Summaries for Long Qt Syndrome 6

About this section
OMIM® : 57 Congenital long QT syndrome is electrocardiographically characterized by a prolonged QT interval and polymorphic ventricular arrhythmias (torsade de pointes). These cardiac arrhythmias may result in recurrent syncope, seizure, or sudden death (Jongbloed et al., 1999). For a discussion of genetic heterogeneity of long QT syndrome, see LQT1 (192500). (613693) (Updated 05-Mar-2021)

MalaCards based summary : Long Qt Syndrome 6, also known as lqt6, is related to periodic paralysis and progressive familial heart block, type ia, and has symptoms including syncope An important gene associated with Long Qt Syndrome 6 is KCNE2 (Potassium Voltage-Gated Channel Subfamily E Regulatory Subunit 2), and among its related pathways/superpathways are Transmission across Chemical Synapses and Cardiac conduction. Affiliated tissues include heart, and related phenotypes are sudden cardiac death and prolonged qt interval

Disease Ontology : 12 A long QT interval syndrome that has material basis in dominant inheritance of mutation in the KCNE2 gene on chromosome 21q22.11.

UniProtKB/Swiss-Prot : 73 Long QT syndrome 6: A heart disorder characterized by a prolonged QT interval on the ECG and polymorphic ventricular arrhythmias. They cause syncope and sudden death in response to exercise or emotional stress, and can present with a sentinel event of sudden cardiac death in infancy.
