摘要: Epileptic encephalopathies are a devastating group of epilepsies with poor prognosis, which the majority unknown etiology. We perform targeted massively parallel resequencing 19 known and 46 candidate genes for epileptic encephalopathy in 500 affected individuals (cases) to identify new involved investigate phenotypic spectrum associated mutations genes. Overall, we identified pathogenic 10% our cohort. Six had 1 or more variants, collectively accounting 3% show that de novo CHD2 SYNGAP1 causes encephalopathies, 1.2% 1% cases, respectively. also expand spectra explained by SCN1A, SCN2A SCN8A mutations. To knowledge, this is largest cohort cases undergo resequencing. Implementation rapid efficient method will change diagnosis understanding molecular etiologies these disorders.
