The field of epilepsy research has been significantly transformed by advances in genomics. Genomics plays a growing role in diagnosing and managing various epilepsies, with genetic testing, including whole-exome and whole-genome sequencing, crucial for identifying underlying causes, guiding treatment, and offering prognostic information, particularly in pediatric and early-onset cases [1].
Genomic discoveries have profoundly reshaped our understanding of epilepsy, covering both monogenic forms and the complex polygenic architecture of common epilepsies. These genetic findings are increasingly vital for precise diagnosis, classification, and personalized treatment approaches, moving beyond traditional phenotyping [2].
Precision medicine in epilepsy has evolved dramatically, largely driven by these genomic advancements. Identifying specific genetic etiologies allows for targeted therapies, leading to improved seizure control and better management of comorbidities, though challenges in broad implementation, such as accessibility and interpretation of complex genetic data, persist [3].
The impact of genomics extends notably to epileptic encephalopathies, a severe group of epilepsies. Next-generation sequencing has enabled the identification of numerous causative genes, fostering a deeper understanding of disease mechanisms and paving the way for targeted therapies, even though many cases still lack a clear genetic diagnosis [4].
For clinicians, integrating genetic testing into epilepsy diagnosis and management is becoming standard practice. Practical guides cover different genetic testing modalities, result interpretation, and counseling considerations, emphasizing how genetic information refines diagnosis, predicts prognosis, and informs treatment decisions, especially for rare and complex epilepsy syndromes [5].
Beyond diagnosis, the landscape of novel genetic therapies for epilepsy is exciting and rapidly developing. Various approaches, including gene therapy, antisense oligonucleotides (ASOs), and CRISPR/Cas9-based strategies, offer potential to address underlying genetic defects and provide precise, disease-modifying treatments for previously intractable forms of epilepsy [6].
Tracing the historical progress and current trajectory of epilepsy genetics reveals a journey from the initial discovery of single epilepsy genes to the current era of high-throughput sequencing and the promise of personalized medicine. These genetic insights are fundamentally transforming epilepsy classification, prognosis, and the development of targeted therapies [7].
Contemporary methods for genetic diagnosis in epilepsy encompass gene panels, exome sequencing, and emerging whole-genome sequencing. Reviews discuss the diagnostic yield, interpretation challenges, and the critical importance of integrating clinical phenotype with genetic findings to achieve accurate diagnoses and guide management effectively [8].
Dravet syndrome, a severe epileptic encephalopathy, serves as a compelling success story within epilepsy genomics. The identification of its genetic cause, primarily involving SCN1A mutations, has enabled precise diagnosis, prognostication, and the development of targeted therapeutic strategies, showcasing the profound impact of genomic discoveries [9].
Finally, the transformative potential of whole genome sequencing (WGS) in epilepsy is undeniable. WGS offers a comprehensive view of genetic variations, including structural variants and non-coding regions often missed by other methods, leading to a higher diagnostic yield and fostering advanced precision medicine approaches for complex epilepsy cases [10].
Genomics has fundamentally revolutionized the landscape of epilepsy diagnosis, understanding, and management, marking a pivotal shift in how clinicians approach this complex neurological disorder. The growing role of genomics in diagnosing and managing various epilepsies is undeniably evident, with genetic testing now recognized as crucial for identifying underlying causes, guiding tailored treatment strategies, and offering vital prognostic information, particularly in pediatric and early-onset cases where early intervention can be critical [1]. This transformation moves significantly beyond traditional phenotyping, leveraging profound genomic discoveries that have reshaped our comprehension of both well-defined monogenic forms and the intricate polygenic architecture underlying common epilepsies. Consequently, genetic findings are increasingly vital for precise diagnosis, refined classification, and the development of highly personalized treatment approaches [2].
The evolution of precision medicine in epilepsy is directly and largely driven by these rapid genomic advancements. Identifying specific genetic etiologies enables the application of highly targeted therapies, which often results in remarkably improved seizure control and better management of associated comorbidities, enhancing overall patient quality of life [3]. While the therapeutic potential is immense and actively being explored, challenges persist in broadly implementing precision medicine, including issues related to equitable accessibility of advanced testing and the complex interpretation of vast genetic data [3]. Furthermore, the exciting development of novel genetic therapies, such as sophisticated gene therapy techniques, antisense oligonucleotides (ASOs), and cutting-edge CRISPR/Cas9-based strategies, highlights their profound potential to directly address underlying genetic defects. These emerging treatments promise to provide precise, disease-modifying interventions for previously intractable forms of epilepsy, offering new hope to patients [6].
Diagnostic methodologies have undergone significant advancements, presenting clinicians with a wider array of sophisticated genetic testing modalities. These now prominently include targeted gene panels, comprehensive exome sequencing, and the increasingly utilized whole-genome sequencing (WGS), all of which contribute to a substantially higher diagnostic yield by providing an exceptionally comprehensive view of genetic variations. This includes critical structural variants and non-coding regions that are often missed by less thorough methods [8, 10]. A practical guide designed for clinicians underscores the paramount importance of accurately interpreting these complex results and integrating thoughtful genetic counseling, emphasizing how precise genetic information can profoundly refine diagnosis, accurately predict prognosis, and critically inform treatment decisions, especially for patients presenting with rare and complex epilepsy syndromes [5]. The seamless integration of a patient's clinical phenotype with their specific genetic findings is thus rendered absolutely critical for achieving the most accurate diagnoses and guiding effective management strategies [8].
Genomics has, furthermore, shed considerable light on the most severe forms of the condition, such as the devastating epileptic encephalopathies. Next-generation sequencing technologies have proven instrumental in the rapid identification of numerous causative genes for these conditions, leading to a much deeper understanding of their underlying disease mechanisms and significantly paving the way for the development of highly targeted therapies. This progress occurs even though a substantial number of cases still unfortunately await a clear genetic diagnosis [4]. A particularly notable and inspiring success story in the realm of epilepsy genomics is Dravet syndrome. The timely identification of its primary genetic cause, predominantly involving SCN1A mutations, has profoundly advanced precise diagnosis, allowed for more accurate prognostication, and critically enabled the development of targeted therapeutic strategies specifically for this severe epileptic encephalopathy, representing a landmark achievement in genomic medicine [9].
Looking back, the historical progress and current trajectory of epilepsy genetics illustrate a profound journey that spans from the initial discovery of single epilepsy genes to the contemporary era of high-throughput sequencing. This rapidly evolving landscape critically underscores the immense promise of personalized medicine in epilepsy care [7]. With genetic insights fundamentally transforming epilepsy classification, enhancing prognostic accuracy, and accelerating the development of novel targeted therapies, the future appears promising. The transformative potential of WGS, offering a new era of diagnosis and precision medicine, continues to drive advancements, ensuring a more tailored and ultimately more effective approach to epilepsy care for individuals worldwide [10].
Genomics has profoundly transformed epilepsy care, establishing a new paradigm that moves beyond traditional phenotyping to integrate advanced genetic testing for precise diagnosis, refined classification, and highly personalized treatment strategies. Genetic testing modalities, including whole-exome and whole-genome sequencing, are now recognized as crucial for identifying underlying causes, effectively guiding treatment, and offering vital prognostic information, particularly in pediatric and early-onset cases where timely intervention is critical. These significant genomic advances have enabled the rise of precision medicine, allowing for the application of targeted therapies specifically tailored to genetic etiologies, which in turn improves seizure control and aids in the better management of associated comorbidities. The field is also witnessing the exciting development of novel genetic therapies, such as sophisticated gene therapy and antisense oligonucleotides (ASOs), which hold immense promise for providing disease-modifying treatments that address the root genetic defects. Genomic insights have considerably deepened our understanding of severe conditions like epileptic encephalopathies and have yielded notable success stories, such as in Dravet syndrome, where the identification of SCN1A mutations has directly guided precise diagnostic and targeted therapeutic strategies. While current diagnostic approaches widely utilize gene panels and exome sequencing, whole-genome sequencing is increasingly offering a more comprehensive view of genetic variations, significantly enhancing diagnostic yield and actively fostering advanced precision medicine approaches. Despite the ongoing challenges, including accessibility to testing and the complex interpretation of vast genetic data, the continually evolving landscape of epilepsy genomics points strongly toward a future of increasingly personalized, effective, and transformative epilepsy management.
