Arrhythmogenic right ventricular dysplasia causes

Jump to navigation Jump to search

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:

  • 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
