FUNCTION: [Summary is not available for the mouse gene. This summary is for the human ortholog.] This gene belongs to the TMEM43 family. Defects in this gene are the cause of familial arrhythmogenic right ventricular dysplasia type 5 (ARVD5), also known as arrhythmogenic right ventricular cardiomyopathy type 5 (ARVC5). Arrhythmogenic right ventricular dysplasia is an inherited disorder, often involving both ventricles, and is characterized by ventricular tachycardia, heart failure, sudden cardiac death, and fibrofatty replacement of cardiomyocytes. This gene contains a response element for PPAR gamma (an adipogenic transcription factor), which may explain the fibrofatty replacement of the myocardium, a characteristic pathological finding in ARVC.

PHENOTYPE: In a gihg-throughput screen, female homozygous mutant mice exhibited an increased anxiety-like response during open field activity testing when compared with their gender-matched wild-type littermates and the historical mean. [provided by MGI curators]
