Cerebellar hypoplasia in children with the carbohydrate-deficient glycoprotein syndrome.

We describe seven children with the carbohydrate-deficient glycoprotein syndrome, an autosomal recessive inborn error of protein glycosylation characterised by failure to thrive, neurological dysfunction and a unique pattern of physical abnormalities. Neuro-radiological investigations revealed cerebellar hypoplasia in all seven children. Two children also developed supratentorial atrophy following episodes of neurological deterioration.
