| Abstract: | Objective To study the clinical diagnostic characteristics of children with epilepsy combined with febrile seizures plus(EFS+)caused by SCN1A gene mutation and to provide a theoretical reference for diagnosis and treatment.Methods A total of 46 children with EFS+who were admitted to Jinhua Hospital Affiliated to Medical College of Zhejiang University from May 2018 to May 2021 were selected as participants.The second-generation high-throughput gene sequencer was used to detect SCN1A gene mutations in children,and the clinical diagnostic characteristics of patients with different SCN1A genotypes were compared.Results A total of 46 children with EFS+had an initial age of 12-18 months.Among them,36 cases of SCN1A gene mutation were positive,and the mutation rate was 78.26%,including 18 cases of mis-sense mutations,18 cases of truncation mutations.Truncation mutations included 3 cases(8.33%)of splicing mutations,10 cases(27.78%)of frameshift mutations,2 cases(5.56%)of large fragment deletions and 3 cases(8.33%)of non-sense mutations.A heterozygous mutation(nucleotide change c.1499A>G)was found in the SCN1A gene of the tested child,and the 1499th nucleotide in the coding region was changed from G to T,resulting in the 946th amino acid being changed from Arg to Cys,that was p.(Arg946Cys).A heterozygous mutation was found in the SCN1A gene of the tested child(nucleotide change was c.2891T>G),and the 2891st nucleotide in the coding region was changed from T to G,which changed amino acid 542 from the original leucine(L)to arginine(R),namely,p.L542R.This mutation was a mis-sense mutation.The mutation sites were distributed in the DⅡS5-S6 junction loop of the sodium channel alpha subunit protein domain,which was not a polymorphic change.Conclusion Children with EFS+are at high risk of SCN1A gene mutations,and the phenotypic characteristics of children with febrile seizures plus are closely related to the type and location of SCN1A gene mutations,which can provide a targeted reference for clinical diagnosis and treatment. |
