An international team has identified a protein-degradation mechanism that contributes to the development of an inherited form of catecholaminergic polymorphic ventricular tachycardia (CPVT), a disease that mainly affects children and young people. The study was led by researchers at the Centro Nacional de Investigaciones Cardiovasculares Carlos III (CNIC), in collaboration with the University of Pavia and IRCCS Istituti Clinici Scientifici Maugeri in Italy.
