    Is X-linked infantile spasm syndrome inherited ?
    ### Response:
    X-linked infantile spasm syndrome can have different inheritance patterns depending on the genetic cause.  When caused by mutations in the ARX gene, this condition is inherited in an X-linked recessive pattern. The ARX gene is located on the X chromosome, which is one of the two sex chromosomes.
