Molecular assay reagents intended to identify mutations in the potassium voltage-gated channel, KQT-like subfamily, member 1 (KCNQ1) gene, located at chromosome 11p15.5, which encodes for a protein involved in potassium-channel formation and function and helps move potassium out of the cell. Mutations at this locus have been identified in patients with familial atrial fibrillation, JLNS, Romano-Ward syndrome, and short QT syndromes.
