Reporting a Novel Disease Causing Variant in PGAP3 Associated With Hyperphosphatasia and Intellectual Disability: A Case Report and Comprehensive Literature Review

Molecular Genetics &Genomic Medicine, Volume 14, Issue 3, March 2026.
We report a novel homozygous pathogenic PGAP3 variant (c.202dupT; p.Cys68fs*2) in a child with hyperphosphatasia and severe neurodevelopmental impairment. Elevated alkaline phosphatase guided diagnosis, expanding the genotypic and phenotypic spectrum of PGAP3‐related HPMRS.

Insights into ALG3-CDG: A case study combining glycan profiling and genetic analysis

Molecular Genetics and Metabolism Reports
Congenital disorders of glycosylation (CDG) are a group of rare metabolic disorders caused by the defects in the glycosylation pathways of biomacromolecules leading to altered glycoprofiles in affected individuals. In this case study, we present a 3-year-

Mannose phosphate isomerase-congenital disorder of glycosylation leads to asymptomatic hypoglycemia

Molecular Genetics and Metabolism Reports
Background: Mannose phosphate isomerase deficiency-congenital glycosylation disorders (MPI-CDG) is a rare autosomal recessive disorder caused by pathogenic variants in the MPI gene and characterized by digestive, hepatic, and endocrine-related symptoms ...

Synaptic roles for phosphomannomutase type 2 in a new Drosophila congenital disorder of glycosylation disease model

Disease Models & Mechanisms, 2016
Congenital disorders of glycosylation (CDGs) constitute a rapidly growing family of human diseases resulting from heritable mutations in genes driving the production and modification of glycoproteins.

Phosphomannomutase 2-congenital disorder of glycosylation: exploring the role of N-glycosylation on the endocrine axes

Frontiers in Endocrinology
Congenital disorders of glycosylation (CDG) are a heterogeneous group of inborn errors of metabolism caused by impaired protein glycosylation. Among these, PMM2-CDG, caused by defective phosphomannomutase 2 activity and affecting protein N-glycosylation,

Protease-dependent defects in N-cadherin processing drive PMM2-CDG pathogenesis

JCI Insight, 2021
The genetic bases for the congenital disorders of glycosylation (CDG) continue to expand, but how glycosylation defects cause patient phenotypes remains largely unknown. Here, we combined developmental phenotyping and biochemical studies in a potentially

A zebrafish model of congenital disorders of glycosylation with phosphomannose isomerase deficiency reveals an early opportunity for corrective mannose supplementation

Disease Models & Mechanisms, 2013
SUMMARY Individuals with congenital disorders of glycosylation (CDG) have recessive mutations in genes required for protein N-glycosylation, resulting in multi-systemic disease. Despite the well-characterized biochemical consequences in these individuals,

Evolutionary rate covariation is pervasive between glycosylation pathways and points to potential disease modifiers.

PLoS Genetics
Mutations in glycosylation pathways, such as N-linked glycosylation, O-linked glycosylation, and GPI anchor synthesis, lead to Congenital Disorders of Glycosylation (CDG).

Clinical and whole-exome sequencing findings in two siblings from Hani ethnic minority with congenital glycosylation disorders

BMC Medical Genetics, 2019
Background PMM2-CDG, is the most common N-linked glycosylation disorder and subtype among all CDG syndromes, which are a series of genetic disorders involving the synthesis and attachment of glycoproteins and glycolipid glycans. The mutations of PMM2-CDG

PIGN c.776T>C (p.Phe259Ser) variant present in trans with a pathogenic variant for PIGN-congenital disorder of glycosylation: Bella-Noah syndrome

Heliyon
Glycosylation is the most common protein and lipid post-translational modification in humans. Congenital disorders of glycosylation (CDG) are characterized by both genetic and clinical heterogeneity, presenting multisystemic manifestations, and in most ...
