Most people have two sex chromosomes—one from each parent. Males have an X and a Y chromosome, while females have two X chromosomes. Turner syndrome occurs when a female has only one complete X chromosome. Girls with Turner syndrome tend to be shorter, and their ovaries do not produce the normal amount of female hormones.
Turner syndrome also can cause problems with many other parts of your daughter's body. Her aorta—the major blood vessel that takes blood from the heart to the body—may become narrow. This can raise blood pressure. Turner syndrome also can cause kidney problems, osteoporosis, diabetes, and a lack of thyroid hormone.
Turner syndrome is not usually passed down in families. It happens by chance. Sometimes a test done while a women is pregnant (an amniocentesis) shows that a baby will be born with Turner syndrome.
Estrogen and growth hormone can help girls with Turner syndrome to develop at the time of puberty. Estrogen can help girls develop breasts. Growth hormone helps them grow in height. But women with this condition usually can't become pregnant without medical help. They may be able to have a baby with an egg from another woman.
Follow-up care is a key part of your child's treatment and safety. Be sure to make and go to all appointments, and call your doctor or nurse call line if your child is having problems. It's also a good idea to know your child's test results and keep a list of the medicines your child takes.
Watch closely for changes in your child's health, and be sure to contact your doctor or nurse call line if your child has any problems.
