched healthy Ashkenazi Jew. CONCLUSION: Pulmonary arterial hypertension in scleroderma spectrum of disease was not associated with heterogeneous germline mutations of BMPR2.
