  • Title: Ankyrin-B syndrome: a case of sinus node dysfunction, atrial fibrillation and prolonged QT in a young adult.
    Author: Robaei D, Ford T, Ooi SY.
    Journal: Heart Lung Circ; 2015 Feb; 24(2):e31-4. PubMed ID: 25456501.
    Abstract:
    Ankyrin-B protein is involved in regulating expression and localisation of cardiac ion channels and transporters. Mutations of the ANK2 gene in the rare condition Ankyrin-B syndrome result in loss of function of the ankyrin-B protein which in turn leads to abnormal regulation of intracellular sodium and calcium and a predisposition to cardiac arrhythmia including torsades de pointes. We describe a rare case of this condition characterised by sinus node dysfunction, atrial fibrillation and prolonged QT syndrome in a young patient with a family history of sudden death. The management of Ankyrin-B syndrome may include avoidance of QT prolonging medications, insertion of a permanent pacemaker for sinus node dysfunction, or a cardioverter defibrillator for those at high-risk of sudden death from torsades de pointes.
