    ### Instruction:
    Is McCune-Albright syndrome inherited ?
    ### Response:
    McCune-Albright syndrome is not inherited. Instead, it is caused by a random mutation in the GNAS gene that occurs very early in development. As a result, some of the body's cells have a normal version of the GNAS gene, while other cells have the mutated version.
