Beckwith-Wiedemann syndrome
Definition
Beckwith-Wiedemann syndrome is a congenital (present from birth) growth disorder that causes large body size, large organs, and other problems.
Causes
The cause of Beckwith-Wiedemann syndrome is unknown, but it may be genetic. Eighty percent of cases are associated with a defect in chromosome number 11.
Infancy can be a critical period because of low blood sugar (hypoglycemia), omphalocele (when present), and an increased rate of tumor development, with Wilm's tumor and adrenal carcinoma being most common.
Symptoms
Exams and Tests
The signs of Beckwith-Wiedemann syndrome include:
Tests for Beckwith-Wiedemann syndrome include:
Treatment
In infancy, hypoglycemia may be treated with intravenous solutions. Enlargement of the tongue can cause problems with feeding and sleeping.
Defects in the abdominal wall may need to be repaired. The children must be watched closely for the development of tumors.
Outlook (Prognosis)
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.
Possible Complications
- Development of tumors
- Feeding problems
- Hypoglycemia
- Respiratory difficulties from obstruction due to large tongue
- Seizures
When to Contact a Medical Professional
If you have a child with Beckwith-Wiedemann syndrome and worrisome symptoms develop, call your pediatrician immediately.
Prevention
There is no known prevention for Beckwith-Wiedemann syndrome. Genetic counseling may be of value for families who would like to have additional children.
