The product of this gene belongs to the potassium channel KCNE family. Potassium ion channels are essential to many cellular functions and show a high degree of diversity, varying in their electrophysiologic and pharmacologic properties. This gene encodes a transmembrane protein known to associate with the product of the KVLQT1 gene to form the delayed rectifier potassium channel. Mutation in this gene are associated with both Jervell and Lange-Nielsen and Romano-Ward forms of long-QT syndrome. Alternatively spliced transcript variants encoding the same protein have been identified. [provided by RefSeq, Jul 2008]
A study in the Chinese Han population demonstrated that molecular analysis of the KCNE1 gene identified a novel missense mutation (F54V) in one Sudden Unexplained Nocturnal Death Syndrome (SUNDS) case, which was absent in healthy controls, suggesting it as a potential pathogenic cause for that specific case [Liu et al. DOI:10.1016/j.forsciint.2013.04.020]. A study in humans identified numerous differentially expressed genes in blood from myocardial infarction patients, including the KCNE1 as a potential MI biomarker mentioned in the introduction and discussion [Zhao et al. DOI:10.3892/etm.2017.5580].
