AI Article Synopsis

  • Focal cortical dysplasia (FCD) has unclear mechanisms for causing seizures, and existing animal models do not effectively mimic these seizures.
  • Researchers used in utero electroporation to delete the DEPDC5 gene in the embryonic brains of rats, leading to spontaneous seizures that mirror the key features of FCD IIA.
  • This study enhances our understanding of the underlying causes of FCD and sets the stage for developing targeted treatments.

Article Abstract

Epileptogenic mechanisms in focal cortical dysplasia (FCD) remain elusive, as no animal models faithfully recapitulate FCD seizures, which have distinct electrographic features and a wide range of semiologies. Given that DEPDC5 plays significant roles in focal epilepsies with FCD, we used in utero electroporation with clustered regularly interspaced short palindromic repeats gene deletion to create focal somatic Depdc5 deletion in the rat embryonic brain. Animals developed spontaneous seizures with focal pathological and electroclinical features highly clinically relevant to FCD IIA, paving the way toward understanding its pathogenesis and developing mechanistic-based therapies. Ann Neurol 2018;83:140-146.

  • * A pathogenic variant was found in 31% of the total cases analyzed, with higher rates in specific conditions like focal cortical dysplasia type II (33%) and hemimegalencephaly (62%), particularly involving the mTOR signaling pathway.
  • * The identification of germline and somatic variants, especially in focal epilepsy genes, provides insights for future analyses on genetic factors related to surgical outcomes, which could enhance patient counseling and treatment plans.

Focal Cortical Dysplasia, Hemimegalencephaly and Cortical Tuber are pediatric epileptogenic malformations of cortical development (MCDs) frequently pharmaco-resistant and mostly surgically treated by the resection of epileptic cortex. Availability of cortical resection samples allowed significant mechanistic discoveries directly from human material. Causal brain somatic or germline mutations in the AKT/PI3K/DEPDC5/MTOR genes were identified.

Objective: This study investigates the prevalence of pathogenic variants in the mechanistic target of rapamycin (mTOR) pathway in surgical specimens of malformations of cortical development (MCDs) and cases with negative histology. The study also aims to evaluate the predictive value of genotype-histotype findings on the surgical outcome.

Methods: The study included patients with drug-resistant focal epilepsy who underwent epilepsy surgery.

Brain somatic mutations in various components of the mTOR complex 1 (mTORC1) pathway have emerged as major causes of focal malformations of cortical development and intractable epilepsy. While these distinct gene mutations converge on excessive mTORC1 signaling and lead to common clinical manifestations, it remains unclear whether they cause similar cellular and synaptic disruptions underlying cortical network hyperexcitability. Here, we show that in utero activation of the mTORC1 activator genes, or , or biallelic inactivation of the mTORC1 repressor genes, , , or in the mouse medial prefrontal cortex leads to shared alterations in pyramidal neuron morphology, positioning, and membrane excitability but different changes in excitatory synaptic transmission.
