  • Reasons for wanting to have the genetic test for fragile X syndrome may include:
    • Knowing whether you are a carrier of fragile X syndrome.
    • Knowing whether you are at increased risk of having a child with fragile X syndrome.
    • Having information for family planning.
    • Knowing whether you are at increased risk of infertility or early menopause.
  • It is your choice whether to have the genetic carrier test for fragile X syndrome.
