Arrhythmogenic right ventricular cardiomyopathy
How does arrhythmogenic right ventricular cardiomyopathy run in families?
Up to half of all cases of arrhythmogenic right ventricular cardiomyopathy (ARVC) appear to run in families. Most familial cases of the disease have an autosomal dominant pattern of inheritance, which means one copy of an altered gene in each cell is sufficient to cause the disorder.
Rarely, ARVC has an autosomal recessive pattern of inheritance, which means both copies of a gene in each cell have mutations. The parents of an individual with an autosomal recessive condition each carry one copy of the mutated gene, but they typically do not show signs and symptoms of the condition.
