What is the official name of the ELOVL4 gene?
The official name of this gene is “ELOVL fatty acid elongase 4.”
ELOVL4 is the gene's official symbol. The ELOVL4 gene is also known by other names, listed below.

What is the normal function of the ELOVL4 gene?
The ELOVL4 gene provides instructions for making a protein that is found primarily in the retina, the specialized light-sensitive tissue that lines the back of the eye. Within the retina, the ELOVL4 protein is produced in specialized light receptor cells (photoreceptors). The ELOVL4 protein is also found in the brain and skin, but less is known about its activity (expression) in these structures.
Inside photoreceptor cells, this protein is located in a cell structure called the endoplasmic reticulum that is involved in protein production, processing, and transport. The ELOVL4 protein plays a role in making a group of fats called very long-chain fatty acids. The protein helps add carbon molecules to long-chain fatty acids, making them very long-chain fatty acids. The function of the very long-chain fatty acids produced by the ELOVL4 protein is unknown.
How are changes in the ELOVL4 gene related to health conditions?
Genetics Home Reference provides information about age-related macular degeneration, which is also associated with changes in the ELOVL4 gene.
Where is the ELOVL4 gene located?
Cytogenetic Location: 6q14
Molecular Location on chromosome 6: base pairs 79,914,812 to 79,947,598
(Homo sapiens Annotation Release 107, GRCh38.p2) (
The ELOVL4 gene is located on the long (q) arm of chromosome 6 at position 14.
More precisely, the ELOVL4 gene is located from base pair 79,914,812 to base pair 79,947,598 on chromosome 6.
