Question 1

Who is affected by Turner Syndrome?

Accepted Answer

Turner Syndrome is a genetic disorder characterized by the partial or complete absence of one X chromosome, affecting only those who are biologically female.

It occurs in about 1 in 2,000 to 2,500 live female births and is consistent across different ethnicities and regions, indicating no specific racial or environmental factors.

The condition is present from conception, but diagnosis can vary; some may be identified prenatally or shortly after birth, while others may not be diagnosed until later in childhood or adolescence when growth issues become noticeable.

Question 2

What types or variants of Turner Syndrome exist?

Accepted Answer

Conditions related to Turner syndrome include:

Complete absence of one X chromosome (45,X monosomy)

Mosaicism involving 45,X and other cell lines

Structural abnormalities such as isochromosome Xq and others

Question 3

What are the signs and symptoms of Turner Syndrome?

Accepted Answer

Common signs and symptoms include:

Short stature: Typically noticeable by age five.

Ovarian dysgenesis: Can result in delayed or absent puberty and infertility.

Webbed neck: Known as pterygium colli, along with a low hairline at the back of the neck.

Lymphedema: Swelling of the hands and feet, which may be present at birth.

Broad, shield-shaped chest: Often accompanied by widely spaced nipples.

Question 4

What are the causes and risk factors of Turner Syndrome?

Accepted Answer

Monosomy X, or the complete loss of one X chromosome, is estimated to occur in up to 50% of cases. Other factors include:

Mosaicism, where some cells have a missing or altered X chromosome due to early fetal development errors.

Structural abnormalities of the X chromosome, such as isochromosomes or ring chromosomes.

Additional factors may also be involved.

Question 5

What is the course or nature of Turner Syndrome?

Accepted Answer

Turner Syndrome is a lifelong condition that typically shows clinical features in infancy or early childhood, with significant variability in severity and manifestations based on individual chromosomal configurations.

Developmental Progression

Physical characteristics may be evident at birth, but some individuals might not be diagnosed until school age or puberty. Growth patterns often diverge from typical standards during childhood, and many experience insufficient pubertal development due to ovarian insufficiency.

Long-Term Clinical Outlook

Adults with Turner Syndrome require ongoing monitoring for potential systemic complications, including cardiovascular, endocrine, and auditory issues, which may develop or worsen over time. A multidisciplinary approach is essential for managing health and clinical needs.

Question 6

How is Turner Syndrome diagnosed?

Accepted Answer

A definitive diagnosis of Turner syndrome is confirmed through genetic testing that identifies chromosomal abnormalities. While physical features may prompt initial evaluation, the condition can be diagnosed at various life stages, from prenatal to adulthood.

Clinical Assessment

Clinicians assess for characteristic signs during physical examinations. In newborns, signs may include:

Lymphedema (swelling) of hands and feet

Webbed neck

In older children and adolescents, key indicators often include:

Short stature

Delayed onset of puberty

Prenatal diagnosis may occur if fetal ultrasound shows markers like increased nuchal translucency or cystic hygroma. Non-invasive prenatal screening (NIPT) can suggest sex chromosome abnormalities but is not definitive.

Genetic Confirmation

A blood test called a karyotype is used to confirm the diagnosis by analyzing the number and structure of chromosomes. This test can reveal:

Complete or partial absence of an X chromosome (monosomy X)

Mosaicism, where some cells have typical sex chromosomes while others show Turner syndrome patterns

Once confirmed, further evaluations like echocardiography or renal ultrasound are often conducted to check for related heart or kidney issues.

Question 7

How is Turner Syndrome treated?
