Summaries for Ventricular Tachycardia, Catecholaminergic Polymorphic, 2

UniProtKB/Swiss-Prot : 71 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 bidirectional tachycardia and paroxysmal ventricular fibrillation, and has symptoms including seizures, syncope and ventricular tachycardia. An important gene associated with Ventricular Tachycardia, Catecholaminergic Polymorphic, 2 is CASQ2 (Calsequestrin 2).

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
