Genetic testing among patients evaluated for epilepsy surgery

open access: yesEpileptic Disorders, EarlyView.
Abstract Objective Genetic testing performed to identify the underlying etiology of epilepsy has become increasingly common and is now being recommended as part of the presurgical evaluation for epilepsy surgery. This study aimed to characterize the types of genetic tests performed in patients evaluated for epilepsy surgery and assess how genetic ...

Epilepsy‐associated SCN2A‐L1342P mutation drives network hyperexcitability and widespread transcriptomic changes in human cortical organoids

open access: yesEpilepsia, EarlyView.
Abstract Objective SCN2A pathogenic mutations, such as the recurrent heterozygous Nav1.2‐L1342P, are monogenic causes of epilepsy. In this human‐induced pluripotent stem cell–derived model system, we aim to investigate the molecular and cellular mechanisms underlying SCN2A‐L1342P‐associated pathology. Methods Using a human male induced pluripotent stem

Oligogenic inheritance in epilepsy: A systematic exome‐wide analysis

open access: yesEpilepsia, EarlyView.
Abstract Objective Genetic factors contribute to the majority of epilepsies, but the exact genetic cause remains unknown in most patients. Incomplete penetrance and variable expressivity are frequent, and recent studies showed a burden of deleterious variants in epilepsy genes, suggesting a role for oligogenic inheritance.

Early-Onset Cerebellar Atrophy Associated With Mutation in the CACNA1A Gene

open access: yes, 2011
Mutations in the CACNA1A gene were described in familial hemiplegic migraine, episodic ataxia type 2, and spinocerebellar ataxia type 6. Familial hemiplegic migraine and episodic ataxia type 2 are caused by point mutations in the CACNA1A gene, and ...

Absence seizures: Update on signaling mechanisms and networks

open access: yesEpilepsia Open, EarlyView.
Abstract Absence seizures (AS) are a hallmark of genetic generalized epilepsies (GGE), characterized by brief episodes of impaired consciousness accompanied by electroencephalographic spike‐and‐wave discharges (SWDs). Traditionally attributed to cortico‐thalamo‐cortical (CTC) dysrhythmia, emerging evidence suggests a more intricate pathophysiological ...

Artificial intelligence in preclinical epilepsy research: Current state, potential, and challenges

open access: yesEpilepsia Open, EarlyView.
Abstract Preclinical translational epilepsy research uses animal models to better understand the mechanisms underlying epilepsy and its comorbidities, as well as to analyze and develop potential treatments that may mitigate this neurological disorder and its associated conditions. Artificial intelligence (AI) has emerged as a transformative tool across

A neurodevelopmental disorder caused by a dysfunctional CACNA1A allele

open access: yeseNeurologicalSci, 2023
P/Q-type Ca2+ flux into nerve terminals via CaV2.1 channels is essential for neurotransmitter release at neuromuscular junctions and nearly all central synapses.

The genetic architecture of epilepsy across molecular mechanisms and clinical heterogeneity

open access: yesEpilepsia Open, EarlyView.
Abstract Epilepsy comprises a highly heterogeneous group of neurological disorders unified by a persistent predisposition to recurrent seizures, yet driven by remarkably diverse genetic, molecular, and network‐level mechanisms. Advances in genomic technologies have revealed that epilepsy arises from a multilayered genetic architecture encompassing rare

Phenotype‐guided etiologic workup in a prospective cohort of 144 adults with developmental and epileptic encephalopathy

open access: yesEpilepsia Open, EarlyView.
Abstract Objectives Adults with developmental and epileptic encephalopathies (DEEs) often enter adult neurology care without etiologic clarification because of incomplete transition from pediatric services, outdated investigations, and attenuation of childhood electro‐clinical features over time.

Rare genetic variation in adults with surgically treated temporal lobe epilepsy: An exome sequencing study

open access: yesEpilepsia Open, EarlyView.
Abstract Objective To determine the frequency of monogenic variants and pathogenic copy number variants (CNVs) in adults with surgically treated temporal lobe epilepsy (TLE). Methods We performed exome sequencing (ES), including CNV analysis, in 45 adults with TLE who had previously undergone epilepsy surgery.
