A woman brings her six-year old daughter into clinic because she has just learned that her nephew has fragile X syndrome.
The daughter is in kindergarten and is doing well with no learning or behavioral concerns. The mother requests genetic testing for her daughter to "make sure she doesn't have fragile X."
What information does the nurse need to address this mother's request? Is the standard test for fragile X a chromosome, biochemical, or molecular test?
Do you consider this to be a carrier, diagnostic, or predisposition genetic test?
