An accumbal cholinergic ISR-HCN2 axis sustains maladaptive cue motivation

Gene therapy with doxycycline-controlled expression of human Kv1.1 reduces neuronal excitability and increases sociability of Scn2a-deficient mice

Genetic loss-of-function (LoF) variants in SCN2A, a gene encoding the voltage-gated sodium channel Nav1.2, have been identified as one of the foremost monogenic causes of autism spectrum disorder (ASD). ASD encompasses a broad spectrum of behavioral phenotypes, with impaired sociability as a core characteristic. We hav...

Epilepsy-associated SCN2A-L1342P mutation drives network hyperexcitability and widespread transcriptomic changes in human cortical organoids.

These findings demonstrate that the Nav1.2-L1342P mutation drives a multifaceted disease phenotype, including network hyperexcitability and disruption of pathways related to neuronal and synaptic functions, which advances understanding of SCN2A-related developmental and epileptic encephalopathy (DEE).
