Congenital disorders of glycosylation (CDG)
Congenital Disorders of Glycosylation (CDG) comprise permanently expanding group of inherited diseases caused by defects of multiple glycosylation pathways which disturb structure of many glycoconjugates classes. The first patients were described by Jaak Jaeken in 1980, in 1984 simple test was implemented to identify new cases. In 1995, fifteen years later, enzymatic defect was revealed as phos...
متن کاملNutritional Therapies in Congenital Disorders of Glycosylation (CDG)
Congenital disorders of glycosylation (CDG) are a group of more than 130 inborn errors of metabolism affecting N-linked, O-linked protein and lipid-linked glycosylation. The phenotype in CDG patients includes frequent liver involvement, especially the disorders belonging to the N-linked protein glycosylation group. There are only a few treatable CDG. Mannose-Phosphate Isomerase (MPI)-CDG was th...
متن کاملAlkynyl monosaccharide analogues as a tool for evaluating Golgi glycosylation efficiency: application to Congenital Disorders of Glycosylation (CDG).
The visualization of Golgi glycosylation defects in patients' cells with Congenital Disorders of Glycosylation (CDG) is challenging and necessitates the use of cumbersome glycan analysis methods that are barely adapted to clinical research. We show here that metabolic labelling of patient cells with alkyne-tagged sialic-acid (SiaNAl) enables an easy and reliable readout assay for the detection ...
متن کاملCongenital disorder of glycosylation type Ij (CDG-Ij, DPAGT1-CDG): extending the clinical and molecular spectrum of a rare disease.
Congenital disorders of glycosylation (CDG) are caused by enzymatic defects of the formation or processing of lipid-linked oligosaccharides and glycoproteins. Since the majority of proteins is glycosylated, a defect in a singular CDG enzyme leads to a multisytemic disease with secondary malfunction of thousands of proteins. CDG-Ij (DPAGT1-CDG) is caused by a defect of the human DPAGT1 (UDP-GlcN...
متن کاملIdentification of four novel PMM2 mutations in congenital disorders of glycosylation (CDG) Ia French patients.
We screened 11 unrelated French patients with congenital disorders of glycosylation (CDG) Ia for PMM2 mutations. Twenty one missense mutations on the 22 chromosomes (95%) including four novel mutations were identified: C9Y (G26A) in exon 1, L32R (TA95GC) in exon 2, and T226S (C677G) and C241S (G722C) in exon 8. We studied the PMM activity of these four novel mutant proteins and of the R141H mut...
