Patients experience bradycardia or ventricular tachyarrhythmias that may result in syncope, cardiac arrest, and/or sudden death (Reed et al., 2015; Wren et al., 2019).&#13; Patients with LQT14 (616247), LQT15 (616249), or LQT16, resulting from mutation in calmodulin genes CALM1 (114180), CALM2 (114182), or CALM3, respectively, typically have a more severe phenotype, with earlier onset, profound QT prolongation, and a high predilection for cardiac arrest and sudden death, than patients with mutations in other genes (Boczek et al., 2016).&#13; CPVT6&#13; Catecholaminergic polymorphic ventricular tachycardia-6 (CPVT6) is characterized by childhood-onset syncopal episodes with exercise or stress. Electrocardiogram (ECG) shows a normal QT interval with a prominent U wave, and stress testing reveals premature ventricular contractions (PVCs) that may occur as bigeminy or couplets, and nonsustained ventricular tachycardia (Gomez-Hurtado et al., 2016)." /><meta name="robots" content="index,nofollow,noarchive" />

<div class="portlet_content ln">LQT16&#13; Long QT syndrome-16 (LQT16) is characterized by a markedly prolonged corrected QT (QTc) interval and 2:1 atrioventricular (AV) block, with onset in the perinatal period. Patients experience bradycardia or ventricular tachyarrhythmias that may result in syncope, cardiac arrest, and/or sudden death (Reed et al., 2015; Wren et al., 2019).&#13; Patients with LQT14 (616247), LQT15 (616249), or LQT16, resulting from mutation in calmodulin genes CALM1 (114180), CALM2 (114182), or CALM3, respectively, typically have a more severe phenotype, with earlier onset, profound QT prolongation, and a high predilection for cardiac arrest and sudden death, than patients with mutations in other genes (Boczek et al., 2016).&#13; CPVT6&#13; Catecholaminergic polymorphic ventricular tachycardia-6 (CPVT6) is characterized by childhood-onset syncopal episodes with exercise or stress. Electrocardiogram (ECG) shows a normal QT interval with a prominent U wave, and stress testing reveals premature ventricular contractions (PVCs) that may occur as bigeminy or couplets, and nonsustained ventricular tachycardia (Gomez-Hurtado et al., 2016). [from <a title="Online Mendelian Inheritance in Man" href="http://www.omim.org" class="defSource" target="_blank">OMIM</a>]</div>
