The fast pace of gene discovery has resulted in groundbreaking advances in the field of epilepsy genetics. Clinical testing using comprehensive gene panels, exomes, or genomes is now increasingly available and has significantly increased the diagnostic yield for early-onset epilepsies and enabled precision medicine approaches. In this paper, we report a case of epilepsy in a pedigree. The proband had heterozygous mutations in (NM_001112741.1:c.959G>A, p. Arg320His), (NM_000070.2:c.526G>A, p. Val176Met), and (NM_021076.3:c. 2595 delC, p. Lys866Argfs51). Sanger sequencing verification was consistent with the results of whole-exome sequencing. The mutation was a mutation, and the and mutations were inherited from their father and mother, respectively. Based on the American College of Medical Genetics and Genomics (ACMG) guidelines, a heterozygous mutation was found for (NM_000384.2: c.10579C > T, p. Arg3527Trp). The heterozygous mutation at this site was inherent in the pedigree. Coexpression analysis indicated that heterozygous mutations of , and were closely related to the clinical phenotypes of the patient, and the clinical phenotypic heterogeneity of the disease may be the result of the interaction of multiple genes.
基因发现的快速发展在癫痫遗传学领域带来了突破性进展。如今,使用综合基因检测板、外显子组或基因组进行的临床检测越来越普遍,显著提高了早发性癫痫的诊断率,并推动了精准医学方法的应用。在本文中,我们报告了一个家系中的癫痫病例。先证者在[基因名称1](NM_001112741.1:c.959G>A,p.Arg320His)、[基因名称2](NM_000070.2:c.526G>A,p.Val176Met)和[基因名称3](NM_021076.3:c.2595delC,p.Lys866Argfs51)中存在杂合突变。桑格测序验证结果与全外显子组测序结果一致。[基因名称1]突变是一个[具体突变类型]突变,[基因名称2]和[基因名称3]突变分别从其父亲和母亲遗传而来。根据美国医学遗传学与基因组学学会(ACMG)指南,在[基因名称4](NM_000384.2:c.10579C>T,p.Arg3527Trp)中发现了一个杂合突变。该位点的杂合突变在该家系中是固有的。共表达分析表明,[基因名称1]、[基因名称2]和[基因名称3]的杂合突变与患者的临床表型密切相关,疾病的临床表型异质性可能是多个基因相互作用的结果。
