Overview

Andersen-Tawil syndrome is a type of long QT syndrome and is also considered a rare form of periodic paralysis. It causes episodes of muscle weakness, changes in heart rhythm (arrhythmia), and developmental abnormalities. Physical abnormalities associated with this condition typically affect the head, face, and limbs. There are two different types of Andersen-Tawil syndrome. Type 1 is caused by changes in the KCNJ2 gene, while the cause of type 2 is not yet known. Andersen-Tawil syndrome is inherited in an autosomal dominant pattern.[1]
