    ### Instruction:
    What are the genetic changes related to auriculo-condylar syndrome ?
    ### Response:
    Auriculo-condylar syndrome can be caused by mutations in either the GNAI3 or PLCB4 gene. These genes provide instructions for making proteins that are involved in chemical signaling within cells. They help transmit information from outside the cell to inside the cell, which instructs the cell to grow, divide, or take on specialized functions.
