What is the official name of the TAZ gene?
The official name of this gene is “tafazzin.”
TAZ is the gene's official symbol. The TAZ gene is also known by other names, listed below.

What is the normal function of the TAZ gene?
The TAZ gene provides instructions for producing a protein called tafazzin. Several different versions (isoforms) of the tafazzin protein are produced from the TAZ gene. Most isoforms are found in all tissues, but some are found only in certain types of cells. Tafazzin is located in structures called mitochondria, which are the energy-producing centers of cells. Tafazzin is involved in altering a fat (lipid) called cardiolipin, which plays critical roles in the mitochondrial inner membrane. Tafazzin adds a fatty acid called linoleic acid to the cardiolipin molecule, which enables cardiolipin to perform its functions. Cardiolipin is necessary for maintaining mitochondrial shape, energy production, and protein transport within cells.
How are changes in the TAZ gene related to health conditions?
Genetics Home Reference provides information about familial dilated cardiomyopathy, which is also associated with changes in the TAZ gene.
Where is the TAZ gene located?
Cytogenetic Location: Xq28
Molecular Location on the X chromosome: base pairs 154,411,518 to 154,421,726
(Homo sapiens Annotation Release 107, GRCh38.p2) (
The TAZ gene is located on the long (q) arm of the X chromosome at position 28.
More precisely, the TAZ gene is located from base pair 154,411,518 to base pair 154,421,726 on the X chromosome.
