Beckwith-Wiedemann syndrome is a congenital (present from birth) growth disorder that causes large body size, large organs, and other symptoms.

• Abdominal wall defect: umbilical hernia or omphalocele
• Creases in ear lobes
• Enlargement of organs and tissues
• External ear (pinna) abnormalities and low-set ears
• Large size for a newborn (large for gestational age)
• Large, prominent eyes
• Large tongue, sometimes protruding
• Lethargy
• Low blood sugar (hypoglycemia)
• Mild microcephaly
• Poor feeding
• Separated abdominal muscles (diastasis recti)
• Seizures
• Undescended testicles (cryptorchidism)

• The cause of Beckwith-Wiedemann syndrome is unknown, but it may be genetic.
• Most cases are associated with a defect in chromosome 11.

• Blood tests for low blood sugar and other abnormalities
• Chromosomal studies for abnormalities in chromosome 11
• MRI or CT scan of the abdomen
• Ultrasound of the abdomen
• X-ray of the abdomen
• X-ray of the long bones

If you have a child with Beckwith-Wiedemann syndrome and worrisome symptoms develop, call your pediatrician immediately.

• Infants with low blood sugar may be treated fluids given through a vein ( intravenous solutions).
• Defects in the abdominal wall may need to be repaired. The child must be watched closely for the development of tumors.

Directions to Hospitals Treating Beckwith-Wiedemann syndrome

• There is no known prevention for Beckwith-Wiedemann syndrome.
• Genetic counseling may be of value for families who would like to have additional children.

• Children with Beckwith-Wiedemann syndrome who survive infancy do well, although no long-term follow-up information is available.
• Mental development appears to be normal to very slightly decreased. Swelling of the tongue can cause problems with feeding and sleeping.

• Development of tumors
• Feeding problems
• Hypoglycemia
• Respiratory difficulties from obstruction due to large tongue
• Seizures
