The carbohydrate-deficient glycoprotein (CDG) syndromes are a group of genetic multisystem disorders with invariable involvement of the nervous system including severe olivopontocerebellar atrophy. We report two sets of sibs in whom the diagnosis of CDG syndrome type 1 was recognized at an older age
An 8-month-old male infant who presented in the neonatal period with failure to thrive, bilateral pleural and pericardial effusions, and hepatic insufficiency characterized by elevated liver functions tests and hypoalbuminemia was found at autopsy to have an unusual combination of
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,
Carbohydrate-deficient glycoconjugate (CDG) syndrome type I due to phosphomannomutase deficiency (CDGIA) is the most common among a group of metabolic disorders characterized by a defective glycosylation of glycoconjugates. Clinically it is a multisystem disease with an important involvement of the
Carbohydrate-deficient glycoprotein syndrome type 1 (CDG1) (MIM: 212065) is an autosomal recessive disorder with psychomotor retardation, strokelike episodes, ataxia, and olivopontocerebellar atrophy (OPCA) of neonatal onset. Recently, DNA substitutions in a gene for phosphomannomutase 2 (PMM2),
Infantile olivopontocerebellar atrophies are rare progressive, fatal, neurologic conditions characterized pathologically by loss of neurons and gliosis in the cerebellum, pons, and inferior olivary nuclei in early life. The clinical and pathologic features of 2 brothers who presented in early
The carbohydrate-deficient glycoprotein syndrome is a newly recognised genetic disorder characterised by mental retardation, liver disfunction during infancy, cerebellar ataxia and atrophy, polyneuropathy, growth retardation, stroke-like episodes, and the appearance of carbohydrate-deficient
A boy with carbohydrate-deficient glycoprotein syndrome died at five months of age in status epilepticus. Postmortem examination failed to show the classically observed olivopontocerebellar atrophy. Two previously unreported features were present: cataracts from the first week of life and lysosomal
The carbohydrate-deficient glycoprotein (CDG) syndrome in its most severe form (neonatal olivopontocerebellar atrophy) is a life-threatening multisystem disease. We report a neonate who was referred for cardiological assessment because of respiratory distress, a murmur and episodes of desaturation.
