Congenital disorder of glycosylation 1A
A form of congenital disorder of glycosylation, a multisystem disorder caused by a defect in glycoprotein biosynthesis and characterized by under-glycosylated serum glycoproteins. Congenital disorders of glycosylation result in a wide variety of clinical features, such as defects in the nervous system development, psychomotor retardation, dysmorphic features, hypotonia, coagulation disorders, and immunodeficiency. The broad spectrum of features reflects the critical role of N-glycoproteins during embryonic development, differentiation, and maintenance of cell functions. CDG1A is an autosomal recessive disorder characterized by a severe encephalopathy with axial hypotonia, abnormal eye movement, and pronounced psychomotor retardation, as well as peripheral neuropathy, cerebellar hypoplasia, and retinitis pigmentosa. Patients show a peculiar distribution of subcutaneous fat, nipple retraction, and hypogonadism.

Exploring Secondary Biotinidase Deficiency and Biotin Supplementation in PMM2-CDG.
The congenital disorders of glycosylation (CDG) encompass >190 multiorgan disorders with predominantly neurodevelopmental phenotypes with no causative treatment available. The glycoprotein biotinidase (BTD) provides biotin, an essential cofactor for carboxylases in ubiquitous metabolic pathways. Individuals with (partial) BTD deficiency (BTDD) and CDG patients show overlapping phenotypes like movement disorders, seizures, and neurodevelopmental issues. Biotin is a water-soluble, inexpensive, and safe food supplement. Patients with primary BTDD respond well to oral biotin supplement. We here explore secondary BTDD and the effect of biotin supplementation in PMM2-CDG in an initial open-label study.BTD activity in dried blood spots from 29 individuals with PMM2-CDG indicated a mean reduction to 27% (range: 23.0-40.5%) at group level. Patients (mean: 19.6 ± 11.9 years) were supplemented with 10 mg biotin daily for 12 months. The parents/caretaker reported positive responses in 62 to 69% of patients across seven (performance, social, at home, self-control, self-care, leisure, health) of the nine categories covered by the Adaptive Behavior Assessment System-II (ABAS-II) questionnaires. The reported positive effect of biotin supplementation differed between age groups, ranging from 54% (16-43 years) via 62% (2-5 years) to 80% (6-13 years). Its effect was reported to be the highest in the moderate to severely affected patient subgroups, with significant improvements in home functioning, health, performance, leisure, self-control. No adverse effects were reported.Given the absence of other treatments, the supportive effect of Biotin in PMM2-CDG deserves further exploration.
Unilateral Multicystic Dysplastic Kidney in a Fetus Associated With Parental Genetic and Environmental Risk Factors: A Case Report.
Multicystic dysplastic kidney (MCDK) is a congenital renal anomaly identified on prenatal ultrasound. They often arise sporadically and unilaterally. Our case involves an isolated unilateral MCDK in a fetus born to a mother with generalized anxiety disorder (GAD), obsessive-compulsive disorder (OCD), and gastroesophageal reflux disease (GERD), with the father having chronic occupational lead exposure and a congenital disorder of glycosylation type 1A (PMM2-CDG). Our case highlights the multifactorial etiology of renal dysplasia and its potential role of glycosylation defects and environmental toxicity in abnormal kidney development. Contributions from genetic, environmental, and metabolic influences during nephrogenesis contribute to MCDK.
A founder variant in Tunisian PMM2-CDG patients: An integrated clinical, radiological, biochemical, and genetic study.
PMM2-CDG is the most common congenital disorder of glycosylation, characterized by a broad phenotypic spectrum involving the nervous system and multiple other organ systems. The disorder is caused by biallelic variants in the PMM2 gene, leading to impaired glycosylation of proteins. Our objective was to provide a detailed clinical characterization and define the mutational spectrum of PMM2-CDG in the Tunisian population. We conducted a retrospective study on patients with genetically confirmed PMM2-CDG, followed between 2005 and 2024. Ten patients from six unrelated Tunisian families were enrolled. All presented with neurological symptoms, including psychomotor delay (10/10), cerebellar ataxia (9/10) and strabismus (9/10). Brain MRI revealed cerebellar atrophy in all patients. Dysmorphic features were common including almond-shaped eyes (9/10), large mouth (6/10), and thin upper lip (6/10). Skeletal anomalies were observed in 9/10 patients. Peripheral neuropathy was confirmed in 6/7 patients. Laboratory analyses revealed elevated transaminases (6/10), hypocholesterolemia (7/10), elevated LDH (7/10), hypoalbuminemia (2/6), and IgA deficiency (3/5). Renal anomalies included hyperechogenicity (2/9) and a duplicated collecting system (1/9). Genetic analysis revealed a homozygous variant NM_000303.3(PMM2): c.395 T > C; p.(Ile132Thr) in all patients. Haplotype analysis of the PMM2 locus showed that all 6 families shared an identical allele. In conclusion, this is the first study to characterize the clinical and genetic profile of PMM2-CDG in the Tunisian population. Despite a shared genotype, patients exhibited moderate neurological phenotypes with inter- and intrafamilial variability. The recurrent homozygous c.395 T > C; p.(Ile132Thr) variant and identical haplotype confirm a founder effect in the Tunisian population.
Albumin as a glycoprotein biomarker in congenital disorders of glycosylation.
Congenital disorders of glycosylation (CDG) are rare inherited disorders resulting from defects in cellular glycosylation machinery. Albumin has recently been shown to be N-glycosylated at two non-canonical glycosylation sites. We applied multiplexed mass spectrometry-based glycoproteomics to identify site-specific N-glycosylation alterations in albumin from patients with PMM2-CDG, MPI-CDG, SRD5A3-CDG, MAN1B1-CDG and PGM1-CDG. Our findings demonstrate that the glycosylation of albumin is indeed affected in CDG and indicate a potential role for albumin-derived glycopeptides as diagnostic biomarkers.
PMM2-CDG and the Role of Liver Transplantation as a Long-Term Solution: A Case Report.
Phosphomannomutase-2 congenital disorder of glycosylation (PMM2-CDG) is the most common congenital disorder of glycosylation, affecting protein glycosylation across multiple organ systems. Hepatic involvement may range from isolated elevations in liver transaminases to end-stage liver disease. Reported outcomes of liver transplantation as a treatment modality are sparse. We describe one of the first reported cases of liver transplantation in a child with PMM2-CDG and interim post-transplant outcomes. This patient was diagnosed at 4 months of age after presenting with failure to thrive, lipodystrophy, hypotonia, developmental delay, elevated transaminases, hypoalbuminemia, and coagulopathy. He developed cirrhosis and portal hypertension as well as sequelae of poor protein glycosylation. All these included coagulopathy, protein-losing enteropathy, and refractory ascites requiring serial intravenous fresh frozen plasma and furosemide. He ultimately underwent a liver transplant, after which his ascites resolved. Post-transplant, he developed new-onset recurrent pericardial effusions, suspected to be from a viral etiology versus extrahepatic manifestations of PMM2-CDG, and elevated transaminases following transplantation. Liver transplantation may offer clinical benefit in PMM2-CDG with severe hepatic involvement, including resolution of ascites and improved quality of life, due to its potential to restore liver glycosylation function. However, this is only a partial correction as persistent extrahepatic manifestations underscore the need for further research into transplant outcomes and systemic disease progression in CDG.
