Summaries for Long Qt Syndrome 1

Genetics Home Reference : 25 Romano-Ward syndrome is a condition that causes a disruption of the heart's normal rhythm (arrhythmia). This disorder is a form of long QT syndrome, which is a heart condition that causes the heart (cardiac) muscle to take longer than usual to recharge between beats. The term "long QT" refers to a specific pattern of heart activity that is detected with an electrocardiogram (ECG or EKG), which is a test used to measure the electrical activity of the heart. In people with long QT syndrome, the part of the heartbeat known as the QT interval is abnormally long. Abnormalities in the time it takes to recharge the heart lead to abnormal heart rhythms.

MalaCards based summary : Long Qt Syndrome 1, also known as romano-ward syndrome, is related to long qt syndrome 3 and long qt syndrome 2, and has symptoms including syncope An important gene associated with Long Qt Syndrome 1 is KCNQ1 (Potassium Voltage-Gated Channel Subfamily Q Member 1), and among its related pathways/superpathways are Developmental Biology and Circadian entrainment. The drugs Racepinephrine and Epinephrine have been mentioned in the context of this disorder. Affiliated tissues include heart, testes and prostate, 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 KCNQ1 gene on chromosome 11p15.5-p15.4.

NIH Rare Diseases : 53 Romano-Ward syndrome is the most common form of inheritedlong QT syndrome. Symptoms include arrhythmia, fainting, cardiac arrest, and sudden death. There are six different types of this syndrome, long QT 1 through 6. Each type is caused by a change in a different gene. The most prevalent form of long QT syndrome is long QT type 1. Long QT type 1 is caused by changes in the KCNQ1 gene. Romano-Ward syndrome is inherited in an autosomal dominant fashion.

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). A form of torsade de pointes in which the first beat has a short coupling interval has been described (613600). (192500)

UniProtKB/Swiss-Prot : 75 Long QT syndrome 1: 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.

Wikipedia : 76 Long QT syndrome (LQTS) is a condition which affects repolarization of the heart after a heartbeat. This... more...
