We report a case of a newborn with Glutaric aciduria type II. Pregnancy was complicated by polyhidramnios and fetal bradycardia. Cardiomegaly was detected by fetal echocardiography. The baby was admitted to the Neonatal Intensive Care Unit of Chieti with respiratory distress syndrome immediately after delivery. He showed head and neck edema, micrognathia, paucity of movement, pronounced hypotonia, bilateral cryptorchidism, micropenis, small hands, skin hyperelasticity and joint hypermobility. Serum and urine analysis showed a fatty acid beta-oxidation disorder. He died at 7 days of age for cardiac arrest and autopsy showed marked hepatic and cardiac vacuolisation, lipid storage myopathy and glial cells vacuolisation. Based upon these findings, we speculate that this infant may be suffering from inborn metabolic disease.

Digital-Tier Strategy Improves Newborn Screening for Glutaric Aciduria Type 1.

Int J Neonatal Screen

Glutaric aciduria type 1 (GA1) is a rare inherited metabolic disease increasingly included in newborn screening (NBS) programs worldwide. Because of the broad biochemical spectrum of individuals with GA1 and the lack of reliable second-tier strategies, NBS for GA1 is still confronted with a high rate of false positives. In this study, we aim to increase the specificity of NBS for GA1 and, hence, to reduce the rate of false positives through machine learning methods.

Restricting lysine normalizes toxic catabolites associated with ALDH7A1 deficiency in cells and mice.

Electronic address:

Lysine metabolism converges at α-aminoadipic semialdehyde dehydrogenase (ALDH7A1). Rare loss-of-function mutations in ALDH7A1 cause a toxic accumulation of lysine catabolites, including piperideine-6-carboxylate (P6C), that are thought to cause fatal seizures in children unless strictly managed with dietary lysine reduction. In this study, we perform metabolomics and expression analysis of tissues from Aldh7a1-deficient mice, which reveal tissue-specific differences in lysine metabolism and other metabolic pathways.

December 2024

Department of Pediatric Metabolism and Nutrition, Medical Faculty, Ege University, Izmir, 35040, Turkey.

Unlabelled: Glutaric aciduria type 1 (GA1) is a rare metabolic disorder characterized by a deficiency in the enzyme glutaryl-CoA dehydrogenase. This study aims to present the clinical, biochemical, genetic, and neuroimaging findings of GA1 patients, emphasizing the importance of early detection and the potential benefits of incorporating GA1 into NBS programs. The demographic, clinical, and laboratory findings of GA1 patients were reviewed retrospectively.

The biochemical hallmark of D-2-hydroxyglutaric aciduria is brain accumulation of D-2-hydroxyglutaric acid (D2HG). Patients present predominantly neurological manifestations, whose pathogenesis is still unknown. Thus, we examined the impact of elevated brain levels of D2HG, induced by intracerebral injection of this metabolite in juvenile rats, on redox and mitochondrial homeostasis and histochemical landmarks in the cerebral cortex.
