[The carbohydrate deficient glycoprotein syndrome]

Abstract

The carbohydrate-deficient glycoprotein syndrome is a newly described hereditary disorder which may be due to a defect in the glycoprotein metabolism. Predominant symptoms are mental retardation, epilepsy, cerebellar ataxia, polyneuropathy, squint, retinitis pigmentosa, retarded growth, hypothyroidism and liver steatosis. Increased serum glycoprotein-deficient transferrin is a marker of the disease and confirms the diagnosis. We describe four Norwegian children with this syndrome. Olivopontocerebellar degeneration was found upon examination of the brain in two patients who died.
