Epilepsy is a neurological disease that is mostly caused by genetic factors. The genetic diagnosis of patients in a pediatric epilepsy cohort was provided.
After phenotypic characterization, a 48-gene Next Generation Sequencing panel was performed in 110 Turkish children with epilepsy. The variants were called and annotated using the QIAGEN Ingenuity® Variant Analysis software.
Of those carrying pathogenic mutations, two patients had mutations in the SCN1A gene and two patients in the TSC2 gene; other patients had mutations in the SCN1B, GRIN2B, KCNQ2, PCDH19, CHRNA2, and MECP2 genes. In total, nine out of 10 patients had pathogenic variants that were not previously reported.
The genotype-phenotype correlations of these variants were discussed by comparing the clinical findings with the literature.
癫痫是一种主要由遗传因素引起的神经系统疾病。本研究对儿科癫痫队列中的患者进行了基因诊断。
对 110 名土耳其癫痫儿童进行表型特征分析后,采用 48 基因下一代测序panel 进行检测。应用 QIAGEN Ingenuity® Variant Analysis 软件对变异进行分析和注释。
在携带致病性突变的患者中,2 例患者的 SCN1A 基因突变,2 例患者的 TSC2 基因突变;其他患者的 SCN1B、GRIN2B、KCNQ2、PCDH19、CHRNA2 和 MECP2 基因突变。总共,10 例患者中有 9 例为之前未报道过的致病性变异。
通过将临床发现与文献进行比较,讨论了这些变异的基因型-表型相关性。
