Two Families of Andersen's Syndrome with Cardiac Arrhythmia, Periodic Paralysis, and KCNJ2 Gene Mutations

Andersen's syndrome is a rare autosomal dominant disorder characterized by periodic paralysis, dysmorphic features and cardiac arrhythmias. This syndrome is known to be a type of potassium channelopathies with a mutation in the KCNJ2 (Kir2.1) gene. Here, we present two families with genetically confirmed Andersen’s syndrome through clinical and electrophysiological findings. They showed all features of the triad, and one of them had a novel mutation c.307G>A (Met307Ile). J Korean Neurol Assoc 24(3):265-269, 2006
