Turner syndrome is caused by the complete or partial absence of the X chromosome in females. This results in a variety of characteristics, including a webbed neck, short stature, and difficulty with math. Hormone therapy is often used as a treatment option for Turner syndrome, but it can also result in reproductive sterility. Fragile X syndrome is a genetic condition that affects both males and females, causing intellectual disability and behavioral challenges. Klinefelter syndrome is a genetic condition that affects males, resulting in the presence of an extra X chromosome and causing infertility and other physical characteristics. Down syndrome is a genetic condition caused by an extra copy of chromosome 21, resulting in developmental delays and other physical characteristics.
