Nancy has Turner syndrome, which is caused by missing or partially missing X chromosome. This can result in various physical and developmental abnormalities, such as webbed neck, short stature, and difficulties with math. Hormone therapy may be used to treat some of these symptoms, but it can also cause reproductive sterility. Fragile X syndrome, Klinefelter syndrome, and Down syndrome all involve different genetic abnormalities and are not consistent with the symptoms described for Nancy.
