Summaries for Long Qt Syndrome 5

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). (613695) (Updated 05-Mar-2021)

MalaCards based summary : Long Qt Syndrome 5, also known as lqt5, is related to ventricular fibrillation, paroxysmal familial, 1 and jervell and lange-nielsen syndrome 1, and has symptoms including syncope An important gene associated with Long Qt Syndrome 5 is KCNE1 (Potassium Voltage-Gated Channel Subfamily E Regulatory Subunit 1), and among its related pathways/superpathways are cGMP-PKG signaling pathway and Dopamine-DARPP32 Feedback onto cAMP Pathway. Affiliated tissues include heart, and related phenotypes are sudden cardiac death and prolonged qt interval

Disease Ontology : 12 A long QT syndrome that has material basis in dominant inheritance of mutation in the KCNE1 gene on chromosome 21q22.12.

UniProtKB/Swiss-Prot : 73 Long QT syndrome 5: 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.
