Abstract
Developmental delay and seizures with or without movement abnormalities (DEDSM) is a neurodevelopmental phenotype associated with monoallelic mutations in the DHDDS gene. We report a novel case of DEDSM linked to a DHDDS variant (c.614G > A, p.Arg205Gln) in a 45-year-old Brazilian patient presenting with refractory epilepsy, ataxia, dystonia, parkinsonism, and global developmental delay. This is the first case to associate a DHDDS variant with hippocampal atrophy on neuroimaging. After adjustments in anticonvulsant therapy, seizure control was achieved, and the patient-who was previously unable to walk due to frequent falls attributed to myoclonic jerks-showed significant improvement in gait and mobility.
期刊介绍：
Neurogenetics publishes findings that contribute to a better understanding of the genetic basis of normal and abnormal function of the nervous system. Neurogenetic disorders are the main focus of the journal. Neurogenetics therefore includes findings in humans and other organisms that help understand neurological disease mechanisms and publishes papers from many different fields such as biophysics, cell biology, human genetics, neuroanatomy, neurochemistry, neurology, neuropathology, neurosurgery and psychiatry.
All papers submitted to Neurogenetics should be of sufficient immediate importance to justify urgent publication. They should present new scientific results. Data merely confirming previously published findings are not acceptable.
