    ### Instruction:
    What are the genetic changes related to 3MC syndrome ?
    ### Response:
    3MC syndrome is caused by mutations in the COLEC11 or MASP1 gene. These genes provide instructions for making proteins that are involved in a series of reactions called the lectin complement pathway. This pathway is thought to help direct the movement (migration) of cells during early development before birth to form the organs and systems of the body.
