Overview
If left untreated, patients with Andersen-Tawil syndrome may progress to develop periodic paralysis, cardiac arrhythmias and can lead to the death of the patient. Common complications of Andersen-Tawil syndrome include neuromuscular symptoms and malignant hyperthermia. Prognosis is generally range from good to poor.
Natural History, Complications, and Prognosis
Natural History
- The symptoms of Andersen-Tawil syndrome usually develop in the first decade of life, and start with symptoms such as episodic flaccid muscle weakness, ventricular arrhythmias and prolonged QT interval.[1][2]
- If left untreated, patients with Andersen-Tawil syndrome may progress to develop cardiac arrhythmias and can lead to the death of the patient.
Complications
- Common complications of Andersen-Tawil syndrome include:[3][4][5][6][7][8]
- Syncope or presyncopal attacks
- Exercise-induced nonsustained bidirectional ventricular tachycardia
- QT or QU prolongation with polymorphic ventricular tachycardia which are life-threatening
- Sudden cardiac death
- Neurological or neurocognitive defects
Prognosis
- Prognosis is generally range from good to poor, based on the severity of the mutation on KCNJ2 gene.
