    ### Instruction:
    What are the genetic changes related to mitochondrial membrane protein-associated neurodegeneration ?
    ### Response:
    Mutations in the C19orf12 gene cause MPAN. The protein produced from this gene is found in the membrane of cellular structures called mitochondria, which are the energy-producing centers of the cell. Although its function is unknown, researchers suggest that the C19orf12 protein plays a role in the maintenance of fat (lipid) molecules, a process known as lipid homeostasis.
