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

What is the normal function of the ELN gene?
The ELN gene provides instructions for making a protein called tropoelastin. Multiple copies of the tropoelastin protein attach to one another and are processed to form a mature protein called elastin. Elastin is the major component of elastic fibers, which are slender bundles of proteins that provide strength and flexibility to connective tissue (tissue that supports the body's joints and organs). Elastic fibers are found in the intricate lattice that forms in the spaces between cells (the extracellular matrix), where they give structural support to organs and tissues such as the heart, skin, lungs, ligaments, and blood vessels.
How are changes in the ELN gene related to health conditions?
Where is the ELN gene located?
Cytogenetic Location: 7q11.23
Molecular Location on chromosome 7: base pairs 74,027,772 to 74,069,907

The ELN gene is located on the long (q) arm of chromosome 7 at position 11.23.
More precisely, the ELN gene is located from base pair 74,027,772 to base pair 74,069,907 on chromosome 7.
