    Is McCune Albright syndrome inherited ?
    ### Response:
    Is McCune Albright syndrome inherited? McCune Albright syndrome (MAS) is not inherited. It is caused by a random change (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.
