Overview

Arrhythmogenic right ventricular cardiomyopathy is typically inherited as an autosomal dominant pattern with variable penetrance and incomplete expression. Approximately 40% to 50% of ARVC/D patients have a mutation in genes encoding a desmosome protein. The gene is on the chromosome 14q23-q24.There is an autosomal recessive trait variant associated with palmoplantar keratosis and wooly hair named Naxos disease.


Causes

Arrhythmogenic right ventricular cardiomyopathy is cause by genetic inheritance as:[1][2]

  • An autosomal dominant pattern with variable penetrance and incomplete expression.
  • A mutation in genes encoding a desmosome protein ( 40% to 50% of ARVC/D patients)
  • The gene is on the chromosome 14q23-q24
  • There is an autosomal recessive trait variant associated with palmoplantar keratosis and wooly hair named Naxos disease
