    Is glycogen storage disease type IX inherited ?
    ### Response:
    GSD IX can have different inheritance patterns depending on the genetic cause of the condition.  When caused by mutations in the PHKA1 or PHKA2 gene, GSD IX is inherited in an X-linked recessive pattern. These genes are located on the X chromosome, which is one of the two sex chromosomes.
