Summaries for Ventricular Tachycardia, Catecholaminergic Polymorphic, 2

UniProtKB/Swiss-Prot : 76 Ventricular tachycardia, catecholaminergic polymorphic, 2: An arrhythmogenic disorder characterized by stress-induced, bidirectional ventricular tachycardia that may degenerate into cardiac arrest and cause sudden death. Patients present with recurrent syncope, seizures, or sudden death after physical activity or emotional stress. CPVT2 inheritance is autosomal recessive.

MalaCards based summary : Ventricular Tachycardia, Catecholaminergic Polymorphic, 2, also known as stress-induced polymorphic ventricular tachycardia, is related to ventricular tachycardia, catecholaminergic polymorphic, 1, with or without atrial dysfunction and/or dilated cardiomyopathy and catecholaminergic polymorphic ventricular tachycardia, and has symptoms including seizures and syncope. An important gene associated with Ventricular Tachycardia, Catecholaminergic Polymorphic, 2 is CASQ2 (Calsequestrin 2), and among its related pathways/superpathways are Myometrial Relaxation and Contraction Pathways and Antiarrhythmic Pathway, Pharmacodynamics. The drugs Metoprolol and Nadolol have been mentioned in the context of this disorder. Affiliated tissues include heart and testes, and related phenotypes are seizures and syncope

Disease Ontology : 12 A catecholaminergic polymorphic ventricular tachycardia that is characterized by autosomal recessive inheritance and has material basis in homozygous or compound heterozygous mutation in the CASQ2 gene on chromosome 1p13.
