Channelopathy Genes in Pulmonary Arterial Hypertension

Carrie L. Welch, Wendy K. ChungColumbia University Irving Medical Center.United States BiomoleculesBiomolecules 2022; 12: DOI: 10.3390/biom12020265 AbstractPulmonary arterial hypertension (PAH) is a rare, progressive vasculopathy with significant cardiopulmonary morbidity and mortality. The underlying pathogenetic mechanisms are heterogeneous and current therapies aim to decrease pulmonary vascular resistance but no curative treatments are available. Causal genetic variants can
