Official Full Name: transmembrane protein 43
Also known as: LUMA; ARVC5; ARVD5; AUNA3; EDMD7; EDMD7; AUNA2
This gene belongs to the TMEM43 family. Defects in this gene are responsible for familial arrhythmic right ventricular dysplasia type 5 (ARVD5), also known as arrhythmic right ventricular cardiomyopathy type 5 (ARVC5). Arrhythmic right ventricular dysplasia is an inherited disorder, often involving both ventricles, characterized by ventricular tachycardia, heart failure, sudden cardiac death, and fibrofatty replacement of cardiomyocytes. This gene contains a response element for PPARγ, an adipogenic transcription factor, which may explain fibrofatty replacement of the myocardium, a characteristic pathological finding in ARVC.
