Which of the following are characteristics of Turner syndrome?

What are the characteristics of Turner 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.

Which of the following represents Turner syndrome?

Turner syndrome (TS), also known as 45,X, or 45,X0, is a genetic condition in which a female is partly or completely missing an X chromosome. Signs and symptoms vary among those affected.

What is the most common cause of Turner syndrome?

The cause of Turner syndrome is a completely or partially missing X chromosome. Turner syndrome symptoms include short stature and lack of breast development and periods. Treatment for Turner syndrome may include hormone therapy.

When do symptoms of Turner syndrome appear?

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 Turner syndrome Class 12?

Turner syndrome is a female-specific genetic condition caused by a partial or total deletion of one of the X chromosomes. Turner syndrome is also known as monosomy of the X chromosome.

How does Turner syndrome occur?

Turner syndrome occurs when part or all of an X chromosome is missing from most or all of the cells in a girl’s body. A girl normally receives one X chromosome from each parent. The error that leads to the missing chromosome appears to happen during the formation of the egg or sperm.

What is the karyotype of Turner syndrome?

Turner syndrome is sporadic. A majority of cases ascertained prenatally have a 45,X karyotype. Paternal nondisjunction accounts for ∼70% of liveborn cases with a 45,X.

Is Turner syndrome caused by aneuploidy?

Monosomy is another type of aneuploidy in which there is a missing chromosome. A common monosomy is Turner syndrome, in which a female has a missing or damaged X chromosome.

How is Turner syndrome diagnosed?

If, based on signs and symptoms, the doctor suspects that your child has Turner syndrome, a lab test will typically be done to analyze your child’s chromosomes. The test involves a blood sample. Occasionally, your doctor also may request a cheek scraping (buccal smear) or skin sample.

Is Turner syndrome caused by Nondisjunction?

Turner syndrome (TS) is a complex phenotype associated with complete or partial monosomy of the X chromosome, usually the result of a sporadic chromosomal nondisjunction. TS is one of the most common sex chromosome abnormalities, affecting approximately 1 in 2,000 live born females [1–3].
