Overview

There is insufficient evidence to recommend routine screening for Andersen-Tawil syndrome.

Screening

  • There is insufficient evidence to recommend routine screening for Andersen-Tawil syndrome.
  • But when a patient with positive KCNJ2 mutation and have no symptoms in Andersen-Tawil syndrome yearly screening with the following should be considered:
    • A 12-lead ECG[1][2][3]
    • 24-hour Holter monitoring
