A Novel Multimodal LC-MS/MS Panel for the Comprehensive Diagnosis of Neurometabolic Disorders in CSF. [PDF]
ABSTRACT Metabolic testing of cerebrospinal fluid (CSF) is essential for early diagnosis of neurometabolic disorders. However, the large number of differential diagnoses, the phenotypic variance within a clinical picture, and the disease rarity complicate targeted metabolic diagnostics.

Emergency Management of Intoxication-Type Inherited Metabolic Disorders. [PDF]
ABSTRACT In many intoxication‐type inherited metabolic disorders, the accumulation of the toxic chemical can cause acute life‐threatening emergencies. Sometimes this is the inevitable consequence of a severe metabolic defect, but it is often triggered by catabolism.

Untargeted Metabolomics for Diagnosis, Monitoring, and Understanding the Pathophysiology of Inherited Metabolic Disorders. [PDF]
ABSTRACT Inherited metabolic disorders (IMDs) encompass a diverse and expanding group of rare diseases caused by genetic disruptions mainly in metabolic enzymes and transporters. Clinical diagnosis of IMDs presents significant challenges due to phenotypic heterogeneity, nonspecific symptoms, and the limited scope of current targeted biochemical assays ...

Neonatal Refractory Seizures and Hyperammonemia in a Neonate With ALDH7A1 Deficiency. [PDF]
ABSTRACT Pyridoxine‐dependent epilepsy (PDE) is a rare, autosomal recessive neurometabolic disorder characterized by intractable seizures responsive to pyridoxine. We present the case of an 11‐day‐old female neonate with a history of refractory multifocal seizures beginning on day three of life, accompanied by hepatomegaly, metabolic acidosis, elevated

Seizures and electroencephalographic findings in inborn errors of metabolism: Clues to differential diagnosis in the neonatal period, infancy, childhood and adolescence, and review of the literature. [PDF]
Abstract Although inborn errors of metabolism (IEM) are a rare cause of epilepsy, seizures are a common presentation in these disorders. Seizures in IEM are frequently refractory to conventional anti‐seizure medication and might warrant initiation of specific treatments based on vitamins or dietary modifications or provision of alternative substrates ...

Essential Oral Single Nutritional Therapy Products for Inherited Metabolic Diseases: Evidence and Consensus Assessment Using a Modified Delphi Method. [PDF]
ABSTRACT Nutritional therapy is critical in managing inherited metabolic diseases (IMDs), and includes specialized diets and single nutritional therapy products (sNTPs) such as vitamins, cofactors, and amino acids. Many sNTPs function as medicines, but are regulated as food (e.g., food supplements), which can limit access, reimbursement, and consistent

Astrocytes in Genetic Epilepsies: Supporting Actor or Key Player? [PDF]
Astrocytes contribute to the pathophysiology of acquired epilepsy. However, less is known about their contribution to genetic epilepsy syndromes which often exhibit frequent comorbidity with neurodevelopmental and psychiatric disorders. Epileptic seizures are also frequently present in neurodevelopmental disorders.

A novel mouse model for pyridoxine-dependent epilepsy due to antiquitin deficiency. [PDF]
AbstractPyridoxine-dependent epilepsy (PDE) is a rare autosomal recessive disease caused by mutations in the ALDH7A1 gene leading to blockade of the lysine catabolism pathway. PDE is characterized by recurrent seizures that are resistant to conventional anticonvulsant treatment but are well-controlled by pyridoxine (PN).

Abstract Seizures are common in neonates, but there is substantial management variability. The Neonatal Task Force of the International League Against Epilepsy (ILAE) developed evidence‐based recommendations about antiseizure medication (ASM) management in neonates in accordance with ILAE standards.

On pathways and blind alleys—The importance of biomarkers in vitamin B6‐dependent epilepsies
Abstract Over the past two decades, the field of vitamin B6‐dependent epilepsies has evolved by the recognition of a growing number of gene defects (ALDH7A1, PNPO, ALPL, ALDH4A1, PLPBP as well as defects of the glycosylphosphatidylinositol anchor proteins) that all lead to reduced availability of pyridoxal 5′‐phosphate, an important cofactor in ...
