What is the official name of the SPG11 gene?

The official name of this gene is “spastic paraplegia 11 (autosomal recessive).”

SPG11 is the gene's official symbol. The SPG11 gene is also known by other names, listed below.

What is the normal function of the SPG11 gene?

The SPG11 gene provides instructions for making the protein spatacsin. Spatacsin is active (expressed) throughout the nervous system, although its exact function is unknown. Researchers speculate that it may help control the activity of particular genes (gene expression) or play a role in the transport (trafficking) of proteins. Spatacsin may also be involved in the maintenance of axons, which are specialized extensions of nerve cells (neurons) that transmit impulses throughout the nervous system.

How are changes in the SPG11 gene related to health conditions?

spastic paraplegia type 11 - caused by mutations in the SPG11 gene

More than 65 mutations in the SPG11 gene have been found to cause spastic paraplegia type 11. Most of these mutations change the structure of the spatacsin protein. The effect that the altered spatacsin protein has on the nervous system is not known. Researchers suggest that mutations in spatacsin may cause the signs and symptoms of spastic paraplegia type 11 by interfering with the protein's proposed role in the maintenance of axons.

Genetics Home Reference provides information about amyotrophic lateral sclerosis, which is also associated with changes in the SPG11 gene.

Where is the SPG11 gene located?

Cytogenetic Location: 15q14

Molecular Location on chromosome 15: base pairs 44,562,696 to 44,663,678

(Homo sapiens Annotation Release 107, GRCh38.p2) (NCBIThis link leads to a site outside Genetics Home Reference.)

The SPG11 gene is located on the long (q) arm of chromosome 15 at position 14.

The SPG11 gene is located on the long (q) arm of chromosome 15 at position 14.

More precisely, the SPG11 gene is located from base pair 44,562,696 to base pair 44,663,678 on chromosome 15.
