PIGO‐CDG: A case study with a new genotype, expansion of the phenotype, literature review, and nosological considerations

JIMD Reports, 2023
The phosphatidylinositol glycan anchor biosynthesis class O protein (PIGO) enzyme is an important step in the biosynthesis of glycosylphosphatidylinositol (GPI), which is essential for the membrane anchoring of several proteins.

Evolutionary divergence and functional insights into the heteromeric cis‐prenyltransferase of Paramecium tetraurelia

The FEBS Journal, Volume 293, Issue 6, Page 1681-1707, March 2026.
Heteromeric cis‐prenyltransferases (CPT) are indispensable for dolichol synthesis and protein N‐glycosylation in most eukaryotes. The catalytic subunits are strongly conserved throughout evolution, in contrast to the evolutionarily variable accessory subunits. The POC1 protein from Paramecium tetraurelia is the smallest identified CPT‐accessory subunit

An OGT Missense Variant With Impaired Enzyme Activity in a Child With Severe Developmental Delay and Hepatoblastoma

American Journal of Medical Genetics Part A, Volume 200, Issue 2, Page 502-510, February 2026.
ABSTRACT O‐GlcNAc transferase (OGT) and its antagonist O‐GlcNAcase (OGA) regulate protein O‐GlcNAcylation, a highly conserved post‐translational modification involved in metabolic sensing. Pathogenic variants in the OGT gene cause an X‐linked congenital disorder of glycosylation (OGT‐CDG) presenting developmental delay, hypotonia, intellectual ...

Olig2‐specific loss‐of‐function Slc35a2 results in hypomyelination and spontaneous seizures

Epilepsia, Volume 67, Issue 2, Page 950-965, February 2026.
Abstract Objective Malformations of cortical development represent major causes of drug‐resistant epilepsy, with mild malformation of cortical development with oligodendroglial hyperplasia and epilepsy recognized as a distinct pathological entity. Pathogenic X‐linked SLC35A2, encoding the uridine diphosphate–galactose transporter, has been implicated ...

Bacterial lipid II analogs : novel in vitro substrates for mammalian oligosaccharyl diphosphodolichol diphosphatase (DLODP) activities [PDF]

, 2019
Mammalian protein N-glycosylation requires the transfer of an oligosaccharide containing 2 residues of N-acetylglucosamine, 9 residues of mannose and 3 residues of glucose (Glc3Man9 GlcNAc2) from Glc3Man9GlcNAc2-diphospho (PP)-dolichol (DLO) onto ...

Untargeted Metabolomics for Diagnosis, Monitoring, and Understanding the Pathophysiology of Inherited Metabolic Disorders

Journal of Inherited Metabolic Disease, Volume 49, Issue 1, January 2026.
ABSTRACT Inherited metabolic disorders (IMDs) encompass a diverse and expanding group of rare diseases caused by genetic disruptions mainly in metabolic enzymes and transporters. Clinical diagnosis of IMDs presents significant challenges due to phenotypic heterogeneity, nonspecific symptoms, and the limited scope of current targeted biochemical assays ...
