(G;G) 0 common in clinvar

This is a genotype with recommended actions if clinically confirmed. In brief:

  • Arrhythmogenic right ventricular dysplasia or cardiomyopathy (ARVD) is characterized by structural and functional abnormalities of the right ventricle.
  • Mutations in the DSC2, DSG2, DSP, PKP2 and TMEM43 genes may lead to ARVD.
  • Antiarrhythmic medication (such as beta-blockers) may be used to prevent ventricular arrhythmias.
  • Implantable cardioverter defibrillators (ICD) can be effective for the prevention of SCD in ARVD patients with extensive disease.
  • Electrophysiological (EP) testing might be useful for risk assessment of sudden cardiac death (SCD) in patients with ARVD.
  • Annual clinical screening for cardiomyopathy is recommended from ages 10 - 50 in asymptomatic individuals known to carry a disease-causing mutation(s) or at any time that signs or symptoms appear.
  • Both autosomal dominant and recessive forms of ARVD are possible; ARVD patients carrying more than one disease-associated mutation may show a more severe phenotype characterized by a younger age of onset and worse prognosis.
