    What is the outlook for Aicardi-Goutieres Syndrome Disorder ?
    ### Response:
    The prognosis depends upon the severity of symptoms. Children with early-onset AGS have the highest risk of death. Children with the later-onset form may be left with weakness or stiffness in the peripheral muscles and arms, weak muscles in the trunk of the body, and poor head control.
