    ### Instruction:
    What are the genetic changes related to Proteus syndrome ?
    ### Response:
    Proteus syndrome results from a mutation in the AKT1 gene. This genetic change is not inherited from a parent; it arises randomly in one cell during the early stages of development before birth. As cells continue to grow and divide, some cells will have the mutation and other cells will not.
