â¢It contributes to better recognition of the electroclinical pattern of KCNA2-early-onset epileptic encephalopathy.â¢It contributes to better management of early-onset-epileptic encephalopathy.â¢It emphasizes the importance of molecular studies as early investigation in early-onset epileptic encephalopathy.
BackgroundRecently, de novo loss- or gain-of-function mutations in the KCNA2 gene; have been described in individuals with epileptic encephalopathy, ataxia or intellectual disability.Case descriptionIn this report, we describe a further case of KCNA2-early-onset epileptic encephalopathy. The patient presented since birth with intractable seizures, progressive microcephaly, developmental delay, and progressive brain atrophy. Whole-exome sequencing showed a novel de novo mutation in the KCNA2 gene: c.1120A > G (p.Thr374Ala).ConclusionThis case expands the genotypic and phenotypic disease spectrum of this genetic form of KCNA2-early onset epileptic encephalopathy.
