Metabolic Stroke: Atypical Presentation of Succinic Semialdehyde Dehydrogenase Deficiency.

JIMD reports2026 Mar

Succinic semialdehyde dehydrogenase (SSADH) deficiency is a rare autosomal recessive neurometabolic disorder caused by biallelic pathogenic variants in ALDH5A1, encoding the mitochondrial enzyme SSADH. This enzyme catalyses the conversion of succinic semialdehyde to succinic acid in the γ-aminobutyric acid (GABA) degradation pathway. SSADH deficiency leads to the accumulation of neurotoxic metabolites, including γ-hydroxybutyrate (GHB), and presents with developmental delay, hypotonia, ataxia, seizures, behavioral disturbances, and intellectual disability. We report a 10-month-old Caucasian male with global developmental delay, central hypotonia, and delayed motor milestones. He presented acutely with left-sided hemiplegia following irritability and vomiting. Brain MRI showed bilateral (right > left) T2 hyperintensities and diffusion restriction in the globus pallidus. Urine organic acid analysis via gas chromatography-mass spectrometry revealed markedly elevated 4-hydroxybutyric acid and 4,5-dihydroxyhexanoic lactone, pathognomonic for SSADH deficiency. Molecular testing identified compound heterozygous ALDH5A1 variants: c.278G>T p.(Cys93Phe) and c.612G>A p.(Trp204*), both previously reported as pathogenic. Parental segregation confirmed trans configuration. Three weeks postillness, he developed focal seizures, which have remained well controlled on levetiracetam. His seizure onset in infancy is notably earlier than the typical early childhood onset (~9 years) reported in SSADH deficiency. This case expands the phenotypic spectrum of SSADH deficiency to include metabolic stroke as a presenting feature in infancy and highlights the importance of early recognition and molecular confirmation to guide management and emerging therapeutic strategies.

Treatable and preventable causes of inborn errors of metabolism: Cohort of neurotransmitter disorders in children from India.

Brain &amp; development2025 Oct

Neurotransmitter disorders are a group of heterogeneous conditions that comprise defects in synthesis, transport, receptor binding, and degradation of neurochemical messengers. These rare disorders range from mild intermittent dystonia to lethal encephalopathies. The natural history and clinical presentation remain far from established. The study was conducted between October 2015 and September 2024. This study aims to describe the spectrum of clinical presentation, laboratory, imaging features, and genetic profiles of children diagnosed with neurotransmitter disorders and to assess the treatment modalities and clinical outcomes in these children. Among 29 patients, the median age was 12 months, with a male predominance. Positive family history was noted in 9 cases. The most frequent presentation was global developmental delay (GDD), dystonia, and seizures with autonomic disturbances, with diurnal variation. Various subcategories of neurotransmitter disorders are aromatic L amino acid decarboxylase deficiency-7 cases, tyrosine hydroxylase deficiency-3 cases, dopamine transporter deficiency syndrome-1 case, vesicular monoamine transporter 2 deficiency (VMAT2)-2 cases, GTP cyclohydrolase type deficiency-1 case, 6-pyruvoyl-tetrahydropterin synthase deficiency-1 case, dihydropteridine reductase deficiency-3, sepiapterin reductase deficiency-1 case, glycine encephalopathy-1 case, FOLR1-related cerebral folate transport deficiency-3 cases, and succinic semialdehyde dehydrogenase deficiency-5 cases. Metabolic workups were normal in all cases, with elevated phenylalanine levels in tandem mass spectrometry (TMS) in 5 children. Neuroimaging and electroencephalogram (EEG) were abnormal in 7 and 5 children, respectively. Multi-pronged and early treatment ensured better outcomes in these children. The most common type of neurotransmitter disorder in our series was aromatic L-amino acid decarboxylase deficiency, with the most common presentation being global developmental delay and dystonia.

Central Dysmyelination in SSADH-Deficient Humans and Mice.

Annals of clinical and translational neurology2025 Nov

Succinic semialdehyde dehydrogenase deficiency (SSADHD) is an inherited metabolic disorder characterized by an accumulation of γ-aminobutyric (GABA). In addition to its synaptic role as an inhibitory neurotransmitter, GABA also plays an important role in myelination. We aimed to investigate the relationship between GABA and myelination abnormalities in SSADHD patients and the mouse model. Brain MRIs performed on 44 individuals (23 with SSADHD and 21 healthy controls) were independently reviewed by two neuroradiologists and scored using a disease-specific myelination scoring system. Inter-rater reliability (IRR) was assessed by the intraclass correlation coefficient. Myelination scores of SSADHD individuals were correlated with clinical, biochemical, magnetic resonance spectroscopy, and genetic data. Additionally, we investigated the expression of myelin-related genes in a mouse SSADHD model. Dysmyelination in SSADHD patients was overall mild, but significantly greater than in healthy controls (p < 0.001). In SSADHD patients, lower myelination scores were significantly correlated with younger age (R = 0.775, p < 0.001) and higher plasma GABA (R = -0.722, p < 0.001) and γ-hydroxybutyric acid (GHB) (R = -0.683, p = 0.001). In SSADH-deficient mice, there was reduced expression of genes encoding myelin basic protein (p = 0.001), myelin-associated oligodendrocyte basic protein (p = 0.001), and mitochondrial aspartate transporter (p = 0.025). Excessive GABA and GHB, which characterize SSADHD and are further pronounced in younger SSADHD individuals, may account for delayed oligodendrocyte maturation and altered myelination dynamics in this disorder. Studying the properties of dysmyelination in this unique disorder enhances our understanding of GABA's mediating role on myelination and may contribute to monitoring disease progression and managing other white-matter neurological disorders.

A crucial active site network of titratable residues guides catalysis and NAD+ binding in human succinic semialdehyde dehydrogenase.

Protein science : a publication of the Protein Society2025 Jan

Human succinic semialdehyde dehydrogenase is a mitochondrial enzyme fundamental in the neurotransmitter γ-aminobutyric acid catabolism. It catalyzes the NAD+-dependent oxidative degradation of its derivative, succinic semialdehyde, to succinic acid. Mutations in its gene lead to an inherited neurometabolic rare disease, succinic semialdehyde dehydrogenase deficiency, characterized by mental and developmental delay. Due to the poor characterization of this enzyme, we carried out evolutionary and kinetic investigations to contribute to its functional behavior, a prerequisite to interpreting pathogenic variants. An in silico analysis shows that succinic semialdehyde dehydrogenases belong to two families, one human-like and the other of bacterial origin, differing in the oligomeric state and in a network of active site residues. This information is coupled to the biophysical-biochemical characterization of the human recombinant enzyme uncovering that (i) catalysis proceeds by an ordered bi-bi mechanism with NAD+ binding before the aldehyde that exerts a partial non-competitive inhibition; (ii) a stabilizing complex between the catalytic Cys340 and NAD+ is observed and interpreted as a protective mechanism; and (iii) a concerted non-covalent network assists the action of the catalytic residues Cys340 and Glu306. Through mutational analyses of Lys214, Glu306, Cys340, and Glu515 associated with pH studies, we showed that NAD+ binding is controlled by the dyad Lys214-Glu515. Moreover, catalysis is assured by proton transfer exerted by the same dyad networked with the catalytic Glu306, involved in catalytic Cys340 deprotonation/reprotonation. The identification of this weak bond network essential for cofactor binding and catalysis represents a first step to tackling the molecular basis for its deficiency.

Anesthetic Management of a Pediatric Patient With Succinic Semialdehyde Dehydrogenase Deficiency Undergoing Dental Procedures.

Case reports in anesthesiology2025

Succinic semialdehyde dehydrogenase deficiency is a rare autosomal recessive disorder of Gamma-aminobutyric acid metabolism characterized by neurological deficits and an increased risk of seizures. Patients with succinic semialdehyde dehydrogenase deficiency may present unique challenges in anesthesia management due to altered neurotransmitter levels and possible drug sensitivities. The literature is sparse regarding perioperative management of these patients. We present the case of a 7-year-old boy, who underwent dental procedures under general anesthesia, with genetically confirmed succinic semialdehyde dehydrogenase deficiency. Anesthesia was initiated by intravenous induction, and sevoflurane was used for maintenance, with careful use of intravenous midazolam and rocuronium. Local anesthetic (lidocaine with epinephrine) was administered. The procedure lasted 120 min and was uneventful. The patient recovered without complications and was discharged the same day. This case highlights the feasibility of sevoflurane-based anesthesia in patients with succinic semialdehyde dehydrogenase deficiency. Safe perioperative management can be achieved with individual anesthetic planning, careful drug selection, and appropriate monitoring. Documentation of similar cases is necessary to establish evidence-based anesthetic strategies in this rare patient population.
