Phospholamban cardiomyopathy
WebJan 1, 2001 · Phospholamban was originally implicated in the regulation of calcium transport across the cardiac sarcoplasmic reticulum by the correlation of cAMP-induced stimulation of calcium transport by the Ca 2+ -ATPase, with the predominant phosphorylation of PLB by the cAMP-dependent protein kinase ( 110 125 213 215 ). WebThe deletion of the arginine 14 codon (R14del) in the phospholamban (PLN) gene is a rare cause of arrhythmogenic cardiomyopathy (ACM) and is associated with prevalent ventricular arrhythmias, heart failure, and sudden cardiac death. The pathophysiological mechanism which culminates in the ACM phenotype is multifactorial and mainly based on …
