Summaries for Pulmonary Hypertension, Primary, 4

OMIM : 58 Primary pulmonary hypertension is a rare progressive disease characterized by increased pulmonary artery pressure in the absence of common causes of pulmonary hypertension, such as chronic heart, lung, or thromboembolic disease. There is often vascular remodeling. The clinical presentation can be nonspecific, and patients often receive a diagnosis late in their clinical course (summary by Ma et al., 2013). For a general phenotypic description and a discussion of genetic heterogeneity of primary pulmonary hypertension, see PPH1 (178600). (615344)

MalaCards based summary : Pulmonary Hypertension, Primary, 4, is also known as primary pulmonary hypertension 4. An important gene associated with Pulmonary Hypertension, Primary, 4 is KCNK3 (Potassium Two Pore Domain Channel Subfamily K Member 3). The drugs Spironolactone and Natriuretic Peptide, Brain have been mentioned in the context of this disorder. Affiliated tissues include endothelial and brain, and related phenotypes are arrhythmia and pulmonary arterial hypertension

UniProtKB/Swiss-Prot : 76 Pulmonary hypertension, primary, 4: A rare disorder characterized by plexiform lesions of proliferating endothelial cells in pulmonary arterioles. The lesions lead to elevated pulmonary arterial pression, right ventricular failure, and death. The disease can occur from infancy throughout life and it has a mean age at onset of 36 years. Penetrance is reduced. Although familial pulmonary hypertension is rare, cases secondary to known etiologies are more common and include those associated with the appetite-suppressant drugs.
