[A case of L-2-hydroxyglutaric aciduria diagnosed with involuntary movements, in which improvement in motor symptoms was achieved following treatment].

Rinsho shinkeigaku = Clinical neurology2025 Feb 21

A 49-year-old female presented with the primary complaint of hand tremors. Neurological examination on admission revealed signs of cognitive impairment, bulbar palsy, dystonia, cerebellar ataxia, and pyramidal tract disease. T2-weighted brain MRI revealed hyperintense signals in the subcortical white matter, basal ganglia, and cerebellar dentate nucleus, with no atrophy of the brainstem or corpus callosum. Urinary organic acid analysis revealed elevated 2-hydroxyglutaric acid levels. Although the optical isomers could not be distinguished, L-2-hydroxyglutaric aciduria was diagnosed based on the disease course, symptoms, and characteristic MRI findings. The patient was started on riboflavin-enriched compounds and levocarnitine, resulting in an improvement in the Scale for the Assessment and Rating of Ataxia (SARA) score from 21 to 15 after six months. The case suggests that symptoms in adult patients who have not been treated for a long time can be improved by appropriate diagnosis based on neurological presentation, characteristic MRI findings, and intervention.

Inactivation of the SLC25A1 gene during embryogenesis induces a unique senescence program controlled by p53.

Cell death and differentiation2025 May

Germline inactivating mutations of the SLC25A1 gene contribute to various human disorders, including Velocardiofacial (VCFS), DiGeorge (DGS) syndromes and combined D/L-2-hydroxyglutaric aciduria (D/L-2HGA), a severe systemic disease characterized by the accumulation of 2-hydroxyglutaric acid (2HG). The mechanisms by which SLC25A1 loss leads to these syndromes remain largely unclear. Here, we describe a mouse model of SLC25A1 deficiency that mimics human VCFS/DGS and D/L-2HGA. Surprisingly, inactivation of both Slc25a1 alleles results in alterations in the development of multiple organs, and in a severe proliferation defect by activating two senescence programs, oncogene-induced senescence (OIS) and mitochondrial dysfunction-induced senescence (MiDAS), which converge upon the induction of the p53 tumor suppressor. Mechanistically, cells and tissues with dysfunctional SLC25A1 protein undergo metabolic and transcriptional rewiring leading to the accumulation of 2HG via a non-canonical pathway and to the depletion of nicotinamide adenine dinucleotide, NAD+, which trigger senescence. Replenishing the pool of NAD+ or promoting the clearance of 2HG rescues the proliferation defect of cells with dysfunctional SLC25A1 in a cooperative fashion. Further, removal of p53 activity via RNA interference restores proliferation, indicating that p53 acts as a critical barrier to the expansion of cells lacking functional SLC25A1. These findings reveal unexpected pathogenic roles of senescence and of p53 in D/L-2HGA and identify potential therapeutic strategies to correct salient molecular alterations driving this disease.

A Pathogenic L2HGDH Variant Impairs Mitochondrial Targeting and Enzyme Function in L-2-Hydroxyglutaric Aciduria: Clinical and Functional Evidence from Two Affected Siblings.

Genes2025 Aug 20

L-2-hydroxyglutaric aciduria (L2HGA) is a rare autosomal recessive neurometabolic disorder caused by biallelic loss-of-function variants in the L-2-hydroxyglutarate dehydrogenase (L2HGDH) gene, leading to accumulation of L-2-hydroxyglutarate in the brain and other tissues. While various variants have been reported, the pathogenic mechanism of specific variants remains unclear. In this study, we aimed to investigate the molecular consequences of the c.905C>T p.(Pro302Leu) variant, identified in two siblings with typical symptoms of L2HGA, by analyzing its effects on protein localization and enzymatic activity in a cell model. HA-tagged wild-type and p.(Pro302Leu) mutant L2HGDH constructs were overexpressed in HEK293T cells. We assessed protein expression, subcellular localization, and enzymatic activity using Western blot analysis, immunofluorescence microscopy, and a specific enzyme assay measuring 2,6-dichloroindophenol (DCIP) reduction to assess L2HGDH enzymatic activity. Western blotting showed that wild-type L2HGDH exists primarily in the processed, mature mitochondrial form, whereas the p.(Pro302Leu) mutant remained largely in the unprocessed precursor form. Immunofluorescence and differential centrifugation revealed that wild-type protein localized to mitochondria, while the mutant protein accumulated in the cytoplasm in a diffuse or punctate pattern. Enzyme activity assays demonstrated that the mutant retained <30% of wild-type activity. These findings indicate that the p.(Pro302Leu) variant leads to aggregation of mislocalized protein, thereby impairing L2HGDH function rather than decreasing enzymatic function. This study provides clinical and molecular evidence supporting the pathogenicity of this previously reported mutation and highlights the importance of mitochondrial import for enzyme functionality in L2HGA.

Genetic, neuroimaging, and clinical characteristics of a cohort of individuals with L-2-hydroxyglutaric aciduria from Türkiye.

Journal of pediatric endocrinology &amp; metabolism : JPEM2025 Sep 25

L-2-hydroxyglutaric aciduria (L2HGA) is a hereditary metabolic disorder characterized by the accumulation of L-2-hydroxyglutaric acid in body fluids, particularly in cerebrospinal fluid, which disrupts neuron function in the central nervous system and triggers oxidative stress. It can cause seizures, developmental disorders, and behavioral abnormalities. The study retrospectively evaluated the demographic information, initial symptoms, clinical characteristics, cranial magnetic resonance imaging (MRI) findings, and post-treatment biochemical changes of 10 cases diagnosed with L2HGA. The study included five paediatric and five adult cases with a molecular diagnosis of L2HGA. The mean age at diagnosis was 10.1 years. Convulsion was identified as the primary presenting symptom in 70 % of cases. We identified intellectual disability in 80 % of our cases. In addition to the classic cranial MRI findings of subcortical white matter involvement, basal ganglia involvement was detected in 60 % of cases. We found that 2-hydroxyglutaric acid levels in urine organic acid analysis were significantly decreased riboflavin and carnitine post-treatment, with a mean decrease of 133.89 ± 101.43 mmol/mol creatinine (p=0.017). The most common missense variant identified in the L2HGDH gene was c.905C>T (p.Pro302Leu), occurring at a frequency of 50 % (5/10). The cases did not report significant improvement in their symptoms with treatment. L2HGA is a rare metabolic disorder that is more common in communities where consanguineous marriages are prevalent. Early diagnosis enables early treatment and protection of the brain from oxidative stress. As more cases are reported publicly, studies on genotype-phenotype relationships will yield more significant findings.

Riboflavin treatment in L-2-hydroxyglutaric aciduria: report on a pediatric patient and literature review.

Journal of applied genetics2025 May 17

L-2-hydroxyglutaric aciduria (L-2-HGA, #236,792) is an autosomal recessive neurodegenerative disorder caused by the deficiency of L-2-hydroxyglutarate dehydrogenase, a flavin adenine dinucleotide (FAD)-dependent enzyme, due to biallelic pathogenic variants in the L2HGDH gene. The present study described the patient with L2HGA presenting with a slight psychomotor delay, epilepsy from 5 years of age, non-progressive cerebellar ataxia, and mild to moderate intellectual disability during 10 years of follow-up. Two different heterozygous variants in the L2HGDH gene were identified in the patient: a known substitution c.829C > T(p.Arg277*) and a novel substitution c.1196 + 1G > A corresponding with significantly increased urinary L-2-hydroxyglutarate (L2HG) excretion. A 6-month period of treatment with riboflavin (100 mg/day) was implemented with no clinical nor biochemical effect.
