    ### Instruction:
    What are the genetic changes related to eosinophil peroxidase deficiency ?
    ### Response:
    Mutations in the EPX gene cause eosinophil peroxidase deficiency. The EPX gene provides instructions for making the eosinophil peroxidase protein. During an immune response, activated eosinophils release eosinophil peroxidase at the site of injury. This protein helps form molecules that are highly toxic to bacteria and parasites.
