What is the normal function of the GDAP1 gene?
The GDAP1 gene provides instructions for making a protein called ganglioside-induced differentiation-associated protein 1. This protein is found in the outer membrane of mitochondria, the energy-producing centers within cells. Mitochondria are dynamic structures that change shape through processes called fission (splitting into smaller pieces) and fusion (combining pieces). Changes in shape are thought to be critical for mitochondria to work properly. Although the function of the GDAP1 protein is not well understood, it appears to play a role in controlling the shape of mitochondria by promoting fission.
How are changes in the GDAP1 gene related to health conditions?
Where is the GDAP1 gene located?
