Severity of effect considerations regarding the use of mutation as a toxicological endpoint for risk assessment: A report from the 8th International Workshop on Genotoxicity Testing (IWGT)

open access: yesEnvironmental and Molecular Mutagenesis, EarlyView.
Abstract Exposure levels without appreciable human health risk may be determined by dividing a point of departure on a dose–response curve (e.g., benchmark dose) by a composite adjustment factor (AF). An “effect severity” AF (ESAF) is employed in some regulatory contexts.

Critical Evaluation of Methods for the Identification of Aneugens

open access: yesEnvironmental and Molecular Mutagenesis, EarlyView.
ABSTRACT The genotoxic potential of chemicals must be evaluated in regulatory safety assessment settings, including but not limited to, the development of new pharmaceuticals, industrial chemicals, food and cosmetic ingredients, and agrochemicals. Initial assessment of the chromosome‐damaging potential of chemicals is often conducted in mammalian cells

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

open access: yesEpileptic Disorders, EarlyView.
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 ...

Inherited metabolic epilepsies–established diseases, new approaches

open access: yesEpilepsia Open, EarlyView.
Abstract Inherited metabolic epilepsies (IMEs) represent the inherited metabolic disorders (IMDs) in which epilepsy is a prevailing component, often determining other neurodevelopmental outcomes associated with the disorder. The different metabolic pathways affected by individual IMEs are the basis of their rarity and heterogeneity.

Genetic epilepsies with myoclonic seizures: Mechanisms and syndromes

open access: yesEpilepsia Open, EarlyView.
Abstract Genetic epilepsy with myoclonic seizures encompasses a heterogeneous spectrum of conditions, ranging from benign and self‐limiting forms to severe, progressive disorders. While their causes are diverse, a significant proportion stems from genetic abnormalities.
