Dynamin-1-like (DNM1L) is a gene located on chromosome 12p11.21 that encodes for dynamin-related protein (DRP1), a GTPase involved in mitochondrial and peroxisomal fusion, which plays a pivotal role in brain development. The missense variant, p.Arg403Cys, is clinically associated with childhood-onset super-refractory status epilepticus, with either subsequent poor neurological outcome or death (described in 13 patients). We present a 20-year-old girl carrying this mutation with a history of two episodes of super-refractory focal myoclonic status epilepticus which manifested as epilepsia partialis continua (EPC) with a 13-year interval, during which she displayed moderate intellectual disability, social and school reintegration, without complete control of myoclonic manifestations...
