Below is an instruction from Human. Write a response.
    ### Instruction:
    What are the genetic changes related to distal hereditary motor neuropathy, type II ?
    ### Response:
    Mutations in the HSPB1 and HSPB8 genes cause distal hereditary motor neuropathy, type II. These genes provide instructions for making proteins called heat shock protein beta-1 and heat shock protein beta-8. Heat shock proteins help protect cells under adverse conditions such as infection, inflammation, exposure to toxins, elevated temperature, injury, and disease.
