    ### Instruction:
    What are the genetic changes related to DOORS syndrome ?
    ### Response:
    DOORS syndrome can be caused by mutations in the TBC1D24 gene. This gene provides instructions for making a protein whose specific function in the cell is unclear. Studies suggest the protein may have several roles in cells. The TBC1D24 protein belongs to a group of proteins that are involved in the movement (transport) of vesicles, which are small sac-like structures that transport proteins and other materials within cells.
