arrhythmogenic right ventricular dysplasia type 5

An autosomal dominant disorder (OMIM:604400) characterised by fibrofatty degeneration of the right ventricular myocardium (especially the free wall), electrical lability and sudden death. It is clinically defined by EKG/ECG and angiographic criteria.

Molecular pathology
Defects of TMEM43, which encodes a protein thought to play a key role in maintaining nuclear envelope structure, cause arrhythmogenic right ventricular dysplasia type 5.
