Interpretation of in vitro concentration‐response data for risk assessment and regulatory decision‐making: Report from the 2022 IWGT quantitative analysis expert working group meeting

Environmental and Molecular Mutagenesis, EarlyView.
Abstract Quantitative risk assessments of chemicals are routinely performed using in vivo data from rodents; however, there is growing recognition that non‐animal approaches can be human‐relevant alternatives. There is an urgent need to build confidence in non‐animal alternatives given the international support to reduce the use of animals in toxicity ...

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)

Environmental 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.

TUBA1A‐related tubulinopathy associated with the infantile epileptic spasms syndrome and atypical absence seizures

Epileptic Disorders, EarlyView.
Abstract Patients with TUBA1A pathogenic variants may present with complex brain malformation, intellectual disability, and epilepsy. The epilepsy phenotype is varied, ranging from mild to severe, with epileptic spasms and focal seizures being the most common seizure types.

Genetic epilepsies with myoclonic seizures: Mechanisms and syndromes

Epilepsia 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.

Precision therapies for genetic epilepsies in 2025: Promises and pitfalls

Epilepsia Open, EarlyView.
Abstract By targeting the underlying etiology, precision therapies offer an exciting paradigm shift to improve the stagnant outcomes of drug‐resistant epilepsies, including developmental and epileptic encephalopathies. Unlike conventional antiseizure medications (ASMs) which only treat the symptoms (seizures) but have no effect on the underlying ...

The challenge of ultra‐rarity: Dual diagnosis of Lafora disease and developmental encephalopathies linked to TRIO and SHANK3 pathogenic variants

Epilepsia Open, EarlyView.
Abstract We report two cases of dual genetic diagnoses involving Lafora disease (LD) and co‐occurring neurodevelopmental disorders caused by pathogenic variants in TRIO and SHANK3, respectively. LD is an ultra‐rare, autosomal recessive, severe form of progressive myoclonus epilepsy affecting previously healthy children or adolescents. In both patients,

The multiple hit model of infantile and epileptic spasms: The 2025 update

Epilepsia Open, EarlyView.
Abstract Objective Infantile and epileptic spasms syndrome (IESS) is a developmental and epileptic encephalopathy manifesting with epileptic spasms and poor neurodevelopmental outcomes. There is an urgent need for the development of more effective and tolerated therapies.
