Mutations in the delayed rectifier K+ channel subunit KvLQT1 have been identified as responsible for both Romano-Ward (RW) and Jervell and Lange-Nielsen (JLN) inherited long QT syndromes. We report the molecular cloning of a human KvLQT1 isoform that is expressed in several human tissues including heart. Expression studies revealed that the...

We report the functional expression of four KCNQ1 mutations affecting arginine residues and resulting in Romano-Ward (RW) and the Jervell and Lange-Nielsen (JLN) congenital long QT syndromes.

The Jervell and Lange-Nielsen (JLN) syndrome (MIM 220400) is an inherited autosomal recessive disease characterized by a congenital bilateral deafness associated with a QT prolongation on the electrocardiogram, syncopal attacks due to ventricular arrhythmias and a high risk of sudden death. JLN syndrome is a rare disease, which seems to affect...
