Congenital disorder of glycosylation, type ij - CISMeF
Congenital disorder of glycosylation, type ijOMIM Phenotype
Preferred Label : Congenital disorder of glycosylation, type ij;
Symbol : CDG1J;
CISMeF acronym : CDG1J;
Type : Phenotype, molecular basis known;
Alternative titles and symbols : CDGIj; Cdg ij;
Description : Like all CDGs, which are caused by a shortage of precursor monosaccharide phosphate
or deficiencies in the glycosyltransferases required for lipid-linked oligosaccharide
precursor (LLO) synthesis, CDG Ij is caused by a defect in the formation of DPAGT1,
the first dolichyl-linked intermediate of the protein N-glycosylation pathway. For
a general discussion of CDGs, see CDG1A (212065).;
Inheritance : Autosomal recessive;
Molecular basis : Caused by mutation in the dolichyl-phosphate N-acetylglucosamine phosphotransferase
gene (DPAGT1, 191350.0001);
Laboratory abnormalities : Abnormal liver enzymes (in 1 patient); Hypoproteinemia (in 1 patient); Abnormal isoelectric focusing of serum transferrin (type 1 pattern);
