Normal Function
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.
Health Conditions Related to Genetic Changes
Spastic paraplegia type 11
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.
