Which characteristic is commonly associated with Turner syndrome?

Turner syndrome is a chromosomal condition that affects development in females. The most common feature of Turner syndrome is short stature, which becomes evident by about age 5. An early loss of ovarian function (ovarian hypofunction or premature ovarian failure) is also very common.

What is an interesting fact about Turner syndrome?

People with Turner syndrome have an abnormally short stature—the average height of a person with TS is 4 ft 8 in. Other distinctive physical features of TS include low-set ears, webbed neck (excess skin on the neck), scoliosis, and fingernails and toenails that turn upward.

When do symptoms of Turner syndrome appear?

Turner Syndrome occurs when one of the X chromosomes is missing, either partially or completely. Turner syndrome often causes short stature, typically noticeable by age 5. It usually doesn’t affect intelligence but can lead to developmental delays especially with calculations and memory. Heart problems are common, too.

What happens to the body when you have Turner’s syndrome?

Most women with Turner syndrome are infertile. A variety of additional symptoms can occur including abnormalities of the eyes and ears, skeletal malformations, heart anomalies, and kidney abnormalities. Intelligence is usually normal, but affected individuals may experience certain learning disabilities.

Do girls with Turner syndrome have periods?

Most girls with Turner syndrome do not produce enough of these sex hormones, which means: they may not begin sexual development or fully develop breasts without female hormone replacement therapy (HRT) they may begin sexual development but not complete it. they may not start their monthly periods naturally.

How do you detect Turner syndrome?

Karyotyping is a test that involves analysing the 23 pairs of chromosomes. It’s often used when Turner syndrome is suspected. The test can either be carried out while the baby is inside the womb – by taking a sample of amniotic fluid (amniocentesis) – or after birth by taking a sample of the baby’s blood.

Can you have mild Turner’s syndrome?

While 95% of girls with Turner syndrome have short stature, many have few or no other phenotypic features, often resulting in late or missed diagnosis. Mosaicism can occur, leading to a milder presentation and often making recognition of the condition more difficult.

What are Turner syndrome characteristics quizlet?

Turner syndrome usually does not affect intelligence. Common physical symptoms of Turner Syndrome include a stocky build, arms that turn out slightly at the elbow, a receding lower jaw, a short webbed neck, and a low hairline at the back of the neck.

What learning disabilities are associated with Turner syndrome?

For example, Turner syndrome is a proposed etiology of the nonverbal learning disability – because of reported relative strengths in verbal skills, and relatively weaker nonverbal skills – particularly in arithmetic, select visuospatial skills, and processing speed.

How many chromosomes does a person with Turner syndrome have quizlet?

The resulting zygote has the genotype XXY. Turner syndrome results when a gamete without any sex chromosome fuses with a normal gamete with one X chromosome. A person with Turner’s syndrome has 45 chromosomes, while a person with Klinefelter’s syndrome has 47 chromosomes.

How many chromosomes are present in Turner’s syndrome?

To diagnose Turner syndrome, doctors use a special blood test that looks at chromosomes, called a karyotype test (chromosomal analysis). Results that indicate TS show only one X chromosome instead of two X chromosomes, with a total of 45 chromosomes instead of the usual 46.

Does Turner syndrome affect personality?

A personality style characterized by traits related to low neuroticism and high extroversion has been reported for females with Turner syndrome, indicating possible genetic factors related to personality development.

Does Turner’s syndrome causes mental retardation?

Unlike some other genetic conditions, Turner Syndrome does not cause mental retardation or decreased intelligence. However some girls with Turner Syndrome have learning disabilities, especially in areas involving spatial skills, such as math.

Is Turner syndrome special needs?

Those students whose Turner syndrome adversely affects their educational performance may benefit from special education under the Individuals with Disabilities Education Act (IDEA). To qualify under IDEA, a student must meet eligibility criteria in one of thirteen specific disability categories.
