Overview

Andersen-Tawil syndrome (ATS) is a very rare syndrome which is characterized by periodic paralysis, arrhythmias and long QT interval. Ellen Andersen was the first to describe the Andersen-Tawil syndrome (ATS) in 1971.

In 1971, Ellen Andersen et al was the first to report the symptoms of the syndrome which includes short stature, hypertelorism, broad nasal root, mandibular hypoplasia, scaphocephaly, and clinodactyly in an 8 year old boy.^[1]^[2]
In 1976, Stubbs described bidirectional ventricular tachycardia in a women.
In 1977, Sansone et al reported the symptoms of periodic paralysis, ventricular arrhythmia in a patient.
In 1994, Tawil gave the name Andersen syndrome for a clinical triad which consists of periodic paralysis, ventricular ectopy, and dysmorphic features.
In 1994, Tawil made a significant contributions to the understanding that Andersen's syndrome is different from other long QT syndrome demonstrating lack of genetic linkage.^[3]
In 2002, Andelfinger et al identified missense mutation in KCNJ2 gene were first implicated in the pathogenesis of Andersen-Tawil syndrome.
