    What are the genetic changes related to alpha thalassemia X-linked intellectual disability syndrome ?
    ### Response:
    Alpha thalassemia X-linked intellectual disability syndrome results from mutations in the ATRX gene. This gene provides instructions for making a protein that plays an essential role in normal development. Although the exact function of the ATRX protein is unknown, studies suggest that it helps regulate the activity (expression) of other genes.
