Below is an instruction from Human. Write a response.
    ### Instruction:
    What are the genetic changes related to trichohepatoenteric syndrome ?
    ### Response:
    Trichohepatoenteric syndrome can be caused by mutations in the TTC37 or SKIV2L gene. These genes provide instructions for making proteins whose functions have not been confirmed. Researchers speculate that they work together with other proteins within cells to help recognize and break down excess or abnormal messenger RNA (mRNA) molecules.
