    What are the genetic changes related to immune dysregulation, polyendocrinopathy, enteropathy, X-linked syndrome ?
    ### Response:
    Mutations in the FOXP3 gene cause some cases of IPEX syndrome. The protein produced from this gene is a transcription factor, which means that it attaches (binds) to specific regions of DNA and helps control the activity of particular genes. This protein is essential for the production and normal function of certain immune cells called regulatory T cells.
