KCNH2‐L693P Causes Long QT Syndrome Type 2 Through hERG Channel Dysfunction: Functional Validation of a Variant of Uncertain Significance [PDF]
Background Congenital long QT syndrome (LQTS) is an inherited arrhythmia characterized by QT prolongation and increased risk of ventricular arrhythmias. Type 2 LQTS (LQT2) results from mutations in the KCNH2 gene encoding the hERG potassium channel. With

Congenital Long QT Syndrome with Compound Mutations in KCNH2 Gene
Congenital long QT syndrome is a genetic disorder encompassing a family of mutations that can lead to aberrant ventricular electrical activity. We report on two brothers with long QT syndrome caused by compound mutations in the KCNH2 gene inherited from parents who had no prolonged QT interval on electrocardiography.

Circulating KCNH2 current-activating factor in patients with heart failure and ventricular tachyarrhythmia. [PDF]
It is estimated that approximately half of the deaths in patients with HF are sudden and that the most likely causes of sudden death are lethal ventricular tachyarrhythmias such as ventricular tachycardia (VT) or fibrillation (VF).

Kcnh2 mediates FAK/AKT‐FOXO3A pathway to attenuate sepsis‐induced cardiac dysfunction [PDF]
AbstractObjectivesMyocardial dysfunction is a significant manifestation in sepsis, which results in high mortality. Even Kcnh2 has been hinted to associate with the pathological process, its involved signalling is still elusive.Materials and methodsThe caecal ligation puncture (CLP) surgery or lipopolysaccharide (LPS) injection was performed to induce ...

Neonatal death of siblings with Uhl’s disease and KCNH2 mutation - A rare association
ABSTRACT Uhl’s disease is a rare disorder secondary to the uncontrolled destruction of right ventricular myocytes during the perinatal period. We present here the case of a 1-month-old child who died suddenly of Uhl’s disease, which was only diagnosed at autopsy and histological examination.

Identification and characterization of two novel KCNH2 mutations contributing to long QT syndrome.
We identified two different inherited mutations in KCNH2 gene, or human ether-a-go-go related gene (hERG), which are linked to Long QT Syndrome. The first mutation was in a 1-day-old infant, whereas the second was in a 14-year-old girl.

Síndrome de QT largo: Nueva mutación en el gen KCNH2
Se presenta el caso de un paciente masculino de 10 años, con cuadro clínico y electrocardiográfico concordante con síndrome de QT largo, en quien se realizó secuenciación de los genes KCNQ1 (LQT1), KCNH2 (LQT2), SCN5A (LQT3), KCNE1 (LQT5), KCNE2 (LQT6 ...

KCNH2 regulates the growth and metastasis of pancreatic cancer
Objective:. Due to the characteristics of insidious onset and early metastasis of pancreatic cancer (PC), patients are often diagnosed at an advanced stage and often delayed in completing surgical resection timely, resulting in poor prognosis. Therefore,
