What organs does Turner syndrome affect?

Turner syndrome, a condition that affects only females, results when one of the X chromosomes (sex chromosomes) is missing or partially missing. Turner syndrome can cause a variety of medical and developmental problems, including short height, failure of the ovaries to develop and heart defects.

Do Turner’s syndrome have ovaries?

Girls who have Turner syndrome don’t have typical ovarian development. Because the ovaries are responsible for making the hormones that control breast growth and menstruation, most girls with TS won’t go through all the changes associated with puberty unless they get treatment for the condition.

How does Turner syndrome affect the endocrine system?

Short stature and delayed growth. Abnormal puberty: Girls with Turner syndrome do not have ovaries but do have normal female external sex organs. However, because they lack ovaries (and thus the female sex hormone estrogen), girls with Turner do not develop breasts and do not have menstruation during puberty.

Does Turner syndrome affect the heart?

Heart disease is very common in Turner syndrome. Various studies using different imaging techniques have demonstrated that 25-50% of patients with TS have some form of congenital cardiovascular defect.

Does Turner syndrome affect the brain?

Turner syndrome (TS) results from the absence of an X chromosome in females. This genetic condition is associated with specific cognitive deficits and variations in brain volumes.

Why does Turner syndrome only affect females?

The condition only occurs in females. Most commonly, a female with Turner syndrome has only 1 X chromosome. Others may have 2 X chromosomes, but one of them is incomplete. Sometimes, a female has some cells with 2 X chromosomes, but other cells have only 1.

Do patients with Turner syndrome have a uterus?

In Turner’s syndrome, ovaries appear streaky but uterus, tubes, cervix and vaginal development will be normal.

What hormones does Turner syndrome affect?

Oestrogen and progesterone are the female hormones responsible for sexual development. Oestrogen also helps prevent brittle bones (osteoporosis). In girls with Turner syndrome, the ovaries (female reproductive organs) do not work properly.

Does Turner syndrome affect the pituitary gland?

Although Turner syndrome is not uncommon, studies of the pituitary in this condition are few. We undertook a histochemical and immunohistochemical study of four cases. As expected, “gonadal failure cells” were seen, but without recognizable gonadotroph hyperplasia. No gonadotroph adenomas were encountered.

What hormone is involved in Turner syndrome?

Age. As a chromosomal disorder, Turner syndrome is present at conception or following the first cell division and remains throughout life. Gonadotropin levels, particularly follicle-stimulating hormone (FSH) levels, may be elevated at birth, although not reliably enough for use in neonatal screening.

What is the most common cardiac anomaly in Turner syndrome?

These abnormalities are mostly left heart obstructions, the most common of which are bicuspid aortic valve (16%) and coarctation of the aorta (11%).

Why do people with Turner syndrome have heart defects?

This is the most common heart defect among people with Turner syndrome. Coarctation (narrowing) of the aorta: The artery carrying blood from the heart to the body is too narrow. This narrowing causes the heart to pump harder.

What is Holt Oram Syndrome?

Holt-Oram syndrome is characterized by skeletal abnormalities of the hands and arms (upper limbs) and heart problems. People with Holt-Oram syndrome have abnormally developed bones in their upper limbs. At least one abnormality in the bones of the wrist (carpal bones) is present in affected individuals.

Can you have a baby if you have Turner syndrome?

It is caused by a random error that leads to a missing X chromosome in the sperm or egg of a parent. Very few pregnancies in which the fetus has Turner Syndrome result in live births. Most end in early pregnancy loss. Most women with Turner syndrome cannot get pregnant naturally.

What is the main cause of Turner syndrome?

Turner syndrome is caused by partial or complete loss (monosomy) of the second sex chromosome. Chromosomes are found in the nucleus of all body cells. They carry the genetic characteristics of each individual and they come in pairs.

What is the lifespan of a person with Turner syndrome?

TS is associated with a 3-fold increase in overall mortality and a life expectancy that is reduced by up to 13 yr (8, 9). Even after exclusion of deaths from congenital heart disease, the mortality rates remain excessive, particularly in women with 45,X monosomy.
