Summaries for Long Qt Syndrome 5

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)

MalaCards based summary : Long Qt Syndrome 5, also known as lqt5, is related to long qt syndrome 2 and long qt syndrome, 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 Circadian entrainment and Aldosterone synthesis and secretion. Affiliated tissues include heart, and related phenotypes are syncope and sudden cardiac death

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 : ⁷⁵ 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.
