IMD Research Round-Up: Congenital Disorders of Glycosylation

JIMD Podcasts

Dr Matthew Wilson, Postdoctoral Fellow at the Centre for Human Genetics, KU Leuven, joins hosts Silvia Radenkovic and Rodrigo Starosta to discuss a scintillating selection of CDG papers in our first ever research round-up. Authors opinions are their own and do not represent their institutions. The papers discussed include: A pseudoautosomal glycosylation disorder prompts the revision of dolichol biosynthesis. Wilson et al Clinical and biochemical footprints of congenital disorders of glycosylation: Proposed nosology. Ng et al Rft1 catalyzes lipid-linked oligosaccharide translocation across the ER membrane. Chen et al Molecular characterization of Rft1, an ER membrane protein associated with congenital disorder of glycosylation RFT1-CDG. Hirata et al Genome and RNA sequencing were essential to reveal cryptic intronic variants associated to defective ATP6AP1 mRNA processing. Morales-Romero et al N-glycoproteomic and proteomic alterations in SRD5A3-deficient fibroblasts. Garapati et al In vitro treatment with liposome-encapsulated Mannose-1-phosphate restores N-glycosylation in PMM2-CDG patient-derived fibroblasts. Shirakura et al Liposome-encapsulated mannose-1-phosphate therapy improves global N-glycosylation in different congenital disorders of glycosylation. Budhraja et al D-mannose as a new therapy for fucokinase deficiency-related congenital disorder of glycosylation (FCSK-CDG). Starosta et al Glycoproteomics in Cerebrospinal Fluid Reveals Brain-Specific Glycosylation Changes.
