Symbol PPH4
Location 2p23.3
Name pulmonary hypertension, primary, 4
Corresponding gene KCNK3
Main clinical features
  • rare progressive disease characterized by increased pulmonary artery pressure in the absence of common causes of pulmonary hypertension
  • increased pulmonary vascular resistance and sustained elevation of mean pulmonary arterial pressure, leading to right ventricular hypertrophy and right heart failure
  • pulmonary vascular remodeling of all layers of pulmonary arterial vessels: intimal thickening, smooth muscle cell hypertrophy
  • Genetic determination autosomal dominant
    Function/system disorder respiratory
    Type disease
