What is Turner syndrome in a baby?

Overview. 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.

Can a baby survive with Turner syndrome?

(Because a Y chromosome is needed for a person to be male, all babies with Turner syndrome are girls.) Though girls born with Turner syndrome usually have good odds for a normal life, the majority of babies with the condition are lost to miscarriage or stillbirth.

How does a baby get Turner syndrome?

Turner syndrome is usually not inherited, but it is genetic. 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.

What is the life expectancy of someone with Turner’s syndrome?

The long-term outlook ( prognosis ) for people with Turner syndrome is typically good. Life expectancy is slightly shorter than average but may be improved by addressing and treating associated chronic illnesses, such as obesity and hypertension .

Is Turner’s syndrome fatal?

There’s no cure for Turner syndrome but many of the associated symptoms can be treated. Girls and women with Turner syndrome will need to have their heart, kidneys and reproductive system checked regularly throughout their lives. However, it’s usually possible to lead a relatively normal and healthy life.

Does Turner syndrome come from Mom or Dad?

Turner syndrome is not caused by anything the parents did or did not do. The disorder is a random error in cell division that happens when a parent’s reproductive cells are being formed. Girls born with the X condition in only some of their cells have mosaic Turner syndrome.

Can Turner syndrome go undiagnosed?

In some cases, the disorder is diagnosed before birth or shortly after birth. However, mild cases can remain undiagnosed until later in life and even during adulthood.

Can Turner syndrome be cured?

Because TS is a chromosomal disorder, there’s no cure for the condition. But a number of treatments can help: Growth hormone, either alone or with other hormone treatment, may improve growth and will usually increase final adult height — often into the normal range if treatment is started early enough.

Can Turner syndrome detected before birth?

Turner syndrome is usually identified during childhood or at puberty. However, it can sometimes be diagnosed before a baby is born using a test called amniocentesis.

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 people with Turner syndrome survive?

The survival rate of people with Turner syndrome is typically good. Life expectancy is slightly shorter than average but can be improved by treating underlying chronic illnesses, such as obesity and hypertension. Heart disease is an important cause of death in these individuals.

Does Turner syndrome run in families?

Turner syndrome is a genetic disorder, but it’s usually not inherited, except in rare cases. An inherited genetic condition means that a parent (or both parents) passed down a mutated, or changed, gene. In Turner syndrome, the chromosome change happens randomly before birth.

What are the specific symptoms of Turner syndrome?

Signs of Turner syndrome at birth or during infancy may include:

  • Wide or weblike neck.
  • Low-set ears.
  • Broad chest with widely spaced nipples.
  • High, narrow roof of the mouth (palate)
  • Arms that turn outward at the elbows.
  • Fingernails and toenails that are narrow and turned upward.
