Understanding Turner Syndrome Symptoms In Infants

Introduction

Turner syndrome is a genetic condition that affects females, typically resulting from the absence of one complete or partial X chromosome. This syndrome, occurring in approximately 1 in 2,500 live female births, presents a range of symptoms that can significantly impact an individual's health and development.¹ While the diagnosis of Turner syndrome is often made during childhood or adolescence, it is crucial to recognise potential symptoms early on, even in infancy, to facilitate timely interventions and support.

In infants, Turner syndrome may manifest through various physical characteristics and health concerns. These can include slower growth rates, distinctive features such as a webbed neck and low-set ears, and potential health issues involving the heart, kidneys, and hearing. Understanding and identifying these symptoms early is vital for initiating appropriate medical evaluations and interventions to optimise the infant's health and well-being.

Diagnosing Turner syndrome in infants typically involves a combination of prenatal screening tests and postnatal diagnostic procedures. Prenatal screening may detect certain markers associated with Turner syndrome during pregnancy, prompting further evaluation after birth. Postnatal diagnostic tests such as karyotyping, hormonal assessments, and imaging studies are then conducted to confirm the diagnosis and assess any associated health complications.

While there is currently no cure for Turner syndrome, early detection allows implementation of various management strategies to address specific symptoms and improve the overall quality of life. These may include growth hormone therapy to support growth and development, estrogen replacement therapy to address hormonal imbalances, as well as regular monitoring and treatment of associated health issues.

This article  will focus on the common symptoms of Turner syndrome in infants. By providing accurate and accessible information, we aim to increase awareness and understanding of Turner syndrome symptoms among caregivers, healthcare professionals, and the wider community, ultimately promoting early detection and improved outcomes for the affected infants.

Symptoms of Turner syndrome in infants

Physical symptoms

• Growth delay:

 One of the hallmark signs of Turner syndrome in infants is a noticeable delay in growth compared to their peers. Babies with Turner syndrome may grow slower  leading to shorter stature and less weight gain.² Caregivers may observe that the infant is smaller in size or falls below the expected growth percentiles on growth charts.

• Webbed neck:

Another distinctive physical characteristic Turner syndrome infants have is a webbed neck.³ This refers to excess skin folds on the sides of the neck, giving it a broad or web-like appearance. The webbed neck can be subtle or more pronounced and is often identified during routine physical examinations.

• Low-set ears:

Infants with Turner syndrome may have ears that are positioned lower on the head compared to typical placement.⁴ This feature can contribute to the overall characteristic appearance associated with the syndrome. While low-set ears alone may not indicate Turner syndrome, when combined with other symptoms, they can raise suspicion for further evaluation.

• Swelling of hands and feet:

Swelling, particularly of the hands and feet, is another potential symptom of Turner syndrome in infants.⁵ This swelling, known as peripheral oedema, may result from fluid retention and can contribute to puffiness in these areas. Caregivers should monitor for any unusual swelling and report it to healthcare providers for evaluation.

Health issues

• Heart abnormalities:

Turner syndrome is associated with an increased risk of congenital heart defects, which are present at birth. These abnormalities can affect the structure and function of the heart, potentially leading to issues such as heart murmurs, valve problems, or structural abnormalities.⁶ Early detection through cardiac evaluations is essential for appropriate management.

• Kidney problems:

   Infants with Turner syndrome may also experience kidney abnormalities, including structural defects or dysfunction. These issues can affect the kidneys' ability to filter waste products from the blood and regulate fluid balance.⁷ Regular monitoring of kidney function and imaging studies may be necessary to assess for any renal complications.

• Hearing loss:

Hearing loss is a common concern in individuals with Turner syndrome, including infants.⁸ This can result from structural abnormalities in the ear or dysfunction of the auditory system. Infants with Turner syndrome should undergo regular hearing assessments to detect any hearing impairments early and implement appropriate interventions.

• Hormonal imbalances:

Hormonal imbalances are a key feature of Turner syndrome, affecting various aspects of growth, development, and reproductive function. Infants with Turner syndrome may experience deficiencies in certain hormones, such as growth hormone or thyroid hormone, which can impact their overall health and development. Hormonal testing and management are essential components of comprehensive care for individuals with Turner syndrome.⁹

Diagnosis of Turner syndrome in infants

Diagnosing Turner Syndrome in infants typically involves a combination of prenatal screening, postnatal clinical evaluation, and genetic testing. During routine check-ups, healthcare professionals may observe physical features associated with the condition and recommend further diagnostic tests, such as chromosomal analysis, to confirm the diagnosis.

Treatment and management

While there is no cure for Turner Syndrome, early intervention and ongoing management can help address symptoms and improve overall health and quality of life. Treatment options may include:

• Hormone therapy: Growth hormone therapy can help improve growth rates and final adult height.
• Surgical interventions: Surgical procedures may be necessary to address specific complications, such as heart or kidney abnormalities.
• Multidisciplinary approach: A team of healthcare professionals, including endocrinologists, cardiologists, and geneticists, collaborate to provide comprehensive care tailored to the individual's needs.

Prognosis and outlook

The prognosis for individuals with Turner Syndrome varies depending on the severity of symptoms and the effectiveness of treatment interventions. With appropriate medical care and support, many individuals with Turner Syndrome lead fulfilling lives. However, it is essential to monitor for potential health complications throughout childhood and adulthood.

FAQs

How do you know if you have Turner syndrome in pregnancy?

Turner syndrome can be detected during pregnancy through prenatal screening tests, such as amniocentesis or chorionic villus sampling (CVS), which examine the baby's chromosomes. Certain markers may prompt further testing, leading to a diagnosis.

What happens to the body if you have Turner syndrome?

Turner syndrome affects various aspects of physical development and health. Common manifestations include short stature, webbed neck, heart abnormalities, kidney problems, hearing loss, and hormonal imbalances affecting puberty and fertility.

What are the 2 main symptoms of Turner syndrome?

Two main symptoms of Turner syndrome include short stature (growth delay) and a webbed neck. However, it's important to note that individuals with Turner syndrome may experience a wide range of symptoms and health issues.

At what age is Turner syndrome diagnosed?

Turner syndrome is typically diagnosed during childhood or adolescence, usually between the ages of infancy and early puberty. However, it can sometimes be diagnosed prenatally through screening tests during pregnancy.

How early can Turner syndrome be detected in ultrasound?   

Turner syndrome can sometimes be detected during routine prenatal ultrasounds as early as the first trimester. However, additional diagnostic testing, such as amniocentesis or chorionic villus sampling, may be required for confirmation.

What does a female with Turner syndrome look like?
