The Jaeken syndrome is the congenital disorder of glycosylation type IA (CDG-IA). This is the most common type of CDG syndrome .
Synonyms are:
- Carbohydrate-Deficient Glycoprotein Syndrome Ia
- Congenital defect of glycoprotein biosynthesis type Ia
- Phosphomannomutase-2 deficiency
- CDG syndrome type Ia, CDG-1a
The name refers to the first description in 1980 by the Belgian pediatrician J. Jaeken .
distribution
The frequency is not known, the inheritance is done autosomal - recessive .
root cause
The disease is based on mutations in the PMM2 gene at location 16p13.2.
Clinical manifestations
The disease can appear in very different ways. In infants, failure to thrive with vomiting and diarrhea can be the first signs. Later, encephalopathy with decreased muscle tone, psychomotor retardation , abnormal eye movements, and signs of peripheral neuropathy can occur.
