Beckwith-Wiedemann syndrome
Background
Beckwith-Wiedemann: Exomphalos-Macroglossia- Gigantism; Neo-natal Hypoglycaemia; Visceromegaly; Hemihypertrophy
Features of Beckwith-Wiedemann syndrome include:
- Macroglossia (a large tongue which may cause breathing, feeding or speech difficulties;
- Exomphalos (umbilical hernia);
- Over-growth (a high birth weight, and/or children who are bigger than their contemporaries);
- Hemihypertrophy (one side of the body grows more than the other);
- Hypoglycaemia (low blood sugar) after birth;
- Characteristic facial appearance;
- Creases or pits (indentations) of the ears.
There is an increased risk of tumour development, particularly Wilm's (kidney) tumours in some children with Beckwith-Wiedemann syndrome and children should be seen regularly to screen for these.
