What is Turner syndrome and how does it occur?

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.

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.

Why do only females get Turner syndrome?

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.

How is Turner syndrome transmitted?

Most cases of Turner syndrome are not inherited. When this condition results from monosomy X , the chromosomal abnormality occurs as a random event during the formation of reproductive cells (eggs and sperm) in the affected person’s parent.

Who is most likely to get Turner syndrome?

Turner syndrome is a genetic condition found in females only. It affects about 1 in every 2,500 girls. Girls who have this condition usually are shorter than average and infertile due to early loss of ovarian function.

What are three symptoms of Turner’s syndrome?

Features of Turner syndrome may include a short neck with a webbed appearance, low hairline at the back of the neck, low-set ears, hands and feet that are swollen or puffy at birth, and soft nails that turn upward. Stature. Girls with Turner syndrome grow more slowly than other children.

Is Turner syndrome inherited from mother or father?

Is Turner syndrome inherited? 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.

Can Turner syndrome have babies?

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. In one study, as many as 40% of women with Turner syndrome got pregnant using donated eggs.

Do Turner syndrome have periods?

About 2-5% of individuals with Turner syndrome have spontaneous periods and have the potential to achieve pregnancy without medical intervention. However, many affected women have absent or decreased ovarian function and need hormone therapy to achieve their period.

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.

Why can’t males have Turner syndrome?

Turner syndrome is caused by a female having one normal X chromosome in each of her cells , while the other sex chromosome is either missing or structurally abnormal. Females without Turner syndrome have 2 full X chromosome in all of their cells, and males have one X chromosome and one Y chromosome .

Can Turner syndrome affect males?

Most females have a pair of sex chromosomes designated as XX, and most males have a pair of sex chromosomes designated as XY. In Turner syndrome, which only affects females, there is a partially or completely missing X chromosome.

Can you abort a baby with Turner syndrome?

What is the lifespan of a person with Turner syndrome?

What is the long-term outlook for people with Turner 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 .
