What is the normal function of the CISD2 gene?
The CISD2 gene provides instructions for making a protein that is found in the outer membrane of cell structures called mitochondria. Mitochondria are involved in a wide variety of cellular activities, including energy production, chemical signaling, and regulation of cell growth and division. The exact function of the CISD2 protein is unknown, but it is thought to help keep mitochondria functioning normally.
How are changes in the CISD2 gene related to health conditions?
