Congenital disorder of glycosylation type 1A

A genetically heterogeneous group of autosomal recessive disorders caused by enzymatic defects in the synthesis and processing of ASPARAGINE (N)-linked glycans or OLIGOSACCHARIDES on GLYCOPROTEINS. Affected individuals exhibit a range of growth, neuromuscular, eye, liver, immunologic, and gastrointestinal abnormalities; 20% die in the first year of life due to infections, HEPATIC INSUFFICIENCY or CARDIOMYOPATHY. Mutations have been identified in the PMM2 gene for type Ia. OMIM: 212065

Also Known As:

Carbohydrate-Deficient Glycoprotein Syndrome Type Ia; Carbohydrate-deficient glycoprotein syndrome type 1A; Congenital Disorder of Glycosylation Type Ia; Congenital Disorder of Glycosylation, Type Ia; Jaeken syndrome; PMM2 deficiency; Phosphomannomutase 2 deficiency; Pmm2-CDG
