Tafazzin is a protein highly expressed in cardiac and skeletal muscle. It may be involved in the metabolism of cardiolipin.

[edit] Pathology
The mutation of the tafazzin gene is associated with a number of clinical disorders including Barth syndrome (BTHS) (type II 3-Methylglutaconic aciduria), dilated cardiomyopathy (DCM), hypertrophic DCM, endocardial fibroelastosis, and left ventricular noncompaction (LVNC). Tafazzin is a phospholipid cardiolipin (CL) (Neuwald, 1997), the signature lipid of the mitochondrial inner membrane. As a result, BTHS patients exhibit defects in CL metabolism, including aberrant CL fatty acyl composition, accumulation of monolysocardiolipin (MLCL) and reduced total CL levels (Vreken et al., 2000; Valianpour et al., 2005)
[edit] History
The protein was identified by Italian scientists Silvia Bione et al. in 1996.[1] Owing to the complex procedure required for the identification of tafazzin, the protein was named after "Tafazzi", a masochistic comic character in an Italian television sports show.
