Congenital disorder of glycosylation, type ifOMIM Phenotype
Preferred Label : Congenital disorder of glycosylation, type if;
Symbol : CDG1F;
CISMeF acronym : CDG1F;
Type : Phenotype, molecular basis known;
Alternative titles and symbols : CDGIf; Cdg if;
Description : Congenital disorders of glycosylation (CDGs) are metabolic deficiencies in glycoprotein
biosynthesis that usually cause severe mental and psychomotor retardation. Different
forms of CDGs can be recognized by altered isoelectric focusing (IEF) patterns of
serum transferrin. For a general discussion of CDGs, see CDG Ia (212065) and CDG Ib
(602579).;
Inheritance : Autosomal recessive;
Molecular basis : Caused by mutation in the mannose-P-dolichol utilization defect 1 gene (MPDU1, 604041.0001);
Laboratory abnormalities : Type 1 hypoglycosylation pattern of serum transferrin; Accumulation of truncated oligosaccharides Man(5)GlcNAc2 and Man(9)GlcNAc(2);
