What is the official name of the SPG7 gene?
The official name of this gene is “spastic paraplegia 7 (pure and complicated autosomal recessive).”
SPG7 is the gene's official symbol. The SPG7 gene is also known by other names, listed below.

What is the normal function of the SPG7 gene?
The SPG7 gene provides instructions for producing a protein called paraplegin, which is a member of the AAA protein family. This protein family plays a role in many cellular activities, including regulation of cell components and proteins. Located within the inner membrane of the energy-producing centers of cells (mitochondria), paraplegin is one of the proteins that form a complex called the m-AAA protease. The m-AAA protease is responsible for assembling ribosomes (cellular structures that process the cell's genetic instructions to create proteins) and removing nonfunctional proteins in the mitochondria.
