Preferred Label : Congenital disorder of glycosylation, type ih;
Symbol : CDG1H;
CISMeF acronym : CDG1H;
Type : Phenotype, molecular basis known;
Alternative titles and symbols : CDGIh; Cdg ih;
Description : CDGs, previously called carbohydrate-deficient glycoprotein syndromes, grew from hereditary
multisystem disorders first recognized by Jaeken et al. (1980). The characteristic
biochemical abnormality of CDGs is the hypoglycosylation of glycoproteins, which is
routinely determined by isoelectric focusing of serum transferrin. Type I CDG comprises
those disorders in which there is a defect in the assembly of lipid-linked oligosaccharides
or their transfer onto nascent glycoproteins, whereas type II CDG comprises defects
of trimming, elongation, and processing of protein-bound glycans. For a general discussion
of CDGs, see CDG1A (212065).;
Inheritance : Autosomal recessive;
Molecular basis : Caused by mutation in the homolog of the S. cerevisiae ALG8 gene (ALG8, 608103.0001);
Laboratory abnormalities : Hypoalbuminemia; Electrolyte disturbances; Abnormal isoelectric focusing of serum transferrin, consistent with CDG type I; Hypoglycosylation of serum glycoproteins;
Prefixed ID : #608104;
Origin ID : 608104;
