Beckwith-Wiedemann syndrome
Beckwith-Wiedemann syndrome is a growth disorder that causes large body size, large organs, and other symptoms. It is a congenital condition, which means it is present at birth. The signs and symptoms of the disorder vary somewhat from child to child.
Infancy can be a critical period in babies with this condition because of the possibility of:
- Low blood sugar
- A type of hernia called an omphalocele (when present)
- An enlarged tongue (macroglossia)
-
An increased rate of
tumor
growth.
Wilms tumors
and hepatoblastomas are the most common tumors in children with this syndrome.
Tumor
A tumor is an abnormal growth of body tissue. Tumors can be cancerous (malignant) or noncancerous (benign).
Wilms tumors
Wilms tumor (WT) is a type of kidney cancer that occurs in children.
Causes
Beckwith-Wiedemann syndrome is caused by a defect in the genes on chromosome 11. About 10% of cases can be passed down through families.
Chromosome
Chromosomes are structures found in the center (nucleus) of cells that carry long pieces of DNA. DNA is the material that holds genes. It is the bu...
Symptoms
Signs and symptoms of Beckwith-Wiedemann syndrome include:
- Large size for a newborn
- Red birth mark on forehead or eyelids ( Nevus flammeus )
- Creases in ear lobes
- Large tongue (macroglossia)
- Low blood sugar
-
Abdominal wall defect (
umbilical hernia
or
omphalocele
)
Umbilical hernia
An umbilical hernia is an outward bulging (protrusion) of the lining of the abdomen or part of the abdominal organ(s) through the area around the bel...
Omphalocele
An omphalocele is a birth defect in which an infant's intestine or other abdominal organs are outside of the body because of a hole in the belly butt...
- Enlargement of some organs
- Overgrowth of one side of the body (hemihyperplasia/hemihypertrophy)
- Tumor growth, such as Wilms tumors and hepatoblastomas
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
- Chromosomal studies for abnormalities in chromosome 11
-
Ultrasound of the abdomen
Ultrasound of the abdomen
Abdominal ultrasound is a type of imaging test. It is used to look at organs in the abdomen, including the liver, gallbladder, spleen, pancreas, and...
Treatment
Infants with low blood sugar may be treated with fluids given through a vein ( intravenous , IV). Some infants may need medicine or other management if low blood sugar continues.
Intravenous
Intravenous means "within a vein. " Most often it refers to giving medicines or fluids through a needle or tube inserted into a vein. This allows th...
Defects in the abdominal wall may need to be repaired. If the enlarged tongue makes it hard to breath or eat, surgery may be needed, Children with overgrowth on one side of the body should be watched for a curved spine ( scoliosis ). The child also must be watched closely for the development of tumors. Tumor screening includes blood tests and abdominal ultrasounds.
Scoliosis
Scoliosis is an abnormal curving of the spine. Your spine is your backbone. It runs straight down your back. Everyone's spine naturally curves a b...
Outlook (Prognosis)
Children with Beckwith-Wiedemann syndrome typically lead normal lives. Further study is needed to develop long-term follow-up information.
Possible Complications
These complications can occur:
- Development of tumors
- Feeding problems due to enlarged tongue
- Breathing problems due to enlarged tongue
- Scoliosis due to hemihypertrophy
When to Contact a Medical Professional
If you have a child with Beckwith-Wiedemann syndrome and worrisome symptoms develop, call your pediatrician right away.
Prevention
There is no known prevention for Beckwith-Wiedemann syndrome. Genetic counseling may be of value for families who would like to have more children.

Beckwith-Wiedemann syndrome is an inherited growth disorder. Babies with this syndrome may have a range of symptoms. These symptoms may include large tongue (macroglossia), large organs (visceromegaly), large body size (macrosomia), abdominal wall defects (umbilical hernia or omphalocele), and overgrowth on one side of the body (hemihyperplasia/hemihypertrophy).
