What is Beckwith Wiedemann syndrome?

Beckwith-Wiedemann syndrome (BWS) is a rare genetic growth disorder present at birth, causing infants to be unusually large (macrosomia) and leading to other symptoms like an enlarged tongue (macroglossia), low blood sugar (hypoglycemia), and abdominal wall defects (omphalocele/hernia). It results from faulty gene expression on chromosome 11, leading to overgrowth and an increased risk for certain childhood cancers, especially Wilms tumor and hepatoblastoma, though growth often slows by age 8.


What is the life expectancy of someone with Beckwith-Wiedemann syndrome?

Most individuals with Beckwith-Wiedemann Syndrome (BWS) have a normal life expectancy, as early detection and management of childhood risks like hypoglycemia and tumors (Wilms tumor, hepatoblastoma) have significantly improved outcomes, allowing most to grow into healthy adults with typical lifespans. While there's a small risk for life-threatening issues in infancy, effective monitoring leads to average life expectancy for the majority. 

What are the symptoms of Beckwith-Wiedemann syndrome?

Beckwith-Wiedemann Syndrome (BWS) symptoms vary but often include being large at birth (macrosomia), an enlarged tongue (macroglossia), low blood sugar (hypoglycemia) in newborns, abdominal wall defects like umbilical hernias, earlobe creases/pits, and overgrowth of one side of the body (hemihyperplasia), plus an increased risk of childhood tumors like Wilms tumors and hepatoblastomas, requiring regular cancer screenings. 


What is the most common cause of Beckwith-Wiedemann syndrome?

Causes. The genetic causes of Beckwith-Wiedemann syndrome are complex. The condition usually results from the abnormal regulation of genes in a particular region of chromosome 11. People normally inherit one copy of this chromosome from each parent.

Can you outgrow Beckwith-Wiedemann syndrome?

There's no cure for Beckwith-Wiedemann syndrome. But there are many treatments available to correct physical differences and relieve your child's symptoms. BWS usually doesn't cause any serious medical issues.


Introduction to Beckwith-Wiedemann Syndrome (BWS)



What are the facial features of Beckwith-Wiedemann?

Beckwith-Wiedemann Syndrome (BWS) facial features often include an enlarged tongue (macroglossia), distinctive ear creases or pits, and sometimes a red birthmark (nevus flammeus) on the forehead or eyelids, along with potential facial asymmetry from hemihypertrophy (overgrowth). Other signs can be a protruding lower jaw (mandibular prognathism) and an open bite due to the tongue pushing teeth apart, though severity varies greatly. 

What does a child with BWS look like?

BWS has various signs and symptoms, including a large body size at birth and taller-than-average height during childhood, a large tongue, and hypoglycemia (low blood sugar). In some children with BWS, parts of the body, such as the ears, may grow abnormally large, leading to an asymmetric or uneven appearance.

Is Beckwith-Wiedemann syndrome a disability?

Beckwith-Wiedemann Syndrome (BWS) isn't always classified as a disability, but its wide range of symptoms, like enlarged organs, breathing/feeding issues (due to a large tongue), and a higher cancer risk, often require significant medical management and can impact daily life, making some individuals eligible for disability support, especially if cognitive, social, or developmental challenges arise, though most with BWS grow into adulthood with normal intelligence and lifespan. 


What are the facial features of Wiedemann-Steiner?

Characteristic dysmorphic features.

Long eyelashes. Vertically narrow palpebral fissures. Widely spaced eyes. Wide nasal bridge with broad or bulbous tip.

What causes a baby to have a big tongue?

Children can have a large tongue due to several medical conditions: Acromegaly (gigantism) Amyloidosis. Beckwith-Wiedemann syndrome.

What is another name for Beckwith-Wiedemann syndrome?

Alternate Names

Beckwith Wiedemann Syndrome. Beckwith-Wiedemann syndrome. Exomphalos Macroglossia Gigantism Syndrome. Exomphalos-Macroglossia-Gigantism Syndrome.


What does a large tongue indicate?

Macroglossia, sometimes called giant tongue or enlarged tongue, is a rare condition that typically affects more children than adults. Most people have macroglossia because they have other conditions, such as Beckwith-Wiedemann syndrome or Down syndrome.

How to test for Beckwith-Wiedemann?

Beckwith-Wiedemann Syndrome (BWS) testing involves clinical evaluation of features (like large tongue, overgrowth) followed by genetic tests focusing on chromosome 11p15, primarily methylation analysis (MLPA) and copy number analysis, with CDKN1C gene sequencing and chromosomal studies (microarray, FISH) used if initial tests are negative. Samples like blood, buccal swabs, or affected tissue are used, with different tissues sometimes improving detection, as a negative result doesn't always rule out BWS.
 

What are the physical features of Beckwith-Wiedemann syndrome?

There is a wide range of physical features associated with Beckwith-Wiedemann syndrome/spectrum. These include: Large birth weight and length (macrosomia) Overgrowth of one side or one part of the body (lateralized overgrowth or hemihypertrophy/hemihyperplasia)


Does Williams syndrome affect height?

Williams syndrome may cause poor growth in childhood, and most adults with the condition are shorter than average. Williams syndrome can also cause endocrine concerns like having too much calcium in your blood and urine, an underactive thyroid and early puberty.

Does Beckwith-Wiedemann syndrome affect the brain?

Our data suggest that brain malformations may present as a finding within the BWS phenotype when the molecular etiology involves imprinted domain 2. Brain imaging may be useful in identifying such malformations in individuals with BWS and neurodevelopmental issues.

How do I know if my baby has Beckwith-Wiedemann syndrome?

Exams and Tests

The health care provider will do a physical exam to look for signs and symptoms of Beckwith-Wiedemann syndrome. Often this is enough to make a diagnosis. Tests for the disorder include: Blood tests for low blood sugar.


What's the highest IQ of a person with Down syndrome?

While the average IQ for individuals with Down syndrome is around 50, representing mild to moderate intellectual disability (ID), scores vary significantly, with some individuals reaching IQs in the 70+ range, particularly those with mosaic Down syndrome, where some cells are normal, allowing for higher cognitive function, though the highest documented IQs remain in the upper mild to borderline range for the syndrome, with some reports mentioning scores as high as 120 in rare cases. 

What are the top 3 genetic disorders?

What are common genetic disorders? Down syndrome (Trisomy 21). Fragile X syndrome. Klinefelter syndrome.

Is Beckwith-Wiedemann inherited?

Yes, Beckwith-Wiedemann Syndrome (BWS) can be hereditary, but most cases (around 85%) happen randomly due to new genetic changes, while about 10-15% are passed down in families, often via changes on chromosome 11, leading to growth gene imbalances. Familial cases might follow an autosomal dominant pattern, meaning one altered gene copy from a parent is enough, though sometimes parents with the altered gene show no symptoms.
 


Is Williams syndrome related to autism?

Background The hallmark of the neurobehavioural phenotype of Williams-Beuren syndrome (WBS) is increased sociability and relatively preserved language skills, often described as opposite to autism spectrum disorders (ASD). However, the prevalence of ASD in WBS is 6–10 times higher than in the general population.

What does Beckwith-Wiedemann syndrome look like?

Beckwith-Wiedemann syndrome (BWS) features include being large at birth, an enlarged tongue (macroglossia), abdominal wall defects (like omphalocele/umbilical hernia), low blood sugar (hypoglycemia), and asymmetrical body overgrowth (hemihyperplasia), often with earlobe creases/pits and a higher risk of certain childhood cancers like Wilms tumor.
