What is the official name of the FBLN5 gene?
The official name of this gene is “fibulin 5.”
FBLN5 is the gene's official symbol. The FBLN5 gene is also known by other names, listed below.

What is the normal function of the FBLN5 gene?
The FBLN5 gene provides instructions for making a protein called fibulin-5. This protein is part of a group of proteins called fibulins. Fibulins have a variety of functions in the extracellular matrix, which is the intricate lattice of proteins and other molecules that forms in the spaces between cells.
In the extracellular matrix, fibulin-5 appears to play a critical role in the assembly of elastic fibers. These slender bundles of proteins provide strength and flexibility to connective tissue (tissue that supports the body's joints and organs). Fibulin-5 is found in tissues and organs that are rich in elastic fibers, including developing arteries and the heart valves, lungs, and skin.
How are changes in the FBLN5 gene related to health conditions?
Genetics Home Reference provides information about age-related macular degeneration, which is also associated with changes in the FBLN5 gene.
Where is the FBLN5 gene located?
Cytogenetic Location: 14q32.1
Molecular Location on chromosome 14: base pairs 91,869,411 to 91,947,702
(Homo sapiens Annotation Release 107, GRCh38.p2) (
The FBLN5 gene is located on the long (q) arm of chromosome 14 at position 32.1.
More precisely, the FBLN5 gene is located from base pair 91,869,411 to base pair 91,947,702 on chromosome 14.
