    What are the genetic changes related to rapid-onset dystonia parkinsonism ?
    ### Response:
    Rapid-onset dystonia parkinsonism is caused by mutations in the ATP1A3 gene. This gene provides instructions for making one part of a larger protein called Na+/K+ ATPase, also known as the sodium pump. This protein is critical for the normal function of nerve cells (neurons) in the brain.
