  • Genotype phenotype analysis and clinical research of 95 cases of children with epilepsy

    ObjectiveWe have summarized the clinical features of some refractory or genetically related children with epilepsy in clinical diagnosis and treatment and carried out the two generation of high-throughput gene sequencing and generation of verification on them. To analyze the relationship between mutant genes and epilepsy, to understand the genetic pattern of children and to look for possible pathogenic or disease causing mutation.MethodsEstablish a complete pedigree database for 95 children and their parents diagnosed in pediatric neurology clinic in our hospital from septeuber 2014 to Deceln ber 2016, and carry out gene testing on them by using two generation high-throughput gene sequencing. Then we have the analysis on the basis of clinical features and gene type in children.ResultsRefractory or genetically related children had a smaller age range and had a variety of clinical features. Most of them (47/95, 49.5%)needed two or more drugs for treatment; 28.4% of them was controlled which was about 27cases; 21.1% of them was effective which was about 20 cases; 33.7% of them was marked which was about 32 cases; 12.6% of them was of no effect which was about 12 cases; 4.2% of them was missed which was about 4 cases. a small number of children (18/95, 18.9%)had poor prognosis and accompanied with exercise and mental retardation. Genotype detection results: pathogenic genes of total 16 cases (16.8%)were cleared; there were about a total of 21 cases (22.1%)of possible pathogenic gene; there were about a total of 30 cases (31.6%)of non pathogenic gene; a total of 28 cases were not detected mutated gene which was about 29.5%.ConclusionsWe have found two new virulence gene of CASK and BRAF which had few reports in China and expanded the number of genes associated with neural development and epilepsy associated genes; the clinical characteristics of SCNIA gene mutations in Dravet syndrome were more serious which include earlier onset, frequent seizures and poor treatment effect; most children with specific causative genes required the combined use of two or more Anti-epileptic drugs, which has difficulties in treatme.
