Molecular assay reagents intended to identify mutations in the potassium voltage-gated channel, Isk-related family, member 1 (KCNE1) gene, located at chromosome 21q22.1-q22.2, which is involved in the formation and activation of potassium ion channels in cells. Mutations at this locus have been identified in patients with Jervell and Lange-Nielsen Syndrome (JLNS), a long QT Syndrome.
