Özet
Background Advancement in genetic technology has led to the identification of an increasing number of genes in epilepsy. This will provide a lot of information in clinical practice and improve the diagnosis and treatment of epilepsy. Aim To show the importance of genes in the next-generation sequencing (NGS) panel during the evaluation of epilepsy and to emphasise the importance of genetic studies in different populations for the evaluation of genes that cause disease. Methods This was a single-centre retrospective cohort study of 80 patients who underwent NGS testing with a customised epilepsy panel. Results In a total of 54 (67.5%) out of 80 patients, pathogenic or likely pathogenic variants and variants of uncertain significance (VOUS) were identified according to the American College of Medical Genetics and Genomics criteria. Pathogenic or likely pathogenic variants (n = 35) were identified in 29 (36.25%) out of 80 individuals. VOUS (n = 34) were identified in 28 (35%) out of 80 patients. Pathogenic, likely pathogenic and VOUS were most frequently identified in TSC2 (n = 11), SCN1A (n = 6) and TSC1 (n = 5) genes. Other common genes were KCNQ2 (n = 3), AMT (n = 3), CACNA1H (n = 3), CLCN2 (n = 3), MECP2 (n = 2), ASAH1 (n = 2) and SLC2A1 (n = 2). Conclusions NGS-based testing panels contribute to the diagnosis of epilepsy and might change the clinical management by preventing unnecessary and potentially harmful diagnostic procedures and management in patients. Thus, our results highlight the benefit of genetic testing in children suffering with epilepsy.
