NCI: Human KCNQ1 wild-type allele is located in the vicinity of 11p15.5 and is approximately 404 kb in length. This allele, which encodes potassium voltage-gated channel subfamily KQT member 1 protein, plays a role in the regulation of both cardiac repolarization and potassium transport. Mutations in the gene are associated with hereditary long QT syndrome, Romano-Ward syndrome, Jervell and Lange-Nielsen syndrome and familial atrial fibrillation. (Entrez Gene)
