About This Section Entrez Gene summary for KCNQ1 : This gene encodes a voltage-gated potassium channel required for repolarization phase of the cardiac action potential. This protein can form heteromultimers with two other potassium channel proteins, KCNE1 and KCNE3. Mutations in this gene are associated with hereditary long QT syndrome 1 (also known as Romano-Ward syndrome), Jervell and Lange-Nielsen syndrome, and familial atrial fibrillation. This gene exhibits tissue-specific imprinting, with preferential expression from the maternal allele in some tissues, and biallelic expression in others. This gene is located in a region of chromosome 11 amongst other imprinted genes that are associated with Beckwith-Wiedemann syndrome (BWS), and itself has been shown to be disrupted by chromosomal rearrangements in patients with BWS. Alternatively spliced transcript variants have been found for this gene. (provided by RefSeq, Aug 2011) UniProtKB/Swiss-Prot: KCNQ1_HUMAN, P51787 Function : Probably important in cardiac repolarization. Associates with KCNE1 (MinK) to form the I(Ks) cardiacpotassium current. Elicits a rapidly activating, potassium-selective outward current. Muscarinic agonist oxotremorine-M strongly suppresses KCNQ1/KCNE1 current in CHO cells in which cloned KCNQ1/KCNE1 channels were coexpressed with M1 muscarinic receptors. May associate also with KCNE3 (MiRP2) to form the potassium channel that is important for cyclic AMP-stimulated intestinal secretion of chloride ions, which is reduced in cystic fibrosis and pathologically stimulated in cholera and other forms of secretory diarrhea summary
for KCNQ1 : Voltage-gated potassium channels (KV) belong to the 6-TM family of potassium channel that also comprises theCa2+-activated Slo (actually 7-TM) and the Ca2+-activated SK subfamilies. The pore-forming alpha-subunitscontain a single pore-forming region and combine to form tetramers. Heteromeric channels can be formedwithin subfamilies e.g. KV1.1 with KV1.2 and KCNQ2 with KCNQ3. Gene Wiki entry for KCNQ1 (KvLQT1) fRNAdb sequence ontologies for KCNQ1 - the ORGUL cluster for this gene includes several descriptions: transcript - An RNA synthesized on a DNA or RNA template by an RNA polymerase.mature_transcript - A transcript which has undergone the necessary modifications, if any, for its function. In eukaryotes this includes, for example, processing of introns, cleavage, base modification, and modifications to the 5' and/or the 3' ends, other than addition of bases. In bacteria functional mRNAs are usually not modified.

KCNQ1 for disorders About GeneDecksing OMIM gene information: 607542 604115 OMIM disorders : 192500 220400 607554 609621 UniProtKB/Swiss-Prot: KCNQ1_HUMAN, P51787
Defects in KCNQ1 are the cause of long QT syndrome type 1 (LQT1) [MIM:192500]; also known as Romano-Ward syndrome (RWS). Long QT syndromes are heart disorders 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. LQT1 inheritance is an autosomal dominant Defects in KCNQ1 are the cause of Jervell and Lange-Nielsen syndrome type 1 (JLNS1) [MIM:220400]. JLNS1 is an autosomal recessive disorder characterized by congenital deafness, prolongation of the QT interval, syncopal attacks due to ventricular arrhythmias, and a high risk of sudden death Defects in KCNQ1 are the cause of familial atrial fibrillation type 3 (ATFB3) [MIM:607554]. Atrial fibrillation is a common disorder of cardiac rhythm that is hereditary in a small subgroup of patients. It is characterized by disorganized atrial electrical activity and ineffective atrial contraction promoting blood stasis in the atria and reduces ventricular filling. It can result in palpitations, syncope, thromboembolic stroke, and congestive heart failure Defects in KCNQ1 are the cause of short QT syndrome type 2 (SQT2) [MIM:609621]. Short QT syndromes are heart disorders characterized by idiopathic persistently and uniformly short QT interval on ECG in the absence of structural heart disease in affected individuals. They cause syncope and sudden death 20/40 diseases for KCNQ1 (see all 40 ): About MalaCards jervell-lange nielsen syndrome long qt syndrome 1 beckwith-wiedemann syndrome long qt syndrome atrial fibrillation familial atrial fibrillation long qt syndrome 1, acquired short qt syndrome 2 subclavian steal syndrome short qt syndrome sudden infant death syndrome heart block secretory diarrhea congenital heart block type 2 diabetes mellitus cystic fibrosis diabetes mellitus brugada syndrome hearing loss hyperparathyroidism 6 diseases from the University of Copenhagen DISEASES database for KCNQ1 :Long QT syndrome Beckwith-Wiedemann syndrome Congenital heart block Timothy syndrome Heart disease Sudden infant death syndrome 10/26 Novoseek disease relationships for KCNQ1 gene (see all 26 ) About this table
