Abstract
Neurodevelopmental disorders, can be caused by mutations in neuronal genes fundamental to brain development. These disorders have severe symptoms ranging from intellectually disability, social and cognitive impairments, and, a subset are strongly linked with epilepsy. In this review we focus on those neurodevelopmental disorders that are frequently characterised by the presence of epilepsy (NDD+E). We loosely group the genes linked to NDD+E with different neuronal functions: transcriptional regulation, intrinsic excitability and synaptic transmission. All these genes have in common a pivotal role in defining the brain architecture and function during early development, and when their function is altered symptoms can present in the first stages of human life. The relationship with epilepsy is complex. In some NDD+E, epilepsy is a co‐morbidity and in others seizures appear to be the main cause of the pathology, suggesting that either structural changes (NDD) or neuronal communication (E) can lead to these disorders. As well as grouping the genes that cause NDD+E, we review the uses and limitations of current models of the different disorders, and how different gene therapy strategies are being developed to treat them. We highlight where gene replacement may not be a treatment option, and where innovative therapeutic tools, such as CRISPR‐based gene editing, and new avenues of delivery are required. In general this group of genetically‐defined disorders, supported increasing knowledge of the mechanisms leading to neurological dysfunction serve as an excellent collection for illustrating the translational potential of gene therapy, including newly emerging tools.
