Although our study revealed Dyrk1A presence in the hippocampal postsynaptic fraction and previous studies showed DYRK1A overexpression in DS, our data suggest that Dyrk1a-mediated phosphorylation GluN2A(pS1048) might contribute to DS synaptic alterations, a hypothesis that might be explored in the future. This evidence concerns the gene GRIN2A and Dravet syndrome.
