Description : Congenital disorders of glycosylation (CDG), previously called carbohydrate-deficient
glycoprotein syndromes (CDGSs), are a group of 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 (IEF) 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) and CDG1B (602579).;
Inheritance : Autosomal recessive;
Molecular basis : Caused by mutation in the alpha-1,6-mannosyltransferase gene (ALG12, 607144.0001);
Laboratory abnormalities : Abnormal glycosylation of transferrin, type 1 pattern;
