    ### Instruction:
    What are the genetic changes related to familial paroxysmal kinesigenic dyskinesia ?
    ### Response:
    Familial paroxysmal kinesigenic dyskinesia can be caused by mutations in the PRRT2 gene. The function of the protein produced from this gene is unknown, although it is thought to be involved in the development and function of the brain. Studies suggest that the PRRT2 protein interacts with a protein that helps control signaling between nerve cells (neurons).
