Experimental mapping of the canine KCNJ2 and KCNJ12 gene structures and functional analysis of the canine KIR2.2 ion channel [PDF]
For many model organisms traditionally in use for cardiac electrophysiological studies, characterization of ion channel genes is lacking. We focused here on two genes encoding the inward rectifier current, KCNJ2 and KCNJ12, in the dog heart.

Phenotypic Variability of Andersen–Tawil Syndrome Due to Allelic Mutation c.652C>T in the KCNJ2 Gene—A New Family Case Report [PDF]
Andersen–Tawil syndrome (ATS) is a multisystem channelopathy characterized by periodic paralysis, ventricular arrhythmias, prolonged QT interval, and facial dysmorphisms occurring in the first/second decade of life.

Expression of a Mutant kcnj2 Gene Transcript in Zebrafish. [PDF]
Long QT 7 syndrome (LQT7, also known as Andersen-Tawil syndrome) is a rare autosomal-dominant disorder that causes cardiac arrhythmias, periodic paralysis, and dysmorphic features. Mutations in the human KCNJ2 gene, which encodes for the subunit of the potassium inwardly-rectifying channel (IK1), have been associated with the disorder.

Patients with Dilated Cardiomyopathy and Sustained Monomorphic Ventricular Tachycardia Show Up-Regulation of KCNN3 and KCNJ2 Genes and CACNG8-Linked Left Ventricular Dysfunction. [PDF]
Disruptions in cardiac ion channels have shown to influence the impaired cardiac contraction in heart failure. We sought to determine the altered gene expression profile of this category in dilated cardiomyopathy (DCM) patients and relate the altered ...

Mutations of KCNJ2 gene associated with Andersen–Tawil syndrome in Korean families [PDF]
Mutations of the KCNJ2 gene are a major underlying cause of Andersen-Tawil syndrome (ATS), a rare autosomal dominant inherited disorder that is characterized by periodic paralysis, cardiac arrhythmias, and developmental dysmorphic features. The KCNJ2 gene encodes an inward rectifying K(+) channel protein, Kir2.1, which plays an important role in ...

Characterization of Loss-Of-Function KCNJ2 Mutations in Atypical Andersen Tawil Syndrome
Andersen-Tawil Syndrome (ATS) is a rare disease defined by the association of cardiac arrhythmias, periodic paralysis and dysmorphic features, and is caused by KCNJ2 loss-of-function mutations.

Novel mutation in KCNJ2 gene causes long QT interval syndrome type 7 and learning disability: A case report. [PDF]
Rationale: Long QT interval syndrome type 7 (LQT7) is a rare hereditary multisystem disorder characterized by a classic triad of ventricular arrhythmias with QT interval prolongation, periodic paralysis, and distinctive skeletal and facial features. The Kir2.1 protein is encoded by the KCNJ2 gene, which has been associated with

Novel mutation in the KCNJ2 gene is associated with a malignant arrhythmic phenotype of Andersen-Tawil syndrome. [PDF]
BackgroundAndersen‐Tawil syndrome (ATS) is a rare inherited multisystem disorder associated with mutations in KCNJ2 and low prevalence of life‐threatening ventricular arrhythmias. Our aim was to describe the clinical course of ATS in a family, in which the proband survived aborted cardiac arrest (ACA) and genetic screening revealed a previously unknown
