    ### Instruction:
    What are the genetic changes related to Tietz syndrome ?
    ### Response:
    Tietz syndrome is caused by mutations in the MITF gene. This gene provides instructions for making a protein that plays a role in the development, survival, and function of certain types of cells. Molecules of the MITF protein attach (bind) to each other or with other proteins that have a similar structure, creating a two-protein unit (dimer).
